Fighting  "epidemic"  becomes the unanimous action of all the people in the Spring Festival of 2020. After experiencing a hard time to get a Mask. Our circle of friends is gradually focusing on the UV sterilization lamp.

So some people questioned, can UV Sterilization lamp kill new coronaviruses? It was mentioned in the "Fourth Edition of the New Coronavirus Infection Pneumonia Diagnosis and Treatment Program (Trial)" published by the National Health and Health Commission and the State Administration of Traditional Chinese Medicine, The virus is sensitive to ultraviolet rays and heat. The high temperature of 56℃ lasts for 30 minutes. Diethyl ether, 75% ethanol, chlorine-containing disinfectant, peracetic acid and chloroform can effectively inactivate the virus. Therefore, UV sterilization lamps are effective in killing viruses. How are UV sterilization lamps disinfected?

Ultraviolet lamps, also called UV sterilization lamp, as the name implies, its are a device that can generate ultraviolet rays, and its wavelength range is between 10 and 400nm.

Ultraviolet rays can be divided into different types such as UV-A, UV-B, UV-C according to the length of wavelength, Energy level gradually increases. The UV-C band (100nm~280nm) is generally used for disinfection and sterilization. The UV sterilization lamp uses the ultraviolet light emitted by the mercury lamp to realize the sterilization and disinfection function. Ultraviolet sterilization technology has unmatched sterilization efficiency of other technologies, sterilization efficiency can reach 99%~99.9%. Its scientific principle is mainly acting on the DNA of microorganisms. Destroying DNA structure, making it losing the function of reproduction and self-replication to achieve the purpose of sterilization and disinfection.

Are UV Sterilization lamps harmful to humans? Ultraviolet sterilization has the advantages of colorless, odorless and chemical substances. But if there is no protective measures during using it, it is easy to cause huge harm to the human body. For example, bare skin is irradiated by this type of ultraviolet light, and People will may appear red, swollen, itchy, and desquamative; some people  are serious, may even cause cancer and skin tumors. At the same time, it is also an "invisible killer" of the eyes, which can cause inflammation of the conjunctiva and cornea. Ultraviolet rays also damage human skin cells and cause premature skin aging. In the recent special period, People hurt by improper use of ultraviolet disinfection lamps have occurred frequently.

So if you buy a UV Sterilization lamp, you must keep in mind when using it:

1. When using UV Sterilization lamps, people, animals and plants must leave the scene;

2. The eyes should not stare at the UV Sterilization lamp for a long time. Ultraviolet rays have a certain damage to human skin and mucous membranes. Pay attention to protection when using UV Sterilization lamps. The eyes must never look directly at the ultraviolet light source, otherwise the eyes will be injured;

3. When sterilizing items with an ultraviolet disinfection lamp, spread or hang the items to expand the irradiation surface, the effective distance is one meter, and the irradiation can be about 30 minutes;

4. When using UV Sterilization lamps, the environment should be kept clean, and there should be no dust or water mist in the air. When the indoor temperature is below 20 degrees Celsius or the relative humidity exceeds 50%, the exposure time should be extended. After scrubbing the ground, the ultraviolet light should be disinfected after the ground is dry;

5. After using the ultraviolet disinfection lamp, remember to ventilate for 30 minutes before entering the room. Finally, we suggest that if your family has not been diagnosed with a patient, you do not need to disinfect household items. Because we don't have to kill all bacteria or viruses in life, the most effective way to prevent infection with the new coronavirus is: go out less, wear masks, and wash hands frequently.
