UV irradiated materials can be a coating, upper paint, ink or adhesive. The main ingredients are: 1. Single. 2. Pre -convergence .3. 4. 4. 5. Pigment or dye (ink) UV irradiated the light origin in the hardening material to absorb the light of the ultraviolet spectrum (wavelength 200-400nm) in the light of the light to produce a broken key. The single and pre -agglomeration reacts to the bridge, and instantly changes this material from liquid to solid state. Hardromation UV material. The main hardening conditions are: 1.uv illuminance => lamp output intensity, reflection reflection, reflection reflection, reflection The design of the mirror, the lighting distance, the thickness of the coating film. 2. UV energy => production efficiency, temperature. UV energy meter 3.UV spectrum distribution => tube type choice. Light ', irradiated UV material, made UV materials hardening, and reached the requirements of the product specifications of the industry. We call this' UV light' as the appropriate 'hardening condition'. UV ink composition 10-50%, a single 20-50, 2-10%of the starting agent (optical agent), additive 1-5%. Category: Four -colored Basic UV ink, special -colored UV ink, UV light oil.
UV LED diodes have become prevalent in an assortment of applications, including disinfection, industrial curing, and specialization light. Their value arises from their capacity to deliver accurate and efficient UV light tailored to individual requirements. Classical mercury lamps, which have been performing comparable roles, are steadily being replaced with UV LED diodes since of their greater performance and eco-friendliness. This article explains why UV LED diodes are an excellent choice for current applications.
The sole UV light source that could start the UV curing process forty years ago was mercury-based arc lamps. Even though Excimer lamps and microwave sources have been invented, the technology has not changed. Like a diode, an ultraviolet light-emitting diode (LED) creates a p-n junction using p- and n-type impurities. Charge carriers are blocked by a junction boundary depletion zone.
