Igumbi lokuhlola ukuguga kwesimo sezulu se-UV lingenye indlela yokuhlola i-photoaging elingisa ukukhanya elangeni. Lingaphinda likhiqize umonakalo odalwe yimvula namazolo. Imishini ihlolwa ngokudalula izinto ezizohlolwa emjikelezweni olawulwayo wokukhanya kwelanga nomswakama kanye nokukhulisa izinga lokushisa. Imishini isebenzisa izibani ze-ultraviolet fluorescent ukulingisa ilanga, futhi ingalingisa nomphumela womswakama ngokufiphaza noma ngokufutha.
Kuthatha izinsuku noma amasonto ambalwa kuphela ukuthi idivayisi ikhiqize kabusha umonakalo othatha izinyanga noma iminyaka ukuba ngaphandle. Umonakalo uhlanganisa ikakhulukazi ukushintsha kombala, ukushintsha kombala, ukwehla kokukhanya, ukuqhekeka, ukufiphala, ukuqhekeka, ukuncipha kwamandla, kanye nokubola. Idatha yokuhlola enikezwa yimishini ingaba usizo ekukhetheni izinto ezintsha, ekuthuthukiseni izinto ezikhona, noma ekuhlolweni kwezinguquko zokwakheka ezithinta ukuqina kwemikhiqizo. Imishini ingabikezela izinguquko umkhiqizo ozohlangabezana nazo ngaphandle.
Nakuba i-UV ikhiqiza u-5% kuphela wokukhanya kwelanga, iyisici esiyinhloko esibangela ukuqina kwemikhiqizo yangaphandle ukuthi yehle. Lokhu kungenxa yokuthi ukusabela kwe-photochemical kokukhanya kwelanga kuyanda ngokuncipha kobude be-wavelength. Ngakho-ke, lapho ulingisa umonakalo wokukhanya kwelanga ezimpahleni ezibonakalayo zezinto, akudingekile ukukhiqiza kabusha lonke ububanzi bokukhanya kwelanga. Ezimweni eziningi, udinga kuphela ukulingisa ukukhanya kwe-UV kwegagasi elifushane. Isizathu sokuthi isibani se-UV sisetshenziswe ku-UV accelerated weather tester ukuthi zizinzile kakhulu kunezinye izitsha futhi zingakhiqiza imiphumela yokuhlola kangcono. Kuyindlela engcono kakhulu yokulingisa umphumela wokukhanya kwelanga ezimpahleni ezibonakalayo ngokusebenzisa izibani ze-UV ezikhanyayo, njengokwehla kokukhanya, ukuqhekeka, ukuqhekeka, njalo njalo. Kunezibani eziningana ezahlukene ze-UV ezitholakalayo. Iningi lalezi zibani ze-UV likhiqiza ukukhanya kwe-ultraviolet, okungabonakali kanye nokukhanya kwe-infrared. Umehluko omkhulu wezibani ubonakala emehluko wamandla e-UV aphelele akhiqizwa ebangeni lawo lobude be-wavelength. Izibani ezahlukene zizokhiqiza imiphumela yokuhlola ehlukene. Indawo yokusetshenziswa kokuvezwa kwangempela ingasho ukuthi yiluphi uhlobo lwesibani se-UV okufanele sikhethwe.
I-UVA-340, ukukhetha okungcono kakhulu kokulingisa imisebe ye-ultraviolet yelanga
I-UVA-340 ingalingisa i-solar spectrum ku-critical short wavelength range, okungukuthi, i-spectrum enobubanzi be-wavelength obungu-295-360nm. I-UVA-340 ingakhiqiza kuphela i-spectrum ye-UV wavelength engatholakala ekukhanyeni kwelanga.
I-UVB-313 yokuhlolwa kokusheshisa okuphezulu
I-UVB-313 inganikeza imiphumela yokuhlolwa ngokushesha. Basebenzisa ama-UV amafushane ane-wavelength anamandla kunalawo atholakala emhlabeni namuhla. Nakuba lezi zibani ze-UV ezinde kakhulu kunamagagasi emvelo zingasheshisa ukuhlolwa ngezinga elikhulu kakhulu, zizophinde zibangele umonakalo ongaguquki nowangempela kwezinye izinto.
Indinganiso ichaza isibani se-ultraviolet esikhanyayo esikhipha ngaphansi kuka-300nm ngaphansi kuka-2% wamandla okukhanya aphelele, ngokuvamile abizwa ngokuthi isibani se-UV-A; isibani se-ultraviolet esikhanyayo esinamandla okukhipha ngaphansi kuka-300nm sikhulu kune-10% wamandla okukhanya aphelele, ngokuvamile abizwa ngokuthi isibani se-UV-B;
Ububanzi bobude be-UV-A bungu-315-400nm, kanti i-UV-B ingu-280-315nm;
Isikhathi sezinto ezivezwe emswakama ngaphandle singafinyelela emahoreni ayi-12 ngosuku. Imiphumela ikhombisa ukuthi isizathu esiyinhloko salobu mswakama bangaphandle amazolo, hhayi imvula. Umhloli wokumelana nesimo sezulu osheshayo we-UV ulingisa umphumela womswakama ngaphandle ngochungechunge lwezimiso ezihlukile zokuvunda. Emjikelezweni wokuvunda kwemishini, kunethangi lokugcina amanzi phansi kwebhokisi futhi elifudunyezwayo ukuze kukhiqizwe umhwamuko wamanzi. Umhwamuko oshisayo ugcina umswakama ohlobene ekamelweni lokuhlola ngamaphesenti ayi-100 futhi ugcina izinga lokushisa eliphakeme kakhulu. Umkhiqizo wenzelwe ukuqinisekisa ukuthi isampula yokuhlola empeleni yakha udonga oluseceleni lwegumbi lokuhlola ukuze ingemuva lengxenye yokuhlola ivezwe emoyeni ozungezile wangaphakathi. Umphumela wokupholisa womoya wangaphakathi ubangela ukuthi izinga lokushisa lobuso lengxenye yokuhlola lehle liye ezingeni lamadigri amaningana aphansi kunezinga lokushisa lomhwamuko. Ukubonakala kwalokhu mehluko wokushisa kuholela emanzini acwengekile akhiqizwa ukuvunda ebusweni besampula ngesikhathi somjikelezo wonke wokuvunda. Lokhu kuvunda kungamanzi acwengekile azinzile kakhulu. Amanzi ahlanzekile athuthukisa ukuphindaphindeka kokuhlolwa futhi agwema inkinga yamabala amanzi.
Ngenxa yokuthi isikhathi sokuchayeka ngaphandle komswakama singafika emahoreni ayi-12 ngosuku, umjikelezo womswakama womhloli wokumelana nesimo sezulu osheshayo we-UV ngokuvamile uhlala amahora amaningana. Sincoma ukuthi umjikelezo ngamunye wokuchayeka uthathe okungenani amahora ama-4. Qaphela ukuthi ukuchayeka kwe-UV kanye nokuchayeka emishinini kwenziwa ngokwahlukana futhi kuhambisana nezimo zezulu zangempela.
Kwezinye izinhlelo zokusebenza, i-water spray ingalingisa kangcono ukusetshenziswa kokugcina kwezimo zemvelo. I-water spray iwusizo kakhulu
