Ukuhlelwa okuLula kweeResins ze-UV

I-resin ye-UV, eyaziwa ngokuba yi-photosensitive resin, yi-oligomer enokuthi itshintshe umzimba kunye neekhemikhali ngexesha elifutshane emva kokuvezwa ekukhanyeni, kwaye emva koko i-crosslink kwaye iqiniswe.I-resin ye-UV yohlulwe ikakhulu kwi-solvent based UV resin kunye ne-resin ye-UV esekwe emanzini.

I-solvent esekelwe kwi-resin ye-UV

I-solvents eziqhelekileyo ezisekelwe kwi-resin ze-UV ikakhulu ziquka: i-UV unsaturated polyester, i-UV epoxy acrylate, i-UV polyurethane acrylate, i-UV polyester acrylate, i-UV polyether acrylate, i-UV ecocekileyo ye-acrylic resin, i-UV epoxy resin, i-silicone oligomer ye-UV, njl.

I-resin ye-UV ephuma emanzini

I-resin ye-UV ephuma emanzini ibhekiselele kwi-resin ye-UV enyibilikayo emanzini okanye enokuthi isasazwe ngamanzi.I-molecule iqulethe inani elithile lamaqela anamandla e-hydrophilic, njenge-carboxyl, i-hydroxyl, i-amino, i-ether, kunye namaqela e-acylamine;Kwakhona iqulethe amaqela angaxutywanga, afana ne-acryloyl, i-methacryloyl okanye amaqela e-allyl.Imithi ye-UV efumaneka emanzini inokohlulwa ibe ngamacandelo amathathu: i-lotion, amanzi anokuchithwa kunye ne-soluble emanzini, ngokukodwa kuquka iindidi ezintathu: i-polyurethane acrylate yamanzi, i-epoxy acrylate yamanzi kunye ne-polyester acrylate yamanzi.

I-resin ye-UV ephuma emanzini ngokubanzi iqulethe i-80-90% ye-resin yamanzi kunye ne-10-20% yezinye izongezo.Emva kokugquma kunye nokupholisha, umaleko obhityileyo owenziwe ngepolymer ushiywe kumphezulu we-substrate, onika ukwambathisa ngeempawu ezahlukeneyo ngenxa yokudityaniswa kwefomula eyahlukileyo.Njengeglosi ephezulu, i-matt, i-abrasion resistant, njl.

I-resin yasemanzini yeyona nto iphambili ye-Z kwi-resin ye-UV ephuma emanzini.Imisela kwaye ichaphazela iipropati ze-resin ye-UV eziphuma emanzini, ezifana ne-luster, i-adhesion, ukuxhathisa i-abrasion, ukoma, njl. Ngoko ke, ukhetho olufanelekileyo lwe-resin ye-UV ephuma emanzini ngundoqo ekuhanjisweni ngempumelelo kwe-resin ye-UV ephuma emanzini.

Kukho iintlobo ezininzi zeerasi, kubandakanywa i-rosin yamanzi eguqulwe i-resin maleic, i-waterborne polyurethane resin, i-waterborne acrylic resin, i-alkyd resin ephuma emanzini, i-amino resin ephuma emanzini, njl. ukukhutshwa kwamanzi, i-gloss enhle emva kokubunjwa kwefilimu, ukumelana nobushushu, ukuchasana kweekhemikhali, isantya sokumisa ngokukhawuleza, njl., ngelixa i-acrylic copolymer resin yamanzi inokuhlangabezana neemfuno zokuprinta kunye ne-glazing kumlinganiselo omkhulu.Ke ngoko, xa ulungiselela i-resin ye-UV ephuma emanzini, inkqubo ye-acrylic copolymer yamanzi iba lolona khetho lwethu lulungileyo.

I-aqueous acrylic copolymer resin inokohlulwa ibe yi-aqueous acrylic resin solution, i-aqueous acrylic dispersion, kunye ne-acrylic lotion.I-Acrylic lotion inokohlulwa ibe yifilim-forming acrylic lotion kunye nenonfilm-forming acrylic lotion.Iimpawu ze-acrylic copolymer resin zamanzi zenziwe ngama-monomers.Inkqubo yokusebenza kunye nokudibanisa.Ezinye ii-monomers zinokuphucula i-luster kunye nobunzima, ngelixa ezinye zinokubonelela ngokumelana neekhemikhali kunye nokubambelela.Uninzi lweemvavanyo lubonakalise ukuba i-resin ye-UV esemanzini, edityaniswe ngokwesayensi kunye nesisombululo se-aqueous acrylic acid kunye ne-acrylic acid lotion, ineempawu ezifanelekileyo.
