Granite paving the high rate of hardening

Square spread granite, beautiful and beautiful, but beauty is beauty yi, its permeability was generally, increased the pavement drainage pressure, may also bring in KuXia heat island effect. In my spare time, I like ponder the tin city urban construction problems before people to the author suggest Mr Pan, part of square, pedestrian street of public places such as road sclerosis rate on the high side, should cause the attention of related departments.

In Mr Pan's suggestion, the author of taihu international city to gold MianPu discover all the square is slippery hard stone material surface. Square a few big tree before, but the left without any were to block a large area. A long-term clean job in this responsible for the maintenance staff said: "to summer washed-up, hot badly, greening and less tan, pavement." the addition, dazzling The square before bluestone road, the afforested area are small and open a wide road only 1.5 meters of rectangle flowerpot, and 1.5 meters square, each spaced 3 meters green points. The flower beds, peripheral build by laying bricks or stones inside the plant is granite branches is sparse. Mr Pan said: "this situation, it is easy to create heat island effect."

Concerned expert analysis, more and more city place to use tidy beautiful stone plate pave the ground. "Super luxurious decoration", pavement although beautiful, but the biggest drawback is impervious, increased the road drainage pressure. Meanwhile, the rain from surface erosion or evaporated, make pavement dry, aggravating the dust pollution. In addition, road sclerosis attract, storage and reflecting the sun's heat, make the ground average temperature rise, increased greatly for cooling energy consumption. Hardened road will also cause many environmental and ecological negative effects, such as make pavement air exchange capacity reduction, more urban heat island effect formed.

For road sclerosis, zhuhai's authorities have noticed the problem Slate, actively raise the. From municipal departments that eight years ago, zhuhai early in the sidewalk promotion permeable type SuBo Locke brick, so far, the city sidewalks basic use permeable type brick. In recent years, is still in LiangXi bridge from LiangXi road to ramps, for a sidewalk fengxiang bridge, using a new type of permeable type concrete, permeable rate higher. The pressure to carry little sidewalks, can use permeable profile hostages, but traffic motor lane, susceptive pressure is strong, still need strong hardened road. But in order to further reduce the noise, reduce pavement seeper, zhuhai had faith in motor vehicle test planning asphalt pavement spread permeable. Construction department, says that zhuhai have relevant approval requirement residential projects, commercial projects to avoid using permeable type brick, but no compulsory measures.

Highly-socialized SLATE

From the perspective of geology, "Slate" is a kind of metamorphic rock. According to the structural classification, bad rock have 1000 pieces of rock, shale and gneiss, SLATE, etc. The plate tectonic rock called with SLATE. Namely that a concept: "SLATE" is metamorphic rocks with tectonic plate, the petrological characteristics. But in real life, people familiar with the "SLATE" content is very wide. More of the time was called "SLATE", "SLATE", it is a kind of the name of the commodity. As long as can be processed into flake or plate containing natural characteristics of the stone are called "SLATE". Most of the SLATE durability are strong, acid and alkali resistant.

SLATE classification:

Natural SLATE press utility cent: a floor, watts board, wallboard, table-board;

Color-coded score: there are green, grey, black, red, purple, brown, yellow, rusty;

According to lithologic points: have shale board, siliceous board, carbonaceous board, quartz qualitative board;

Press processing finished product points: organic cutting board, disorderly type board;

According to SLATE corrosion resistance points: there is an acid plate and don't fight acid board. Acidoresistant is measured a SLATE is suitable for roof tiles on board one of the most important criteria.

SLATE usage:

Such material is more straightforward, more can reflect the characteristics of the stone, the general area bigger area, can be used to use the floor and part the adornment of metope, the small area only as ornament use, can appear otherwise depressed. SLATE itself has an irregular shape and uneven shape characteristic, general art work in pursuit of tide and personality crowd like this style of stone. When use, consider stone itself color is tie-in, now dark grey stone use majority.

