Photoinitiator 250 yog hom tshwj xeeb ntawm photoinitiator siv hauv kev kho UV. Photoinitiators yog cov tshuaj sib xyaw ua ke uas pib los yog catalyze cov txheej txheem kho thaum raug ultraviolet (UV) lub teeb. Lawv ua lub luag haujlwm tseem ceeb hauv UV-kho cov tshuab, xws li inks, coatings, adhesives, thiab 3D printing resins.
Khoom: Photoinitiator 250 CAS 344562-80-7
Lub npe tshuaj: (4-Methylphenyl) [4-(2-methylpropyl)phenyl] iodonium hexafluorophosphate
Cov mis mos molecular: C17H20I.PF6
Molecular hnyav: 496.21
CAS Nr.: 344562-80-7
Photoinitiator 250, tseem hu ua 2,4, 6-Trimethylbenzoyl-diphenyl-phosphine oxide (TPO), yog ib qho zoo heev photoinitiator uas feem ntau siv nyob rau hauv UV-curable formulations. Thaum raug UV lub teeb ntawm ib lub wavelength tshwj xeeb, feem ntau nyob rau hauv thaj tsam ntawm 350 mus rau 400 nanometers, Photoinitiator 250 absorbs lub zog thiab ua rau cov tshuaj tiv thaiv photochemical, tsim cov dawb radicals lossis lwm hom reactive. Cov hom reactive no pib ua cov txheej txheem polymerization lossis crosslinking, ua rau kev kho lossis tawv tawv ntawm cov khoom siv UV-kho tau.
250 tuaj yeem siv ib leeg lossis sib xyaw nrog cov duab tsim nyog (xws li thiazolidone) rau UV curing inks, adhesives, ntawv, hlau, thiab cov kua roj vanish.

Photoinitiator 250 muaj qhov zoo xws li kev ua haujlwm siab, tsis muaj zog, thiab kev sib raug zoo nrog ntau yam monomers thiab oligomers siv hauv UV-kho tau. Nws yog tshwj xeeb tshaj yog zoo nyob rau hauv pib lub curing ntawm tuab txheej los yog nyob rau hauv formulations uas yuav tsum tau ceev curing ceev.
