WHAT IS STONE POWDER CACO3?

CaCO3 is a common substance, accounting for more than 4% of the earth's crust and is found all over the world in the form of chalk, limestone, marble formed from sediments of small fossil shells and oysters. and corals over millions of years. Although the above rocks are similar in chemical composition, they are quite different in terms of purity, thickness, whiteness and uniformity.

CHEMICAL COMPOSITION OF CACO3 STONE POWDER

CACO3 STONE POWDER PROCESS

After mining, limestone will classify, control and process according to closed process, then be crushed by modern technology to produce ultrafine stone particles.

Stone particles will then be put into tanks through a conveyor system to conduct acid coating.

First, uncoated stone powder will go through the mixer, dryer, vibrator and then be coated with a thin cover with steraric acid, which will eventually be put into the filter to produce the product.

APPLICATION

CaCO3 stone powder is generally widely used in many industries such as:

Paint and plastic manufacturing industry

CaCO3 powder is used as a perfect additive and main filler in the coating industry thanks to its smoothness, high brightness and low oil absorption. In addition, CaCO3 powder also has good dispersion, durability in the environment, low abrasion ability, stable pH, and enhances the anti-corrosion properties and improves product viscosity.

CaCO3 also increases the optical ability of paint and the weight of paint, so they can account for up to 60% of the paint content.

Plastic manufacturing industry

Similar to the paint industry, CaCO33's role in the plastic manufacturing industry is also a filler in the production of plastic additives PP, PE, PS. PVC...

Paper manufacturing industry

CaCO3 has two roles in the paper manufacturing industry: as fillers and as a coating agent. Using CaCO3 will help the paper to have higher whiteness, turbidity and gloss, increasing the printing ability with the lowest price.

Other industries such as:

- Detergent manufacturing industry
- Construction and construction materials
- Ceramics manufacturing industry
- Glass manufacturing industry
- Livestock industry
- Environment treatment
