2. Different colors. The light emitted by 365nm ultraviolet lamp basically does not contain purple, which is easy to identify; However, the light emitted by 395nm ultraviolet lamp shows strong purple, which sometimes affects judgment.
3, the scope of application is different. The use range of 365nm ultraviolet lamp is wider than that of 395nm ultraviolet lamp, and it can be used to identify the authenticity of almost all kinds of products.
Extended data
1. Ultraviolet lamp is a device that can emit ultraviolet rays, is a necessary tool to observe the fluorescence and phosphorescence characteristics of samples, and is also a physical means of sterilization. The wavelength is in the range of 10~400nm.
2. Related lamps include strong ultraviolet high-pressure mercury lamp, high-intensity metal halogen lamp, printing lamp, capillary ultra-high-pressure mercury lamp, optical cleaning lamp, CD-ROM special lamp, ultraviolet iron lamp, germicidal lamp, short arc xenon lamp, excimer discharge lamp, etc.
3. The ultraviolet lamp tube must be matched with ballast, leakage inductance transformer and capacitor in equal amount before it can be used.
4. Installation must be carried out according to the wiring diagram provided by the manufacturer.
5. The light box with the lamp tube must be equipped with a good air cooling system to ensure the heat dissipation of the lamp tube and prevent the substrate from being deformed by heat. 6. Before putting the tube on the machine, you must wipe off the handprints and oil stains on the outer wall of the tube with gauze, otherwise the tube will crystallize after ignition. If the volatile solvent content of UV curing material is high or the working environment is polluted by dust, please wipe the test tube with alcohol every other week to ensure the premature crystallization of the test tube.
7, the whole use process, should maintain good contact between the lamp holder and the lamp contact point, otherwise it will cause serious oxidation of the lamp holder, leading to the bursting of the lamp seal.
8. The ultraviolet lamp must be cooled before it can be started. ; When starting again, wait until the UV lamp is completely cooled before starting again, after 5 minutes; The more frequent the switch, the shorter the life of the lamp.
