3000mesh Light Calcium Carbonate

Light calcium carbonateCharacter description: white powder or colorless crystal. No smell. Tasteless. Decomposition of 825 to calcium oxide and carbon dioxide. Soluble in dilute acid and release carbon dioxide, insoluble in alcohol. There are two kinds of crystallization, is an orthorhombic crystal aragonite, a rhombohedral calcite crystal is six. Calcite, with irritation.Storage and transportation: density: 2.711 melting point of 1339 DEG C:Instructions for use: verification and determination of halogen organic combination reaction, and ammonium chloride with decomposition of silicate prepared calcium chloride solution to standardized liquid soap, water analysis and verification of phosphorus. Manufacturing optical Nd glass raw materials.The role of light calcium carbonate and its use is very wide, can be used in the following industries:Rubber industry: calcium carbonate is industrial rubber used in the earliest volume one of the largest filler, a large number of calcium carbonate filled in rubber, can increase the product volume, in order to save expensive natural to reduce costs, the calcium carbonate filled rubber can obtain higher than pure sulfide rubber tensile strength and wear resistance, tear strength and in the natural rubber and synthetic rubber have a significant reinforcing effect, also can adjust the consistency.Plastics industry: calcium carbonate in the plastic products can play a role in skeleton and the stability of the size of the plastic products have great effect, improve product hardness, can also improve product surface gloss and surface smoothness. In general plastic products to add calcium carbonate heat resistance can be improved, due to the degree of more than 90% of calcium carbonate, can also replace the expensive white pigment played a certain role in whitening.Paint industry: calcium carbonate in the paint industry in the larger amount, is an indispensable skeleton, in the thick paint dosage for more than 30%, phenolic enamel 4-7% phenolic fine pattern wrinkles paint 39% above.Water based coatings industry: in the application of water-based paint industry, the use of more widely, can make the paint is not settlement, easy dispersion, good gloss and other characteristics, the amount of water in the paint for 20-60%.In addition, calcium carbonate in the paper industry plays an important role to ensure that the paper's strength, whiteness, low cost. In the cable industry can play a role in insulation.Calcium carbonate in the plastic products can play a role in the skeleton, the size of the plastic products have a great effect on the stability, can improve the hardness of products, can also improve the surface gloss and surface smoothness of the products. In general plastic products to add calcium carbonate heat resistance can be improved, due to the degree of more than 90% of calcium carbonate, can also replace the expensive white pigment played a certain role in whitening.The product whiteness, high purity, good fineness, higher than the performance of the products in the same industry, improve the quality of downstream products, widely used in rubber, plastics, PVC pipes, profiles, paint, paper, paints, sealants, daily necessities, medicine and other industries.
