Application of Nano activated calcium carbonate

1. In plastics, it can improve the dimensional stability, hardness and rigidity of plastic products, and improve the processing performance of plastics and the heat resistance and astigmatism of their products;
2. As a filler in rubber, it can increase the volume, reduce the cost, improve the processing performance and vulcanization performance;
3. In papermaking, it can be used as a filler for paper, a white pigment for coated paper, a filler for calcium plastic paper, etc.;
4. As a filler in paint, it can act as a skeleton, so it is called "exterior pigment"; in oil-based paint, the filling amount can reach 10-50%, and the filling amount in water-based paint can reach 10-20%.
Nano activated calcium carbonate is the base material, which is made by modifying and activating the surface of the inorganic powder by using multifunctional surfactants and complex high-efficiency processing aids. The modified calcium carbonate powder forms a special cladding structure on the surface, which can significantly improve the dispersibility and affinity in the polymer matrix such as polyolefin, and can form an interface with the polymer matrix It can improve the impact strength of products. It is an incremental filler with excellent performance. The filling amount is generally 30-100%, and some products are even more than 100 parts.
