Spherical nano-silica as a versatile active ingredient, can be tailored for different industries. Xinlei spherical nano-silica powder will make the most of our clients greatly benefit from, with many targeted silica products, but also according to customer's need to provide unique and innovative products and provide technical services. Antibacterial Properties of nanomaterials found that the addition of nano silica more than 0.5%, the sample to show significant antibacterial effects. Spherical nano-silica as the carrier of nanometer silver antibacterial materials, fine chemical raw materials has been successfully applied anti-bacterial mold. Nano-antibacterial agent (the oxidation of silicon as the carrier to Ag + as the main antibacterial ingredient) in powder coatings: powder coatings in general about 2% of added nano-antibacterial agent, the coating's antibacterial effect has been markedly improved, paste membrane of E. coli testing and Staphylococcus aureus on the bactericidal rate of greater than 99% (37 ℃, 23h). The nano-silica, titanium dioxide, zinc oxide nano-materials such as latex paint modified with nano-composite can effectively kill E. coli, Staphylococcus aureus, a series of bacteria, including E. coli can kill rate of about 3h more than 99%, and the inhibitory effect of very durable
