Zinc oxide particle size in between 20-100nm, due to sharp increase in surface area, making a fundamental precursor Zinc oxide bulk materials, surface effects do not have the small size effect and the macro-quantum tunnel effect. Therefore magnetic, light, electricity, sensitive zinc oxide has the general product unmatched performance and new uses for the special.
      Zinc oxide itself is white and yellowish, shading can be simple, cheap, and other nano-materials with a shielding ultraviolet, infrared absorption and the role of bactericidal mold. Zinc oxide also has a thickening effect, contribute to the stability of pigment dispersion. ZnO in the sun, especially in the ultraviolet radiation, in water and air (oxygen), you can activate the oxygen in the air to active oxygen, a very strong chemical activity. Add Zinc oxide, therefore the car glass and architectural glass can be UV, wear-resistant, anti-bacterial and deodorant.
