Nano-copper oxide antibacterial agent Compared with the conventional organic fungicide, the nano-copper oxide antibacterial agent produced by Daxine has high temperature and safety, and has long-term bactericidal action against bacteria and mold in a broad spectrum. The nano-copper oxide antibacterial agent is made of a material with stable physical and chemical properties, so the function of the nano-copper oxide antibacterial agent is not damaged by processing, and the nano-copper oxide antibacterial agent not only initially solves the problem that the imported inorganic antibacterial agent is added to plastic and fiber. The phenomenon of discoloration and rapid migration occurs in the middle, and the particle size distribution of the nano-copper oxide antibacterial agent is uniform and ultra-fine, and can be applied to special occasions such as film and microfiber. The nano-copper oxide antibacterial agent is urgent in the market, and New antibacterial materials with broad prospects.
Nano copper oxide antibacterial agent sterilization mechanism
Many metal ions have a bactericidal and antifungal effect. The metal ion bactericidal activity is decremented in the following order:
Ag>Hg>Cu>Cd>Cr>Ni>Pb>Co>Zn>Fe
Since Hg, Cd, Pb, and Cr are highly toxic, metals actually used as inorganic bactericides are mainly Ag, Cu, and Zn. Cu has many times more bactericidal ability than Zn and is safer than Ag.
