Nowadays, people are obviously concerned about health, Microwave electrodeless ultraviolet sterilization equipment The demand of will be more and more extensive. Ultraviolet sterilization equipment It has high integration degree, low maintenance cost, saves the time and energy of operators, and does not need to add any other chemical reagents. Ultraviolet Sterilization equipment UVC ultraviolet rays play a real role in sterilization. Through ultraviolet radiation, the DNA (deoxyribonucleic acid) structure of microorganisms is destroyed and changed, so that bacteria die immediately or cannot reproduce, so as to achieve the purpose of sterilization.

UVC ultraviolet is a kind of light radiation whose wavelength is shorter than that of visible light. The ultraviolet rays in the wavelength range of 100-400 nm are generally divided into four categories: ① UV-A, ② UV-B, ③ UV-C, ④ UV-D, etc. Now let's understand the difference between the four UVC ultraviolet wavelengths:

1. UV-A long wave ultraviolet: the wavelength is 320~400 nm, and the penetration is strong, so the UVA ultraviolet in the sunlight can penetrate the ozone layer and clouds directly to the earth's surface. UVA can reach the dermis of the skin, directly damage the cells, tan your skin, and make your skin aging and wrinkled.

2. UV-B UVB: the wavelength is 280~320 nm, most of which are absorbed by the ozone layer, and only about 2%~10% reach the ground. It can promote the metabolism of minerals and the formation of vitamin D in the body. This is the reason why we often say to supplement vitamin D by properly basking in the sun. But too much sunburn will cause redness, swelling, pain and ecdysis.

3. UV-C short wave ultraviolet: the wavelength is 200~280 nm, which is almost completely absorbed by the ozone layer. The penetration ability is weak, and it cannot penetrate ordinary glass and plastic products. Although the penetration ability is weak, it does great harm to the human body and cannot directly irradiate the human body.

4. UV-D vacuum ultraviolet ray: the wavelength is 100~200nm, and the penetration ability is extremely weak. It can oxidize oxygen in the air into ozone.

Each standardized UV disinfection module is composed of a stainless steel lamp holder (304/316 material), UV lamp tube (effective service life of 12000 h), quartz sleeve (light transmittance ≥ 90%), and cleaning structure (using a central drive magnetic coupling cleaning cylinder). The entire UV disinfection system is composed of several UV disinfection modules for easy installation, operation and maintenance.
