Application of Calcium Carbonate in Plastic Industry and Coating Industry
Calcium Carbonate (including heavy calcium and light calcium) is the most widely used inorganic mineral powder material. As a commonly used powder material for plastics, Calcium Carbonate has many advantages that other powder materials do not have, such as high whiteness, Easy surface organic treatment, light wear on processing equipment and molds, good molding processing fluidity, etc., coupled with abundant resources and low price, it has become the preferred inorganic mineral powder material in the plastics processing industry.
Heavy Calcium Carbonate (commonly known as heavy calcium) is the world's first filler in the coatings industry. It is not only cheap, but can greatly reduce the production cost of coatings. As one of the functional fillers, it can affect many properties of coatings, such as changing coatings. Improve the mechanical strength of the film, improve the water resistance and powder resistance of the coating film, etc. It is precisely because it is a high-quality and cheap functional filler that Calcium Carbonate has always been one of the most important basic substances in the composition of paints in civil and industrial paints.
