Recently, the development of the epidemic has finally stabilized, and many small partners have begun to return to work one after another. Although it has not yet entered the full resumption of work, the resumption period of this period still cannot be taken lightly. So protective disinfection has become another top priority.

　　During the epidemic, all kinds of disinfection methods have been turned out, what 84 disinfectant, alcohol and even smoked white vinegar have been turned out. However, many people do have some negligence in their use. For example, the use of alcohol, many people usually directly take medical alcohol to spray on the body, in the car, at home, although 75% medical alcohol can achieve the purpose of killing the virus, but such a large area of spraying alcohol, in fact, very dangerous. Whether at home or in the car, if you encounter an open fire, such as the use of lighters, smoking, etc., it is easy to cause a fire, or even a fire.

　　Besides the disinfectant, there are two main components of the common 84 disinfectant, one is sodium hypochlorite and the other is sodium chloride. Although the disinfectant can also achieve the purpose of disinfection, these two substances are corrosive. For example, when disinfecting a car, these two substances are corrosive to the tires, exposed metal parts, and interior trim of the car. Accelerate aging.

　　ultraviolet disinfection lamp

　　And not only that, but also the emergence of a new way of disinfection methods, ultraviolet disinfection lamp. So this ultraviolet disinfection lamp in the end is not reliable? Today we will from the principle of the product to the use of the scene, the pros and cons of an analysis, with everyone to talk about ultraviolet disinfection lamp.

　　In fact, ultraviolet disinfection lamp is not a new species, as early as more than ten years ago during the period of SARS was hot fried. A simple understanding of ultraviolet disinfection lamp is a kind of lamp that uses ultraviolet sterilization to sterilize and disinfect. At the same time can also be called ultraviolet germicidal lamp, ultraviolet fluorescent lamp. Ultraviolet rays are rays with a wavelength of 10~400 nanometers in sunlight. At the same time, they can be divided into UVA (wavelength 320~400 nanometers, long wave), UVB (wavelength 280~320 nanometers, medium wave), and UVC (wavelength 100~280 nanometers, short wave) according to the wavelength.

　　The ultraviolet disinfection lamp is generally used for disinfection and sterilization in the UVC band, and the ultraviolet ray with a wavelength of 253.7 nm is usually used. Because the sterilization ability of this wavelength is the most powerful, the sterilization efficiency can reach 99% ~ 99.9. It can be used for disinfection and sterilization of water, air, clothing, etc.

　　The scientific principle of ultraviolet disinfection: it mainly acts on the DNA of microorganisms, destroys the DNA structure, makes it lose the function of reproduction and self-replication, so as to achieve the purpose of sterilization and disinfection, and has the advantages of colorless, tasteless and no chemical substance.

　　Can ultraviolet disinfection lamps kill the new coronavirus?

　　In the Fourth Edition of the Diagnosis and Treatment Program for Pneumonia Infected by Novel Coronavirus (Trial) published by the National Health Commission and the State Administration of Traditional Chinese Medicine, it is mentioned that the virus is sensitive to ultraviolet rays and heat, and the high temperature of 56°C lasts for 30 minutes,Ether, 75% ethanol, chlorine disinfectant, peracetic acid and chloroform and other lipid solvents can effectively inactivate the virus.That is to say, ultraviolet disinfection lamp is not only effective for sterilization, but also effective in the face of new coronavirus.

　　ultraviolet disinfection lamp on the human body there is no harm?

　　As we have said before, ultraviolet disinfection lamp disinfection has the advantages of colorless, tasteless and no chemical substances left behind, but if there is no protective measures in use, it will still cause great harm to the human body. As for the damage caused, it depends on the power and duration of the ultraviolet lamp.

　　The first cause of damage is the eyes, because the eyes contain a lot of protein, under the irradiation of ultraviolet rays, it will cause protein coagulation and denaturation, leading to corneal epithelial necrosis, shedding, and even corneal damage. Mild manifestations are swollen eyes, tears and a strong foreign body sensation.

　　In addition to the eyes, ultraviolet disinfection lamp damage to the skin is also very serious, light will appear red, swollen, itchy, desquamation, long irradiation time can even cause tumors and cancer. And damage to the body's skin cells, can lead to skin pigmentation, skin thickening rough, skin folds become aging. We search on the Internet. In recent years, it is not uncommon for ultraviolet disinfection lamps to cause things.

　　Although ultraviolet disinfection lamps are harmful to the human body, they do kill viruses, so in this very period of the epidemic, the use of ultraviolet disinfection lamps in homes, offices and cars is not reliable? Let's look at the life scene first, usually in the home and in the office scene, is the most frequent place for everyone to move. These scenes do need sterilization, but it is necessary to consider whether ultraviolet lamps are needed for sterilization.

　  First of all, it is impossible to disinfect the places that cannot be irradiated by ultraviolet lamps, that is to say, some backlights or dead corners with obstructions still cannot be completely disinfected. In addition, the use of ultraviolet lamps has certain requirements for indoor dust, water mist and humidity, and can also cause aging problems for some plastic furniture accessories. The most important thing is not to have direct contact with people, and ventilation should be carried out after disinfection, which is still troublesome. Moreover, according to experts, except in special cases, it is generally not necessary to use ultraviolet lamps to disinfect living quarters, because we do not need to kill all bacteria or viruses in these scenes.

　　Besides, in-car disinfection, the use of ultraviolet lamps in the car can only be used when there is no one, and some dead corners cannot be covered. At the same time, ultraviolet rays also accelerate the aging of the car interior. It is true that some taxi drivers have begun to disinfect their cars with ultraviolet lights, but that is because taxis receive more passengers every day, coupled with the epidemic period, which requires special treatment. Normal family cars are not used by so many people and frequency, and they do not need to be disinfected in this way. It is completely possible to use disinfectant and alcohol, but pay attention to the use method. Worried about corrosion like tire paint can be cleaned with clean water after disinfection.

　　At present, it is in the tense stage of virus prevention and control, and various disinfection methods are emerging one after another. The method of ultraviolet disinfection lamp to kill virus and sterilize is indeed feasible. However, the harm to the human body is greater, and there are certain risks and conditions in the use process. Moreover, as far as the actual situation is concerned, in fact, life scenes are not the same as medical scenes and require a truly sterile environment, so the use of ultraviolet lamps for disinfection in many ordinary life scenes is indeed a bit of a fuss.

　　We understand the principle of ultraviolet lamp, the use of the scene and its harm to the human body, in fact, everyone should have a point of view. From our own point of view, although ultraviolet lamps have the effect of killing viruses, dynamic air disinfection machines and alcohol or 84 disinfectant are used in these scenes. Because what we are doing is to prevent the virus, not to kill the new coronavirus. If there is a case in this scene, it may not be enough to simply disinfect the ultraviolet lamp. At present, the most effective way to prevent infection with the new coronavirus is to go out less, wear masks and wash your hands frequently.
