Silica factory can produce many types of silica. Nano-silica is an important member of nano-materials, it's amorphous white powder, non-toxic, tasteless, non-polluting non-metallic materials. Microstructure was flocculent and reticular quasi-granular structure, spherical. This particular structure makes it unique in nature:
Nano-silica on the wavelength of 490 nm within the UV reflectivity as high as 70% to 80%, add it in the polymer material, can achieve the purpose of anti-ultraviolet aging and thermal aging.
The small size effect and macroscopic quantum tunneling effect of nano-silica make it have the effect of siltation, which can penetrate into the vicinity of the unsaturated bond of the polymer chain and react with the electron cloud of the unsaturated bond to improve the heat of the polymer material, light stability and chemical stability, thereby enhancing the product's anti-aging and chemical resistance.
Nano-silica at high temperature still has the characteristics of strength, toughness and stability, it is dispersed in the material, combined with the polymer chain to form a three-dimensional network structure, thereby enhancing the material strength, flexibility and other basic properties.
Nano-silica has three-dimensional silica structure, large specific surface area, unsaturated coordination number, so that the pigment ion has a strong adsorption, can reduce the UV radiation caused by the attenuation of the pigment.
The silica factory which can produce nano-silica needs to have modern standard factory buildings, complete sets of advanced production equipment and sophisticated detection equipment, and should pay attention to environmental protection.
