Kev siv
Diamininitiator TPO yog ib qho kev ywj pheej ntau tshaj plaws (1) Hom Yeesininitiat uas nqus tau ntev ntev ntev. Vim yog nws txoj kev nqus tau dav heev, nws txoj kev nqus tau zoo peak yog 350-400nm thiab nws nqus tsis tu ncua txog li 420NM. Nws txoj kev nqus lub ncov ntev ntev dua li ntawm cov pib ua ntej. Tom qab lub teeb meem, ob lub radicals, benzoyl thiab phosphoryl thiab phosphoryl, tuaj yeem tsim tawm, ob qho tib si tuaj yeem pib polymerization. Yog li ntawd, cov photocuring ceev yog nrawm. Nws tseem muaj cov nyhuv ntawm cov khib nyiab thiab haum rau tuab zaj duab xis sib sib zog nqus cov tshuaj ntsuam thiab cov yam ntxwv ntawm cov txheej daj tsis-yellowing. Nws muaj qhov tsis khov khov thiab yog qhov haum rau cov tshuab lim dej.
Nws feem ntau yog siv nyob rau hauv cov tshuab dawb thiab tuaj yeem siv rau UV-deshiums, UV-cov khoom siv roj pleev, cov khoom siv ntsuas hluav taws xob, cov khoom siv ntsuas hluav taws xob, tshuaj ntxuav hniav, thiab lwm yam.
Ua tus kws yees duab thaij duab, nws yog siv nyob rau hauv kev tshuaj ntsuam Inks, lithographic Printing inks, thiab ntoo txheej txheem. TPO tuaj yeem kho tiav ntawm dawb lossis siab titanium dioxide pigmented nto. Nws yog dav siv nyob rau hauv ntau txheej txheej txheej. Vim nws cov khoom nqus tau zoo heev, nws yog tshwj xeeb rau cov tshuaj ntsuam Inks, Lithgrocic Printing inks, thiab ntoo txheej txheem. Cov txheej tsis tig daj, muaj cov nyhuv post-polymerization qis, thiab nplooj tsis muaj qhov seem. Nws kuj tseem tuaj yeem siv rau hauv cov pob tshab, tshwj xeeb yog tsim rau cov khoom lag luam nrog cov ntxhiab tsw tsawg. Thaum siv ib leeg nyob rau hauv cov polyesturers tsis muaj styrene systems, nws muaj qhov pib ua haujlwm zoo heev. Rau kev siv hlwb, tshwj xeeb tshaj yog cov xim xim, feem ntau nws yuav tsum tau siv ua ke nrog amines lossis acrylamides. Nyob rau tib lub sijhawm, nws yog compounded nrog lwm cov duab thaij kom ua tiav kev kho kom tiav. Nws yog qhov tshwj xeeb rau kev kho kom zoo ntawm cov daj daj, dawb tshuab thiab tuab zaj duab xis txheej. Thaum tus kws kho duab thaij duab TPO yog siv hauv kev sib xyaw nrog cov neeg muaj kev sib xyaw 2493, kev kho kom zoo tuaj yeem hloov kho. Nws yog qhov zoo tshaj plaws txhaj tshuaj rau cov roj av muaj ntxhiab thiab tseem siv los ua cov reagation hauv kev ua haujlwm ntawm cov tshuaj tua tau zoo.
