The process of ozone sterilization belongs to biochemical oxidation reaction. There are three principles. One is to oxidize and decompose the enzymes required for the glucose inside the bacteria to inactivate and kill the bacteria; the other is to directly interact with bacteria and viruses to destroy their organelles, DNA and RNA. The metabolism of the bacteria is destroyed, leading to the death of the bacteria; the third is to penetrate the cell membrane tissue, invade the cell, and act on the lipoprotein of the outer membrane and the lipopolysaccharide inside, causing the bacteria to undergo permeability distortion and dissolve and die.
Then why is it said that ozone is a green sterilization and oxidant? This is because at room temperature, ozone will decompose into oxygen by itself in about 30 minutes, so there is no residue and secondary pollution.
In addition, ozone is very easy to dissolve in water, and the ozone concentration in the generated ozone water can kill bacteria when the concentration reaches 0.1-0.2mg/L, and can kill viruses when the concentration reaches 0.4mg/L. The ozone sterilizing washing machines on the market just take advantage of this characteristic of ozone and add an ozone generator inside to form ozone water when the washing machine washes clothes to prevent bacteria and disinfect the clothes. In addition, ozone water can also enhance the decontamination ability of detergents and improve the cleanliness of laundry. Not only that, some ozone sterilization washing machines can also eliminate bacteria without water, that is, use ozone gas to carry out “dry cleaning” type sterilization, disinfection and deodorization of clothes。
