Ubuchwepheshe bokuphulukisa i-UV ubuchwepheshe obusha obubhekene nekhulunyaka lama-21 obusebenza kahle kakhulu, ukuvikelwa kwemvelo, ukonga amandla kanye nekhwalithi ephezulu.Isetshenziswa kabanzi kuma-coatings, ama-adhesives, ama-inki, ama-optoelectronics neminye imikhakha.Kusukela ilungelo lobunikazi lokuqala le-UV lokuphulukisa eliyinki latholwa yinkampani yaseMelika yase-inmont ngo-1946 futhi isizukulwane sokuqala se-UV ephulukisa izinkuni ze-UV sathuthukiswa yinkampani yaseJalimane i-Bayer ngo-1968, ama-UV elaphayo athuthuke ngokushesha emhlabeni wonke.Emashumini eminyaka amuva nje, inani elikhulu lama-photoinitiators amasha nasebenza kahle, ama-resin, ama-monomers kanye nemithombo yokukhanya ye-UV ethuthukisiwe isetshenziswe ekwelapheni kwe-UV, okukhuthaze ukuthuthukiswa kwemboni ye-UV yokwelapha yokuhlanganisa.
Ubuchwepheshe bokwelapha ukukhanya bubhekisela kubuchwepheshe obuthatha ukukhanya njengamandla futhi bubolise ama-photoinitiators ngokukhanya ukuze kukhiqizwe izinhlobo ezisebenzayo ezifana nama-radicals mahhala noma ama-ion.Lezi zinhlobo ezisebenzayo ziqala i-monomer polymerization futhi ngokushesha ziyiguqule isuka oketshezini iye kwi-polymer eqinile.Ibizwa ngokuthi ubuchwepheshe obuluhlaza ngenxa yezinzuzo zayo zokusebenzisa amandla aphansi (1 / 5 kuya ku-1 / 10 ye-polymerization eshisayo), isivinini esisheshayo (ukugcwalisa inqubo ye-polymerization ngemizuzwana embalwa kuya emashumini amasekhondi), akukho ukungcola (akukho volatilization ye-solvent) , njll.
Njengamanje, i-China isibe yilinye lamazwe amakhulu kakhulu okusebenza kwezinto zokwakha i-photopolymerization, futhi ukuthuthukiswa kwayo kulo mkhakha kuye kwaheha ukunakwa kwamazwe ngamazwe.Ekungcolisweni kwemvelo okwandayo okwandayo kwanamuhla, kubaluleke kakhulu ukuthuthukisa ubuchwepheshe bokufothopolymerization obungangcolisi futhi obulungele imvelo.Ngokwezibalo, ukukhishwa kwaminyaka yonke kwama-hydrocarbons emkhathini emhlabeni wonke kungamathani ayizigidi ezingama-20, iningi lawo okungama-organic solvents kuma-coatings.I-solvent ye-organic ekhishelwa emkhathini ngesikhathi sokukhiqiza i-coating ingu-2% wokukhiqiza okunamathelayo, futhi i-solvent ephilayo eguquguqukayo ekusetshenzisweni kokumboza ingama-50% ~ 80% wokukhiqizwa kokumboza.Ukuze kuncishiswe ukukhishwa kokungcola, okokugcotshwa kwe-UV kancane kancane kungena esikhundleni sezinto ezivamile zokuphulukisa ukushisa kanye nama-solvent asekelwe.
Ngokuqhubeka okuqhubekayo kobuchwepheshe bokuphulukisa ukukhanya, inkambu yokusetshenziswa kwayo izonwetshwa kancane kancane.Ubuchwepheshe bokuqala bokuphulukisa ukukhanya kwakungokwezimbozo, ngoba ukungena nokumuncwa kokukhanya ezinhlelweni ezinemibala kwakungeke kuxazululwe ngaleso sikhathi.Kodwa-ke, ngokuthuthukiswa kwama-photoinitiators kanye nokuthuthukiswa kwamandla omthombo wokukhanya, ubuchwepheshe bokuphulukisa ukukhanya bungahlangabezana kancane kancane nezidingo zezinhlelo ze-inki ezahlukene, futhi uyinki wokwelapha ukukhanya uthuthuke ngokushesha.Eminyakeni yamuva nje, ngokuqhubeka okuqhubekayo kobuchwepheshe bokuphulukisa ukukhanya, bungangena kweminye imikhakha.Ngenxa yenqubekelaphambili yocwaningo oluyisisekelo, ukuqonda indlela eyisisekelo yokwelapha ukukhanya kujule kakhulu, futhi izinguquko zendawo yenhlalo zizophinde zibeke phambili izidingo ezintsha zobuchwepheshe bokuphulukisa ukukhanya, okungasungulwa futhi kuthuthukiswe.
Imikhiqizo ye-UV yokwelapha ihlanganisa:
Uqalo olulaphekayo lwe-UV kanye nezingubo zokhuni: njengomkhiqizo oyisici e-China, izimbotshana ezelaphekayo ze-UV zisetshenziswa kakhulu ukwenza ifenisha yoqalo kanye ne-bamboo flooring.Ingxenye ye-UV enamathela ezitezi ezihlukahlukene e-China iphezulu kakhulu, okungenye yezindlela ezibalulekile zokusetshenziswa kwe-UV.
Ukufakwa kwephepha elelaphekayo kwe-UV: njengenye yezinhlobo zokuqala zokumboza ze-UV, i-UV yokupholisha iphepha isetshenziswa ezintweni ezihlukahlukene eziphrintiwe, ikakhulukazi esembozweni sezikhangiso nezincwadi.Njengamanje, kuseyinhlobonhlobo enkulu ye-UV enamathelayo.
