Upende ungabonakala yonke indawo empilweni yethu, futhi asijwayelene nawo.Mhlawumbe ngenxa yezingubo ezifundwe empilweni, zisekelwe ku-solvent noma i-thermosetting.Kodwa-ke, umkhuba wamanje wokuthuthuka upende we-UV, okuwupende oluhlaza ohambisana nemvelo.
Upende we-UV, owaziwa ngokuthi "upende oluluhlaza olusha futhi oluhambisana nemvelo ekhulwini lama-21", uthuthuka ngenani elingaphezu kokuphindwe kabili ukusetshenziswa konyaka.Ukuvela kopende we-UV kuzokwenza izinguquko zokuzamazama komhlaba kuphethini yokusetshenziswa kwezingubo zendabuko.Uyini upende we-UV?Ukuvela kwayo kuzoba namuphi umthelela omkhulu embonini yokukhiqiza ifenisha?
Uyini upende we-UV?
Upende we-UV ubhekisela kupende we-ultra violet wokwelapha, okuwukuthi, ukufakwa kwe-resin esebenzisa i-UV njengamandla okwelapha futhi ixhumanisa ngokushesha ekamelweni lokushisa.Ukukhanya kwe-Ultraviolet kukhiqizwa amathuluzi akhethekile, futhi inqubo yokuthi into efakwe imisebe ikhiqize ukusabela kwamakhemikhali ngemisebe yokukhanya kwe-UV kanye nokushintsha kusuka oketshezini kuya kokuqinile kubizwa ngokuthi inqubo ye-UV yokwelapha.
Ubuchwepheshe bokwelapha i-UV buwubuchwepheshe bonga amandla, buhlanzekile futhi buhambisana nemvelo.Yonga amandla - ukusetshenziswa kwayo kwamandla kuyingxenye eyodwa kwezinhlanu kuphela zokwelashwa okushisayo.Ayinazo izincibilikisi, inokungcola okuncane endaweni ezungezile, futhi ngeke ikhiphe igesi enobuthi ne-carbon dioxide emkhathini.Kuyaziwa ngokuthi "ubuchwepheshe obuluhlaza".Ubuchwepheshe bokuphulukisa i-UV wuhlobo lobuchwepheshe bokucubungula izithombe olwenza inhlaka ye-epoxy acrylic ewuketshezi yenziwe i-polymerized ibe yisimo esiqinile ngesivinini esikhulu ngemisebe ye-UV enobude obuthile beza.Ukusabela kokwelapha isithombe empeleni kuyisithombe esiqalisiwe se-polymerization kanye nokusabela okuxhumanisayo.Izembatho ezelaphekayo ze-UV ziye zaqashelwa ngazwi linye yimboni yokumboza ngenxa yokwelapha kwazo okunezinga eliphezulu nezici ezivumelana nemvelo.
Kungakanani okwaziyo ngopende we-UV?Ngo-1968, i-Bayer yahola ekusebenziseni uhlelo lokwelapha lwe-UV lwe-resin engagcwele kanye ne-benzoic acid ukukhiqiza imikhiqizo yokuthengisa, futhi yathuthukisa isizukulwane sokuqala sezingubo zokupholisa ze-UV.Ekuqaleni kwawo-1970, i-Sun Chemical Company kanye nenkampani ye-immontconciso bakha uyinki oyelapheka we-UV ngokulandelana.
Ekuqaleni kwawo-1980, abakhiqizi be-flooring baseTaiwan baqala ukutshala imali futhi bakhe izimboni ezweni elikhulu, kanye nobuchwepheshe bokusebenzisa i-uvpaint kanye nokukhiqiza nabo kwethulwa.Ngaphambi maphakathi nawo-1990s, ama-uvcoatings ayesetshenziselwa ikakhulukazi uqalo nokucubungula phansi ngokhuni kanye nokupholisha ikhava yepulasitiki, futhi ayebonakala obala.
Eminyakeni yamuva, ngokucutshungulwa okukhulu kwefenisha yasekhaya, i-uvpaint iye yangena kancane kancane emkhakheni wokugqoka izinkuni, futhi izinzuzo zayo ziye zaqashelwa kabanzi.Njengamanje, i-uvpaint isetshenziswe kabanzi ephepheni, epulasitiki, ensimbi, engilazini, e-ceramics nakweminye imikhakha, futhi ithuthuka ngendlela yokusebenza.
Ithemba lemakethe lezingubo ze-UV
Upende we-UV, wazi kangakanani ngezingubo zendabuko ezisetshenziswa embonini yefenisha yasekhaya okwamanje kuseyiPu, PE kanye ne-NC.Ngokwakhiwa kokufafaza, ukusebenza kahle kuphansi, futhi kunzima ukuqasha abasebenzi futhi izindleko zabasebenzi ziphezulu.Kuphela ngokwenza ngcono izinga lokukhiqiza okuzenzakalelayo kwamabhizinisi akhiqiza ifenisha lapho bengakwazi khona ukwephula ibhodlela lentuthuko futhi bathuthukise ukusebenza kahle kwebhizinisi.Ngakolunye uhlangothi, i-VOC ekhishwa izimboni zefenisha zisebenzisa izimbotshana zendabuko isibe umthombo obalulekile wokungcoliswa kwemvelo.Njengamanje, umnotho wekhabhoni ephansi kanye nokusetshenziswa okuluhlaza kuyathandwa, okuzokwenza nakanjani kube nezindinganiso ezintsha zobuchwepheshe kanye nezithiyo zohwebo.Amazwe athuthukile njenge-Europe kanye ne-United States asungule futhi akhipha izinyathelo zokulawula eziningi ukuze kugqugquzelwe imboni yefenisha ukuthi ithuthuke ekuvikeleni uhlaza nemvelo.Abakhiqizi befenisha yasekhaya, ikakhulukazi amabhizinisi agxile ekuthekeliseni kwamanye amazwe, babhekene nezinselelo kuphela ngaphambilini.
Ngaphansi kwesizinda sokuthuthukiswa kwemboni, ama-uvcoatings ahambisana nokuthambekela kwezikhathi futhi abe umkhuba omusha ekuthuthukisweni kokugqoka ifenisha.Izinzuzo zayo njengokuvikela imvelo nokonga amandla kanye nokunciphisa ukungcola ziyavela kancane kancane, okuphinde kwadonsa ukunaka kweminyango kazwelonke efanele.UHlelo Lweminyaka Eyi-11 Lweminyaka Emihlanu lokuthuthukiswa kwemboni yokumboza kanye nohlelo lwesikhathi esimaphakathi neside lokuthuthukiswa kwesayensi nobuchwepheshe bemboni yokuhlanganisa ibeka ngokucacile isidingo sokuthuthukisa ngamandla ama-UV ahambisana nemvelo.Upende we-UV usuzosuka okokuqala embonini, futhi ithemba lemakethe alinakulinganiswa.
