Light calcium carbonate is an important inorganic chemical product as a filler and reinforcing agent. It is widely used in the production, processing and in application, its molecular structure is CaCO3, a non-toxic, odorless white light powder, with a mass fraction of 0.98-98.5 or more, and the particle shape is spindle, rod, or cubic crystal, etc. The average particle size is 0.5-5 microns, and it absorbs oil. The value is 5.5ml/g, the relative density is 2.4-2.7, it is slightly alkaline, insoluble in water, easy to absorb moisture, and chemically stable.

1. Light calcium carbonate is widely used in rubber products, such as tires, conveyor belt hoses, tapes and medical rubber products, which can reduce the amount of rubber and reduce costs. It can also play a role of reinforcement and semi-reinforcement. The application of light calcium carbonate in plastics can reduce the amount of organic raw materials, reduce costs, improve the stability, hardness and rigidity of the plastic, improve the processing performance of the plastic, increase the heat resistance and improve the astigmatism of the plastic.

2. Light calcium carbonate can play a role in the framework of plastic products, which has a great effect on the dimensional stability of plastic products, can increase the hardness of the products, and can also improve the surface gloss and surface smoothness of the products. The heat resistance of calcium carbonate can be improved by adding calcium carbonate to general plastic products. As the whiteness of calcium carbonate is above 90%, it can also replace expensive white pigments to play a certain role in whitening.

3. Light calcium carbonate is the largest mineral filler in the coating industry, mainly used in automotive coatings, powder coatings, and architectural latex coatings. The gloss, brightness, chemical resistance of the coating can be increased, the rheology can be improved, and the cost can be greatly reduced. For example, the amount of water-based paint can reach 20% to 60%.

4. The application of light calcium carbonate in papermaking can improve the whiteness and glossiness of paper products, and its high expansibility can enable paper mills to reduce the amount of pulp and greatly reduce costs.

5. Light calcium carbonate is used as a friction agent in toothpaste, because it can not only remove dental plaque, material residues, polish the teeth without damaging the enamel, and has good aroma permeability and paste diffusion; in addition, it is micro Alkalinity can neutralize the acidic metabolites of plaque bacteria such as citric acid and lower the pH of the oral cavity. It has multiple functions such as removing acidic plaque and neutralizing acidic metabolites in the oral cavity. Used as a neutralizer, filter aid, buffer and dissolving agent in pharmaceutical formulations, as well as fillers and calcium source supplements. Used as a bulking agent, leavening agent and nutritional supplement in food processing.