SLATE buy:

Quality SLATE, won't have too much noise, and colour distribution is evener, no suddenly thick and thin phenomenon, petting SLATE surface without rough feel. SLATE of choose and buy also want to pay special attention to radioactive standard numerical, according to the national standards in indoor use, A kind of stone.

Natural marble decoration

Natural marble, granite plank as a kind of high-grade times metope adornment material, it has a long history, it is a kind of old, traditional facing material, its surface smooth, delicate as mirror general, give a person with noble, elegant visual effect. Meanwhile, its wear-resisting performance is good, easy cleaning. Marble, granite plank is belonged to the natural stone material, but its performance differences, how to correctly chosen reasonably, relationship to adornment effect are satisfied, the question whether use period for.

Marble texture is close-grained, surface hardness is not big, can be processed to burnish, it is a kind of metamorphic rocks, mainly composed by calcite and dolomite. Marble has gray, green, red, black and so on many kinds of colors, with a beautiful figure.

Granite rocks, by the deep tectonic density, make compressive strength high, porosity and bibulous rate is extremely low, cold resistant good wearproof ability, good resistance to weathering. Granite is dacheng rock's most widely distributed in rock, is a kind of typical deep rock, its main mineral extremely for feldspar and quartz and a small amount of mica, color is usually gray, fleshy red, grey red and white color, etc.

Marble, granite, when decorate plank of attentive protection, when upright handling marginal landing, avoid positive marginal ground first; Also want to avoid ground first corner. Size larger Dali or granite slab, unfavorable flat shipped, to prevent produced by the moment because gravity, in recent years, and the fractured in marble, granite plank decoration process, because unit area is big, metope juncture less, adornment effect is good, so the whole after processing unit area of trend is large, but family bedroom adornment or unit area not too big. In custody period, because have certain gap between marble, particles have certain dyeing force, meet non-ferrous dye body, can penetrate absorption. Therefore, to prevent acid-base kind, chemicals, colored dye body direct contact with smooth.

Marble and granite plank for itself is heavier, for security firm, on installation take plank and grassroots tied or hang, then grouting fixed method, all of the more than 1.2 meters height adornment, all should use wire bundle, general approach is at the grass-roots level surface welded steel mesh, the diameter size corresponding reinforcement and the grass-roots embedment parts or welded tube expanding luozhu, plank with the binding reinforcement of basic line tied to prison.

In addition, to clean up of the basic level, and inspection and proofreading structure obligate voids and embedment parts, embed pipe meets the design to French. Metope with how the level of verticality, with greater influence, unqualified stick where without treatment, would like to bring certain difficulties with stick. Sheet steel wire or hooking is fixed in the six reinforced online in diameter. 6 reinforced and structure in diameter embed iron or tube expanding bolt welded. Steel mesh, welded shall not have to quiver and bending phenomenon.

In the marble or granite metope with stick, such as a door window position, should first made a good door window frame, the place is proper, installation is firm, in the ordinary circumstances, box set on either side of the face, should face of flat with box.

When the installation metope, to determine the position of the first layer board, want to consider the thickness of the plank, volumetric seam width, reinforcement fabric accounts for the size and then draw the first layer board at the baseline. Will the first layer board along on the wall, under the first if there is skirting board, skirting board of elevation lines play. Choose good and have used with the plank completed binding line fixed accordingly. When the steel wire bundle or hook after work, flowing with wooden Slate of the wedgeplug tightly, and keeping a check on ruler and level feet flat slab surface flowing level status with. If there is no suitable place, can reset wedge, make the surface under the board smooth, along with mat thin skin tone is a flowing straight lead. In turn from one direction to start the installation from one end to the other end posted.

After the inspection, the sheet surface quality is eligible, began to plank and base of 3 centimeters gap between within grouting. Mortar cement with lights 2-1. 5 (sand = volume ratio). Grouting with small bucket when sewing pour into inside, don't touch dynamic SLATE, also do not only passed from one place, but spread evenly along side, a layer stone finish filling slurry, mortar initial setting rear can clean, and more than a flowing slurry yarn clean. Clean with the above mentioned procedure after install another layer SLATE, which in turn set posted over. All installation ends, getting rid of all the plaster and slurry, then use more than with panel remnants of the same colour paste embedded yi side to side wipe clean, embedded as gaps close-grained, color.

