Chemical property: Nano meter zinc oxide also has many chemical properties such as anti-bacterial,anti-mildew,specific catalysis and phototalysis etc. Because of those properties,it can be wildly used in development of anti-bacterial product. Applied to the rubber product it has those effectives :fast vulcanization,wild range of reaction temperature,high rate of zinc sulfide conversion. The consumption is only 10-30%of normol zinc oxide. Applied to development of antimicrobial product it has zinc ion and tomic oxygen triple antibacterial function. With broad function of culling bacteria and viruses and its sponge-like porous micro-structure,it has long-term sustained release effect.
