Iingubo ze-UV eziphuma emanzini ikakhulu zibandakanya i-resin ze-UV eziphuma ngaManzi, ii-photoinitiators, izongezo kunye nokufakwa kwemibala.Phakathi kwawo onke amacandelo, i-resin ye-UV ye-Waterborne inempembelelo enkulu ekusebenzeni kwe-UV ye-Waterborne.Ukusebenza kwe-resin ye-UV ye-Waterborne ichaphazela amandla, ukuxhathisa ukubola kunye nokunyanga ubuntununtunu befilimu ephilisiweyo kumphezulu wengubo [1].I-resin esekelwe emanzini nayo ichaphazeleka yi-photoinitiator.Ngaphantsi kwempembelelo ye-photoinitiator, i-resin esekelwe emanzini inokunyangwa phantsi kokukhanya.Ke ngoko, i-photoinitiator nayo iyinxalenye ebalulekileyo yeengubo ze-UV eziphuma emanzini.Imfuno yophuhliso lwexesha elizayo yefotonitiator i-polymerizable kunye ne-macromolecular.
Izinto eziluncedo zokugquma kwe-UV ye-Waterborne: i-viscosity ye-coatings inokulungelelaniswa ngaphandle kokudibanisa i-monomers, ukuphelisa ubuthi kunye nokucaphuka kweengubo zendabuko.Izongezo ze-Rheological zinokongezwa ngokufanelekileyo ukunciphisa i-viscosity yenkqubo yokugqoka, elungele inkqubo yokugqoka.Xa i-coating yenziwe ngeplastiki kunye nezinye izinto, amanzi angasetyenziselwa njenge-diluent ukuphucula ukunamathela phakathi kwengubo kunye nokugqoka.Iphucula amandla obungqina bothuli kunye nobungqina bokukrwela ngaphambi kokunyanga, iphucula ukugqitywa kwengubo, kwaye ifilimu ephilisiwe i-ultra-thin.Izixhobo zokugquma kulula ukuzicoca.Iingubo ze-UVB ezisemanzini zinokubuyiswa kakuhle komlilo.Ekubeni i-low molecular active diluent isetyenzisiweyo, ukuguquguquka kunye nokuqina kunokuqwalaselwa.
Iingubo ze-resin ze-UV ezinamanzi zinokudityaniswa kwaye ziphiliswe ngokukhawuleza phantsi kwesenzo se-photoinitiator kunye nokukhanya kwe-ultraviolet.Inzuzo enkulu ye-resin ephuma emanzini yi-viscosity elawulwayo, ukucoceka, ukukhuselwa kwendalo, ukonga amandla kunye nokusebenza okuphezulu, kunye nesakhiwo sekhemikhali se-prepolymer sinokuyilwa ngokweemfuno zangempela.Nangona kunjalo, kusekho ukusilela kule nkqubo, njengokuzinza kwexesha elide lenkqubo yokusasazwa kwamanzi okugquma kufuneka kuphuculwe, kwaye ukufunxwa kwamanzi kwifilimu ephilisiwe kufuneka kuphuculwe.Abanye abaphengululi bachaza ukuba kwixesha elizayo, iteknoloji yokunyanga ukukhanya kwamanzi iya kuphuhlisa kule miba ilandelayo.
(1) Ukulungiswa kwama-oligomers amatsha: kubandakanywa i-viscosity ephantsi, umsebenzi ophezulu, umxholo ophezulu oqinileyo, i-multifunctional kunye ne-hyperbranched.
(2) Phuhlisa ama-diluents amatsha asebenzayo: kubandakanywa i-acrylate entsha esebenzayo, enokuguqulwa okuphezulu, i-reactivity ephezulu kunye nokunciphisa umthamo ophantsi.
(3) Uphando kwiinkqubo ezintsha zokunyanga: ukuze woyise iziphene zokunyanga okungaphelelanga ngamanye amaxesha okubangelwa kukungangeni kwe-UV, iinkqubo ezimbini zokunyanga zamkelwa, ezinje ngokukhanya kweradical free / cationic light curing, free radical light curing, thermal mpiliso, Ukunyangwa kokukhanya kwasimahla / ukunyangwa kwe-anaerobic, ukunyangwa kokukhanya simahla / ukunyanga okumanzi, ukuphilisa ukukhanya okusimahla / ukunyanga i-redox, ukuze udlale ngokupheleleyo kwintsebenziswano phakathi kwezi zimbini, Ukukhuthaza uphuhliso olungaphaya lwecandelo lesicelo sezinto zokunyanga ukukhanya kwamanzi. .
