Izingubo ze-UV ezisekelwe emanzini zingaxhunywa ngokushesha futhi zelashwe ngaphansi kwesenzo sama-photoinitiators nokukhanya kwe-ultraviolet. Inzuzo enkulu yama-resin asekelwe emanzini ukuthi i-viscosity iyalawuleka, ihlanzekile, ihambisana nemvelo, 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 zabonisa 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 ze-acrylate, ezinezinga eliphezulu lokuguqulwa, ukuphinda kusebenze 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, i-photocuring ye-radical yamahhala, ukuphulukiswa okushisayo, ukuthwebula izithombe nge-radical mahhala, kanye ne-free radical photocuring. Ngokusekelwe ekwelapheni izithombe/i-anaerobic, ukuphulukiswa kwezithombe nge-radical yamahhala/ukwelapha umswakama, ukuphulukiswa kwezithombe nge-radical mahhala/ukwelashwa kabusha kwe-redox, njll., umthelela we-synergistic walokhu okubili ungenziwa ngokugcwele, okuthuthukisa ukuthuthuka okuqhubekayo kwenkundla yokusetshenziswa kwezinto ezitholakala emanzini
