Bayanin Abubuwan Da Suka Shafi UV LED Curing

Fitilar UV LED azaman tushen haske na gama gari, ka'idar warkarwa tana nufin tawada UV bayan hasken UV ya haifar da photoinitiator, don haka samar da radicals kyauta ko ions. Wadannan free radicals ko ions da pre-polymers ko unsaturated monomers a cikin biyu bond giciye-linking dauki, samuwar monomer genes, wadannan monomer genes fara sarkar dauki don samar da polymer daskararre daga kwayoyin.

Akwai abubuwa da yawa masu mahimmanci waɗanda ke tasiri maganin UV LED:

Curing kayan halayen

The curing gudun da tasiri naUV LED curing kayan aikiya dogara ne akan wahalar hasken don haifar da kwayoyin halitta a cikin kayan warkarwa. Ana ƙayyade maganin UV ta hanyar karo tsakanin photons da kwayoyin halitta. Hasken yana haifar da kwayoyin don yaduwa iri ɗaya ta cikin kayan. Baya ga halaye na kayan aikin warkewa, abubuwan gani da yanayin thermodynamic na kayan aikin warkewa da hulɗar su da makamashi mai haske suna da tasiri mai mahimmanci akan tsarin warkarwa.
