At present, the vigorous development of the heavy calcium industry is mainly due to the continuous and substantial increase in the use of heavy calcium in the paper industry, and the rapid development of the plastics industry, rubber industry, coatings industry, and building materials.
Heavy calcium carbonate is mainly used as a filler in papermaking, plastics, rubber, coatings, sealants and other industries. In recent years, with the rapid development of these industries, the demand for heavy calcium is also increasing, and the paper and plastic industries will play a leading role in the growth of calcium carbonate demand.
Heavy calcium has a very important role in the paper industry, which can ensure the strength and whiteness of the paper, and the cost is low. The improvement of the performance of heavy calcium carbonate on paper is mainly reflected in the following aspects: improving opacity and brightness; improving smoothness and uniformity and softness; reducing hygroscopicity and deformation; enhancing ink absorption and printability; reducing paper cost.
Adding heavy calcium can improve some properties of plastic products and expand its application range. The role of adding heavy calcium in plastic products is to improve the dimensional stability of plastic products; improve the hardness and rigidity of plastic products; improve the processing performance of plastics and improve The surface gloss and surface flatness of products; improve the heat resistance of plastic products; improve the astigmatism type of plastics; make plastic products have certain properties, such as insulation, plating performance, printing performance.
Calcium carbonate is the most widely used physical pigment in coatings. It plays the role of filling the skeleton and substrate in the paint film. It mainly replaces TiO2 and other pigments in the coating, reduces the production cost of the coating, and can improve the water resistance and mechanical properties of the coating. Strength to improve its gloss.
Heavy calcium is one of the most important fillers in the rubber industry. It can increase the capacity of rubber products and sometimes has the functions of reinforcement, isolation, release, and coloring, which can reduce costs. Filling rubber with heavy calcium can obtain higher tear strength and abrasion resistance than pure rubber vulcanizates. As a filler, heavy calcium is suitable for manufacturing heels, soles, floors, hoses, foamed products, molded products, and extruded products.
