Infrared Curing

摘要

Infrared (IR) energy can be used as a source of heat to cure a variety of industrial coatings. Such infrared curing applies energy to the coated part surface by direct transmission from an IR emitter, which can provide source temperatures of anywhere from 500 to 4,200°F. Some of the energy is reflected off the surface, some is absorbed into the coating, and some heats the substrate. In powder coating, this direct transfer of energy creates an immediate reaction in the polymer, and curing (called crosslinking) begins quickly once the surface is exposed to the emitter. For paints and other coatings, infrared energy enables drying.
