How to safely use UV for sterilization under the new coronavirus outbreak?
Time:2022-12-19 Title:Air Conditioning Sterilizer Views:
The Diagnosis and Treatment Program for Pneumonia Infected by Novel Coronavirus (Trial Fifth Edition) issued by the General Office of the National Health and Wellness Commission states that the novel coronavirus is sensitive to ultraviolet light and heat.
Ultraviolet light is the natural enemy of most microorganisms and can easily kill them. SARS period, experts have found that the use of intensity greater than 90μW/cm2 UV irradiation for 30 minutes, can kill the SARS virus.
Research has found that there is a correlation between the new coronavirus and the SARS virus, and the scientific and rational use of ultraviolet light is effective in killing the new coronavirus.
So what is the safest and most effective way for the average person to use UV light in the fight against pneumonia from a new coronavirus infection.
How UV light kills the new coronavirus?
Chinese people have a special affection for the sun, that “ more sun can be sterilized ”.Sunlight itself contains ultraviolet rays, people's daily life in the sun quilt, drying clothes is the use of ultraviolet mites, disinfection and sterilization.
Ultraviolet light is actually radiation in the electromagnetic spectrum with wavelengths between 100 and 400 nanometers, and like infrared light, it cannot be seen by the human eye. UV light can damage the DNA and RNA structure in microorganisms, causing genetic material in viruses, bacteria and other microorganisms to break, cross-link or form photochemical products.
At the same time, ultraviolet light can also act on the oxygen atoms in the cells, causing them to form reactive oxygen radicals with killing power, which can cause microbial cells to be unable to proliferate or die directly. For example, if a person stands under the summer sun for some time, the skin will be sunburned, because human skin is also composed of cells, and cells and bacteria are biological.
The genetic material of the novel coronavirus, the culprit of the outbreak, is RNA, and ultraviolet light can act on the genetic material of the virus, causing the RNA of the virus to break, so that it can not normally synthesize the required proteins, thus killing the virus.s
However, you can't kill the new coronavirus by just relying on sun exposure. Sun exposure doesn't reach the temperature that kills the germs, so people still need to wear masks, goggles, etc. when they go out.
What do I need to be aware of when utilizing UV sterilization?
Compared with alcohol, disinfectant and other chemical disinfection products, ultraviolet light, as a relatively safe, economical, high sterilization rate of physical methods, is increasingly being used in people's daily lives. Because of the convenience of operation, can be applied to a wider range of products with ultraviolet sterilization function in the majorE-commercePlatforms are becoming sought after.
However, there are many things to keep in mind when using products with UV capabilities. First of all, the UVB in ultraviolet rays is the main component that causes sunburns on the skin. Prolonged exposure to ultraviolet rays can lead to skin pigmentation, thickening and roughness of the skin, photoaging, and in serious cases, cancer.
Secondly, the eye is the most sensitive part of the eye to ultraviolet light, long-term exposure can lead to phosphorus ions may be combined with calcium ions in the aging lens, resulting in calcification or sclerosis of the eye, which can lead to cataracts. This is when the clouding of vision in the eyes leads to cataracts.
How can I use the UV function of my appliances to decontaminate and sanitize?
In addition to the damage caused by UV light to the skin and eyes, the ozone produced by improper use of UV light can easily cause problems such as coughing, respiratory difficulties and reduced lung function.Therefore, it is best to use UV light for sterilization and disinfection in an enclosed space.

Chinese people pay attention to “ food, clothing, housing and transportation ”, many families believe that the clothing washed “ clean ”, however, some bacteria may still lurk in the depths of the fabric fibers, coupled with a lot of companies have resumed work! Inevitably, people have to go out and contact with people, the clothes are hidden many germs can not be seen with the naked eye, simple cleaning and drying can not effectively sterilize and disinfect.
Finally, consumers need to be reminded that
Although ultraviolet light can kill viruses, bacteria and other microorganisms in the external environment, but once these viruses enter the human body, ultraviolet light is not effective against them. Therefore, do not receive direct exposure to ultraviolet light, these practices are both ineffective and dangerous, but should seek medical attention in a timely manner.
