Photoinitiator TPO hmoov 98% CAS 75980-60-8 TPOP
Photoinitiator TPO hmoov 98%CAS Nr .: 75980-60-8TPOP
TPO yog qhov ua tau zoo ntawm cov dawb radical (1), qhov ua tau zoo ntawm qhov muag pom ntawm tus pib hauv qhov ntev wavelength. Vim tias nws muaj ntau yam kev nqus, qhov nqus siab tshaj plaws yog 350-400nm, tau tshwm sim los ntawm kev nqus ntawm 420nm, nws qhov nqus nqus siab tshaj li cov neeg pib pib ntev dhau lawm, lub teeb tuaj yeem tsim benzoyl thiab phosphoryl ob.
dawb radicals tuaj yeem ua rau polymerization, yog li lub teeb curing ceev, nws kuj muaj photobleaching, haum rau tuab zaj duab xis txheej thiab sib sib zog nqus curing yellowing yam ntxwv nrog tsawg volatile, rau dej. Cov khoom no yog siv rau lub cev dawb, tuaj yeem siv rau UV curing coatings, luam ntawv inks, nplaum, UV kho qhov muag fiber ntau txheej, photoresist, photopolymerization phaj, stereo lithographic resin, cov ntaub ntawv sib xyaw, kev kho hniav thiab lwm yam.. Kev siv cov khoom no yuav tsum tau ua raws li qhov tseeb ntawm qhov kev sim, nws raug pom zoo kom ntxiv qhov nyiaj ntawm 0.5-4% w / w. Nws tuaj yeem ua tiav tag nrho ntawm cov xim dawb lossis siab titanium dioxide xim. Lub txheej tsis hloov, cov nyhuv ntawm polymerization yog tsawg, thiab tsis muaj residue. Kuj tseem siv tau rau cov pob tshab txheej, tshwj xeeb tshaj yog rau cov khoom tsis muaj ntxhiab tsw. Nws yog siv nyob rau hauv unsaturated polyester uas muaj styrene system, uas muaj high efficiency. Cov txheej txheem acrylate, tshwj xeeb tshaj yog cov xim xim, feem ntau yuav tsum tau koom tes nrog amine lossis acrylamide, thiab lwm yam teeb pom kev zoo, kev kho kom ua tiav kev kho kom zoo yog qhov tshwj xeeb tshaj yog tsim rau cov xim daj, dawb thiab tuab. Screen printing number case, offset luam ntawv number case. Pom zoo ntxiv tus nqi ntawm 0.5-3.0% (xim system), 0.3-2.0% (pob tshab system.
