UV curing method and apparatus

摘要: A UV curing apparatus (300) and method is provided for enhancing of inks, coatings adhesives containing photoinitiators deposited on web(301) moved by rollers (302, 304, 306), subjecting them to light at different wavelengths. UV-LED assemblies (250) are alternated in rows emit wavelengths between 180 nm 420 nm. row emiting visible can be included reviewing the apparatus. cooling system (fans:312, 314, 316, 318; heat fins: 254) may maintain a desired temperature intensity. The placed distance from product provide uniform pattern diverging chips least 50% power output viewing cone angle 2θ1/2. ink, coating or adhesive have activated more than one wavelength.
