Ukuqaliswa kwamaqela asebenzayo
Kwinkqubo yokulungiselela i-Waterborne UV yokugquma, amaqela asebenzayo kunye ne-polymer skeleton inokwenziwa i-polymerized kunye nge-synthetic reaction.Amaqela asebenzayo asetyenziswa ngokuqhelekileyo yifluorine kunye ne-siloxane.Ukongezwa kwala maqela asebenzayo kunokunciphisa ngokufanelekileyo ukunyanzeliswa komphezulu wefilimu ephilisiweyo, kuququzelele ukunamathela okungcono phakathi kokugqoka kunye nokunyusa, kunye nokwandisa ukunamathela phakathi kwefilimu yepeyinti kunye ne-substrate.Ukongezelela, ngenxa ye-hydrophobicity eqinile yamaqela asebenzayo afana ne-siloxane, ifilimu yepeyinti nayo inezinga elithile le-hydrophobicity, eliphucula ngokufanelekileyo ukusebenza kwe-soluble yamanzi yezinto zendabuko kunye nokuphucula ukuxhathisa kwamanzi kunye nokuxhatshazwa kwe-solvent yefilimu yepeyinti.
Ukomeleza inkqubo yokunyanga
Ngokubanzi, i-Waterborne ye-UV yokugquma kunzima ukuyinyanga, ngakumbi xa isetyenziswa kwiinkqubo ezinemibala okanye iingubo ezishinyeneyo.Ngaphezu koko, ngenxa yokongezwa kwe-photoinitiator, i-Waterborne UV yokugquma kulula ukunyanga phantsi kwemisebe ye-ultraviolet.Nangona kunjalo, xa i-coating isetyenziswe kwizixhobo ezinzima ngakumbi, ukukhanya kwe-ultraviolet kwi-Waterborne UV ye-UV ayiphelelanga, nto leyo eyenza kube nzima ukunyanga ezinye iingubo.Ngoko ke, ngokwemeko yangoku, abaphandi baye baqulunqa inkqubo yokunyanga i-multi-layer ye-Waterborne UV ye-UV, eyisombulula ngokufanelekileyo imida ye-Waterborne UV ye-UV kunye nokwandisa uluhlu lwezicelo zeengubo.
Ukusebenzisa inkqubo ye-hyperexpenditure
Ngenxa yokuba maninzi amaqela e-carboxyl kwi-Waterborne UV yokugquma, ubunzima bemolekyuli beli qela bukhulu.Ngako oko, i-viscosity ye-UV ye-UV ye-Waterborne ikhulu kakhulu, eyanciphisa umxholo oqinileyo wokugquma, onefuthe elibi kwifilimu yepeyinti kunye nokunciphisa i-gloss kunye nokuchasana kwamanzi kwifilimu yepeyinti.Ngoko ke, ukuze kuphuculwe le nto, abaphandi baye baseka inkqubo ye-hyperbranched kwi-Waterborne UV iingubo, baphucula ukunyanzeliswa kwamanzi kwifilimu yepeyinti ngokusebenzisa amaqela amakhulu asebenzayo, kwaye basebenzise iimpawu zesakhiwo se-oligomers ukunciphisa i-viscosity yenkqubo kunye nokuphucula i-viscosity yenkqubo. Iglosi yefilimu yepeyinti.
Ukushwankathela, ngenxa yobungcali bezinto eziqulethwe yi-Waterborne UV yokugquma, ineengenelo ezikhethekileyo xa kuthelekiswa neengubo zemveli.Ngoko ke, iingubo ze-UV ze-Waterborne zisetyenziswa ngokubanzi kwi-varnish yomthi kunye nephepha.Ngenxa yophuhliso olungafezekanga lweengubo ze-UV ze-Waterborne, abaphandi basaphucula ukusebenza kweengubo ze-UV ze-Waterborne, zongeza amaqela asebenzayo kwiingubo kunye nokuseka inkqubo yokunyanga i-multi-layer.Ukongeza, Ukusetyenziswa kwenkqubo ye-hyperbranched kwi-coatings lukhokelo lophando lwexesha elizayo lwe-Waterborne UV yokugquma.Ngokuphucuka okuqhubekayo kweengubo ze-UV eziphuma emanzini, zinokuba netyhefu esezantsi, ubulukhuni obukhulu kunye neglosi egqibeleleyo.
