Product Description

Light calcium carbonate is also called Precipitated Calcium Carbonate. Light calcium carbonate is made by chemical processing methods. Because its sedimentation volume (2.4-2.8mL / g) is larger than that of heavy calcium carbonate produced by mechanical methods (1.1-1.9mL / g), it is called light calcium carbonate.

Light calcium carbonate has a wide range of functions and uses, and can be used in the following industries:

Rubber industry

Calcium carbonate is one of the earliest and largest fillers used in the rubber industry. Calcium carbonate is largely filled in rubber, which can increase the volume of products, thereby saving expensive natural rubber. To achieve the purpose of reducing costs, calcium carbonate can be obtained by filling rubber It has higher tensile strength, abrasion resistance and tear strength than pure rubber sulfide, and has a significant reinforcing effect in natural rubber and synthetic rubber while adjusting the consistency.

Plastic industry

Calcium carbonate can play a skeleton role in plastic products, which has a great effect on the dimensional stability of plastic products, can increase the hardness of products, and can also improve the surface gloss and surface smoothness of products. Adding calcium carbonate to general plastic products can improve the heat resistance. Since the whiteness of calcium carbonate is more than 90%, it can also replace expensive white pigments to play a certain whitening effect.

Paint industry

Calcium carbonate is a large amount in the paint industry and is an indispensable skeleton. It is more than 30% in thick paint, 4-7% phenolic enamel, and 39% phenolic fine pattern wrinkle paint.

Water-based paint industry

The application in the water-based paint industry can make the paint non-settling, easy to disperse, good gloss and other characteristics. The amount of water-based paint is 20-60%.

other

In addition, calcium carbonate plays an important role in the paper industry to ensure the strength, whiteness and lower cost of paper. It can play a certain role in insulation in the cable industry. It can also be used as a friction agent for toothpaste.
