granite Slate: Strong performance of practical and decorative use of broad

granite in today's architecture and architectural decoration industry has been widely used, has become an important building decoration materials. People on the marble, granite has been very familiar with all kinds of architectural decoration to use more. However, there are natural granite is an important partner - slate. Understand it, relatively few people use it. In fact, a better understanding of the slate, it will have broad use of space.

    Slate and marble - metamorphic rocks are igneous rocks and in the genesis (igneous rocks) and granite are essentially different. However, the formation of slate and marble and Generation of ancient geography have different conditions. Mainland slate mostly shallow continental basin metamorphic phase is to restore the environment of the resultant, so the color to dim are the main ingredients containing more sulfur. The formation of the geological environment of marble mostly wide sea, shallow, coastal oxidizing environment, the regional metamorphism diagenesis. So the main color to pale or color.

    Slate, the trade name "slate." Since ancient times, many places, people and more useful to them as roof tiles, it is also known that it is slate tile (granite). The main mineral components are quartz, sericite, chlorite, and other organic substances, carbon, sulfide material. Its chemical composition to SiO2, Al2O3, K2O, Na2O, Mn2O3, S2O3-based. Which determines the amount of SiO2 plate hardness of granite, sulfur, manganese compounds content is higher, the lower its value.

    Slate color a lot, but generally a single color. Among them, black, light green, pink and rust are most welcome. Others are still yellow, light gray, brown and so on. According to people's love and application of environmental requirements, random selection.

    Slate features and practical application of the biggest advantages is that it has on the management board - a plate tectonic. Easy to split along the board management, and split the surface is very smooth, can be directly applied to the surface decoration, eliminating the need for such as granite, marble blocks cut and polished, polishing processing. Slate board management characteristics, its decision is easy to exploit, easy processing characteristics, and thus greatly reduce its processing costs. Slate can be split along a variety of board level management of natural thickness, which :3-8mm ,8-16mm ,10-18mm ,20-28mm, in. Thickness of this natural range, can meet the construction and decoration of different types, different occasions, the use of granite plate thickness requirements.

    Our slate is rich in resources, producing more. From north to south: Liaoning, Hebei, Beijing, Tianjin, Shanxi, Shaanxi, Shandong, Zhejiang, Hubei, Hunan, Guizhou, Sichuan and other provinces are output. But ten years, who has been mining application to the outskirts of Beijing Yi County, Hebei, Shaanxi Ziyang (and Zhenba, Ping Lee, and other counties), and Sichuan, Guizhou and mainly in some areas. Geographical distribution of the slate are mostly relatively poor areas, coupled with the relatively soft texture, with a slate board management easy processing characteristics, therefore slate mining and processing enterprise technology has fallen behind, mining machinery are rarely used, so do not generally yield large, the same species can be limited to high-volume suppliers. Therefore, geological exploration has been done and has been put into production of high quality varieties, the next task should be to strengthen investment in mining and processing equipment and increase the technology content of production.

    Slate, because of its natural color, flavor, texture, uniform, hard, easy to mining and processing and stitching simple, low cost, etc., has been a lot of architecture and architectural decoration at home and abroad favored division. In recent years, both East Korean, Japanese or Western United States, Europe and other countries, needs are increasing. Followed by a practical and decorative granite plate performance for the more people understand and accept, is improving its economic value, ten years ago, manual processing (trimming machines excluded) of the black slate to 90cmX60cmX1. 5cm of the specification cases, from less than 10 yuan per square meter to the current 40-50 yuan.

    I believe the near future, the tree-lined trail in the park, in the water pool, the wall in restaurants, hotels, villas and elegant environment in the picturesque area, residential area of ​​the roof, road and people within the walls of the room, porch, balcony, bathroom slate can be seen the figure. Natural and simple, no need to add color to rock paintings of various board people's lives will also add a fun landscape.
