Ukuphuculwa kwe-resin yokunyanga ye-UV ye-Waterborne iyeza

I-UV luhlobo oluthile lokugquma olukwazi ukunyanga ngokukhawuleza kwifilimu ngemizuzwana embalwa phantsi kokukhanya kwe-ultraviolet (UV).Ukugquma kweUV kuqengqeleka ngokuzenzekelayo kwaye kutshizwe kwibhodi yefenitshala ngoomatshini kunye nezixhobo.Ngaphantsi kwe-irradiation yokukhanya kwe-ultraviolet, ikhuthaza ukubola komqalisi, ivelise i-radicals yamahhala, ibangele ukusabela kwe-resin, kwaye ngokukhawuleza iqiniswe kwifilimu ngaphandle kwe-solvent volatilization.Ngoko ke, iyasebenza ngakumbi, iluhlaza kunye nokusingqongileyo.

Ngaphantsi kwendlela eqhelekileyo ye-hydration, iingubo ze-UV ze-Waterborne zisetyenziswa ngempumelelo kwiiplanga, iplastiki, ukuprinta, iikhemikhali zemihla ngemihla kunye nezinye iindawo ngenxa yobuhlobo babo bokusingqongileyo kunye nobuhlobo bokwakha.Imathiriyeli ekrwada idlala indima ebalulekileyo.Ukuhlaziywa okuqhubekayo kokusebenza, iimpawu kunye nezisombululo zokusetyenziswa kweengubo zamanzi zikhuthaza inkqubo ye-resin hydration.

I-1 epoxy acrylate / i-polyurethane acrylate inkqubo ehlanganisiweyo

I-oligomer ye-photosensitive yeyona ndawo iphambili ye-resin ephilileyo ye-UV, emisela iimpawu ezisisiseko ze-resin ephilileyo.Zonke iintlobo zeereyini ze-matrix zinezibonelelo zazo ezingenakubuyiselwa, kodwa ngokuqinisekileyo ziya kuba neziphene.Umzekelo, ifilimu ye-epoxy resin ephilisayo inobulukhuni obuphezulu, incamathele kakuhle, isicwebezelisi esiphakamileyo kunye nokumelana neekhemikhali okugqwesileyo, kodwa inesiphene sokungaguquguquki kakuhle.Omnye umzekelo kukuba i-polyurethane esekelwe kwi-resin ineempawu ezintle ezifana nokumelana nokunxiba kunye nokumelana nokuqala, kodwa ukuxhathisa kwayo kwemozulu akwanelanga.Abaphandi basebenzisa iindlela zokudibanisa okanye ezixubileyo ukudibanisa ezi zimbini, ukuze benze ukusilela kwe-resin enye kunye nokuphuhlisa inkqubo eneempawu ezibalaseleyo zombini.

I-2 dendritic okanye inkqubo ye-hyperbranched

Ii-dendrimers ezinyangekayo ze-UV ezifumaneka emanzini okanye ii-oligomers ezine-hyperbranched luhlobo olutsha lwee-polymers ezinokwakheka kwe-spherical okanye i-dendritic kwaye akukho nto ibambekayo phakathi kwamakhonkco emolekyuli.Ngaphezu koko, isakhiwo se-polymer ene-branched iqulethe inani elikhulu lamaqela okugqibela asebenzayo.La maqela okugqibela asebenzayo aguqulwa ukulungelelanisa iimpawu zepolymer kwaye ayisebenzise kwiindawo ezithile.Xa kuthelekiswa neepolymers ezihambelanayo ezinobunzima obufanayo bemolekyuli, i-oligomers ene-hyperbranched ineempawu ezibalaseleyo njengendawo yokunyibilika ephantsi, i-viscosity ephantsi, ukunyibilika ngokulula kunye nokusebenza kwakhona okuphezulu.Zizinto ezifanelekileyo zokukhanya kwamanzi okuphilisa i-matrix resins.I-polyester ye-hyperbranched yamanzi eyenziwe nge-polyhydroxy esebenzayo ye-aliphatic polyester njengoko ingundoqo inokunciphisa amanzi adibeneyo kwaye ibonise umphumo omuhle wokunciphisa i-viscosity ngenxa yokunyibilika kwayo kakuhle kwamanzi kunye ne-viscosity ephantsi.

I-3 epoxy yeembotyi zesoya iacrylate

I-oyile ye-soya ye-epoxy ineenzuzo zexabiso eliphantsi, ukukhuselwa kwendalo, i-molecular chain chain kunye ne-moderate crosslinking density.Inokuphucula kakhulu ukuguquguquka kunye nokunamathela kwengubo.Kwiminyaka yakutshanje, iye yaba yindawo yophando kwinkalo yeengubo ekhaya nakwamanye amazwe.Ufezekiso olulungileyo lwenziwe kwi-epoxy ye-oyile yeembotyi zesoya kunye ne-epoxy ye-oyile yesoya elungisiweyo i-acrylate ye-UV yasimahla yokunyanga i-radical e-China.Inkampani yaseCub e-United States yenze imveliso yorhwebo, efana ne-ebercy860.Indlela yokudityaniswa kwe-epoxy ye-oyile yeembotyi zesoya ngokuqhelekileyo yindlela yokuguqulwa kwe-semi-ester, eku-esterificate i-oyile ye-epoxy yeembotyi zesoya nge-acrylic acid.
