What is the function of heavy calcium carbonate?

　　At present, heavy calcium is widely used in PVC, PE, PP and various unsaturated resins. Among them, PVC products are a big market for calcium carbonate. For example, they account for 20% - 50% of flexible polyethylene wire, PVC, PVC tile and calcium plastic materials, 10% - 30% of polyethylene and polypropylene packaging materials, and 20% - 60% of auto parts and ceiling. So, what is the specific function of heavy calcium carbonate? Let's have a detailed understanding with Xiaobian!

　　The application of calcium carbonate in the production of paints and coatings is another important use of calcium carbonate. Calcium carbonate is an important filler in coating production. The transparency of the paint is determined by fineness and particle distribution. In addition, calcium carbonate has good weather resistance, wear resistance, low electrolyte content and pH stability effect, which can improve the corrosion resistance and rheological properties of the coating. Calcium carbonate is also very important in water-based coatings, which can improve the quick drying performance and is of great significance in highway marking. In addition, the use of calcium carbonate in coatings can reduce the amount of titanium dioxide, which is beneficial from the economic point of view, which will further increase the amount of calcium carbonate in paint and coating.
