The impact of rust on the marble which

After processing of ordinary rocks to become commonly used by well marble products, the rock is composed of a variety of minerals, including iron-containing minerals is a mineral. Iron compounds in nature, most of the way to the emergence of iron easily at high temperatures and oxygen, sulfur, chlorine and other elements of a chemical reaction, and soluble in inorganic acid and concentrated granite acid medium.

    Only the form of iron compounds appear to survive in nature. Iron compounds have the following four compounds:

    First, the iron oxide.

    Second, iron sulfide.

    Third, iron silicate minerals.

    Fourth, iron carbonate minerals.

    Because the marble itself, such as hematite or pyrite, such easily oxidized iron minerals and corrosion itself, causing the marble surface discoloration and rust and other diseases, or more seriously, due to iron corrosion resulting from crystalline particles burst. Here iron minerals on the impact of the marble itemized description:

    First, the impact of iron minerals in addition to the granite iron sulfate minerals, most of the iron minerals are likely to exist in the form of chemical formula granite. Iron silicate minerals are the number and distribution of iron minerals most widely, followed by iron oxide. The darker the color of iron minerals, granite, decorative appearance of the critical value of impact. Concentration of those minerals in the dark granite, marble often has a black or green lines. Pyrite, marcasite embedded in iron minerals such as gabbro, formed a flashing gold black gold marble.

    Second, iron sulfide is yellow rust granite suffered major cause of pollution, iron sulfide weathering in easily hydrolyzed under normal temperature and pressure, the first generation of iron oxide, and water into limonite. Will leave after the decomposition of iron sulfide pyrite cube illusion, and some dissolved into a number of holes. If the iron oxide solution infiltration along the fracture dip, to form thin films of iron, make marble contamination, reduce gloss of marble decorative effect. Granite in the second cause of the damage to black mica, flake easily organized and easy to peel along the surface of weathering, the formation of pits.

    Third, the marble in the iron carbonate minerals are iron, iron sulfide, iron oxide and iron silicate minerals. The iron minerals in the marble due to the different components of the role of the marble very different. Gray marble can ankerite, amphibole minerals are green, spotty, linear distribution of a certain pattern when the rich have their own color changes; chlorite make green marble. Subjected to surface rust and yellow marble was originally due mainly pyrite, pyrrhotite followed, such as iron sulfide minerals, the pollution causes the same granite. Clean cleaning company

    Fourth, the chemical composition of marble, iron components, although not completely determine the level of the security level of the marble, but it is most of the marble itself is the main reason for rust occurs, the safety of the marble can be quite large. It is all iron minerals and iron oxide attached to the marble surface, the total iron content. Either granite or marble marble, if to compare the stability of iron minerals containing iron-containing silicate mineral-based, rather than iron and iron sulfide film, the marble is with a strong wind resistance; contrary, if the marble in the Most of the unstable iron sulfide minerals such as iron, despite the low iron content, the ability of marble less wind resistance.

    Whether it is marble or granite, determines the stability of iron minerals marble weathering capabilities. Iron sulfide is the most volatile components, biotite ranked second, moreover lutetium Slate ore and chlorite minerals.
