Hightop - Professional UV light manufacturers and suppliers in China, providing the best customized service. Welcome to wholesale high quality UV light made in China here from our factory.
Uv light is a kind of gas discharge lamp, in which the quantitative high purity mercury is added into the vacuum quartz tube, and the voltage difference (voltage drop) is provided to both ends of the electrode to produce ionic discharge, thus generating ultraviolet radiation.
UV light is the abbreviation of ultraviolet lamp, UV is the abbreviation of ultra-violet Ray. This kind of lamp tube basically is to use the characteristic of ultraviolet ray to undertake actinic reaction, product solidification, disinfection, medical treatment is examined.
The role of uv lamps in the printing such as: offset printing, screen printing, 5-color printing, such as U disk, CD and often use uv protective adhesive production, in the optical disc printing, will use uv ink for screen printing, screen printing mostly use uv ink for printing. In the production process has a fast drying, good adhesion, various performance standards, adhesion, friction resistance and many other advantages.
The function of UV light is also shown in the industrial field of the PCB, LCD industry, for the circuit board printing generally use metal halide lamp, for exposure and development, the circuit board company is widely used. Due to the low pressure cold uv lamp and curing lamp with different, the use is also different.
