Is heavy calcium powder the same as light calcium powder?
Heavy calcium carbonate, referred to as heavy calcium powder, is a white powder processed from high-quality calcite. Its main component is CaCO3, which has the characteristics of high whiteness, good purity, soft color tone and stable chemical composition. Light calcium carbonate powder is light calcium carbonate powder, also called precipitated calcium carbonate, referred to as light calcium carbonate. It is made by burning limestone and other raw materials to generate lime and carbon dioxide, adding water to digest lime to generate lime milk (mainly calcium hydroxide), and introducing carbon dioxide to carbonize the lime milk to generate calcium carbonate precipitation. After dehydration, drying and crushing, the light calcium carbonate powder has smaller particle size, higher oil absorption and higher price. They are commonly used fillers in latex paints, and it is best to use them together. Light calcium has good sedimentation, but its oil absorption is greater than that of heavy calcium, and its price is generally more expensive than that of heavy calcium. Although the stability is not as good as that of heavy calcium, it is still stable. Even in exterior wall coatings, its application is very great! Heavy calcium powder is usually used as a filler, which is widely used in artificial floor tiles, rubber, plastics, paper making, coatings, paints, inks, cables, building supplies, food, medicine, textiles, feed, toothpaste and other daily chemical industries. As a filler, it can increase the product volume and reduce the production cost.
