Nano calcium carbonate refers to calcium carbonate products with particle size between 1-100nm, which has surface effect, quantum size effect and macroscopic quantum tunneling effect, which makes it show different physical and chemical properties from ordinary calcium carbonate. aspects of the special features.
1. Application of nano calcium carbonate in rubber industry
The rubber industry is the most important application market for nano calcium carbonate. Nano calcium carbonate is used as a filler in rubber with a large amount. Chain nano-calcium carbonate is the most widely used in rubber products, followed by cubic nano-calcium carbonate.
In the rubber industry, nano calcium carbonate is mainly used in rubber products such as tires. The addition of nano-calcium carbonate to rubber products can significantly improve elongation, tear resistance and compression deformation, and the hardness of the product can be adjusted by increasing or decreasing the amount of calcium carbonate.
2. Application of nano calcium carbonate in plastic products
The application of nano-calcium carbonate in the plastics industry is very mature. Among them, ordinary calcium carbonate plays a filling role, and nano-calcium carbonate is mainly used in high-grade plastic products. Cube-shaped nano-calcium carbonate is the most widely used in plastics, with low oil absorption value, and the average particle size is generally required to be in the range of 0.1-0.5μm.
Modified nano calcium carbonate has outstanding advantages in plastic products: improve the heat resistance, hardness and stiffness of the product, improve its processing performance and smoothness, etc.; can also improve the toughness, transparency, aging resistance, etc. of the film; can also improve plastics physical and mechanical properties.
3. Application of nano calcium carbonate in ink industry
In the ink industry, nano-calcium carbonate has become the most widely used filler material. In the ink industry, modified nano-calcium carbonate needs to be used, and the most widely used is spherical or cubic nano-calcium carbonate.
The application of nano calcium carbonate in ink has outstanding advantages, mainly in: high gloss and good stability. my country’s research on nano-calcium carbonate for ink has made great progress.
4. Application of nano calcium carbonate in adhesive and sealant industry
The market demand for structural adhesives and sealants is increasing, and nano-calcium carbonate mainly plays the role of filling and reinforcement in silicone sealing limbs. The most widely used is the cube-shaped nano-calcium carbonate.
The application of nano-calcium carbonate can greatly reduce the cost, and can improve the processing performance and mechanical properties of the product.
5. Application of nano calcium carbonate in coating industry
Nano calcium carbonate as pigment filling is a very promising market. In coating applications, nano-calcium carbonate is generally required to be cube-shaped or spindle-shaped.
Nano calcium carbonate has many advantages when used in coatings, such as making the coating fine, uniform, and high whiteness, and can also play an anti-settling role. These advantages make nano calcium carbonate widely popularized and used in the coating industry.
6. Application of nano calcium carbonate in paper industry
In the paper industry, nano-calcium carbonate is used as a filler, which has many advantages, such as high light shielding, good brightness and whiteness, and uniform and smooth paper. Nano calcium carbonate can also be used in various advanced packaging papers after special coating treatment.
7. Application of nano calcium carbonate in lubricating oil
Nano calcium carbonate particles are used as lubricant additives, and can form a protective film containing calcium carbonate on the surface during friction. Nano calcium carbonate will not corrode metals or pollute the environment. It can also neutralize the sulfuric acid produced by combustion in the use of heavy oil with high sulfur content, which has a certain cleaning effect.