From art Angle, decorative stone facing the operator speaking, Dali is a kind of artistic creation process. Because marble a natural texture and colour difference, if you could have no regular natural texture these differs colour and ably combined, the effect can be obtained in makeup, murals, build board process, do reasonable trade-offs, original found that will lift its texture, disorderly, monarch of the short, art processing, set posted finished, give a person a kind of picture sense of completion.

The use of diamond thin circular saw blades

Diamond thin circular saw blades in the disk saw stone production has played a big role, already saved costs and improve work efficiency. Now is how to use diamond thin circular saw blades, talk about some Suggestions.

A, why should use diamond thin circular saw blades

In the disk saw stone production, how to reduce the production cost, improve the production efficiency and, of course, is the first consideration of waste materials, especially for the material rate the expensive imported especially waste material stone. Choose to use diamond thin circular saw blades, can make the waste materials stone improve the rate of 5% above the material and reduce the cost of waste materials. Also, because of circular saw granite, thinning metallutgy also thinning of the blade is saved, and save the electricity cost, water. Therefore use diamond thin circular saw blades greatly reduces the production cost, every square metre can reduce 10 ~ 40 yuan. So the circular saw blades for the diamond stone production manufacturer needs of light-weight disk saw more and more urgent.

Second, the diamond is the first key to blade sharpness

Because the thickness of the light-weight sawblade from mechanics, thinning perspective, it also weakens the rigid. In order to make have originally the standard thickness of cutting performance, except sawblade rigidity, hardness, end jump etc to reach a certain standards outside, combined the sharpness is the first diamond key. Improve the diamond by following the sharpness coping.keeping five factors decided:

1, improve the diamond, diamond choice generally the intensity of than standard with diamond head high strength 1 ~ 2kg;
2, improve the diamond coarse mesh, namely the proportion of 40/50 # ratio increased to more than 60%;
3 and reduce diamond concentration, be in commonly 25% below;
4, reasonable choice tire body formula, namely Slate easy edged sand-out low-temperature not metal binder formula;
5, shorten the length of blade, make the standard for 21mm metallutgy 24mm shorter length.

Three, reduce the input power

Because the thinning of matrix, its rigid weakens, saw blades have endurance (anti-roll) corresponding decreased; Because the width of blade thinning, length decreases, and cutting resistance reduced; Due to strengthen the sharpness, cutting blade, cutting force improve resistance. So, the original most main electromotor adopt 30kW, can change 22kW, current control in 35A or so, yield can reach the original standards.

Four, prevent thermal stress influence

Thin circular saw blades in welding metallutgy process, should try to low-temperature type silver soldering when piece, welding time hearting (silver soldering pieces so far), prevent melt appear larger heat affected zone; Welding, had better use intervals every 6, general welding gear ~ 8, a week after ordinal take welding welding.

Five, operation methods

1, first slow, quick. First cutting knife, walk slowly, drop knife depth to shallow, let it saw a straight road after 30mm depth about sawing, add go down knife knife speed depth.
2, after the first small. Such as production 600mm wide plate can be directly used to 1600mm circular saw blades one-time cut, such as production 800mm (or 900mm) wide plate, generally USES 1600mm circular saw blades, first cutting 600mm deep, after the replacement 2000mm (or 2200mm) circular saw blades, 200mm (or cutting deepen 300mm). Special attention is, now should be generally replacement blades during cutting, deepen the circle in top alignment cutting blades seam, perform the deepen after cutting, such often appear sawblade edge grinding, make a circular saw fever scrapped. Best method is to alignment cutting, sewing and then dropped to 600mm deep, will cut already cutting blades into inside, then again seam evenly, make both sides clearance adjustment, be carried out only deepen cutting.
3, according to stone hardness, reasonable use cutting depth and take knife speed. General stone high hardness, the knife knife, go to shallow depth is faster, defend the knife too deep, India red generally lower knives, walk around 8mm depth of sword speed of about 2.6 m/s.
4, fixed steering cutting. Without a fixed currently manufacturer in circular saw blades to cut, not be turned to sign, arbitrary steering cutting, so thin circular saw blades may easily "fatigue" (pending further study), the proposal with fixed to cut, we have adopted 4 years, the effect is very good.

