Taw qhia txog cov pab pawg ua haujlwm
Hauv kev npaj cov txheej txheem ntawm Waterborne UV txheej, cov pab pawg ua haujlwm thiab cov pob txha pob txha tuaj yeem polymerized ua ke los ntawm cov tshuaj tiv thaiv hluavtaws.Cov pab pawg ua haujlwm feem ntau yog fluorine thiab siloxane.Qhov sib ntxiv ntawm cov pab pawg ua haujlwm no tuaj yeem txo qhov nro ntawm cov yeeb yaj kiab kho kom zoo, ua kom yooj yim adhesion ntawm txheej txheej thiab txheej txheej, thiab ua kom cov adhesion ntawm cov xim zaj duab xis thiab substrate.Tsis tas li ntawd, vim muaj qhov muaj zog hydrophobicity ntawm cov pab pawg ua haujlwm xws li siloxane, cov xim zaj duab xis kuj muaj qee qhov kev kawm ntawm hydrophobicity, uas txhim kho cov dej-soluble kev ua tau zoo ntawm cov ntaub ntawv ib txwm muaj thiab txhim kho cov dej tsis kam thiab hnyav tsis kam ntawm cov xim zaj duab xis.
Strengthening curing system
Feem ntau, Waterborne UV txheej yog qhov nyuaj los kho, tshwj xeeb tshaj yog thaum siv hauv cov xim xim lossis cov txheej tuab.Ntxiv mus, vim qhov sib ntxiv ntawm photoinitiator, Waterborne UV txheej yog yooj yim kho nyob rau hauv ultraviolet irradiation.Txawm li cas los xij, thaum cov txheej txheem siv rau ntawm cov cuab yeej siv ntau dua, ultraviolet irradiation ntawm Waterborne UV txheej tsis tiav, uas ua rau qee cov txheej txheem nyuaj kho.Yog li ntawd, raws li qhov xwm txheej tam sim no, cov kws tshawb fawb tau tsim cov txheej txheem kho ntau txheej ntawm Waterborne UV txheej, uas daws tau cov kev txwv ntawm Waterborne UV txheej thiab nthuav dav daim ntawv thov ntau yam txheej txheej.
Siv cov txheej txheem hyperexpenditure
Vim tias muaj ntau pawg carboxyl nyob rau hauv Waterborne UV txheej, cov txheeb ze molecular hnyav ntawm pawg no yog loj.Yog li ntawd, viscosity ntawm Waterborne UV txheej yog qhov loj, uas txo cov ntsiab lus ntawm cov txheej txheem, uas muaj kev cuam tshuam tsis zoo rau cov xim xim thiab txo qhov gloss thiab dej tsis kam ntawm cov xim zaj duab xis.Yog li ntawd, txhawm rau txhim kho qhov tshwm sim no, cov kws tshawb fawb tau tsim cov txheej txheem hyperbranched hauv Waterborne UV txheej, txhim kho cov dej tsis kam ntawm cov xim zaj duab xis los ntawm cov pab pawg ua haujlwm loj, thiab siv cov yam ntxwv ntawm oligomers los txo cov viscosity ntawm lub kaw lus thiab txhim kho cov txheej txheem. gloss ntawm cov xim zaj duab xis.
Piv txwv li, vim qhov tshwj xeeb ntawm cov khoom siv ntawm Waterborne UV txheej, nws muaj qhov tshwj xeeb zoo piv nrog cov txheej txheem ib txwm muaj.Yog li ntawd, Waterborne UV txheej yog siv dav hauv cov ntoo thiab cov kua roj vanish.Vim tias qhov kev txhim kho tsis zoo ntawm Waterborne UV txheej, cov kws tshawb fawb tseem tab tom txhim kho kev ua haujlwm ntawm Waterborne UV txheej, ntxiv cov pab pawg ua haujlwm rau cov txheej txheej thiab tsim kom muaj ntau txheej txheej txheej.Tsis tas li ntawd, Kev siv cov txheej txheem hyperbranched hauv cov txheej txheem yog kev tshawb fawb yav tom ntej ntawm Waterborne UV txheej.Los ntawm kev txhim kho txuas ntxiv ntawm Waterborne UV txheej, lawv tuaj yeem muaj cov tshuaj toxicity qis dua, hardness ntau dua thiab zoo meej gloss.
