Nanomaterials are materials that have at least one dimension in the range of 0.1-100 nm in three-dimensional space, or are composed of such materials as basic units. Due to the surface and interface effects, size effects, quantum size effects, and macroscopic quantum tunneling effects of nanomaterials, they have good applications in various fields. Modifying some basic materials using nanotechnology may produce unexpected changes.

Nanomaterials and New Materials

　　Nanomaterials refer to materials with at least one dimension in the range of 0.1～100nm in three-dimensional space, or materials composed of them as basic units. Due to the surface and interface effects, size effects, quantum size effects, and macroscopic quantum tunneling effects of nanomaterials, nanomaterials have good applications in various fields. Modifying some basic materials using nanotechnology may produce unexpected changes.

　　What is Guangxi Longhua nano calcium carbonate?

　　Guangxi Longhua nano calcium carbonate has a particle size between 1～100nm, including ultrafine calcium carbonate (particle size 20～100nm) and ultrafine calcium carbonate (particle size 1～20nm). Compared with ordinary calcium carbonate, nano calcium carbonate shows obvious advantages in reinforcement, dispersibility, heat resistance, and dimensional stability, making it one of the most widely used nano-filling materials. Therefore, the preparation, modification, and industrial application of nano calcium carbonate are receiving increasing attention from the industry.

　　Applications of Guangxi Longhua nano calcium carbonate

　　As a nano-level filler modifier, Guangxi Longhua nano calcium carbonate has a wide range of applications. Xiangfa Powder, a manufacturer of Guangxi Longhua calcium carbonate, will briefly list some of the main application areas of Guangdong nano calcium carbonate.

　　Plastics Industry

　　The plastics industry is currently the largest consumer of nano calcium carbonate in the world. It can act as a regulator and enhancer for plastics, with a huge demand. Due to its good dispersibility, nano calcium carbonate can effectively remove voids and bubbles in plastics, allowing for more uniform shrinkage and improving the mechanical properties and thermal stability of plastics.

　　

　　After adding modified nano calcium carbonate to PVC film materials, tests show that the tensile strength and impact strength of this composite material have been significantly improved. In addition, experiments have also proved that the addition of nano calcium carbonate can effectively improve the anti-aging properties of PVC film materials.

　　Rubber Industry

　　The use of Guangxi Longhua nano calcium carbonate in rubber can improve the toughness, tensile strength, and durability of rubber products. It can not only be used alone as an excellent functional material, but can also be mixed with fillers such as titanium dioxide and white carbon black to reduce the percentage of rubber base in rubber products or replace some relatively expensive white fillers, while improving the performance of rubber products.

　　

　　Researchers have prepared nano calcium carbonate/natural rubber composite materials. Tests have shown that the addition of nano calcium carbonate improves the tensile strength and quantitative elongation stress of natural rubber.

　　Papermaking Industry

　　The development and use of Guangxi Longhua nano calcium carbonate in the paper industry can improve the whiteness and opacity of paper, reduce the proportion of pulp in paper products, and greatly reduce the cost of paper production. At the same time, due to the addition of nanoparticles, paper products are smoother and more uniform.

　　

　　Relevant scientists have applied starch-modified nano calcium carbonate to the paper industry, increasing the smoothness of the paper and improving the proportion of fillers in the paper, greatly reducing the cost of paper production.

　　Coatings Industry

　　The film-forming materials, fillers, and other auxiliaries in coatings contain many reaction sites, which will interact with the reaction sites on the surface of Guangdong nano calcium carbonate particles, forming a stable and dense bonding layer, thereby enhancing the coating performance of the coating.

　　

　　Foreign scientists have added modified Guangdong nano calcium carbonate to polyester/epoxy mixtures to obtain powder coatings with high hardness and strong adhesion.

　　Nanomaterials Have a Bright Future

　　In recent years, nanomaterials have been widely used in people's production and life. Due to their excellent application performance brought about by their unique nano-characteristics, they have attracted widespread attention from researchers. Nano calcium carbonate, as a representative of nanomaterials, its filling performance has gradually been developed and applied to various manufacturing industries. It is expected that the demand for nano calcium carbonate will continue to rise in the next few years, with good market prospects. At the same time, due to technological development and rising living standards, the nano calcium carbonate industry is gradually upgrading, and the technology is constantly improving. Nano calcium carbonate will inevitably be applied to more emerging industries, with very broad application prospects.
