What is the difference between ultraviolet sterilization and uv curing lights

  Almost, ultraviolet ray sterilizing lamp first for air sterilization, disinfection, water disinfection object appearance. Uv curing lamp first used in the uv curing ink and glue, photochemical reaction, etc
  How to distinguish ultraviolet ray sterilizing lamp and UV curing UV lamp
  Ultraviolet ray sterilizing lamp is actually due to a low pressure mercury lamp. Low pressure mercury lamp is to use low mercury vapor pressure (< 10-2 pa) was announced that uv light, the hair primary has two spectral lines: one is 253.7 nm wavelength; Another is 185 nm wavelength, and the two are invisible to the naked eye of ultraviolet light.
  How is the sterilization lamp sterilization?
  Sterilization lamp do not need to be converted to visible light, the wavelength of 253.7 nm can have very good sterilization effect, this is because the cell absorption spectral lines of light, there is a rule in the 250 ~ 270 nm uv light has the largest absorption, uv actually is absorbed on the cellular genetic material or DNA, it plays a allochromatic, ultraviolet photons energy absorbed by the base pairs of DNA, provoked attacks mutation genetic material, make the bacteria died immediately or cannot reproduce offspring, to reach the intention of the sterilization.

  The UV lamp can replace UV lamp UV curing
  Can't, ordinary ultraviolet lamp is for the use of sterilization, is a kind of low pressure mercury lamp, first in 254 and 185 nm wavelength. And UV ultraviolet lantern fair high pressure mercury lamp, some attend must be metal halide, improve its characteristics, make its main peaks to 365 nm, used for curing light. This is one of, the other is light curing lamp power density is high, can not reach normal uv lamp, ordinary is one hundred times one hundred times may have to be able to.
Can not! Although the wavelength of ultraviolet ray is about the same, but not enough strength. Do curing by ultraviolet (uv) light source are more than hundreds of watts of head, a tube to dozens of tile, more power difference curing time much longer.
  The UV curing light (UV light) launched after the end of the tube voltage is how many v? Power is 8 kw lamp,
  Hello, because we are a professional produce of the uv curing machine, your curing machine should be 1000, so the lamp power is 8 kw total should be 380 v voltage
The use of ultraviolet uv lamp have?
Ultraviolet uv lamp is widely used in PCB, LCD, electronic, printing, plastic, wood, footwear, glass, crafts glazing, painting and other categories.
  1, spraying aspects: common following from spraying, cosmetics case, MP3 use mostly small home appliance such as plastic spraying company, mobile phone shell coating with uv printing both career, about the uv supplication, see his product and equipment.
  2, printing: silk screen printing, offset printing, 5 color printing mostly use uv ultraviolet lamp dry curing uv ink.
  3, shoes: use ultraviolet light is shining on the soles of the data, the onset of chemical reaction, make the adhesive glue with good affinity with soles and uppers.
  4, wood: uv paint coating curing just for appearance. Due to uv coating (light oil, etc.) on various aspects function better, such as friction resistance, alkali resistance, weather resistance, etc.
  Career: 5, PCB PCB circuit boards, uv lamp used for printed circuit boards, common use METAL (METAL halogen lamp), other also is a kind of exposure lamp to METAL halogen lamp, PCB manufacturing, exposure to developing, normally used in the circuit board company.
  6, LCD career: is LCD display common cold low pressure uv lamp, and curing with tube is different, but were uv lamp, use is not the same.
  7, crafts glazing: as long as it is to use uv glazing oil processing handicraft appearance, uv tubes are available.
  8, uv coating line: actively before disposal project selection, using the electrostatic dust gun, maybe electrostatic dusting rods for disposal