Izingubo zepulasitiki ezilaphekayo ze-UV: imikhiqizo yepulasitiki idinga ukumbozwa ukuze ihlangabezane nezidingo zobuhle nokuqina.Kunezinhlobo eziningi zezingubo zepulasitiki ze-UV ezinomehluko omkhulu ezidingweni, kodwa eziningi zazo zihlobisa.Izembatho zepulasitiki ze-UV ezivame kakhulu amagobolondo ezinto ezihlukahlukene zasendlini kanye nomakhalekhukhwini.
I-vacuum coating elula yokwelapha: ukuze kwandiswe ukuthungwa kokupakisha, indlela evame kakhulu ukuhlanganisa amapulasitiki nge-vacuum evaporation.I-UV primer, ijazi lokuqeda kanye neminye imikhiqizo iyadingeka kule nqubo, esetshenziselwa ikakhulukazi ukupakishwa kwezimonyo.
Izingubo zensimbi ezelaphekayo ze-UV: Izembatho zensimbi ezelaphekayo ze-UV zihlanganisa i-UV antirust primer, i-UV yensimbi eyelaphekayo evikelayo yesikhashana, i-metal UV yokuhlobisa i-UV, i-metal UV yokuvikela indawo yokuvikela, njll.
I-UV yokuphulukisa i-fiber optical coating: ukukhiqizwa kwe-fiber optical kudinga ukumbozwa izikhathi ezingu-4-5 ukusuka phansi kuya phezulu.Njengamanje, cishe zonke ziqedwa ngokwelashwa kwe-UV.Ukufakwa kwe-UV optical fiber nakho kuyisibonelo esiphumelele kakhulu sohlelo lokusebenza lokuphulukisa i-UV, futhi ijubane layo lokuphulukisa le-UV lingafinyelela ku-3000 m / min.
I-conformal coating yokwelapha ukukhanya: emikhiqizweni yangaphandle, ikakhulukazi imikhiqizo ye-elekthronikhi, idinga ukumelana nokuhlolwa kwezinguquko zemvelo ezifana nomoya nemvula.Ukuze kuqinisekiswe ukusetshenziswa okuvamile kwesikhathi eside kwemikhiqizo, izinto zikagesi zidinga ukuvikelwa.I-UV conformal coating yenzelwe lolu hlelo lokusebenza, okuhloswe ngayo ukwandisa impilo yesevisi kanye nokuzinza kwezinto zikagesi.
Ukugqoka ingilazi yokwelapha ukukhanya: umhlobiso wengilazi ngokwawo umpofu kakhulu.Uma ingilazi idinga ukukhiqiza umphumela wombala, idinga ukumbozwa.Kwavela ukumbozwa kwengilazi ye-UV.Lolu hlobo lomkhiqizo lunezidingo eziphezulu zokumelana nokuguga, ukumelana ne-asidi kanye ne-alkali.Kungumkhiqizo we-UV osezingeni eliphezulu.
Izembatho ze-ceramic ezilaphekayo ze-UV: ukuze kwandiswe ubuhle be-ceramics, ukugqoka okuphezulu kuyadingeka.Njengamanje, izembatho ze-UV ezisetshenziswa kuma-ceramics ikakhulukazi zifaka i-ceramic inkjet coatings, i-ceramic flower paper coatings, njll.
Ukugqoka amatshe okuphulukisa ukukhanya: itshe lemvelo lizoba namaphutha ahlukahlukene.Ukuze kuthuthukiswe ubuhle balo, itshe lidinga ukuguqulwa.Inhloso eyinhloko yokugqoka amatshe okuphulukisa ukukhanya ukulungisa iziphambeko zamatshe emvelo, ngezidingo eziphakeme zamandla, umbala, ukumelana nokugqoka kanye nokumelana nokuguga.
I-UV yokwelapha isikhumba: I-UV lesikhumba enamathela inezigaba ezimbili.Enye i-UV yesikhumba yokukhishwa kwesikhumba, esetshenziselwa ukulungiswa kwephepha lephethini lesikhumba sokwenziwa, futhi umthamo walo mkhulu kakhulu;Okunye ukuhlobisa kwesikhumba, okushintsha ukubukeka kwesikhumba semvelo noma sokwenziwa futhi sithuthukise umhlobiso wayo.
Izingubo zezimoto zokuphulukisa ukukhanya: ubuchwepheshe bokuphulukisa ukukhanya buzosetshenziselwa izibani kusuka ngaphakathi kuya ngaphandle.Izitsha zamalambu namaLampshades adinga ukugcotshwa ngobuchwepheshe bokuphulukisa ukukhanya;Ubuchwepheshe bokuphulukisa ukukhanya busetshenziswa enanini elikhulu lezingxenye ngaphakathi nangaphandle komhlobiso wemoto, njengephaneli yezinsimbi, isibuko esibuka ngemuva, isiteringi, isibambo segiya, ihabhu lamasondo, umugqa wokunquma wangaphakathi, njll;I-bumper yemoto ilungiswa ngobuchwepheshe bokuphulukisa ukukhanya, futhi ukumboza okungaphezulu kubuye kugcwaliswe nge-polymerization ekhanyayo;Izinto zokwelapha ukukhanya nazo ziyadingeka ukuze kulungiswe inani elikhulu lezingxenye ze-elekthronikhi zezimoto, njengokuboniswa ebhodini, ibhodi lokulawula eliphakathi nokunye;I-anti-aging coating ebusweni bezingubo zemoto ezithandwayo nayo igcwaliswa ngobuchwepheshe bokuphulukisa ukukhanya;I-coat body coating izuze ukuphulukiswa okukhanyayo;Ubuchwepheshe bokuphulukisa ukukhanya buzophinde busetshenziswe ekulungiseni ifilimu kapende wemoto nokulungisa umonakalo wezingilazi.