Six, the current limit (overload) protection

Disk saw is in manufacturing process, can appear sometimes "bite saw" phenomenon, the serious influence matrix using life, especially thin circular saw blades, it matrix thin, "bite saw" unyielding, occurs when the matrix serious variant though can be back after leveling, but quality and life would have been affected. My company since 1997 LJA80 limited development and production flow controller, this product can be according to your needs, control motor current, more than you need when motor current, it can in 0.5 seconds control motor rose to rise, when you need when the current, it will automatically stop rising, so it can automatic protection diamond thin circular saw blades, and won't because current small and downtime, always won't "bite saw", can make the thin circular saw blades service life more than double.

The brightness of the photo problems about stone

stone material is used to make high-grade building adornment with, largely using its excellent physical properties and its rich color. But because the color of natural stone material is qualitative, color or formed by stone contains pigment and internal structure ion decision.

Meanwhile, composition of stone material formed by different minerals the order of different color can also affect the change, this is what we call the stone chromatism.

Therefore, when we use adornment stone material often encounter color difference. According to the stone structure and the different marble characteristics, we will have off color phenomenon finishes stone broadly grouped into the following two categories, and proposes that different solution:

A, same color stone material

The same color fastens stone means with the same structure and features, and color of the same or similar a composition stone material. For example: shandong white linen with large flowers flowers flowers flowers, with hair surface with, smooth surface and old, new, surface and belong to the same color fastens is ore-bearing layer stone. For such stone, we suggest the color difference between using "green angel" HB - S402 graces type of stone conservation agent (also called wet lubricious agent, BaoXianJi) to undertake handling. Graces type of stone conservation agent applies to the same color difference between the small stone colors appear wear, faded and adjustment, dim the phenomenon such as marble, granite, sandstone, SLATE is breathing microporous brunet type of stone material graces processing. The grace of light color stone effect is not obvious. Because after not easy grace, and I would suggest that you fast, so small experiment, confirm effect do do large area again after construction.

Second, the stone material of different color

Different color fastens stone is refers has completely different structure and features, and color ingredients completely different kind of stone or difference is very big. For example: gold thread cream-colored and new west cream-colored, Spain cream-colored with white sand cream-colored, shandong white linen and American grey porrino belong to different color between the stone. Between them, the color difference for we recommended a coloring (Slate ) to undertake handling. At present, the domestic and international stone shading methods about 20 kinds, mostly need specific equipment or field. This it is for stone conservation industry don't conform to reality. After our many years of experience, we think that use stone material colorings for coloring process is an obvious effect is simple for the convenience and good solution. However, because once the shaded stone after is not easily removed, so, the proposal consists of professional technical personnel for construction, so as to avoid unnecessary loss.

Yunfu characteristic stone profile

The first volume of yunfu stone varieties occupies the national first place, exports second nationwide, "China stone base center", "Chinese stone material circulation demonstrative base" honor, is booming yunfu stone mindset. Annual yunfu stone more than 40 million yuan RMB, the export of rmb1.6bn. The following is the introduction of characteristic stone material all yunfu.


1, man-made stone. Yunfu is the earliest start produce that man-made stone place, early in the 1980s, yunfu guangdong cloud new stone company will introduce Italy equipment start manufacture man-made stone. Yunfu cement of of all kinds ShiYingSha manufacturers many, is the country's largest production base, and white powder baishi powder is the production of man-made stone, so the important raw materials in yunfu production man-made stone, is advantageous. Especially since last year, with the rich Slate stone horse, not only adopted advanced pressure type production process, waste materials into the west has introduced the marketing management mode that, at the moment, rich YunGang stone between fame, the decoration industry in the country formed a strands of man-made stone hot, meanwhile, this "man-made stone hot" in turn promote yunfu man-made stone industry of booming development, since this year, in addition to so-called "aircraft carrier man-made stone, stone and yunfu will dolly YunGang stone, the new new intention in xingshugang stone horse in succession.

