Izembatho ze-UV ezitholakala emanzini zingaxhunywa ngokushesha futhi zelashwe ngaphansi kwesenzo sama-photoinitiators nokukhanya kwe-ultraviolet.Inzuzo enkulu yama-resin asekelwe emanzini ukuthi i-viscosity iyalawuleka, ihlanzekile, imvelo, igcina amandla futhi isebenza kahle, futhi isakhiwo samakhemikhali se-prepolymer singaklanywa ngokuvumelana nezidingo zangempela.Kodwa-ke, lolu hlelo lusenamaphutha, njengokuzinza kwesikhathi eside kwesistimu yokusabalalisa amanzi okunamathela kufanele kuthuthukiswe, futhi ukumuncwa kwamanzi kwefilimu ephulukisiwe kudinga ukuthuthukiswa.Ezinye izazi ziye zaveza ukuthi ubuchwepheshe bokuphulukisa ukukhanya okusekelwe emanzini esikhathini esizayo buzothuthuka kulezi zici ezilandelayo.
(1) Ukulungiswa kwama-oligomers amasha: kufaka phakathi i-viscosity ephansi, umsebenzi ophezulu, okuqukethwe okuqinile okuphezulu, ukusebenza okuningi kanye ne-hyperbranching.
(2) Dala ama-diluent amasha asebenzayo: kufaka phakathi izihlambululi ezintsha ezisebenzayo ze-acrylate, ezinezinga eliphezulu lokuguqulwa, ukusebenza kabusha okuphezulu kanye nokuncipha kwevolumu ephansi.
(3) Ucwaningo ngezinhlelo ezintsha zokwelapha: Ukuze kunqotshwe izinkinga zokuphulukiswa okungaphelele ngezinye izikhathi okubangelwa ukungena okulinganiselwe kokukhanya kwe-UV, kusetshenziswa amasistimu okuphulukisa akabili, njengokuthwebula kwamahhala kwe-radical/cationic photocuring, ukuthwebula ama-radical mahhala, ukuphulukiswa okushisayo, i-radical yamahhala. photocuring, kanye free radical photocuring.Ngokusekelwe ekwelapheni kwe-photocuring/anaerobic, ukuphulukiswa kwezithombe nge-radical mahhala/ukwelashwa komswakama, ukuphulukiswa kwe-radical mahhala/ukwelashwa kabusha kwe-redox, njll., umthelela we-synergistic wakho kokubili ungenziwa ngokugcwele, okukhuthaza ukuthuthukiswa okuqhubekayo kwenkundla yokusetshenziswa kwezinto ezitholakala emanzini.
