I-resin ye-UViyingxenye eyinhloko yesistimu yokwelapha ye-UV.Kuyi-oligomer engabhekana nezinguquko zomzimba namakhemikhali esikhathini esifushane ngemva kokuvezwa ukukhanya kwe-UV, futhi ixhumane ngokushesha futhi zelaphe.Ngemuva kokwelashwa kwe-UV enamathelayo, ukusebenza okuyisisekelo kwefilimu yokumboza kuncike kakhulu ezintweni zayo eziyinhloko zokwakha ifilimu - i-UV resin, kanye nokusebenza kwefilimu.I-resin ye-UVkunqunywa i-polymer ye-macromolecular eyakha le resin.Isakhiwo samangqamuzana, isisindo samangqamuzana, ukuminyana kwebhondi ephindwe kabili kanye nezinga lokushisa lokushintsha kwengilazi ye-polymer kuzothinta ukusebenza kwe-resin.I-resin ye-UV enamafutha yendabuko inesisindo esikhulu samangqamuzana kanye ne-viscosity, ngakho inokushiyeka enqubweni yokumboza nokulawula ukusebenza kwefilimu.I-Acrylatei-diluent esebenzayo [1] iqukethe amabhondi amabili angagcwalisiwe futhi ine-viscosity ephansi.Ukuyengeza ohlelweni lokwelapha lwe-UV kunganciphisa i-resin viscosity, kuthuthukise ukuminyana kokuxhumanisa kwe-resin, futhi kuthuthukise ukusebenza kwefilimu ye-resin, ngakho-ke isetshenziswa kabanzi.Kodwa-ke, ama-diluent amaningi asebenzayo anobuthi futhi ayacasula isikhumba somuntu, ulwelwesi lwamafinyila namehlo.Ngaphezu kwalokho, i-diluent kunzima ukusabela ngayo ngokuphelele ngesikhathi sokukhanya kwe-UV, futhi i-monomer esele izothinta ngokuqondile ukusebenza kwesikhathi eside kwefilimu ephulukisayo, ebeka umkhawulo ekusetshenzisweni kwayo ekupakisheni izinto zemikhiqizo yokuhlanzeka kokudla.
AmanziI-resin ye-UVibhekisela kuI-resin ye-UVencibilika emanzini noma engahlakazwa ngamanzi.Ama-molecule ayo aqukethe inani elithile lamaqembu e-hydrophilic afana ne-carboxyl, i-hydroxyl, i-amino, i-ether noma amaqembu e-amide, kanye namaqembu angasetshenzisiwe afana ne-acryloyl, i-methacryloyl noma amaqembu e-alyl.Okwamanje, amanziAma-resin e-UVikakhulukazi ihlanganisa i-polyacrylate yamanzi, i-polyester acrylate yamanzi, i-epoxy acrylate yamanzi kanye ne-polyurethane acrylate yamanzi.
Njengohlobo olusha lwe-polymer, i-hyperbranched polymer inesakhiwo esiyindilinga, inani elikhulu lamaqembu wokugcina asebenzayo, futhi akukho ukugoqa phakathi kwamaketanga amangqamuzana.Ama-polymers ane-hyperbranched anezinzuzo zokuhlakazeka kalula, indawo encibilikayo ephansi, i-viscosity ephansi kanye nokusebenza kabusha okuphezulu.Ngakho-ke, amaqembu e-acryloyl namaqembu e-hydrophilic angasungulwa ukuze ahlanganise ama-oligomers e-UV alaphekayo atholakala emanzini, okuvula indlela entsha yokulungiswa kwamanzi.Ama-resin e-UV.
