UV lamp

UV lamp is referred to as UV lamp, and UV is the English abbreviation of Ultra-Violet Ray. This kind of lamp is mainly used for curing UV glue or UV ink by using the characteristics of ultraviolet rays, and also for sterilization.
Features


The UV lamp is a gas discharge lamp. The gas discharge lamp is divided into arc discharge and glow discharge. The UV lamp commonly used in UV curing is an arc discharge lamp. Its working principle is: adding quantitative high-purity mercury (mercury) to a vacuum quartz tube, By applying a voltage difference (voltage drop) across the electrodes, an ion discharge is generated, resulting in ultraviolet radiation. The power of the UV lamp should meet the requirements (generally 80-120W/cm); the UV lamp is generally recommended to use 1000h.

UV is the abbreviation of TEL (13 40 117 4352) in English. The spectral range of industrial UV light sources is 200nm-450nm, centered at 365nm. According to the different bands, UV-A, UV-B and UV-C have different uses.

 

The intensity of the UV lamp depends on the power density of the UV lamp tube. Generally, the commonly used specifications are:
80W/cm is 200W/inch
120W/cm is 300W/inch
160W/cm is 400W/inch
240W/cm is 600W/inch

 

UV curing is called UV Curing or UV Coating in English,) UV curing is a photochemical reaction, that is, a liquid UV-irradiated curable material is printed or coated on the surface of a substrate or workpiece, and the curing process is realized by UV light irradiation, UV curing Similar to the traditional drying process, but the principle is different. The traditional drying generally forms hardening by the volatilization of the solvent in the coating material, while the UV curing crosslinking does not have solvent volatilization.


Ultraviolet lamps (UV lamps) are gas discharge lamps. Gas discharge lamps are divided into arc discharge and glow discharge. UV lamps commonly used in UV curing are arc discharge lamps. The working principle is: adding a quantitative high Pure mercury (mercury), by applying a voltage difference (voltage drop) across the electrodes, creates an ion discharge, which produces ultraviolet radiation.
