How effective is the use of UV sterilizers than traditional equipment for sterilization?
This page mentions the advantages and disadvantages of ultraviolet sterilization to fight viruses and bacteria and use ultraviolet light for sterilization. It mentions the benefits or advantages of UV sterilizers and the disadvantages of UV sterilization. First, let’s understand what a UV sterilizer is?
1. What is a UV sterilizer?
An uv sterilizer is a device that uses ultraviolet rays for sterilization. Ultraviolet rays are invisible to us, and are further divided into three types according to their wavelengths. Types include UV-A, UV-B, and UV-C.
Ultraviolet-carbon occupies the range of 100 to 280 nanometers. It is found that 265nm or 254nm ultraviolet radiation is very effective in killing bacteria or viruses. In the course of the research, it was discovered that exposure to specific wavelengths of ultraviolet light can kill the viruses present in the air droplets. And this ultraviolet light is safe to use around humans.
Equipment based on UVC lamps is used in many applications, such as the disinfection of drinking water, air, pharmaceutical tools, and the disinfection of vegetables and fruits. In order to prevent the spread of the virus, ultraviolet lamps are used to disinfect mobile phones, surfaces, clothes, appliances, toys, etc. There are many UV-based devices, including UV phone boxes, UV disinfection lamps, UV light stick disinfectors, UV-based robots, etc. Ultraviolet robots used in hospitals are used to disinfect patients' rooms and clothes.
2. the benefits or advantages of UV sterilization
1. The following are the benefits or advantages of UV sterilization:
UV disinfection equipment is more effective than traditional cleaning methods.
No chemicals are required for UV disinfection. In addition, this method does not leave any chemical residues on the target. Therefore, it is safe to use. In addition, it will not cause any harm to humans.
UV sterilization is an environmentally friendly method.
The UV light disinfection method is a dry method, so it can prevent the growth of fungi very effectively.
The cost of UV light-based sterilizer is lower. In addition, they have a longer lifespan.
2. Disadvantages or shortcomings of ultraviolet sterilization
The following are the disadvantages or disadvantages of UV sterilization:
The UV sterilizer works effectively in its direct light path. When the light is blocked by an object, it becomes invalid. Therefore, it is necessary to ensure that the object is placed directly on the path of the ultraviolet light. In order to minimize the problem, a larger number of UV bulbs are used in the UV sterilizer to cover a wide-angle range.
UV light has harmful effects on our eyes and skin. It often causes chronic eye damage. Therefore, it is not recommended to use UV lamps to disinfect hands and skin.
