Waterborne UV txheej tuaj yeem sib txuas tau sai thiab kho tau raws li kev ua ntawm photoinitiators thiab ultraviolet lub teeb.Qhov zoo tshaj plaws ntawm cov dej-raws li resins yog tias cov viscosity tswj tau, huv si, ib puag ncig tus phooj ywg, txuag hluav taws xob thiab siv tau, thiab cov qauv tshuaj ntawm prepolymer tuaj yeem tsim raws li qhov xav tau tiag tiag.Txawm li cas los xij, qhov system no tseem muaj qhov tsis txaus, xws li kev ruaj ntseg ntev ntawm cov txheej txheem dej dispersion 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 yav tom ntej dej-raws li lub teeb kho tshuab yuav txhim kho hauv cov hauv qab no.
(1) Kev npaj cov oligomers tshiab: suav nrog cov viscosity tsawg, kev ua haujlwm siab, cov ntsiab lus siab, kev ua haujlwm ntau thiab kev ua haujlwm siab.
(2) Tsim cov reactive diluents tshiab: suav nrog cov tshiab acrylate reactive diluents, nrog rau siab hloov pauv tus nqi, siab reactivity thiab tsawg ntim shrinkage.
(3) Kev tshawb fawb ntawm cov txheej txheem kho tshiab: Txhawm rau kom kov yeej qhov tsis zoo ntawm kev kho tsis tiav qee zaum tshwm sim los ntawm kev txwv UV lub teeb nkag mus, siv ob lub tshuab kho, xws li dawb radical photocuring / cationic photocuring, dawb radical photocuring, thermal curing, dawb radical. photocuring, thiab dawb radical photocuring.Raws li photocuring / anaerobic curing, dawb radical photocuring / moisture curing, dawb radical photocuring / redox curing, thiab lwm yam., cov synergistic nyhuv ntawm ob yuav ua tau tag nrho exerted, uas txhawb txoj kev loj hlob ntxiv ntawm daim ntawv thov teb ntawm waterborne photocurable cov ntaub ntawv.
