Modern people pay more attention to their own health. Bacteria linger around us all the time. Many people buy ultraviolet disinfection lamps at home for the health of children or the elderly for disinfection. But at the same time, most people have doubts that UV disinfection lamps can eliminate them. Are bacteria harmful to the human body? What are the precautions when using it? Today I will answer these questions for everyone.Read More
Ultraviolet ray sterilization is one of the most effective modern sterilization technologies. Its working principle is mainly to destroy the DNA of microorganisms, so that the microorganisms lose the function of reproduction and replication, so as to achieve the effect of sterilization.
Ultraviolet rays are harmful to the human body. If human skin and eyes are exposed to ultraviolet light for more than 3 minutes, it will reach the safety limit of human body. After more than 15 minutes, the cornea will be irritated, eye pain, tearing, etc., serious You may be blind, your skin may be damaged, and you may get skin cancer. Therefore, when using the ultraviolet disinfection lamp, you must come out of the house immediately after turning it on, and turn it off immediately after the time is up. Do not stay for a long time to avoid affecting your body. The ultraviolet disinfection lamp can be sterilized when the house is closed when in use, so after turning on the disinfection lamp, close the doors and windows; when turning on the ultraviolet disinfection lamp, it is better to wear professional protective glasses to protect your eyes; preferably not to turn on the ultraviolet disinfection lamp for a long time, 15 minutes The disinfection task is completed in about half of the time; it is better not to place plants in the disinfection room to prevent disease.
Precautions for UV disinfection lamps
(1) During use, the surface of the UV lamp should be kept clean. Generally, wipe it with an alcohol cotton ball once every two weeks. When dust or oil stains are found on the surface of the lamp, wipe it at any time.
(2) When using ultraviolet lamps to disinfect indoor air, the room should be kept clean and dry to reduce dust and water mist. The temperature should be lower than 20℃ or higher than 40℃, and the relative humidity should be longer than 60%.
(3) When using ultraviolet rays to disinfect the surface of an article, the irradiated surface should be directly irradiated by ultraviolet rays, and a sufficient radiation dose should be achieved.
(4) Do not irradiate people with ultraviolet light source to avoid injury.
(5) If the operator must be on site, please be sure to wear LUV-40 UV protection mask!
The working principle of UV sterilization2020-09-15
The working principle of ultraviolet sterilization is to use bactericidal UVC ultraviolet rays (mainly 240 nanometers ~ 280 nanometers) to destroy the molecular structure of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) of microbial cells, causing growth cells and (or) Regenerative cell death achieves the effect of sterilization and disinfection. So how does the ultraviolet disinfection lamp emit UVC ultraviolet rays?Read More
At present, there are two main light sources of ultraviolet disinfection and germicidal lamps-gas discharge light sources and solid-state light sources.
The gas discharge light source is mainly a low-pressure mercury lamp. The light-emitting principle is the same as the fluorescent lamp we used before. It excites the mercury atoms in the tube. The low-pressure mercury vapor mainly produces 254nm UVC ultraviolet rays (radiation efficiency 30%~60%) and 185nm UVD ultraviolet rays (radiation efficiency 5%~15%) ).
The solid-state light source refers to the UV-LED light source. The radiation efficiency of UV-LED ultraviolet rays is several orders of magnitude lower than that of low-pressure mercury lamps, about 3% (here refers to imported chips, domestic chips are less than 2%). The current cost is also very high. To achieve the same unit radiation dose, its price is much more expensive than low-pressure mercury lamps. Some companies are already using UV-LED in water purifiers, air conditioners, and air purifiers. It is believed that with the decline in technology and cost in the future, they will be widely used in civilian fields.
How to choose a UV lamp?
At present, most of the ultraviolet disinfection lamps sold on the market still use the mature low-pressure mercury lamp light source. The low-pressure mercury lamp mainly has two glass materials-quartz glass and high boron glass. Just to say, the ultraviolet transmittance and radiation intensity of high boron glass are lower than those of quartz glass. You must choose quartz glass tubes to buy domestic brand ultraviolet germicidal lamps (tubes). UVC has a weak penetrating power and cannot penetrate ordinary glass. General consumers can’t distinguish the difference between quartz glass, high boron glass and ordinary glass, so when you buy ultraviolet disinfection lamps (tubes), don’t greedily choose miscellaneous goods. When you buy them back, they think they can light up. Sterilization may actually have no effect at all, and the silver was wasted.
