Cov txheej UV uas ua los ntawm dej tuaj yeem sib txuas thiab kho tau sai sai hauv qab kev ua ntawm cov photoinitiators thiab lub teeb ultraviolet. Qhov zoo tshaj plaws ntawm cov resins uas ua los ntawm dej yog tias qhov viscosity tuaj yeem tswj tau, huv si, zoo rau ib puag ncig, txuag hluav taws xob thiab ua haujlwm tau zoo, thiab cov qauv tshuaj ntawm prepolymer tuaj yeem tsim raws li qhov xav tau tiag tiag. Txawm li cas los xij, lub kaw lus no tseem muaj qhov tsis zoo, xws li kev ruaj khov mus sij hawm ntev ntawm lub kaw lus dispersion dej txheej yuav tsum tau txhim kho, thiab kev nqus dej ntawm cov yeeb yaj kiab kho yuav tsum tau txhim kho. Qee cov kws tshawb fawb tau taw qhia tias cov thev naus laus zis kho lub teeb uas ua los ntawm dej yav tom ntej yuav tsim kho hauv cov hauv qab no.
(1) Kev npaj cov oligomers tshiab: suav nrog viscosity qis, kev ua haujlwm siab, cov ntsiab lus khov kho, ntau yam kev ua haujlwm thiab hyperbranching.
(2) Tsim cov tshuaj diluent tshiab: suav nrog cov tshuaj diluent acrylate tshiab, nrog rau tus nqi hloov pauv siab, kev ua haujlwm siab thiab kev ntsws me me.
(3) Kev tshawb fawb txog cov txheej txheem kho tshiab: Txhawm rau kov yeej qhov tsis zoo ntawm kev kho tsis tiav qee zaum los ntawm kev nkag mus rau hauv lub teeb UV tsawg, ob txoj kev kho tau siv, xws li free radical photocuring / cationic photocuring, free radical photocuring, thermal curing, free radical photocuring, thiab free radical photocuring. Raws li photocuring / anaerobic curing, free radical photocuring / moisture curing, free radical photocuring / redox curing, thiab lwm yam, cov nyhuv synergistic ntawm ob qho tuaj yeem ua tiav, uas txhawb nqa kev txhim kho ntxiv ntawm daim ntawv thov ntawm cov khoom siv photocurable dej.
