471-34-1


Description

Light calcium carbonate is produced by chemical processing. Since its sedimentation volume (2.4-2.8 mL/g) is larger than the sedimentation volume of heavy calcium carbonate produced by mechanical methods (1.1-1.9 mL/g), it is called light calcium carbonate.

 

Application  

(1) Calcium carbonate is one of the earliest and largest fillers used in the rubber industry.

(2) Calcium carbonate can play a skeleton role in plastic products, and has a great effect on the dimensional stability of plastic products, can improve the hardness of the products, and can also improve the surface gloss and surface flatness of the products.

(3) Calcium carbonate is a large amount in the paint industry, and it is an indispensable skeleton. The amount of the calcium carbonate is more than 30%, the phenolic enamel is 4-7%, and the phenolic fine pattern wrinkle paint is more than 39%.

(4) In the application of water-based coating industry, it is more widely used, which can make coatings not settle, easy to disperse, and have good gloss. The amount of water-based coatings is 20-60%.
