UV sterilization air purification and disinfection is also used forced indoor air flow pattern of the air through direct exposure to the body's air disinfecting machines, equipped with ultraviolet light disinfection of isolation container, to kill all kinds of bacteria in indoor air, viruses and fungi purpose. Used to kill bacteria, viruses and fungi dose of ultraviolet light disinfection should reach 20000μW.s / cm2 or more. When the microorganisms absorb C-band ultraviolet light, causing photochemical reactions in the microbial cells, the nucleus of DNA (deoxyribonucleic acid) will be destroyed, the cell death or immediate loss of reproductive ability (inactivated virus). But the disadvantage is that ultraviolet light is not directly irradiated human Doing so can cause damage to the human body (such as rashes or conjunctivitis). Therefore, the use of ultraviolet light to disinfect indoor air when, in the absence of state must be used, and need prolonged exposure (over 4-6 hours), but also because of long-term exposure according to the material easy to aging color other than glass, stainless steel and ceramics yellowing. And Wei developed a semiconductor air disinfecting machines can completely avoid these problems, the perfect realization of disinfection and purification, detailed picture phone call. Operating room air disinfection machine, V1 / Wei a (online consultation), Guangzhou air disinfecting machines provided by the Dongguan City-an Environmental Technology Limited.
