Kitchens, washrooms, furniture, and invisible corners are often prone to mold growth, which is a problem that every family often encounters. The common cleaning method is to wipe with soapy water, bleach and towel, and keep the environment dry. However, in the damp-prone corners such as toilets and closet closets, mold re-emerges after a while. In such places where mold is prone to repeatedly grow, consider using ultraviolet disinfection lamps to eliminate molds. Why can UVC ultraviolet disinfection lamps lamp be used to kill mold? This article will reveal to you why UVC ultraviolet lamp
s can kill molds at home. The common low-pressure mercury UVC ultraviolet anti-virus lamp is a gas discharge light source. The uv lamp of the gas light source uses a lower mercury vapor pressure (<10-2Pa) to be excited to emit ultraviolet light, which can generate two ultraviolet wavelengths of 253.7nm and 185nm. Short-wave ultraviolet wavelengths are invisible to the naked eye. The short-wave uv lamp with the center wavelength of 253.7nm can play a good sterilization effect. This is mainly because microbial cells can reach the maximum absorption of 250~270nm ultraviolet rays. After absorbing ultraviolet rays, microorganisms such as fungi and viruses act on the genetic material of the cell, which is DNA, causing DNA base pair bond strand breaks and causing genetic material to mutate, causing bacteria to inherit. Substances cannot replicate or reproduce offspring, so as to achieve the purpose of killing germs. The photochemical effect of ultraviolet disinfection lamps on molds. Generally speaking, the ultraviolet dose required to kill different microorganisms is related to the irradiation time and effective radiation intensity of the short-wave ultraviolet disinfection lamps lamps. The choice of UVC uv lamp should be based on the area of u200bu200bthe house. The ultraviolet lamp manufacturer TANK007 tells you that the 15W radiation intensity of general household shortwave ultraviolet lamps is 75μw/cm2. The irradiation time needs to meet 30 minutes to kill common Aspergillus flavus, Aspergillus niger, Rhizopus niger, etc.
