[UV] What Is Ultraviolet Rays and UVLED?

Ultraviolet rays are the general term of the wavelength of the electromagnetic spectrum from 10nm to 400nm, which cannot cause people's vision; UV is the English for short of ultraviolet rays, referred to as Ultraviolet. In 1801, German physicist Celtic discovered that at the outside of the purple -end of the fluorescent spectrum, a piece of photography containing silver bromide was light, and the existence of ultraviolet rays was discovered. Ultraviolet rays can be used for sterilization, too much ultraviolet rays enter the body will cause skin cancer to the human body. Ultraviolet rays are unsightly light located in Nikko High Energy Area. Ultraviolet rays are divided into: near ultraviolet rays (UVA), distant ultraviolet (UVB) and ultra -short UV (UVC). The degree of penetration of ultraviolet rays to human skin is different. The shorter the wavelength of ultraviolet rays, the greater the harm to human skin. Long wave ultraviolet can pass through the leather, and the middle wave can enter the leather. The characteristics of ultraviolet rays are: advantages: disinfection and sterilization, promoting bone development, beneficial to blood color, occasionally treating certain skin diseases and ultraviolet rays directly affecting the synthesis of human vitamin D, without sufficient vitamin D without ultraviolet rays. Disadvantages: make the skin aging, wrinkles, spots, causing rough skin and dermatitis, which can cause skin cancer in severe cases. UV industrial application A> The application in the surface cleaning treatment due to the progress of the development of high -power ultra -high power low -pressure UV discharge tube, and with the ultra -finest metaphysics of microelectronics, in microelectronics, ultra -precision devices and other products During the manufacturing process, the surface of its products is ultra -precision cleaning or improving the surface processing technology of the surface of the surface by short -wave length ultraviolet rays and its ozone. In the manufacturing of semiconductor devices, LCD representations, optical products and other manufacturing, the dry light surface treatment technology for ultraviolet UV and O3 ozone has become an indispensable technical means. As a replacement technology of Freon, the surface cleaning technology of light will gradually replace the wet traditional technology. B> Some materials used in general industries or high -tech fields in surface modification processing have very high performance and are also very good for the environment. The company provided by the short -wave length ultraviolet (UV) surface cleaning and surface modification technology, and uses clean high -energy ultraviolet light sources. After processing the above materials, it can get extremely clean surface and powerful surface. The basic reaction of modification is the oxidation reaction caused by UV. After UV irradiates the surface of the solid, the pollutants on the surface are oxidized, and then decompose to volatile substances such as CO2 and H2O, and eventually volatilize and disappear. And the surface forms favorable surfaces such as OH, COO, CO, COOH and other hydrophilic atoms. The progress of UV light source technology guarantees the UV/O3 surface modification technology to give full play to its outstanding superiority. UV/O3 Surface modification technology can obtain extremely high cleanliness and surface continuation, which is increasingly widely used in solid surface treatment. C> UV curing technology UV curing technology uses UV light (the main wavelength of 365nm, 254nm in special occasions) is illuminated by UV sclerosis in UV sclerosis containing compliance premature premature premature, light -focusing monomer, coating of light starting agent, continuous agent or ink, etc. After the resin, the technique of rapid hardening and drying in the second unit. The usual thermal drying method and the reaction method of the two liquid mixed legal need to be divided into several hours of drying the drying of resin. UV surface sterilization devices are widely used in food, electronics, semiconductors, LCD displays, plasma TVs, crystal vibrations, precision devices, chemicals, medical, health care, biology, drinks, agriculture, etc. UV light sources irradiated food, materials and other surfaces, which have a fast and efficient, pollution -free sterilization effect, thereby maintaining high quality of expensive products. UV sources are common in ultraviolet rays from sunlight. Ultraviolet rays used in industry are generally derived from special ultraviolet equipment, such as high -pressure mercury lamps, halogen lamps, etc. It is characterized by a full -band spectrum, high power consumption, effective ultraviolet rays parts (Such as 365nm, 395nm) is relatively efficient, bringing high calories and high power consumption to the industry. With the continuous maturity of semiconductor technology, the ultraviolet light sent through LED has become more and more popular in the market, which is what we often call UVLED. UVLED has the advantages of green, energy conservation, environmental protection, and efficiency, and has gradually become the mainstream of the market. TIANHUI has always regarded energy conservation and environmental protection and efficiency as the mission and pursuit of the enterprise, especially in UVLED curing technology and products.
