Waterborne UV txheej feem ntau suav nrog Waterborne UV resins, photoinitiators, additives thiab colouring coatings.Ntawm tag nrho cov khoom, Waterborne UV resin muaj qhov cuam tshuam loj tshaj plaws ntawm kev ua haujlwm ntawm Waterborne UV txheej.Kev ua tau zoo ntawm Waterborne UV resin cuam tshuam rau lub zog, kev tiv thaiv corrosion thiab kho rhiab heev ntawm cov yeeb yaj kiab kho ntawm qhov chaw ntawm txheej [1].Cov dej-raws li resin kuj cuam tshuam los ntawm photoinitiator.Raws li kev cuam tshuam ntawm photoinitiator, cov dej-raws li resin tuaj yeem kho tau hauv qab lub teeb.Yog li ntawd, photoinitiator kuj yog ib feem tseem ceeb ntawm Waterborne UV txheej.Kev tsim kho yav tom ntej ntawm photoinitiator yog polymerizable thiab macromolecular.
Qhov zoo ntawm Waterborne UV txheej: lub viscosity ntawm txheej tuaj yeem hloov kho yam tsis muaj diluting monomers, tshem tawm cov tshuaj lom thiab khaus ntawm cov txheej txheem ib txwm muaj.Rheological additives tuaj yeem muab ntxiv kom zoo los txo cov viscosity ntawm txheej txheej txheej, uas yooj yim rau txheej txheej txheej.Thaum lub txheej yog ua los ntawm cov yas thiab lwm yam ntaub ntawv, dej yuav siv tau raws li diluent los txhim kho cov adhesion ntawm txheej thiab txheej.Nws txhim kho cov plua plav pov thawj thiab khawb pov thawj muaj peev xwm ntawm txheej ua ntej kho, txhim kho cov txheej txheem tiav, thiab cov yeeb yaj kiab kho tau yog ultra-thin.Cov khoom siv txheej txheej yog yooj yim los ntxuav.Waterborne UVB txheej muaj cov nplaim hluav taws zoo.Txij li thaum tsis muaj qhov tsis tshua muaj molecular active diluent siv, yooj thiab hardness tuaj yeem txiav txim siab.
Waterborne UV resin coatings tuaj yeem sib txuas thiab kho tau sai sai raws li kev txiav txim ntawm photoinitiator thiab ultraviolet lub teeb.Qhov txiaj ntsig loj tshaj plaws ntawm cov dej hauv dej yog tswj tau viscosity, huv si, tiv thaiv ib puag ncig, txuag hluav taws xob thiab ua haujlwm siab, thiab cov qauv tshuaj ntawm prepolymer tuaj yeem tsim raws li qhov xav tau tiag tiag.Txawm li cas los xij, tseem muaj qee qhov tsis txaus hauv qhov system no, 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 siv 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, cov khoom siv ntau yam thiab hyperbranched.
(2) Tsim cov tshiab active diluents: nrog rau cov tshiab acrylate active diluents, uas muaj siab conversion, siab reactivity thiab tsawg ntim shrinkage.
(3) Kev tshawb fawb txog cov txheej txheem kho tshiab: txhawm rau txhawm rau kov yeej qhov tsis zoo ntawm kev kho tsis tiav qee zaum tshwm sim los ntawm kev txwv UV nkag mus, kev kho dual kho tau txais, xws li dawb radical teeb curing / cationic lub teeb curing, dawb radical lub teeb curing, thermal curing, dawb radical lub teeb curing / anaerobic curing, dawb radical lub teeb curing / ntub curing, dawb radical lub teeb curing / redox curing, thiaj li muab tag nrho cov kev ua si rau kev sib koom ua ke ntawm ob, Txhawb txoj kev loj hlob ntxiv ntawm daim ntawv thov teb ntawm cov khoom siv dej kho lub teeb. .
