The working principle of UV light source is to apply energy to mercury so that it can be heated and evaporated rapidly. When the lamp reaches its working temperature, the mercury vapor becomes a plasma and emits the unique wavelength light of ionized mercury - ultraviolet.

Principle of UV curing: UV irradiation on the UV coating, the initiator in the coating absorbs UV energy, initiates UV resin reaction, completes the transformation of the coating from liquid phase to solid phase, and completes the curing. Because of its fast hardening speed, green environmental protection and other characteristics, UV curing technology has become the preferred production plan for furniture factory, printing factory and other enterprises.

In addition to the selection of UV lamps (power and spectral requirements) suitable for UV ink, paint and glue, the factors that affect the UV UV curing effect also affect the curing effect, such as heat dissipation conditions, reflective lampshade, working environment and conveying speed.
