Application of nano-calcium carbonate in various fields
Nano-calcium carbonate, as an excellent filler, has the advantages of pure white matter, easy coloring, stable chemical properties, low cost, particle size and particle shape can be controlled, etc., and has been successfully applied in rubber, plastics, coatings, ink, paper and other fields. In view of the superior performance of nano-calcium carbonate, more potential value is also becoming a hot spot of development.
Applications in the rubber industry
Calcium carbonate was first used in the rubber industry and is one of the most used fillers. The rubber industry is also one of the main application markets for nano-calcium carbonate, which can be used in rubber products such as tires, hose, tape, seals, and auto parts.
Nanometer calcium carbonate first has the performance of ordinary calcium carbonate, and because of its ultra-pure, ultra-fine, surface modification characteristics, it has a spatial structure and good dispersion in rubber, which can improve the tensile properties, reinforcing properties and anti-aging properties of the material.
Applications in the plastics industry
At present, the most mature application technology of nano-calcium carbonate industry is the plastic industry, and the demand for calcium carbonate in the plastic industry is very large. Nano-calcium carbonate can be used as modulator, reinforcing agent and semi-reinforcing agent for plastics because of its unique excellent properties.
Nano calcium carbonate particle size is small, good dispersion, can reduce the pores and voids in the plastic, so that the plastic mixing and shrinking more uniform, so it can be filled in polystyrene, polyvinyl chloride, aldehyde, phenol plastics and other polymers, improve the stability of the size of plastic products, hardness and rigidity.
Application in coating industry
It can be used as pigment filler and has the advantages of fine, uniform, high whiteness and good optical properties. In the paint making, the Lide powder with higher density in the formula can be suspended to prevent settlement. After painting, the whiteness of the film increases, the gloss is high, and the hiding power is not reduced, which makes it widely used in the coating industry.
Applications in the paper industry
The paper industry is the most potential application field of calcium carbonate in China. Nano-calcium carbonate can be used as a raw material for coating processed paper, especially for high-grade copper sheet paper. Because of its good dispersion performance, low viscosity, can replace part of the clay, can effectively improve the whiteness and opacity of the paper, improve the smoothness and softness of the paper, improve the absorption of ink, improve the retention rate; Nano-grade calcium carbonate used in high-grade sanitary paper can increase the toughness, water absorption and whiteness of the product, and the use is safer and more hygienic.
Application in ink industry
Nano-calcium carbonate as a filler in resin ink, in addition to the role of general ink filler, compared with traditional ink filler, it also has good stability, high gloss, does not affect the drying performance of printing ink, strong adaptability and other advantages, can replace the higher price of colloidal calcium, in order to improve the gloss and brightness of ink. It can improve the adhesion of the ink, reduce the wear of the ink on the machine, and is suitable for high-speed printing.