2, fireplace process such as stone. Mr. Chang is competitors in the holy characteristic made strong described in yunfu stone industry ", because as the major of fujian head stone material processing and put into production, the profit at the start collapsed, most medium-sized enterprise yunfu in stone processing to begin on pure, specially, especially ", deep "change, from plank treatment into stone processing value-added high stone material craft. In these stone material craft, again with fireplace and cylindrical processing is the most typical example, yunfu production fireplace, exported to Europe and the United States, because the opportunity of the European and American market demand, product fireplace yunfu in short supply, the fireplace is professional manufacturers mega-destroyer cannot satisfy the demand. Limestone also produce fireplace, but the QuYang drawn with domestic primarily, with import primarily yunfu. In the import marble, cream-colored elegance, deep brown nets of of primitive simplicity of grave, hole stone, wood a born beauty, is all the customers to like abroad. And cylindrical, wind water polo, stone line, etc., are yunfu advantage varieties, in all fairness, these varieties in fujian also have production, such as universal, east into four major Kings, also have production, but yunfu compared to them, our position is the "low prices, than universal than fujian technology well".

3, Mosaic. Mosaic is a card, p leyshan yunfu yunfu Mosaic is the deliverer. LiSenCai in yunfu stone, the earliest sortie cylindrical processing, and to foresee that will give the market with a revolutionary storm. Sure enough, he relies on cylindrical processing earn in the entrepreneurial road after first bucket of gold, the whole of yunfu stone processing dysmorphism excited and soon a raging fire. Then came the most intense of cylindrical processing market, Sandstone quietly exited, but in yunfu lead in developing the Mosaic craft processing service.

LiSenCai thinks, "Mosaic in countries a very long history, has formed a kind of Mosaic culture, while China's Mosaic technology startting evening. Mosaic is essentially using technology and art to make stone cutout, waste revaluation, its development space is very large, and it later is the development direction of pay more and more attention to internal art content." So he started to incumbent Mosaic of the research and exploration.

In the startup in domestic, Mosaic is still not get large-scale production and application, domestic adornment and design enterprises to Mosaic also knows little, no orders, he oneself do inventory; No technology, only oneself fumble; No market, will depend on oneself to attend the exhibition to publicize, come up to the adornment of yunfu survey and design enterprises and purchasing domestic colleague recommend introduction. It is this career to pursue, to decorate current development of confidence, the new technology of Mosaic over their confidence and make the production difficulties to market, beat the pessimistic twisting. Their efforts were not in vain, after more than a year after the winter period the market, they finally succeeded in yunfu stone hit Mosaic for the card that the customers will follow. Order increase, drive the development of the product, now has a large wholesale yunfu Mosaic manufacturer that give priority to dozen, formed quite scale of the industry, many large and medium-sized manufacturers are mount this project. As the rise of Mosaic, solved the way of leftover material yunfu zonethe stone, also for brings new profit growth point.

4, composite board. Some natural hardware scaling cost is high, in order to reduce costs and do not affect beautiful. And reduce the weight, expand stone stone scope of application, constant stone yunfu stone of compound exploration, we have developed a stone - compound stone, such as sand Anna and guangxi white compound, to reduce costs; Stone - a glass of composite, such as Norway color jade and glass composite, to enhance the transparency, protruding shows the aesthetic feeling of Norwegian color jade; Stone - wood composite, a lot of applied in furniture manufacturing; Stone - ceramic composite, such as wood yellow and ceramic composite, make wooden floor switch, make full use of leftover material, save the materials to strengthen the stiffness and strength of the product, and make the product more beautiful; Stone - concrete composite, such as the purple LuoGong and concrete composite, reduce the cost, strengthen the stiffness and strength of the product.
5, black sands big board. Mentions black sands, we will think of price war. Fujian stone manufacturers to importing granite processing is always first receive orders reprocessing plank, but black sands are exceptions, is one of a handful of one of a spot wholesale, kingdom varieties of ash saw black sands, so the application of black sands price also reduced to every square meters for 200 multivariate. Yunfu black sands how to participate in market competition? Is a gifted, or market finish rolling ZhiNanErShang, and fujian manufacturer big price war? Yunfu a stone company is relaxed pinpoint the breakthrough.

