Note: according to user requirements of nano particle can provide different size products. Product performance Nano zinc oxide is a new kind of multi-functional inorganic material with particle size ranging from 1 to 100 nm. Due to the fineness of grain, the surface electronic structure and crystal structure change, resulting in the surface effect, volume effect, quantum size effect, macroscopic tunneling effect, high transparency, high dispersion and other characteristics that macroscopic objects do not have. In recent years, it has been found that it exhibits many special functions in catalysis, optics, magnetism, mechanics and so on, which makes it have important application value in many fields such as ceramics, chemical industry, electronics, optics, biology and so on. Nano-zinc oxide can be used as uv shielding material, antibacterial agent, fluorescent material and photocatalytic material in textile, coating and other fields. Nano-zinc oxide has become the focus of many scientists because of its excellent properties and attractive application prospect. Antibacterial Application Nano-zinc oxide has a strong inhibitory effect on escherichia coli and staphylococcus aureus, and can inhibit the growth of prokaryotic cells, eukaryotic cells and escherichia coli in vitro. Moreover, with the increase of zinc oxide content, its antibacterial ability is improved, and the action time between nano-zinc oxide and bacteria also affects the bactericidal ability. Under the condition of light, nano-zinc oxide has more obvious bacteriostatic effect, nano-zinc oxide also has inhibitory effect on other bacteria, and basically no toxic side effect, can be used as preservative, conditioner, etc. Storage conditions This product should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation. | ||||||||||||||||||||
