I-resin ye-UV, ekwabizwa ngokuba yi-oligomer ye-UV, yinto ebalulekileyo eyenza ifilimu ye-UV Z. phantsi kwemeko yokukhanya kwe-UV, idityaniswe kwizakhiwo zothungelwano ezinoxinano olwahlukeneyo ngokusebenza kweemolekyuli ze-photoinitiator, ukuze i-UV yokwaleka ibe neentlobo ezahlukeneyo. Iimpawu zomzimba nezoomatshini, ezinje ngobulukhuni obuphezulu, ukuthamba okuphezulu, ukuncamathela okungcono kwe-substrate, ipropathi ephantsi emthubi, ukumelana nemozulu ephezulu, njl.
I-oligomers ye-UV esetyenziswa ngokuqhelekileyo yahlula kwisakhiwo se-molecular.Sinokuzishwankathela zibe: i-epoxy acrylate oligomer, i-polyurethane acrylate oligomer, i-amino acrylate oligomer, i-polyester acrylate oligomer, i-oligomer ecocekileyo ye-acrylate kunye nezinye ii-oligomers ze-acrylate ezinesakhiwo esikhethekileyo.Ngokusebenzisa umgaqo wolwahlulo lwesakhiwo, sichaza ithiyori kwaye sichaze ngokufutshane ukusebenza kwemveliso ye-oligomer ye-UV esetyenziswa ngokuqhelekileyo, sifumane isiseko sethiyori ukuxhasa ukusebenza kwabo, kunye nokuqinisa ukuqonda kweemveliso ezinxulumeneyo.
Kufuneka kucaciswe ukuba ii-oligomers ze-UV zinokwahlulwa zibe ziimveliso ezahlukeneyo ezinedigri ezisebenzayo ezahlukeneyo kudidi olufanayo lolwakhiwo.Ngenani elihlukeneyo lamaqela asebenzayo, ukudibanisa kwesakhiwo sothungelwano olwenziweyo kuya kuhambelana.Amaqela asebenzayo abhekisa kumaqela asebenzayo kwi-resin anokungena kwi-cross-linking reaction.Amaqela asebenzayo ngakumbi kwi-molecule enye, i-denser ifilimu eyenziwe emva kokunyanga, kwaye kulula ukufumana ifilimu yepeyinti ngobunzima obuphezulu.Nangona kunjalo, ngexesha elifanayo, ngenxa yokwanda kwenani lamaqela adibanisa umnqamlezo, amandla e-shrinkage eyenziwa kwinkqubo yokuphulukisa i-oligomer nayo iya kwanda, oku kuya kukhokelela ngokulula ekuthinteleni ukukhutshwa koxinzelelo okanye ukuncipha kokubambelela ngexesha. inkqubo yokomisa yokwaleka.Emva kokumisela iipropati ezibanzi zokugquma, i-UV ye-UV ye-coating formulator kufuneka ikhethe iimveliso ezifanelekileyo zokudibanisa ngokweepropati ze-oligomer zezakhiwo ezahlukeneyo kunye namaqela asebenzayo, ukuze ufumane i-coating kunye nokusebenza okulinganayo kunye nokugqiba uyilo lwe-UV ye-coating formula. .
Ukuba i-viscosity ye-resin ye-UV iphezulu kakhulu, ayifanelekanga ukongeza kakhulu kwezinye iindawo zesicelo ezifuna iglue ye-UV enomanzi kakuhle.Isalathisi se-refractive se-resin siphantsi kakhulu.Kwinqanaba lokusetyenziswa kwe-lens optical, ukuhanjiswa kokukhanya akwanelanga, ngoko ke ayisetyenziswanga njengesalathiso.Ngokuphathelele amandla e-viscosity, i-resin equkethe-Oh ngokubanzi inonamathele kakuhle kwiglasi, ngoko andiyi kuyichaza kakhulu apha.I-resin ye-UV yiresin ye-matrix yeglue ye-UV.Idityaniswe kunye ne-photoinitiator, i-diluent esebenzayo kunye neentlobo ezahlukeneyo zokudibanisa ukwenza iglue ye-UV.Kwinqanaba le-synthesis, iinkqubo ezahlukeneyo ze-synthesis okanye ukukhethwa kwee-monomers kubangela ukungaqiniseki kwe-resin.I-viscosity, i-refractive index kunye nokusebenza kwe-resin kwizinto ezahlukeneyo kufuneka ziqwalaselwe.
Ezona ndawo ziphambili zokusetyenziswa kweresin ye-UV: i-UV inki, iglue ye-UV, njl.njl. phakathi kwazo, i-Z isetyenziswa ngokubanzi kwi-UV yokugquma, kubandakanya ezi ntlobo zilandelayo ze-UV esekelwe emanzini, i-UV powder, i-UV yesikhumba, i-UV. I-optical fibre coating, i-UV yentsimbi yokugquma, i-UV yokuhombisa iphepha, i-UV yeplastiki yokugquma kunye ne-UV yomthi.
Izinto ezilungileyo ze-UV resin photosensitive resin yinto endala kunye nentsha.Xa kuthelekiswa nezinto zokunyanga ngokubanzi, izinto zokunyanga ukukhanya zineenzuzo ezilandelayo: ukunyanga ngokukhawuleza, ukunyanga ngemizuzwana embalwa, kwaye inokusetyenziswa kwiimeko ezifuna ukunyangwa ngokukhawuleza.Iimveliso zasimahla zokunyibilikisa zinokulungiswa ngaphandle kokufudumeza.Ukusetyenziswa kwezinyibilikisi kuya kubandakanya iingxaki ezininzi zokusingqongileyo kunye neenkqubo zokuvunywa.Ngoko ke, onke amacandelo amashishini azama ukunciphisa ukusetyenziswa kwe-solvents.Oku kuluncedo kakhulu kwezinye iiplastiki ezinganyangekiyo kubushushu, iindawo zamehlo neze-elektroniki;Inokuqonda ukusebenza okuzenzekelayo kunye nokuqina, ukuphucula iqondo lokuzenzekelayo kwimveliso, ukuze kuphuculwe ukusebenza kakuhle kwemveliso kunye neenzuzo zoqoqosho.I-resin ye-photosensitive isetyenziswa kushishino olusakhulayo loshicilelo lwe-3D, oluthandwa kwaye luxatyiswe lishishini ngenxa yeempawu zalo ezintle.I-resin yokuqala ye-Kaft ye-photosensitive e-China isetyenziswa njengezinto ezisetyenziswayo zoshicilelo ze-3D, ezilungele ukukhanya okuphezulu okunyanga i-3D yoshicilelo kunye nenkqubo ye-prototyping ye-SLA ekhawulezayo.
