Ukwethulwa kwamaqembu asebenzayo
Enqubweni yokulungiselela i-Waterborne UV enamathela, amaqembu asebenzayo kanye nohlaka lwamathambo e-polymer kungenziwa i-polymerized ndawonye ngokusabela kokwenziwa.Amaqembu asebenzayo asetshenziswa kakhulu yi-fluorine ne-siloxane.Ukwengezwa kwalawa maqembu asebenzayo kunganciphisa ngokuphumelelayo ukungezwani kwendawo yefilimu ephulukisiwe, kube lula ukunamathela okungcono phakathi kokugqoka nokugqoka, futhi kwandise ukunamathela phakathi kwefilimu kapende ne-substrate.Ngaphezu kwalokho, ngenxa ye-hydrophobicity eqinile yamaqembu asebenzayo afana ne-siloxane, ifilimu yepende nayo inezinga elithile le-hydrophobicity, elithuthukisa ngokuphumelelayo ukusebenza okuncibilikayo kwamanzi kwezinto zendabuko futhi kuthuthukise ukumelana kwamanzi nokumelana ne-solvent yefilimu yepende.
Ukuqinisa uhlelo lokwelapha
Ngokuvamile, i-Waterborne UV coatings inzima ukuyelapha, ikakhulukazi uma isetshenziswa ezinhlelweni ezinemibala noma izimbotshana eziwugqinsi.Ngaphezu kwalokho, ngenxa yokwengezwa kwe-photoinitiator, i-Waterborne UV coating kulula ukuyelapha ngaphansi kwemisebe ye-ultraviolet.Nokho, lapho ukunamathela kusetshenziswa emishinini eyinkimbinkimbi ngokwengeziwe, imisebe ye-ultraviolet esembozweni se-UV ye-Waterborne ayiphelele, okwenza kube nzima ukuyelapha.Ngakho-ke, ngokwesimo samanje, abacwaningi baye basungula uhlelo lokuphulukisa olunezingqimba eziningi lwezingubo ze-Waterborne UV, ezixazulula ngokuphumelelayo ukulinganiselwa kwe-Waterborne UV coatings futhi andisa uhla lwezicelo lwezingubo.
Ukusebenzisa i-hyperexpenditure system
Ngenxa yokuthi kunamaqembu amaningi e-carboxyl ku-Waterborne UV enamathela, isisindo samangqamuzana aleli qembu sikhulu.Ngakho-ke, i-viscosity ye-Waterborne UV yokugqoka i-UV ikhulu kakhulu, okunciphisa okuqukethwe okuqinile kwe-coating, okunomthelela omubi kwifilimu yepende futhi kunciphisa ukucwebezela nokuphikiswa kwamanzi kwefilimu yopende.Ngakho-ke, ukuze kuthuthukiswe lesi simo, abacwaningi baye basungula uhlelo lwe-hyperbranched e-Waterborne UV coatings, bathuthukisa ukumelana kwamanzi kwefilimu kapende ngokusebenzisa amaqembu amakhulu asebenzayo, futhi basebenzisa izici zesakhiwo sama-oligomers ukunciphisa i-viscosity yesistimu futhi bathuthukise isicwebezelisi sefilimu kapende.
Ukufingqa, ngenxa yobuningi bezinto ezihlanganisiwe ze-Waterborne UV zokunamathisela, inezinzuzo eziyingqayizivele uma iqhathaniswa nezingubo zendabuko.Ngakho-ke, i-Waterborne UV coatings isetshenziswa kabanzi ku-varnish yokhuni nephepha.Ngenxa yokuthuthukiswa okungaphelele kwezingubo ze-Waterborne UV, abacwaningi basathuthukisa ukusebenza kwezingubo ze-Waterborne UV, bengeza amaqembu asebenzayo kuma-coatings futhi basungula uhlelo lokuphulukisa olunezingqimba eziningi.Ngaphezu kwalokho, Ukusetshenziswa kwesistimu ye-hyperbranched ekugqokeni kuyisiqondiso socwaningo lwesikhathi esizayo se-Waterborne UV coatings.Ngokuthuthuka okuqhubekayo kwezingubo ze-Waterborne UV, zingaba nobuthi obuphansi, ubulukhuni obukhulu kanye nesicwebezelisi esiphelele kakhulu.
