Affected by the epidemic, the UVC disinfection series of products are hot, or daily necessities

Since the end of 2019, the continuous raging of new coronary viruses has caused global humans to face major disasters again. In the face of each disaster, we can always pass the difficulties because we will learn to face difficulties. The bacterial virus disaster has attracted our attention to the harmful bacteria of the virus, and it is necessary to take effective prevention measures.

Let's first understand the structure of the virus:

The virus is the smallest, the simplest type of non -cell microorganism, and the virus does not have a complete cell structure. The virus is mainly composed of nucleic acid and protein. At the periphery of the nucleic acid, there is a protein shell, called the shell, the shell and the nucleic acid are called a nucleus shell, no envelope virus, nucleus shell is the virus, the shell has antigenicity , Consisting of a certain amount of shell, each shell is composed of one or more polyphenol peptide. The surface of the virus is also wrapped with cell membrane -like cell membrane and spines, which determines the specificity of the virus with the shell. The more complex virus also has a envelope made of lipid and glycoprotein.

and the new coronary virus is very contagious. There are three ways to propagate the transmission. Drinking is the most important way to spread. Many viruses, these viruses will survive for a certain time in the air; if they do not bring good masks to protect them when going out, they are likely to inhale these viruses into nose and nose to infect diseases. The other two ways of communication are close contact and the spread of manure.

Therefore, it is extremely important to prevent prevention in daily life. Nowadays, disinfection products on the market use the characteristics of ultraviolet light sterilization and anti -virus.

The wavelength of ultraviolet light is shorter than visible light, but longer than X -rays. UV light is in electromagnetic spectrum, with a range wavelength of 10-400nm. This range begins with the short wave limit of visible light, while overlapping with the long wavelength of X -rays. Ultraviolet light is divided into three types: A ray, B -ray, and C -rays (referred to as UVA, UVB, and UVC), and the wavelength range is 400-315nm, 315-280nm, and 280-190nm .

sterilization is the most common function of ultraviolet rays. Because ultraviolet rays are powerful to creatures, humans use it to deal with these difficult bacteria and viruses, and we often use sunlight to sterilize. UV-A accounts for about 98.1%of the ultraviolet rays in the sunlight in nature, and UV-B accounts for about 1.1%. UV-C can hardly reach the surface of the earth due to the absorption of the ozone layer.

UV-B has a medium penetrating power, which is particularly strong in summer and afternoon, resulting in redness and sunburn in the skin in a short period of time. Reasonable irradiation can promote the formation of mineral metabolism and vitamin D in the body, and promote bone development, but long -term or excessive irradiation can cause skin redness and swelling. Most sunscreens in the market are used to protect UV-B ultraviolet rays.
