With the continuous development of science and technology, nanotechnology has become one of the important fields in the world today. As one of the important applications of nanotechnology, nano-calcium carbonate has shown a wide range of application prospects in many fields. Nano calcium carbonate is a kind of calcium carbonate particles with nanometer unit size, due to its unique physical and chemical properties, it has a wide range of applications in polymer materials such as plastics, rubber, coatings, inks, adhesives, and sealants. This article will detail the application of nano-calcium carbonate and its role in various fields.
1. Plastics industry.
Nano calcium carbonate is an important filler in the plastics industry, which can improve the mechanical, thermal and processing properties of plastics. By adding nano calcium carbonate, the impact strength, tensile strength and bending strength of the plastic can be significantly improved, and the shrinkage rate and thermal expansion coefficient of the plastic can also be reduced. In addition, nano-calcium carbonate can also improve the flame retardant performance and aging resistance of plastics, making them have a wider range of applications.
2. Rubber industry.
In the rubber industry, nano calcium carbonate is mainly used for the reinforcement and filling of rubber products. By adding nano calcium carbonate, the abrasion resistance, tear strength, tensile strength and other properties of rubber can be improved, and its service life can be prolonged. At the same time, nano calcium carbonate can also improve the processing performance of rubber and improve production efficiency. In tire manufacturing, the application of nano calcium carbonate can improve the anti-wear performance and driving stability of tires, reduce fuel consumption and improve safety.
3. Paint and ink industry.
In the coating and ink industry, nano-calcium carbonate can be used as pigments and fillers to improve the gloss, hiding power, weather resistance and other properties of coatings. Due to the high specific surface area and good dispersibility of nano calcium carbonate, it can be well dispersed in coatings or inks, improving the hardness and scratch resistance of coatings. At the same time, nano calcium carbonate can also improve the shielding performance of the coating against ultraviolet rays and prevent the coating from aging and discoloration.
4. Adhesive and sealant industry.
In the adhesive and sealant industry, nano calcium carbonate can be used as a thickener, reinforcing agent and filler to improve the mechanical properties, weather resistance, and high temperature resistance of adhesives and sealants. By adding nano-calcium carbonate, the adhesion and durability of adhesives and sealants can be improved, so that they can better meet the requirements of various complex environments.
5. Applications in other fields.
In addition to the above fields, nano calcium carbonate is also widely used in papermaking, textiles, cosmetics and other fields. In the paper industry, nano calcium carbonate can be used as a filler to improve the whiteness and opacity of the paper; In the textile industry, nano-calcium carbonate can be used to manufacture functional textiles such as antibacterial and anti-ultraviolet rays; In cosmetics, nano calcium carbonate can be used as a brightener and moisturizer to improve the use effect of cosmetics.
In conclusion, nano-calcium carbonate, as a new material, has a wide range of application prospects. With the continuous development of science and technology, it is believed that more application fields of nano calcium carbonate will be explored in the future. At the same time, with the in-depth research on the performance and application of nano calcium carbonate, its application effect will be continuously improved and improved.