India sent long-term squat down directly from mine mine, selected waste materials, processing large 2cm thick import standards board, its black sands factory purification price can reach 70 dollars per square meter, and measurements have yunfu rules in accordance with. Because eye on China, are only this one, there is no branch, products are sold to Europe, America, has been in short supply, have even India's dirty

Analysis used in construction stone

Sand production lines used in the quality of construction stone is very important, and the quality not only comes from production line equipment and sand aggregate all production line, it lies in the quality of raw materials. How to buy natural stone becomes especially important. By forming conditions of rock can be divided into metamorphic, magmatic rocks and sedimentary rock.
Magmatite in construction stone industry in the natural stone used in granite, fai green rocks, basalt, etc.

Granite by quartz, feldspar and small amounts of mica consisting, sometimes also contain a small amount of dark minerals such as Angle flash stone, pyroxene, etc. Granite is full crystal stroma or, a massive tectonic erythema shape structure. According to different particle size, divided into crystallization granule, medium grain, coarse grained, erythema shape etc different species. Apparent density for (25 ~ 27) kg/m 3, dry compressive strength is (90 ~ 160) MPa, bibulous rate is generally less than 1%, anti-freeze label can reach F100 ~ F200 above, resistant to weathering, acid and alkali resistance performance is good, good resistance to wear, very good construction stone, facing the plank.

Fai green rock by feldspar, pyroxene or olivine, etc, to all the crystal mineral composition of grain or the fine particle structure, show massive structure. Apparent density for (25 ~ 3000) kg/m 3, compressive strength is (100 to 200) MPa, bibulous rate is less than 1%, anti-freeze properties is good. Is good facing material.

Basalt by plagioclase, pyroxene and peridot composition, show posterior vitreous crystal quality structure, or covert and often exist porosity and block or almond shape structure. Dense basalt apparent density up (2,900 ~ 33) kg/m 3, compressive strength is different because of structure fluctuates greatly, about (80 ~ 250) MPa, the density of basalt strength and durability are all very good, processing difficulties, mainly for road-building material, the bank in slope protection materials etc.

Sedimentary rock in construction stone industry in common use of natural stone: limestone, sandstone, etc.

Limestone mineral composition mainly calcite, in addition, there are oxidation silicon, dolomite and clay, etc. Generally, a qualitative structure for the crystallization of layered structure. Strength and durability are lower than granite, apparent density for 2000kg/m 3 ~ 2800kg/m 3, compressive strength is (60 ~ 150) MPa, bibulous rate for 0.1% ~ 4.5%. Wide distribution, hardness is small, mining processing easy, are widely used in building engineering and water conservancy project. But unfavorable used to contain free CO2 more or acidic higher water. Mud limestone, calcium clay rock: low strength, water resistance sent, easy weathering, cannot serve as building stone material.

Sandstone cemented by quartz sandstone that becomes cementation. Sometimes in which also have feldspar, mica and other mineral particles. Crusher sandstone is commonly, the granular structure layered structure. Name: according to different object such as oxidation silicon cemented Rachel: qualitative sandstone; Calcium carbonate cementation: gray sandstone; Iron oxide cementation: iron sandstone; Clay cementation: clayey sandstone. The sandstone performance and the content of cement type and close-grained degree relevant. Dense siliceous sandstone: apparent density up (26 ~ 28) kg/m 3, compressive strength can reach (45 ~ 100) MPa, but difficult to processing. Gray sandstone: processing easier, and its intensity can reach (60 ~ 80) MPa, is the most commonly used in sandstone. Iron sandstone behind gray matter, but can still used in sandstone secondary projects. Clayey sandstone in water softening, cannot be used in the hydraulic structures.

