Kev Siv
Photoinitiator TPO yog ib qho tshuaj dawb radical (1) hom photoinitiator uas nqus tau zoo heev hauv qhov ntev wavelength. Vim nws qhov dav heev, nws qhov siab tshaj plaws ntawm kev nqus yog 350-400nm thiab nws nqus tau tas li txog li 420nm. Nws qhov siab tshaj plaws ntawm kev nqus ntev dua li cov tshuaj pib ib txwm muaj. Tom qab lub teeb pom kev zoo, ob qho dawb radicals, benzoyl thiab phosphoryl, tuaj yeem tsim tau, ob qho tib si tuaj yeem pib polymerization. Yog li ntawd, qhov ceev photocuring yog ceev. Nws kuj muaj cov nyhuv photobleaching thiab yog qhov tsim nyog rau cov zaj duab xis tuab thiab cov yam ntxwv ntawm cov txheej txheem tsis daj. Nws muaj qhov tsis tshua muaj volatility thiab yog qhov tsim nyog rau cov txheej txheem dej.
Nws feem ntau yog siv rau hauv cov tshuab dawb thiab tuaj yeem siv rau cov tshuaj pleev xim UV-curable, cov kua luam ntawv, cov nplaum UV-curable, cov tshuaj pleev xim fiber ntau, photoresists, cov phaj luam ntawv photopolymer, cov resins stereolithography, cov ntaub ntawv sib xyaw, cov ntaub ntawv txhaws hniav, thiab lwm yam.
Ua ib qho photoinitiator, nws feem ntau yog siv rau hauv cov tshuaj ntsuam luam ntawv, cov tshuaj ntsuam luam ntawv lithographic, cov tshuaj ntsuam luam ntawv flexographic, thiab cov txheej ntoo. TPO tuaj yeem kho tau tag nrho ntawm cov nplaim dawb lossis cov xim titanium dioxide siab. Nws yog siv dav hauv ntau yam txheej. Vim nws cov khoom nqus tau zoo heev, nws yog qhov tshwj xeeb tshaj yog rau cov tshuaj ntsuam luam ntawv, lithographic luam ntawv, cov tshuaj ntsuam luam ntawv flexographic, thiab cov txheej ntoo. Cov txheej tsis tig daj, muaj cov nyhuv tom qab polymerization qis, thiab tsis tawm cov khoom seem. Nws kuj tseem tuaj yeem siv rau hauv cov txheej pob tshab, tshwj xeeb tshaj yog haum rau cov khoom uas muaj qhov tsis tshua muaj ntxhiab. Thaum siv ib leeg hauv cov polyesters tsis muaj roj uas muaj styrene systems, nws muaj qhov ua tau zoo heev. Rau cov kab ke acrylate, tshwj xeeb tshaj yog cov kab ke xim, nws feem ntau yuav tsum tau siv ua ke nrog amines lossis acrylamides. Tib lub sijhawm, nws yog sib xyaw nrog lwm cov photoinitiators kom ua tiav kev kho ntawm lub kaw lus. Nws yog qhov tshwj xeeb tshaj yog haum rau kev kho ntawm cov kab ke qis-daj, dawb thiab cov txheej zaj duab xis tuab. Thaum siv lub photoinitiator TPO ua ke nrog MOB 240 lossis CBP 393, qhov kev kho kom zoo dua tuaj yeem txhim kho. Nws yog cov kuab tshuaj zoo tshaj plaws rau cov roj av aromatic hydrocarbon units thiab kuj siv ua cov tshuaj formylation hauv kev ua cov tshuaj zoo.
