Photoinitiators yog dab tsi thiab koj paub ntau npaum li cas txog photoinitiators? Photoinitiators yog ib hom kev sib xyaw uas tuaj yeem nqus tau lub zog ntawm qee qhov wavelength hauv ultraviolet (250-420nm) lossis pom (400-800nm) cheeb tsam, tsim cov dawb radicals, cations, thiab lwm yam, thiab yog li pib monomer polymerization, crosslinking, thiab kho. . Txawm li cas los xij, lub wavelengths absorbed los ntawm cov photoinitiators sib txawv.
Kev faib tawm ntawm photoinitiators tuaj yeem faib ua ob pawg: dawb radicals thiab hom ionic. Dawb radicals tuaj yeem muab faib ua Hom I thiab Hom II; Hom Ionic tuaj yeem muab faib ua cationic thiab anionic hom. Lub photoinitiator yog qhov pib ntawm kev tsim, thiab nws qhov kev siv zaum kawg yog cuam tshuam los ntawm kev ua tau zoo thiab cov txheej txheem tsim. Muaj tsuas yog qhov tsim nyog tshaj plaws photoinitiator, tsis muaj qhov zoo tshaj plaws photoinitiator.
Photoinitiators nyob rau sab sauv hauv cov saw hlau. Cov ntaub ntawv raw hauv UV curing kev lag luam saw yog cov khoom siv tshuaj lom neeg thiab cov tshuaj tshwj xeeb, nrog rau photoinitiators nyob rau sab saud ntawm cov saw hlau. Lub series ntawm thiol tebchaw yuav siv tau raws li raw cov ntaub ntawv rau photoinitiators, thiab yog tsuas yog siv nyob rau hauv lub teb ntawm tshuaj thiab tshuaj tua kab manufacturing; Photoinitiators yog siv rau hauv ntau yam xws li photoresists thiab txhawb cov tshuaj, UV txheej, UV inks, thiab lwm yam., nrog rau cov ntawv thov davhlau ya nyob twg hla cov khoom siv hluav taws xob, kho kom zoo nkauj hauv tsev thiab cov khoom siv hauv tsev, tshuaj thiab kev kho mob, thiab lwm yam.
Muaj ntau hom photoinitiators nrog ntau hom kev siv, yog li peb yuav xaiv lawv li cas? Tom ntej no, cia kuv qhia koj yuav ua li cas xaiv ntau yam khoom uas tau ntsib.
Ua ntej, kuv xav qhiaphotoinitiator 819, uas tuaj yeem siv rau cov xim UV kho cov yas coatings. UV txheej, vim lawv cov kev ua tau zoo thiab kev tsim tau zoo, tau siv dav hauv cov plhaub yas ntawm ntau yam khoom siv hluav taws xob thiab khoom siv hauv tsev. Txawm li cas los xij, qhov sib sib zog nqus ntawm UV txheej tom qab xim tsis zoo, ua rau cov yeeb yaj kiab tsis zoo thiab tsis zoo dispersion thiab kev npaj ntawm cov xim los ntawm UV resins, cuam tshuam rau cov tsos ntawm cov coatings, yog li ntawd, cov txheej txheem kev tsim kho ib txwm yog thawj zaug siv cov kuab tshuaj raws li cov txheej txheem. cov xim primer rau xim, tom qab ntawd siv UV kua roj vanish tom qab ci los txhim kho ntau lub cev ntawm cov xim zaj duab xis nto.
Photoinitiator 184yog ib qho zoo thiab yellowing resistant dawb radical (I) hom khoom photoinitiator nrog qhov zoo ntawm lub sij hawm cia ntev, siab pib efficiency, thiab dav UV nqus ntau yam. Nws yog tsuas yog siv rau UV curing ntawm unsaturated prepolymers (xws li acrylic esters) ua ke nrog ib los yog ntau functional vinyl monomers thiab oligomers, thiab tshwj xeeb tshaj yog haum rau coatings thiab inks uas yuav tsum tau high yellowing degree.
Photoinitiator TPO-Lyog ib hom kua photoinitiator, uas yog siv nyob rau hauv lub formulation system uas tsis muaj yellowness thiab tsis muaj tsw. Nws yog feem ntau siv nyob rau hauv silk screen printing number case, Planographic printing number case, flexographic printing number case, photoresist, kua roj vanish, luam ntawv phaj thiab lwm yam teb.
Covphotoinitiator TPOfeem ntau yog siv rau hauv cov tshuab dawb, thiab tuaj yeem siv rau hauv UV curing coatings, luam ntawv inks, UV curing adhesives, Optical fiber coatings, photoresists, photopolymerization daim hlau, stereolithographic resins, composites, hniav fillers, thiab lwm yam.
Photoinitiator 2959 yog ib qho zoo uas tsis muaj yellowing photoinitiator nrog kev ua haujlwm siab, tsis tshua muaj ntxhiab, tsis yellowing, tsis muaj volatility, insensitivity rau oxygen polymerization, thiab high deg curing efficiency. Cov pawg hydroxyl tshwj xeeb uas yooj yim soluble hauv dej-raws li txheej. Tshwj xeeb tshaj yog haum rau dej-raws li acrylic esters thiab unsaturated polyesters. Photoinitiator 2959 kuj yog ib qho nplaum uas tau pom zoo los ntawm FDA daim ntawv pov thawj rau kev tsis sib cuag nrog zaub mov.
Benzophenoneyog ib tug dawb radical photoinitiator mas siv nyob rau hauv dawb radical UV curing systems xws li coatings, inks, adhesives, thiab lwm yam. Nws kuj yog ib tug nruab nrab ntawm organic pigments, tshuaj, txuj lom, thiab tshuaj tua kab. Cov khoom no kuj yog styrene polymerization inhibitor thiab fragrance fixative, uas tuaj yeem muab cov tshuaj tsw qab qab zib, thiab siv dav hauv cov tshuaj tsw qab thiab xab npum essence.
Cov khoom zoo ib yam li photoinitiators yog ultraviolet absorbers. Qee zaum, tib neeg feem ntau tsis tuaj yeem paub qhov txawv ntawm ob.UV absorberstuaj yeem hloov photoinitiators. Vim tias UV absorbers yog hom siv ntau tshaj plaws ntawm lub teeb stabilizer thiab tuaj yeem sib xws nrog lossis hloov photoinitiators rau kev siv, thiab lawv cov txiaj ntsig kuj zoo heev. Photoinitiators tshwj xeeb yog siv rau photocuring, inks, coatings, thiab tseem tuaj yeem siv rau hauv kev lag luam thiab hluav taws xob. UV absorbers muaj ntau yam kev siv, feem ntau yog siv hauv cov tshuaj pleev ib ce nrog cov kev xav tau zoo. Lub caij no, tus nqi ntawm ultraviolet absorbers yog qhov siab, thaum photoinitiators kuj tsawg. Koj tuaj yeem xaiv cov khoom sib xws raws li koj tus kheej xav tau.
Peb yog cov kws tshaj lij pib tsim khoom. Ntxiv nrog rau cov khoom uas tau hais los saum no, peb kuj muaj cov khoom zoo sib xws hauv qab no:
