The use method and precautions of the uv lamp The uv lamp uses ultraviolet rays to kill bacteria, including bacterial propagules, spores, mycobacteria, coronaviruses, fungi, rickettsia and chlamydia, etc. All surfaces contaminated by the above viruses, Both water and air can be disinfected with ultraviolet rays. The precautions for use are as follows: 1. The hanging height of the ultraviolet lamp
. It should be hung vertically, 2-2.5 meters above the ground. 2. The range of the ultraviolet lamp is used. The line emitted from the inner surface of the germicidal ultraviolet lamp is c-wave, and its wavelength range is 200-270nm, and the central wavelength of sterilization is 253.7nm. In the case of sufficient ultraviolet intensity and irradiation time, all microorganisms can be killed. However, the penetration power of ultraviolet rays is extremely weak, and its irradiation intensity is inversely proportional to the square of the distance, and it can only play a bactericidal effect on the irradiated surface. At present, the types currently produced in our country mainly include these types: the power is 15w, 20w, 30w, and 40w. At present, we use the most 30w ultraviolet lamps, and the requirement is 1.5w per cubic meter of area. 3. The cumulative time of each UV lamp tube is 1000 hours. If it exceeds 1000 hours, it should be replaced with a new one in time. New replacements should indicate the replacement time and re-accumulate the use time. 4. During the use of the UV lamp, the surface of the UV lamp should be kept clean. Generally, try it with an alcohol cotton ball once every two weeks. If there is a gray layer or oil stain on the surface of the lamp tube, it should be tested at any time. 5. uv disinfection lamp
has a sterilization efficiency unmatched by other technologies. The sterilization efficiency can reach 99%-99.9%. Traditional chemical disinfection methods such as chlorine and ozone generally require 30 minutes to 1 hour to achieve the UV C sterilization effect. After disinfection, you must remember to open the window for more than 30 minutes to ventilate, otherwise it will be harmful to health.
However, with the increased prevalence of uv sterilizer
aquarium, it has become far more affordable.
