Product Introduction
Light calcium carbonate is a common compound whose chemical formula is. It is a white powder, tasteless, odorless, with high stability and chemical inertness. It is widely found in marble, coral, shells, limestone and other biological and non-biological substances in nature. It is also a compound widely used in human life, and its application field is very wide.
Light calcium carbonate has a wide range of applications in production, such as building materials, papermaking, plastics, coatings, rubber, ceramics, medicine, food, etc. Among them, in terms of building materials, calcium carbonate is often used to make limestone, which is a common building material, which is widely used in the construction and repair of housing construction and other building structures. In the paper industry, calcium carbonate is used as a filler and coating to improve paper quality and reduce production costs. In the plastics industry, calcium carbonate is used as a reinforcing agent to increase the hardness and strength of plastics. In the food industry, calcium carbonate is used as an acidity regulator and as an ingredient in chewable capsules. In addition, calcium carbonate is also widely used in the pharmaceutical industry to make calcium tablets, stomach medicine and oral liquid and other products.
