What is the type of air disinfection machine, and what is the classification of the air disinfection machine?
1. Chemistry
It contains pure chemical sterilization and disinfection substances such as alcohol, sodium hypochlorite (84 disinfectant), hydrogen peroxide (hydrogen peroxide disinfectant), sprayed out to disinfect and sterilize the air.
2. High voltage discharge type
The high-voltage discharge ozone disinfection machine uses a high-voltage current of a certain frequency to create a high-voltage corona electric field, which makes the oxygen molecules in or around the electric field electrochemically react to produce ozone. This kind of ozone disinfection machine has the advantages of mature technology, stable work, long service life, large ozone output (single machine can reach 1Kg/h), so it is the most widely used ozone disinfection machine in related industries at home and abroad.

3. Electrolytic
Electrolytic ozone disinfection machines usually generate ozone by electrolyzing pure water. The generator can produce high-concentration ozone water, has low manufacturing cost, and is simple to use and maintain. However, due to the disadvantages that the ozone output cannot be increased, the electrode life is short, and the ozone is not easy to collect, the scope of its use is limited. At present, this kind of generator is only used in some specific small equipment or in some specific places, and does not have the conditions to replace the high-voltage discharge generator.

4. Ultraviolet type
Ultraviolet rays refer to solar rays with wavelengths between 200nm and 380nm, including three types: UV-A wavelengths are 315nm-380nm, UV-B wavelengths are 280nm-315nm, and UV-C wavelengths are 200nm-280nm. The ultraviolet rays (290nm-2000nm) that reach the surface of the earth account for about 13% of the ultraviolet rays, of which UV-A accounts for 97%, UV-B accounts for 3%, and UV-C is close to 0, but UV-C has the best sterilization effect. , The UVC currently used on the market must be a UV-C ultraviolet lamp made by a special process for disinfection and sterilization.
