Ukwelapha okukabili ubuchwepheshe obusha, obuhlanganisa izinzuzo zokuphulukisa okushisayo okujwayelekile kanye nezinhlelo zokuphulukisa ze-UV.Inganikeza ukumelana okuhle nokuklwebheka kanye nokumelana namakhemikhali kwezingubo ze-UV, kuyilapho ivumela ukuphulukiswa kwesithunzi ngokusabela okushisayo.Lesi sici senza ukuphulukiswa okukabili kube ukukhetha okukhangayo kwezinhlelo zokusebenza zangaphakathi zezimoto.Ukuguquguquka kwenqubo yayo futhi kuvumela ofake isicelo ukuthi alungise futhi aguqule umugqa wokukhiqiza okhona ngaphandle kokwakha kusukela ekuqaleni.
Njengoba incazelo engaphezulu yegama elithi “ukwelapha kabili” iveza, lobu buchwepheshe buyinhlanganisela yokwelapha kwe-UV kanye nokwelapha ukushisa.izinhlaka.I-UV acrylate monomer ne-oligomer, i-photoinitiator,i-acrylic resinfuthi i-solvent yakha ukwakheka okuyisisekelo.Amanye ama-resin aguquliwe kanye nezithasiselo nawo angafakwa kufomula.Inhlanganisela yalezi zinto zokusetshenziswa kwakha uhlelo olunokunamathela okuhle kuma-substrates amaningi, kuyilapho ihlinzeka ngobulukhuni bobuso obungenakulinganiswa, ukumelana nokuklwebheka kanye nokumelana nokugqoka.
I-matrix yokuhlola yezingubo ezimbili zokuphulukisa ngokuvamile ihlukaniswe ngezigaba ezine: ukunamathela, ukumelana nokuklwebheka, ukumelana namakhemikhali kanye nokumelana nesimo sezulu.I-coating yokwelapha ukushisa ingaba nesici "sokuziphilisa", futhi ukuhuzuka kwendawo kanye ne-scratch ekugcineni kuzonyamalala ngenxa yokuguquguquka kwe-resin.Nakuba lokhu kuyisici esivumayo kusukela ekuqaleni kokubuka, futhi kwenza ukunamathela kube sengozini kuma-ejenti amakhemikhali ahlukahlukene.Ukumbozwa kwe-UV ngokuvamile kunezinga eliphezulu lokuxhumanisa indawo ephambanayo, okubonisa ukuqina okuhle kakhulu kokuklwebheka, kodwa ukunamathela kuntekenteke futhi kulula ukukhiqiza izinkinga zokunamathela nesimo sezulu.
Kunezidingo ezimbili kuphela zokucutshungulwa kokugcotshwa okuphindwe kabili: kuhhavini wokwelapha okushisayo kanye nesibani se-ultraviolet sokwelapha i-acrylate.Lokhu kwenza i-coater iguqule ulayini wokukhiqiza upende okhona ngaphandle kokwakha umugqa omusha wokukhiqiza upende.
Esinye sezithiyo ezinkulu zobuchwepheshe bokuphulukisa okukabili ukukhawulelwa kokuxuba imibala.Amasistimu amaningi okuphulukisa ama-UV asobala noma anombala okhanyayo, ngoba umbala uzophazamisa ukuphulukiswa kwe-UV.Ama-pigments, i-pearl powder kanye nama-flakes ensimbi kungavimbela ukuphulukiswa ngokusakaza imisebe ye-ultraviolet nokuvimbela imisebe eyanele ye-ultraviolet ukuthi ingangeni ku-coating (Umfanekiso 3).Umphumela uwukwakheka kwe-acrylate engaphulukisiwe eduze kwesixhumi esibonakalayo se-substrate.Ukuphakama kwe-coating yalezi zingubo ezinemibala, kubi kakhulu ukuphulukiswa.
