Characteristics of light calcium carbonate powder

1. the particle shape is irregular, is monodisperse powder, mostly flocculent structure
2. Narrow particle size distribution
3.small particle size, average particle size is generally 1-3μm
4. poor liquidity, dispersion, large oil absorption value
5. The production process, equipment is more complex, high cost

Rubber

Light calcium carbonate is one of the largest filler usage in rubber industry, a lot of light calcium carbonate filler in rubber, can increase the volume of rubber products, thereby saving the cost of expensive natural rubber to reduce, the purpose of rubber to fill light calcium carbonate can obtain higher than pure rubber sulfide abrasion resistance and tensile strength, tear strength, It has remarkable reinforcing effect in natural rubber and synthetic rubber, and can adjust the consistency.

The rubber industry generally uses light calcium carbonate with a sedimentation volume of about 3.0mL/g.

Plastic industry

Light calcium carbonate can play a skeleton role in plastic products, has a great effect on the stability of the size of plastic products, can improve the hardness of plastic products, but also improve the surface gloss and smoothness of plastic products. Adding light calcium carbonate to general plastic products can also improve heat resistance, because the whiteness of light calcium carbonate is generally above 90 degrees, but also can reduce the expensive white pigment has a certain whitening effect.

The plastic industry generally uses light calcium carbonate with sedimentation volume of 2.6-2.8mL/g.

Paint industry

Light calcium carbonate in the oil coating industry, the amount is large, is indispensable skeleton, in the thick paint amount of more than 30%, phenolic enamel 4-7% phenolic fine pattern wrinkle paint more than 39%. In the water-based coating industry, the application is more widely used, can make the coating does not settle, easy to disperse, good luster, strong hiding power and other characteristics, in the water-based coating dosage of 20-60%. The coating industry generally uses light calcium carbonate with sedimentation volume of 2.6-2.8mL/g.
