Calcium carbonate (CaCO3) is an inorganic compound commonly known as greystone, limestone, stone powder, marble, etc. Calcium carbonate is neutral, slightly soluble in water, soluble in hydrochloric acid. It is one of the common substances on the earth, present in aragonite, calcite, chalk, limestone, marble, travertine and other rocks, and is also the main component of animal bones or shells. Calcium carbonate is also an important building material and is widely used in industry
In the plastics industry, calcium carbonate is used as a filler and modifier, which can reduce the production cost of plastics and improve production efficiency. It can improve the stability of plastic products, such as adding calcium carbonate to polyvinyl chloride (PVC), polyethylene (PE) and polypropylene (PP) and other plastics, which can improve its processing properties, wear resistance, tensile strength, impact strength, bending strength, elongation at break and thermal properties of products.
In the construction industry, it is used as a raw material for cement. It can improve the compressive strength, flexural strength and durability of cement, improve the construction performance of cement, and improve the seismic performance of buildings. In ceramic and glass manufacturing, the hardness, wear resistance, corrosion resistance and transparency of the material can be improved.
In agriculture, it is used as a fertilizer additive and an improver. It can improve the disease resistance of crops, promote root growth and soil acid-base balance, and thus improve the yield and quality of crops. In the medical field, it is used as a drug carrier and additive. It can improve the stability and efficacy of the drug and reduce the adverse reactions of the drug. It can also be used to treat excessive stomach acid and prevent stones. In the field of environmental protection, calcium carbonate is used as an adsorbent and precipitator. It can remove harmful substances in the water, reduce the hardness of the water body, and improve the water quality. Calcium carbonate can also be used in fields such as waste gas treatment and soil remediation.
In the cosmetics industry, it is used as an additive in beauty products. It can improve skin texture, increase skin elasticity, and make skin smoother and more delicate. It can also be used to make toothpaste, shampoo and other products. In the production of coatings and paints, it is an important filler that can improve the weather resistance of coatings, wear resistance, low electrolyte content, PH stabilization effect, corrosion resistance and rheology of coatings.
In the food industry, calcium carbonate can be used as a food additive, such as in food coloring, medicine, binder and hygiene products.
