I-resin ye-UVlelona candelo liphambili le-UV yokunyanga inkqubo.I-oligomer enokuthi itshintshe umzimba kunye neekhemikhali ngexesha elifutshane emva kokuvezwa kukukhanya kwe-UV, kwaye ngokukhawuleza ukuwela kunye nokunyanga.Emva kokunyangwa kwengubo ye-UV, ukusebenza okusisiseko kwefilimu yokwambathisa kuxhomekeke kakhulu kwinto ephambili yokwenza ifilimu-i-resin ye-UV, kunye nokusebenza kwefilimu.I-resin ye-UVigqitywe yipolymer macromolecular eyenza le resin.Ubume bemolekyuli, ubunzima bemolekyuli, ukuxinana kwebhondi ephindwe kabini kunye nobushushu beglasi yokutshintsha kwepolymer kuya kuchaphazela ukusebenza kwe-resin.I-resin ye-oyile ye-UV yendabuko inobunzima obukhulu be-molecular kunye ne-viscosity, ngoko ineziphene kwinkqubo yokugquma kunye nokulawula ukusebenza kwefilimu.I-AcrylateI-diluent esebenzayo [1] iqulethe iibhondi ezimbini ezingaxutywanga kwaye ine-viscosity ephantsi.Ukuyongeza kwinkqubo yokunyanga ye-UV kunokunciphisa i-resin viscosity, ukuphucula ukuxinana kokudibanisa kwe-resin, kunye nokuphucula ukusebenza kwefilimu ye-resin, ngoko isetyenziswa ngokubanzi.Nangona kunjalo, uninzi lwe-diluents olusebenzayo luyityhefu kwaye luyacaphukisa ulusu lomntu, i-mucous membrane kunye namehlo.Ukongeza, i-diluent inzima ukusabela ngokupheleleyo ngexesha lokukhanya kwe-UV, kwaye i-monomer eseleyo iya kuchaphazela ngokuthe ngqo ukusebenza kwexesha elide lefilimu yokunyanga, ethintela ukusetyenziswa kwayo kwizinto zokupakisha iimveliso zokucoceka kokutya.
AmanziI-resin ye-UVibhekisa kwiI-resin ye-UVenyibilikayo emanzini okanye enokuthi isasazwe ngamanzi.Iimolekyuli zayo ziqulethe inani elithile lamaqela e-hydrophilic afana ne-carboxyl, i-hydroxyl, i-amino, i-ether okanye amaqela e-amide, kunye namaqela angaxutywanga afana ne-acryloyl, i-methacryloyl okanye amaqela e-alyl.Okwangoku, amanziIirensi ze-UVikakhulu ibandakanya i-waterborne polyacrylate, i-waterborne polyester acrylate, i-waterborne epoxy acrylate kunye ne-waterborne polyurethane acrylate.
Njengohlobo olutsha lwepolymer, i-hyperbranched polymer inesakhiwo se-spherical, inani elikhulu lamaqela okugqibela asebenzayo, kwaye akukho kuphonswa phakathi kwamakhonkco e-molecular.I-Hyperbranched polymers ineenzuzo zokuchithwa lula, indawo encibilikayo ephantsi, i-viscosity ephantsi kunye nokusebenza okuphezulu.Ke ngoko, amaqela e-acryloyl kunye namaqela e-hydrophilic anokwaziswa ukuze adibanise i-oligomers enyangekayo ye-UV, evula indlela entsha yokulungiswa kwamanzi.Iirensi ze-UV.
