UV air disinfection

To achieve the activation of bacteria in the air, the closer the ultraviolet lamp tube is from the disinfected object, the faster and faster the bacteria kill. The scope of ultraviolet radiation can ensure that the mortality rate of bacteria is 100 %, and no bacteria escape.
Its bactericidal principle is through ultraviolet rays of microorganisms such as bacteria and viruses to destroy the structure of the DNA (deodorized nucleic acid) in its body, so that it will immediately die or lose the reproductive ability. Quartz UV lamps have advantages, so how to identify authenticity. The ultraviolet sterilization capacity of different bands is different. Only short-wave ultraviolet (200-300nm) can have the ability to kill bacteria. Among them, the cost and performance of ultraviolet lights manufactured in different materials in 250-270nm are also the strongest. A really high -intensity, long -lived ultraviolet light must be made of quartz glass. This kind of lamp is also called quartz sterilization lamp. It is divided into two types: high ozone type and low -disinfection type. The disinfection cabinet is generally high ozone type. This is also this is also the A significant feature of quartz ultraviolet lights relative to other ultraviolet lights. In addition, it produces high ultraviolet intensity, which is more than 1.5 times that of high boron lamps, and has a long life of ultraviolet radiation. The most reliable way to distinguish is to measure the UV -ray degree 254 NM probe. The same power, 254 NM’s ultraviolet intensity is the quartz ultraviolet light. Followed by high-boron glass ultraviolet lights, high-boron glass light UV light strength is easy to decay. After hundreds of hours of lighting, its ultraviolet light intensity drops sharply, down to 50%-70%at the beginning. In the hands of the user, although the lamp tube is still bright, it may no longer work. The degree of light attenuation of quartz glass is far less than high boron lamps. The light pipe with fluorescent powder, no matter what kind of glass manufacturing is made, it is impossible to emit short -wave ultraviolet rays, and it is impossible to produce ozone, because the spectrum emitted by fluorescent powder is the shortest wavelength near 300 nm, in the disinfection \ cabinet cabinet What can be seen often is mosquito -extinguishing lamps, which can only produce 365nm spectrum and some blue light. Its function is not except to attract mosquitoes.
