Lub teeb pib (photoinitiator), tseem hu ua photosensitizer (photosensitizer) lossis lub teeb curing agent (photocuring agent), yog ib hom tshuaj lom neeg uas tuaj yeem nqus tau qee qhov wavelengths ntawm lub zog, tsim cov dawb radical thiab cationic hauv thaj tsam uv (250 ~ 420 nm) lossis pom lub teeb pom kev zoo (400 ~ 800 nm) kom pib ntawm monomer polymerization crosslinking curing.
TPO-L flos yog xim daj qis, xim dawb UV;
TPO-Lrau UV screen printing inks, UV offset printing thiab UV flexo inks;
TPO-Lcov kua roj vanish uas tsis muaj ntxhiab tsw qab, xim pleev ua los ntawm ntawv, phaj luam ntawv uas tiv taus lub teeb, stereolithography.
Tus photoinitiator TPO-L yog ib qho kua UV initiator rau ib qho acrylic-muaj resin thiab ib tug styrene-muaj unsaturated polyester. Txij li thaum nws yog kua, lub photoinitiator TPO-L yog "yooj yim ntxiv" rau txhua cov qauv. Vim tias TPO-L nqus cov wavelengths ntev hauv UV spectrum, nws kuj kho tau tag nrho cov txheej txheej nrog titanium dioxide thiab cov txheej txheej tiaj tiaj nrog titanium dioxide. Cov txheej txheej tau txais yog tus cwj pwm los ntawm kev daj tsawg heev.
Vim nws qhov volatility qis, tus photoinitiator TPO-L yog tsim rau kev tsim cov qauv tsw qab tsawg. Tus photoinitiator TPO-L tau ntxiv rau hauv qhov sib piv ntawm 0.3 txog 5%, thiab qhov polymerizable tau muaj nyob rau hauv cov xim thiab cov kua luam ntawv.
Tus photoinitiator TPO-L feem ntau yog ua ke nrog lwm cov photoinitiators xws li photoinitiator 184, photoinitiator 1173, photoinitiator TZT lossis benzophenone. Qhov no txhawb nqa kev kho qhov chaw. Vim tias TPO-L nqus tau cov UV ntev ntev, nws rhiab heev rau lub hnub ci nrog cov khoom uas muaj nws. Yog li ntawd, nws yog qhov tsim nyog yuav tsum tsis txhob muaj lub teeb uas muaj qhov ntev ntev dua 500 nm thaum khaws cia thiab tuav (piv txwv li, qhov rais thiab teeb pom kev zoo raug npog nrog zaj duab xis daj).
