I-Gelation isho ukujiya noma ukugoqa kweresin ye-UV noma ukunamathela ezingeni lokushisa elishiwo nesikhathi.
Izizathu eziyinhloko ze-gelatinization ye-UV resin noma ukunamathela yilezi ezilandelayo:
1. Ngalé kwesikhathi seshalofu, isikhathi seshalofu se-UV resin ngaphansi kwezimo ezinhle zokulondolozwa akufanele sidlule izinyanga eziyisithupha.Kodwa i-Z enhle ingasetshenziswa ezinyangeni ezintathu.
2. I-UV resin kufanele igcinwe emiphongolweni yepulasitiki noma emiphongolweni yensimbi eboshwe ngepulasitiki.Ama-ion ensimbi azonciphisa amandla okuvula amabhondi aphindwe kabili ku-UV resin futhi aqalise i-polymerization, okuholela ekufakweni kwe-resin.Ngakho-ke, uma ungqimba lwepulasitiki lokunamathisela emgqonyeni wepulasitiki lonakele, ungqimba lwensimbi olungenalutho luzodala i-resin gelation.
3. Izinga lokushisa eliphansi kakhulu lesitoreji (ngaphansi kuka-0 ℃) lizokwengeza isivimbeli se-polymerization efilimini kapende, okuholela ekwenziweni kwe-resin self polymerization kanye ne-resin gelation.
4. I-UV resin kufanele ivikeleke ngokuqinile ekukhanyeni kwelanga ngesikhathi sokugcinwa.Uma kungenjalo, kulula ukubangela i-resin gelation.
5. Uma umgqomo ugcwele kakhulu, ayikho i-oxygen eyanele ukuvimbela i-polymerization, okuzobangela i-resin gelation.
Izinyathelo zokuvimbela i-gelation:
1. I-viscosity ye-resin ngaphandle kwe-diluting monomer iphezulu kakhulu.Abanye abasebenzisi bazocabanga ngephutha ukuthi i-resin ifakwe i-gelatinized.Eqinisweni, kulula ukubona ukuthi i-resin ifakwe i-gelatinized ngemva kokushisa.I-resin ngaphandle kwe-gelatinization izoba ne-fluidity enhle ngemva kokushisa.
2. Ngokuqondene nokusetshenziswa kwe-UV resin, izindlela zokutholwa kanye nezinkomba zefilimu enamathelayo ye-UV ziyafana nalezo zezinye izimbotshana, ezihluka ngokusetshenziswa okuqondile.Kuzoba nezinkinga ezahlukahlukene ekusetshenzisweni kwezingubo ze-UV.I-gelatinization kuphela ngesikhathi sokugcina ihlobene eduze ne-UV resin ngokwayo, futhi ezinye izinkinga zingaxazululwa ngokulungisa ifomula yokugqoka ye-UV.Njengoba i-uvpaint yakhiwe izingxenye ezihlukahlukene, iphinde ithintwa ibanga lokukhanya komthombo wokukhanya nesikhathi sokukhanyisa, futhi ukusebenza kwayo kwefilimu kuwumphumela wesenzo esibanzi sezici ezihlukahlukene.Ukuze uthole ifomula efanayo, shintsha ngokushesha i-resin efanayo.Ngenxa yomehluko wama-resin avela kubakhiqizi abahlukahlukene, ukusebenza kwefilimu kuzoshintshwa, futhi ifomula idinga ukulungiswa.Kodwa-ke, uma nje i-resin ingekho i-gelatinized noma i-gelatinized kupende olungiselelwe, ukusebenza kwefilimu kungalungiswa ngokusebenzisa ifomula.
3. Kunezizathu eziningi ze-gelatinization yepende ye-UV, engahlobene kuphela ne-resin.Okokuqala, kufanele sibheke ukuthi kubangelwa ukugcinwa okungafanele yini.Ngenxa yokwengezwa kwe-photosensitizer embotsheni ye-UV, izimo zayo zokugcina ziqine kakhulu kunalezo ze-UV resin.Kudingeka ukuyibeka ebumnyameni ukuze ugweme ukubona ukukhanya.Okwesibili, i-photosensitizer ekhethiwe ingeyekhwalithi embi, futhi noma igcinwe ebumnyameni, izobola kancane futhi ibangele i-gelation ye-coating ephulukisiwe.
4. Ikhwalithi ye-monomer nayo iyisici esibalulekile esithinta ukuzinza kwesitoreji.
