Calcium phosphate calcium carbonate

Calcium phosphate calcium carbonate is also called super fine calcium carbonate. The standard name is superfine calcium carbonate. The most mature application of nano calcium carbonate is the plastics industry, which is mainly used in high-grade plastic products. A PVC plasticizer used for the internal seal of a car. It can improve the rheological properties of plastic masterbatch and improve its formability. The plastic packing has the effect of toughening and strengthening, improving the bending strength and flexural modulus of elasticity, thermal deformation temperature and dimensional stability, and also giving plastic heat to the plastic.
The paper industry is the most potential market for nano calcium carbonate. At present, nano calcium carbonate is also mainly used for special paper products, such as sanitary napkins for women and urine for babies. Nano activated calcium carbonate as paper filler has the following advantages: high lightness, high brightness, high brightness and whiteness of paper products; high expansibility can make paper mills use more fillers to greatly reduce the cost of raw materials; fine size, uniform, more uniform and smooth products, high oil absorption and can improve color paper Expected firmness. Calcium phosphate calcium carbonate is also used in the following industries:
1. Plastic
Main applications: PVC profiles, pipes; cords of wire and cable skin; production of PVC film (calendering film); manufacture of shoe making (such as PVC shoes and decorative patches). It is suitable for engineering plastics modification, PP, PE, PA, PC and so on.
Application characteristics: as the surface of active nano calcium carbonate is hydrophobic and hydrophobic and has good compatibility with the resin, it can effectively improve or adjust the rigidity, toughness, finish and bending strength of the products, improve the processing performance, improve the rheological properties, dimensional stability, heat stability and strengthen, toughen and toughen the heat stability. Instead of some expensive filling and aid, reduce the amount of resin, thereby reducing production costs and improving market competitiveness.
2. Rubber
Application: natural rubber, butadiene nitrile, butadiene styrene, rubber compound, etc., suitable for tire, rubber hose, adhesive tape, oil seal, auto parts and other rubber products.
Application characteristics: the nano calcium carbonate after surface modification has good compatibility with rubber. It has the properties of reinforcing, filling, color adjusting, improving the processing and product. It can make the rubber easy to mix and disperse. The rubber is soft after mixing and the rubber surface is smooth. The elongation, tensile strength and tearing strength of the products can be made. And so on, which can raise the market competitiveness of the products.
