Main applications and market prospects of nano calcium carbonate
The particle size of nano calcium carbonate is 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 has 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 have also attracted more and more attention in the industry.
As a nano-scale filling modifier, nano-calcium carbonate has a very broad application prospect.
Plastic industry
The plastics industry is currently the industry that uses the most nano-calcium carbonate in the world. It can act as a regulator and enhancer for plastics, and the demand is very large. Due to the good dispersibility of nano-calcium carbonate, the voids and air bubbles in the plastic can be well removed, so that the plastic can shrink more uniformly and improve the mechanical properties and thermal stability of the plastic.
Rubber industry
The use of nano-calcium carbonate in rubber can improve the toughness, tensile resistance and resistance of rubber products. It can not only be used as an excellent functional material alone, but also can be mixed with filler materials such as titanium dioxide and silica to reduce the percentage of gum base in rubber products or replace some relatively expensive white fillers. At the same time, it can achieve the purpose of improving the performance of rubber products.
Paper industry
The development and use of nano-calcium carbonate in the paper industry can improve the whiteness and shading of paper, reduce the ratio of pulp in paper products, and greatly reduce the cost of paper production. At the same time, due to the addition of nanoparticles, the paper product is more flat and uniform.
Paint industry
The film-forming binders, fillers and other auxiliaries in the coating contain many reactive sites, which will interact with the reactive sites on the surface of the nano-calcium carbonate particles to form a stable and dense bonding layer, making the coating material. enhanced film performance.
In recent years, nanomaterials have widely appeared in people’s production and life. Due to their excellent application performance brought about by their unique nanometer characteristics, they have attracted extensive attention of researchers. As a representative of nanomaterials, nano-calcium carbonate has been gradually developed and applied in various manufacturing industries with its filling properties. It is expected that the demand for nano-calcium carbonate will continue to rise in the next few years, and there will be a better market prospect. At the same time, due to the development of science and technology and the rise of living standards, the nano-calcium carbonate industry has been gradually upgraded and the process has been continuously improved. Nano-calcium carbonate will also be used in more emerging industries and has a very broad application prospect.
