The ultraviolet sterilization band is mainly between 200 and 300nm, and the sterilization ability of 253.7nm is strong. When all kinds of bacterial viruses in water or air pass through the ultraviolet (253.7nm wavelength) irradiation area, ultraviolet rays penetrate the cell membrane and nucleus of microorganisms, destroy the molecular bond of nucleic acid (DNA or RNA), make it lose the ability of replication or activity and die, so as to kill all bacterial viruses without using any chemical drugs.The sterilization lamp does not need to be converted into visible light, and the wavelength of 100-200nm can play a good role in sterilization. This is because there is a rule in the absorption spectrum of the light wave of the cell, which has a large absorption of 100-200nm ultraviolet rays. The absorbed ultraviolet rays actually act on the cell genetic material, namely DNA, which plays a photochemical role. The energy of ultraviolet photons is absorbed by the base pairs in DNA, causing The variation of genetic material causes the bacteria to die or not to reproduce immediately, so as to achieve the goal of sterilization.
Advantages of UV disinfection technology：
The disinfection effect of ultraviolet disinfection technology on bacteria, virus and other pathogenic bodies has been recognized all over the world, and it has the incomparable sterilization efficiency of other technologies. The bactericidal effect of ultraviolet on bacteria and virus is generally within one second. For the traditional chlorine and ozone methods, it usually takes 20 to 50 minutes to achieve the sterilization effect of ultraviolet. It has many advantages, such as high-efficiency sterilization, wide spectrum, no secondary pollution, safe and reasonable design, safe and reliable operation, simple operation and maintenance, low cost, small occupation space, no noise, continuous large number of sterilization, wide application field and so on.
The medical ozone disinfector, which is based on the principle that oxygen in the air is produced by high frequency and high voltage electric shock, has high ozone output, fast sterilization and disinfection speed, no residue and secondary pollution, and low price and operation cost. It is used in the clean environment of food production, hospital, electronic and other industries, which requires aseptic operation, instead of ultraviolet irradiation and chemical fumigation, without residual pollution.
The working principal of ozone:
Ozone is a highly effective disinfectant, which has a strong killing power to bacteria, bacteria, fungi, fungal spores, viruses and other microorganisms. As ozone is a diffuse gas, there is no dead angle in disinfection, so the disinfection and sterilization effect is good. Ozone sterilization is also different from general fungicides, because the excess ozone can be quickly decomposed into oxygen, so there is no secondary pollution problem.
Ozone can effectively remove toxic gases, such as C0, S02, mustard gas, etc. Ozone dissolved in water can be oxidized and decomposed to effectively remove toxic substances in water, such as heavy metal ions, organic poisons, cyanide, sulfide, dichlorvos, Omethoate, marasulfuric acid and other pesticides.
Due to the strong killing effect of ozone on bacteria and microorganisms, the treatment of meat and other foods with ozone water can achieve the effect of antisepsis, odor elimination and fresh-keeping. Studies have shown that ozone can prolong the storage period of food, beverage, fruits and vegetables by 3-10 times.
Ozone can deodorize and remove peculiar smell. The main components causing odor and putrefaction in nature are ammonia, hydrogen sulfide, methylmercaptan, dimethylsulfide, dimethyldisulfide, etc. ozone can react with them to oxidize them into non-toxic and odorless substances, so as to achieve deodorization effect.
