Ultraviolet air sterilizer is a disinfection equipment, through which can help the air, ultraviolet light and other sterilization, to help remove the harmful components of the air, to avoid too much indoor air toxic gases, affecting the daily use of people. With the increasing environmental pollution, air pollution problems, the use of ultraviolet air sterilizer more and more cases, ultraviolet air sterilizer in the family, schools, companies and other indoor places can be used. So, what is the principle of UV air sterilizer?
Ultraviolet air sanitizer principle
Ultraviolet light is a kind of invisible light waves, exists in the spectrum of violet ray end of the outer, so called ultraviolet. Ultraviolet radiation from the sun is one of the electromagnetic waves, usually in accordance with the wavelength of the ultraviolet radiation is divided into four categories as follows
is a special form of material operation, is a particle of the particle stream is not connected. Each UV photon with a wavelength of 253.7nm has an energy of 4.9eV. When the ultraviolet light irradiation to microorganisms, the transfer and accumulation of energy occurs, the accumulation results in the inactivation of microorganisms, so as to achieve the purpose of disinfection. When bacteria and viruses absorb more than 3600~65000uW/c㎡dose, it has strong destructive power to the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) of the bacteria and viruses, which can make the bacteria and viruses lose their viability and reproducibility and then destroy the bacteria and viruses, thus achieving the effect of disinfecting and sterilizing. On the one hand, UV rays can make nucleic acids mutate, hinder their replication, transcription blockade and protein synthesis; on the other hand, the generation of free radicals can cause photoelectric ionization, thus leading to cell death.
Ultraviolet sterilizer sterilization principle is the use of ultraviolet lamp irradiation intensity, i.e., ultraviolet germicidal lamps issued by the irradiation intensity, and the distance from the illuminated disinfectant inversely proportional. When the irradiation intensity is certain, the longer the illuminated disinfectant stays, the closer the germicidal lamp is, the better the sterilization effect, and vice versa.
Ultraviolet Air Sterilizer Usage
1, household ultraviolet sterilizer disinfection lamp for air disinfection should be closed windows and doors, since the lamp is bright?5-7?minutes after the timing of each disinfection time shall not be less than 60?minutes, ultraviolet sterilizer lamp irradiation process is prohibited to enter the indoor, must enter, should be stopped first! UV disinfection lamp irradiation, especially young unmarried women should bear in mind this.
2, with the household ultraviolet sterilizer disinfection lamp disinfection items, the items will be spread out or hung up to expand the irradiation surface, the effective distance of one meter, irradiation can be about 30 minutes.
3, the use of household ultraviolet sterilizer disinfection lamps, should keep the environment clean, the air can not have dust and water spray, etc., when the indoor temperature is lower than 20 degrees Celsius or relative humidity more than ?50%, the irradiation time should be extended. After scrubbing the ground to be dry before the ground UV lamp disinfection.
4, household ultraviolet sterilizer disinfection lamp lamp surface should be kept clean, no dust, weekly wipe with ?95% ethanol cotton balls, and it is best to keep good records.
5, ultraviolet light on the human skin mucous membranes have some damage, the use of household ultraviolet sterilizer disinfection lamps should pay attention to good protection, the eyes absolutely can not look directly at the ultraviolet light source, otherwise the eyes will be injured.
6, to household ultraviolet sterilizer disinfection lamp to establish the use of time record book, every irradiation record, because the ultraviolet disinfection lamp lamp service life of 1000 hours. In addition, it is necessary to regularly use the ultraviolet intensity indicator card on the ultraviolet disinfection lamp ultraviolet intensity testing.
Principle and use of ultraviolet air sterilizer is also introduced for everyone clear, ultraviolet air sterilizer is a very good disinfection equipment, through the help of the ultraviolet air sterilizer can be brought to their own safer environment, to improve the air in the toxic gases and so on. In order to ensure that the ultraviolet air sterilizer function completely out, remember to be able to follow the relevant operation to the correct use, will not be used indiscriminately and miss the best results of the ultraviolet air sterilizer.
