Ultraviolet (UV) curing is to use the photosensitivity of photoinitiator (photosensitizer) to trigger the formation of excited ecological molecules and decompose them into free radicals or ions, so that unsaturated organic compounds can undergo chemical reactions such as polymerization, grafting and crosslinking to achieve the purpose of curing.
Types and uses of ultraviolet curing lamps
1, shadowless adhesive curing lamp
Shadow-less adhesive curing lamp refers to an adhesive that can only be cured by ultraviolet radiation. Can be used as adhesive, paint, ink, etc. The adhesive can only be cured by corresponding ultraviolet irradiation.
UV-curing lamps are mainly used as fast curing light sources for large-area bonding, fixing and assembly, such as publishing, video, glass technology, glass furniture, glass sliding door, glass photo, strengthened glass and crystal technology.
2.UV glue /UV ink curing lamp
It is a high-pressure gas discharge lamp used as an ultraviolet light source. Its main peak of ultraviolet output is 365NM, and its power density and ultraviolet output are strong, and its curing time is short. There are two types of lamp holders: top type and porcelain head type. Its working face is small, and it is suitable for printing plate making, soft package color printing, furniture industry, decorative materials, paper glazing, automobile and motorcycle plastic parts, printing cans, UV ink on plastic packaging surface, UV varnish curing, semiconductor printed circuit boards, signs and other industries.