Metamorphic rocks in construction stone industry in common use of natural stone: gneiss, marble and quartzite, SLATE, etc.

Common gneiss is granitic gneiss, a by granite metamorphism. Mineral composition and granite similar, crystal particles is grains or a slice of erythema shape, flax, or ribbon structure. Namely light mineral quartz, feldspar and brunet mineral mica, Angle flash in stone, the ribbon is arranged, appearance is very beautiful. Apparent density for (2300 ~ 3000) kg/m 3. Richard direction perpendicular to the piece of the maximum compressive strength, can reach (90 ~ 200) MPa. Richard direction along the tablet easily mining processing, but in frozen into layer under the action of flake easily. High quality granitic gneiss basically the same purpose and the granite.

Marble is by limestone or dolostone metamorphism and become, main mineral composition is still calcite or dolomite. After the metamorphism, crystallization particles directly combined, the tectonic density, system can reach (pressure-blasting machine strength 100 to 200) MPa. Marble hardness is not big, easy machining and polished, appropriate used as building interior decoration. The durability of CO2 and acid is not high, often contact weathering, lose beautiful luster.

Quartzite is becomes by sandstone metamorphism. After the original bad particle and natural quartz sandstone that cemented to recrystallize. Homogeneous structure close-grained, intensity (100 ~ 300) MPa, durability is very high. But the hardness is big, mining processing is difficult, often in irregular massive stone used in building.

Slate is by clay shale metamorphism and into. Or In hard than shale, chopped into easily in the construction stone, thin, good durability, mainly used to cover roofs, and there are green, green, red, black, etc. Various kinds of color, used in roof rather beautiful.

Natural diamond tool specific application analysis

1, preface: diamond is a single crystals of carbon atoms, the crystal structure of the equiaxial crystal department (heart cubic face the highest density of an atomic crystal department). Because the diamond carbon atoms of a connection between key heterozygous covalent bond for sp3, therefore it has a strong adhesion, stability and direction. Unique crystal stone that makes the diamond with the nature of the highest in the material of hardness, rigid, refractive index, heat conduction coefficient and excellent wear resistance, corrosion resistance and chemical stability, etc. Excellent characteristics of natural diamond can satisfy the precision and the ultra precision cutting to the cutting tool material most requirements, is the ideal precision cutting tool materials. Natural diamond uniform grain boundary without internal crystal structure make tools of blade can theoretically achieve atomistic level straightness and sharpness, cutting cut thin ability when cutting force, high precision, small; Natural diamond hardness, wear resistance and corrosion resistance and chemical stability ensures the tools of long life, can guarantee the lasting, and reduce the normal cutting tools wear for parts because the influence of accuracy; Its high thermal conductivity and can reduce the temperature and parts of cutting the thermal deformation. Therefore, natural diamond tool material as super hard in machining area has important position and a wide range of applications, especially in ultra-precision processing areas (such as processing used in nuclear reactor and other high technology fields of various reflector, the navigation for missile or rocket computer hard disk substrate, the gyro, ultra-precision components such as accelerator electron gun), Sandstone natural diamond tool on price or whatever on the precision than the traditional processing method has obvious advantages. Table 1 for using natural diamond cutter and traditional grinding, polishing method processing various reflector precision, price comparison results.

In addition to high-tech areas outside, natural diamond tools in general industrial and civil products processing, the application of increasing also already from traditional watch parts processing development to aluminium piston, jewelry, pen, glossy plates, non-ferrous metal decoration parts processing, can say natural diamond cutter has further mechanical processing fields, plays a more and more important role.
On the other hand, due to the unique natural diamond, which makes the performance itself processing very difficult. Because of natural diamond with high hardness, must use special methods of operating workers grinding, is also high requirements; technology Because natural diamond good chemical stability, past the long-term cannot welding, only by mechanical methods of diamond, causing big particles gripping material waste and tool of diamond prices, it also influenced the precision cutting tools and parts.
For hundreds of years, scientific and technical personnel in machining of diamond tool the important role and realization method and application foreground the long-term research and development, which has yielded substantial results. Reviewed below natural diamond tool by stages, the development situation of technology introduced the Slate diamond tool tips technique, and discusses the future developing trend.

