Calcite is a kind of calcium carbonate mineral, the most common natural calcium carbonate is it. Therefore, calcite is a kind of widespread mineral. Calcite crystal shape varied, their aggregate can be clusters of crystals, can also be a granular, block, fibrous, stalactite, soil and so on. Rap calcite can get a lot of square pieces, therefore calcite. Calcite is divided into natural and small square solution, and state of ice and rock, calcite in China are mainly distributed in guangxi, jiangxi, hunan, guangxi calcite in the domestic market with high whiteness, acid insolubles less known. In the northeast region of north China will find calcite, but often accompanied by dolomite, whiteness, generally under 94, acid insolubles is too high.
Calcite color because it contains impurities, such as iron, manganese, as a pale yellow, pale red, brown, black, and so on. But more commonly is white or colorless. Colorless transparent of calcite or Iceland SPAR, Iceland SPAR is an important optical material. Calcite is the main mineral of limestone and marble, has many USES in the production and living. Calcite mohs hardness is 3, belong to easy grinding ore species, calcite processing general requirements into item number is larger, which requires grinding fineness of small, therefore, generally use ultrafine powder mill for grinding calcite. Shanghai hin the calcite processing equipment product fineness from dozens of mesh to two thousand mesh, with uniform product fineness, high flux screening rate, parts, low loss, high yield, environmental pollution-free advantages, meet the different needs of milling industry.
Calcite powder is used in artificial stone, artificial floor tile, natural rubber, synthetic rubber, coating, plastic, composite calcium new plastic, cable, paper making, medicine, toothpaste, cosmetics, glass, paint, printing ink, cable, electrical insulation, food, textile, feed, adhesive, sealant, asphalt, building materials, linoleum building, fire prevention of the ceiling and daily chemical products such as filling material.Industries can not only reduce product costs, but also can improve the function and performance of related products, increase the volume of a product, is the most versatile fan of one of the inorganic filler masterbatch. The calcite powder is added to the cable skin can improve the insulation strength of cable 5 to 10 times; If all item above car chassis coating made of calcite powder, can make the car chassis is stronger than steel of the scour prevention ability; In oil catalytic cracking, molecular sieve, detergent, cleaning agent, product modification, metal smelting, chemical synthesis, aerospace, high-temperature superconductivity, machinery manufacturing, etc. Especially in high-tech areas has the extremely widespread application. Calcite powder materials can be used as the basis of the industrial sector, and particularly large demand too. Calcite powder, therefore, become the most upstream of manufacturing industry and raw materials, contains almost all light and heavy industrial production and manufacturing sectors.
