Nano-calcium carbonate, also known as ultra-fine calcium carbonate, is a new type of ultrafine solid powder material with a particle size between 0.01 and 0.1μm. Due to the superrefinement of nano-calcium carbonate particles, the crystal structure and surface electronic structure of nano-calcium carbonate particles change, resulting in quantum size effect, small size effect, surface effect and macroscopic quantum effect that ordinary calcium carbonate does not have.
Product characteristics
Particle size: the particle size is very small, and the distribution is very uniform, with a large specific surface area, which can reach 10-70 m²/g.
Purity and whiteness: the purity is quite high, basically above 95%, and the whiteness can exceed 96%, which is very suitable for application scenarios with high requirements for color.
Surface activity: After surface modification treatment, its compatibility with polymer materials has been significantly improved, and its dispersion is also better.
Chemical stability: at room temperature, it will not react with acids and bases, and has good weather resistance.
Application of Nano calcium Carbonate In Coating Industry
Improve the covering power: Because the nano calcium carbonate has a smaller particle size and a larger specific surface area, it can scatter and absorb light more effectively, thereby improving the covering power of the coating, so that the coating can better cover the surface of the coated material, reducing the amount of paint.
Enhanced weather resistance: nano calcium carbonate can improve the water resistance, corrosion resistance and ultraviolet resistance of the coating, so that the coating has better stability and durability under different environmental conditions, and extend the service life of the coating.
Improve rheology: It can adjust the viscosity and thixotropy of the paint, so that the paint has good fluidity and coating performance during the construction process, and it is not easy to have defects such as flow hanging and brush marks, and improve the construction quality of the paint.