Stone Mosaic tile purposes

stone Mosaic tile can dash forward show the artistic quality and style houses. Stone Mosaic tile in Europe and Latin America, has the rich traditional USES.

Outdoor decoration

There are many aspects in outdoor stone Mosaic tile can be used. According to the surrounding landscape, can will stone Mosaic tile design used in the driveway, courtyard corridor or pool edge. These stone Mosaic tile can be big elaborate design also but important area of delicate ornament. In stone Mosaic tile on foundation of establishing fountain, can make the yard more attractive.

You can create a stone Mosaic stepping stone laid path, from garden or gazebo. If you have already laid a road, can use stone Mosaic tile as road border, let pavement become more attractive.

Interior decoration

In indoor many ways can use stone Mosaic tile. On the wall of the spanish-style house usually has pockets and portrait. These are increasing the good region stone Mosaic. You can also bathroom and kitchen tailgate Mosaic tile to design with stones.

Floor if USES Mosaic is the most wonderful thing. If you don't want the whole floor laid stone Mosaic tile, you can choose part area laid. If the entrance of the house in the use of stone Mosaic design, can reflect you are very welcome guest. In the peripheral laid Mosaic stone fireplace is the ideal design.

Furniture and household decoration

You can take the old table into stone Mosaic desktop, already beautiful use. Can be used not only to internal or external, depending on your stone types. You can also design Mosaic plates and dishes, the entire dishes are with the Mosaic is unrealistic, you can do a Mosaic edge, which will make the dishes look more attractive.

No juncture refurbished share stone technology

The so-called stone no juncture refurbished process that is already paved Slate in adjacent to color space and SLATE approximate special adhesives after treatment shall be interstitial, using professional machinery and technology to grinding, polishing processing. In this way processing passes, can appear large, whole SLATE didn't divided stone aesthetic feeling.

Stone no juncture refurbished process generally have the following steps:

1, first the stone gap between the original clean, then use the padding special stone open sewing machine to the original stone installation ZhongFeng to tidy the seam, make stone cutting open the width of bridging the gap between the poor is reduced to the minimum, reoccupy close to stone colors on the marble glue to fill. (note: if ZhongFeng processing've done before without seam is open again.

2, use close to the marble stone itself color marble glue to glue and will make the perfect toning, close to the original stone material color adequately to improve the whole feeling, to achieve optimal visual effect.

3, will adjust the good marble glue, glue filling out completely cooled because marble will have certain degree of contraction, so should make marble glue slightly higher than stone level, so not many fills.

4, adopting grinding and polishing gas-welded blades of filling agent, with stone into a horizontal plane, increase the stone, and resolve feels between the whiteness, prevent crack high-low bits back again black. Use granite refurbished machine with special cut mouth to mouth a grinding slice to cut, make its and carefully polished stone into a flat overall.

5, polishing: use special granite polishing machine, from 50-3000 number stone from coarse to fine joint piece of stone material for grinding, cause the ground shining flat as new.

6, crystallization treatment: use stone material crystalline powder and crystallization elixir cooperate burnish machine polishing, either under pressure in grinding stone and crystalline powder to occur in high temperature effect of physical and chemical synthesis reactions, form a layer of the crystallization of dense, hard protective cover. Crystal color and brightness after can enhance, also can achieve prevent slippery, waterproof, prevent oil, such as effectiveness.

After the above process, after processing gap will have very good brightness, and stone color is very close, integral feeling is very strong, and, because of marble glue be able to bear or endure corrupt, water resistant, oxidation resistance, won't produce black seam.
