Application
In the papermaking process, adding calcium carbonate can increase the opacity and whiteness of paper, improve the smoothness and printability of paper, and make paper have better writing and printing effects. At the same time, it can also reduce the production cost of paper and improve the physical strength of paper, such as tensile strength and folding resistance.
Calcium carbonate is widely used in rubber. It can increase the volume of rubber and reduce the cost of rubber products. At the same time, it can also improve the processing performance of rubber, such as improving the mixing efficiency of rubber and reducing the viscosity of rubber compound, making rubber products easier to be formed and processed.
As a filler added to plastics, it can reduce the production cost of plastics. At the same time, it can also improve the performance of plastics, such as increasing the rigidity, hardness and dimensional stability of plastics, reducing the shrinkage and deformation of plastics during use. It is widely used in the production of various plastic products such as polyethylene and polypropylene.
