Calcium carbonate

【English name】:Calcium carbonate 【Alias】:Carboni cacidcal ciumsalt;Limestone;Marble CAS19569-21-2 【Appearance】: white powder. Odorless and tasteless.

Exposed in air, no reaction, insoluble in alcohol. 【Molecular formula】:CaCO3 【Water-soluble】:almost insoluble in water or in the presence of ammonium iron oxide dissolved in water, insoluble in alcohol. 【Effectiveness of the role】: 1, the calcium carbonate is used in the rubber industry the first one of the largest big filler, calcium carbonate, among a large number of filled in the rubber, can increase the volume of products, thereby saving the expensive cost of natural rubber to reduce the purpose of calcium carbonate filled rubber sulfide can get higher than that of pure rubber, the tensile strength of abrasion resistance, tear strength, and natural rubber and synthetic rubber in a significant reinforcing effect, and can adjust the consistency.

2, the calcium carbonate in the plastic products can play the role of a skeleton, the dimensional stability of plastic products plays a significant role, can improve the hardness of products, but also can improve the products surface gloss and surface smoothness.

Add in the general plastic products can improve the heat resistance of calcium carbonate, calcium carbonate whiteness as more than 90%, you can also replace expensive white pigments play a whitening effect.

3, calcium carbonate content in the paint industry in the larger framework is essential, in the amount of thick paint in more than 30%, 4-7% in the phenolic phenolic enamel pattern of wrinkles fine paint than 39%. Play an important role in the paper industry to ensure that the paper strength, whiteness, and low cost.

In the cable industry can play a role in the insulation. 4, in the application of waterborne coatings industry, uses a more extensive settlement can not paint, easy to disperse, good gloss characteristics, in the amount of 20-60% water-based paint.

5, used in chemical building materials, with heat resistance, chemical corrosion, cold, noise, vibration, and is easily processed and other characteristics, do doors, ceiling, wall panels, down pour, stair handrails, floors and wiring, etc., in the oily coatings, TSP as a filler, can play a skeleton.
