1. Product performance

Shandong Caizhiyuan Pigment Technology: Light calcium carbonate is also called precipitated calcium carbonate. White powder. Odorless and non-toxic. 825 ℃ decomposes into calcium oxide and carbon dioxide. Soluble in dilute acid and release carbon dioxide.

Light calcium carbonate is obtained by chemical processing. 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.

2. Application areas

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

A. Rubber industry: Calcium carbonate is a filler in the rubber industry. Calcium carbonate is in the rubber, which can increase the volume of the product, thereby saving expensive natural rubber and reducing costs.Calcium carbonate filled rubber can obtain higher tensile strength, abrasion resistance and tear strength than pure rubber sulfide, and has a significant reinforcing effect in natural rubber and synthetic rubber, and can adjust the consistency.

B. 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 improve 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. Because the whiteness of calcium carbonate is above 90%, it can also replace expensive white pigments to play a certain whitening effect.

C. Paint industry "Calcium carbonate is used in a large amount in the paint industry and is an indispensable framework. The amount in thick paint is more than 30%, and the phenolic enamel 4-7% in the phenolic fine pattern wrinkle paint is more than 39%.

D. Water-based coating industry: The application in the water-based coating industry is more widely used, which can make the coating non-settling, easy to disperse, and good gloss. The dosage in the water-based coating is 20-60%.

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