Since the outbreak of the coronavirus, people have paid more and more attention to sterilization. As a tool for sterilization and disinfection, the UV light ultraviolet wands have become an important tool for many people to fight against the coronavirus.
The emission spectrum of the UV light mainly has 254nm and 185nm.
254nm UV light is a non-ozone band, which kills bacteria by irradiating the DNA of microorganisms. 185nm UV light can turn oxygen in the air into ozone.
Ozone-type UV light has advantages and disadvantages. Ozone has a strong oxidizing effect, which can oxidize the cell body of bacteria, destroy its DNA directly and achieve an inhibitory effect. It also has a destructive effect on the RNA of the virus.
The ozone-type UV light has a certain oxidation effect on various toxins, reduces its toxicity, and can kill bacteria effectively. The dispersibility of ozone can make up for the fact that the ultraviolet rays only spread in a straight line, and the disinfection is relatively thorough.
However, excessive ozone is harmful. It stimulates the human respiratory tract,causing sore throat,chest tightness,coughing, bronchitis and emphysema. Therefore, it is necessary to open windows for ventilation.Pay attention to keep rubber products, steel and other items away from it when using it to avoid corrosion.
Ozone-free the UV light also have advantages and disadvantages. Ozone-free the UV light mainly rely on UVC ultraviolet rays to destroy the molecular structure of DNA and RNA in microbial cells, so that they lose their transformation ability, so as to achieve the purpose of sterilization. It is ozone-free, and people can enter the room immediately after sterilization.
But the ultraviolet rays only spread in a straight line, and the disinfection is not thorough. Moreover, ultraviolet rays can react with oxygen to generate ozone. Therefore, the lower the ozone in the ozone-free UV light ultraviolet wands, the better.
