Product Description

Light calcium carbonate
Character description: white powder or colorless crystal. No smell. Tasteless. Decomposition of **5 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.**1 melting point: ***9
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 the general plastic products to add calcium carbonate heat resistance can be improved due to the calcium carbonate whiteness in *0% above, you can also replace the expensive white pigment play a whitening effect.
Paint industry: calcium carbonate in the paint industry in the larger amount, is an indispensable skeleton, in the thick paint dosage for more than *0%, phenolic enamel **7% phenolic fine pattern wrinkles paint *9% above.
Water-based paint industry: in the application of water-based paint industry, more extensive use, can make the paint not settling, easy dispersion, good luster characteristics in water-based coating amount of ****0%.
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 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 the general plastic products to add calcium carbonate heat resistance can be improved due to the calcium carbonate whiteness in *0% above, you can also replace the expensive white pigment play a whitening effect.
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.
