Ultraviolet (UV) Technology solution
In 2020, an epidemic swept across the world. So far (November 2020), the global anti epidemic situation is still grim. While advocating wearing masks and safe distance, people's outlook on life has gradually changed, and a technology ultraviolet (UV) technology has been brought into fire.
What is ultraviolet (UV) technology?
Ultraviolet (UV) is the light invisible to the naked eye, which is divided into three parts: UV-A, UV-B and UV-C.
UV-A (wavelength range 315-400nm) radiation has a strong penetration, and more than 95% of the UV radiation that the skin is exposed to is UV-A, so it is the most harmful to the skin. At the same time, it can activate tyrosinase, leading to immediate melanin deposition and new melanin formation, making the skin black and lack of luster. The UV-A with 360nm wavelength accords with the phototaxis response curve of insects and can be used to make insect traps. UV-A ultraviolet light with 315-400nm wavelength can pass through the special colored glass lamp which can completely cut off the visible light, and only radiate the near ultraviolet light with the center of 365 nm. It can be used in the fields of ink glue solidification, ore identification, stage decoration, banknote inspection, etc.
UV-B (wavelength range of 280-315nm) radiation has medium penetration. Most of the UVB in sunlight will be absorbed by the ozone layer, and only a small part can reach the earth's surface. UV-B ultraviolet rays can oxidize the protective lipid layer of the epidermis and dry the skin; furthermore, it denaturates the nucleic acid and protein in the epidermal cells, resulting in acute dermatitis for example sunburn, and the skin will turn red and painful. If to the Serious degree, it will be easy to cause skin cancer. In addition, the long-term damage of UV-B can also cause the variation of melanocytes, resulting in the sun spots that are difficult to eliminate. UV-B is often applied to plant growth lights.
UV-C (wavelength range 100-280nm) radiation is a recognized disinfection method, which has been widely used for more than 40 years. It applies to air, water and surfaces and helps reduce the risk of infection. UV-C disinfection works on all bacteria and viruses tested so far (hundreds of them have been tested over the years, including various coronaviruses). There is no known pathogen that can tolerate UV-C ultraviolet. This clearly shows that UV-C UV can play an important role in your protection strategy.
