UV for Ultraviolet short, that is, ultraviolet, ultraviolet lamps are referred to as UV lamps. Industrial UV light source spectral range is 200nm-450nm, centered on 365nm. According to the different bands, the lamp is divided into UV-A, UV-B, UV-C, each with different uses. Among them, UV-A can be seen with the naked eye, while the others are light that cannot be seen with the naked eye.
Two, UV lamp life is how long
UV lamp life generally refers to its ability to maintain sufficient energy for the operation of the time, during which its energy gradually decay until below the acceptable range. UV lamp life has a rated life, that is, its design life as well as the effective life, that is, the equipment light failure to reach 50% of the life of the two, usually need to look at the frequency of ultraviolet use, in general, the case of standard UV lamps can radiate enough UV energy up to 800 hours, imported UV lamps life of up to 1,500 hours or more, most of them are 1600 ~ 1800 hours.
Three, what are the specifications of the UV lamp
The intensity of the UV lamp depends on the power density of the UV lamp, generally used specifications are: 80W/cm that 200W/inch, 120W/cm that 300W/inch, 160W/cm that 400W/inch, 240W/cm that 600W/inch, can be customized according to user requirements Customized.
Four, ultraviolet UV lamp application range which
1, spraying industry
General spraying of cell phone shells, cosmetic shells, MP3 small household appliances shells and other plastic spraying companies mostly used to get the cell phone shells spraying and UV printing of these two industries, the requirements for UV are not the same, depending on his products and equipment. Cell phone shell spraying company, most of the 6-8 lamps (a coating line) as long as the parameters provided by the right, as long as you know the specifications and parameters of his uv lamps, you can ensure that the replacement.
2, the printing industry
Screen printing, offset printing, 5-color printing is mostly used. Like U disk and so on, CD-ROM and so on, with uv protective adhesive, in the CD-ROM printing, but also with uv ink for screen printing, in screen printing, most of the uv ink is used for printing. With fast drying, good adhesion, a variety of performance standards (adhesion, friction resistance, etc.).
3, the shoe industry
Use of ultraviolet light to irradiate the material of the sole, so that the chemical reaction, so that the adhesive glue and the sole and the upper have a good affinity with the shoe. Shoe industry, applicable to the adhesive, uv adhesive for plastic bonding, like the hospital infusion of plastic tubes of adhesive. General production of high-grade travel shoes company, can be used, the business of this industry, based on technology.
4, wood
Only surface coating, because uv paint (varnish, etc.) better performance in all aspects: such as abrasion resistance, acidity, alkalinity, weathering, etc., after uv coating, you can make the surface of wooden floors, such as glossy and gorgeous feeling. Wood painting, most of the lamps used in the length of the longer, more powerful mostly in the length of 1000mm or so.
5, PCB, LCD industry
pcb is a circuit board uv lamps used for circuit board printing generally use METAL (metal halide lamps), there is also a kind of exposure lamps also belongs to the metal halide lamps PCB production, used for the exposure of the development of the general use of the circuit board company. lcd is a display, generally use low-pressure cold ultraviolet lamps and curing lamps are not the same, but all the The lamp is not the same, but all belong to the ultraviolet lamp, the use is not the same.
6, crafts varnish
As long as it is used to uv varnish crafts, are available uv lamps.
7, uv automatic coating line
Pre-treatment project is used, the use of electrostatic dust gun, or electrostatic dust rod to deal with, which is often said: corona treatment, because plastic, plastic material, its surface tension is very poor, after corona treatment, the surface tension of the surface to improve the surface by strengthening the substrate and uv coatings affinity, so that there will be better Curing effect, if the pretreatment is not done well, the adhesion of the product will also have problems, many not the reason for the lamp, but the equipment or operating process problems, as well as, uv coatings or inks, there is also a great relationship.
8, sterilization
Low-pressure ultraviolet UV lamps, namely germicidal lamps, amalgam lamps are mainly used for sterilization, oil smoke purification, sewage treatment, waste gas treatment, etc., in addition to the UV-B is also mainly used for ultraviolet testing, medical treatment.
