Calcium carbonate has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related products are numerous. The following describes in detail the upstream and downstream associated products of calcium carbonate.
upstream products
1. Limestone: calcium carbonate production is mainly limestone as raw material, obtained through processing and refining. Limestone is a common natural mineral with abundant resources and low price, which provides sufficient raw material guarantee for the production of calcium carbonate.
2. Calcite: Calcite is another common calcium carbonate mineral that can also be used to produce calcium carbonate. Compared with limestone, the purity of calcite is higher, but the resources are relatively few and the price is relatively high.
downstream products
1. Plastic: calcium carbonate can be used as a plastic filler to improve the hardness, rigidity, heat resistance and dimensional stability of the plastic. Common plastic products such as plastic bags, pipes, profiles, etc. may use calcium carbonate as a filler.
2. rubber: calcium carbonate can also be used in rubber products to improve the wear resistance, tear resistance and heat resistance of rubber. Automobile tires, rubber hose, tape and other rubber products may use calcium carbonate as a filler.
3. coating: calcium carbonate can be used as a filler of coating to improve the hiding power, leveling and weather resistance of the coating. Architectural coatings, automotive coatings, wood coatings and other coating products may use calcium carbonate as a filler.
4. Papermaking: Calcium carbonate can be used in the paper industry as a filler and coating agent for paper to improve the whiteness, opacity and printing performance of paper. Calcium carbonate may be used as a filler in paper such as cultural paper and wrapping paper.
5. Food: Calcium carbonate can be used as a food additive to supplement calcium in food and improve the nutritional value of food. Common calcium-containing foods such as calcium tablets, dairy products, soy products, etc. may use calcium carbonate as an additive.
In short, calcium carbonate is widely used in the field of chemical production raw materials, and its upstream and downstream related products are numerous, involving plastics, rubber, coatings, papermaking, food and other fields.
