Izinto zokupakisha zezimonyo ziyipulasitiki ikakhulukazi, ingilazi nephepha. Ngesikhathi sokusebenzisa, ukucubungula kanye nokugcinwa kwamapulasitiki, ngenxa yezici ezahlukahlukene zangaphandle ezinjengokukhanya, umoya-mpilo, ukushisa, iphunga, imvula, isikhunta, isakhiwo samakhemikhali samapulasitiki abhujisiwe, okuholela ekulahlekelweni kwabo izakhiwo ezinhle kakhulu. Le nto ivame ukubizwa ngokuthi ukuguga. Ukubonakaliswa okuyinhloko kokuguga kwepulasitiki kukhona i-dillowration, izinguquko ezeza ngezakhiwo ezibonakalayo, izinguquko ezeza ngezakhiwo zemishini kanye nezinguquko ezizakhiweni zikagesi.
1. Isizinda sokuguga kwepulasitiki
Ezimpilweni zethu, eminye imikhiqizo ivezwa ngokungafanele ekukhanyeni, futhi ukukhanya kwe-ultraviolet elangeni, kuhambisana nokushisa okuphezulu, imvula namazolo, kuzodala ukuthi umkhiqizo ulahlekelwe yimicimbi yokuguga njengokulahleka kwamandla, ukuqhekeka, ukuncipha kanye powling. Ukukhanya kwelanga nomswakama yizici eziyinhloko ezibangela ukuguga kwezinto ezibonakalayo. Ilanga lingadala ukuthi izinto eziningi zidangele, ezihlobene nokuzwela kanye nokubukeka kwezinto zokwakha. Indwangu ngayinye iphendula ngendlela ehlukile ku-spectrum.
Izici ezijwayelekile ezigugile kakhulu zamapulasitiki endaweni yemvelo zingukushisa nokukhanya kwe-ultraviolet, ngoba imvelo amapulasitiki avezwa kakhulu ukushisa nokukhanya kwelanga (ukukhanya kwe-ultraviolet). Ukutadisha ukuguga kwamapulasitiki okubangelwa yilezi zinhlobo ezimbili zezindawo kubaluleke kakhulu kwimvelo yangempela yokusebenzisa. Ukuhlolwa kwayo kokuguga kungahlukaniswa ngezigaba ezimbili: Ukuvezwa kwangaphandle kanye nokuhlolwa kokuguga kwelebhu okusheshayo.
Ngaphambi kokuthi umkhiqizo usetshenziswe ekusetshenzisweni okukhulu, ukuhlolwa kokuguga okukhanyayo kufanele kwenziwe ukuze kuhlolwe ukumelana kwayo ukuguga. Kodwa-ke, ukuguga kwemvelo kungathatha iminyaka eminingana noma isikhathi eside ukubona imiphumela, ngokusobala okungahambelani nokukhiqizwa kwangempela. Ngaphezu kwalokho, izimo zezulu ezikhathini ezahlukahlukene zihlukile. Izinto ezifanayo zokuhlola zidinga ukuhlolwa ezindaweni ezahlukahlukene, ezandisa kakhulu izindleko zokuhlola.
2. Ukuhlolwa okuvezwa kwangaphandle
Ukuchazwa okuqondile kwangaphandle kubhekisele ukuvezwa ukukhanya kwelanga nezinye izimo zezulu. Kuyindlela eqondile eqondile yokuhlola ukumelana kwesimo sezulu kwezinto zepulasitiki.
Izinzuzo:
Izindleko eziphansi ngokuphelele
Ukuvumelana okuhle
Elula futhi kulula ukusebenza
Okubi:
Imvamisa umjikelezo omude kakhulu
Ukuhlukahluka kwesimo sezulu emhlabeni jikelele
Amasampula ahlukene anokuzwela okuhlukile ezimweni ezihlukile
I-3. Indlela yokuhlola ukushesha kwelebhu
Ukuhlolwa kokuguga kweLabhorato ngeLaboratory akwazi nje ukunciphisa umjikelezo, kepha futhi kubuye kube nokuphindaphindeka okuhle kanye nobubanzi besicelo esibanzi. Kuqediwe elabhorethri kuyo yonke inqubo, ngaphandle kokubheka imikhawulo yendawo, futhi kulula ukusebenza futhi nokulawulwa okuqinile. Ukulingisa indawo yokukhanyisa yangempela nokusebenzisa izindlela zokuguga ezisheshayo ezisheshayo zingafinyelela inhloso yokuhlola ngokushesha ukusebenza kwezinto ezibonakalayo ngokushesha. Izindlela eziphambili ezisetshenzisiwe zingukuhlolwa kokuguga okukhanyayo kwe-ultraviolet, ukuhlolwa kwesibani se-XENONOLET kanye nokuguga okukhanyayo kwekhabhoni.
1. Indlela yokuhlola ukulimala kwe-xenon ukukhanya
Ukuhlolwa kwesibani se-Xenon Lamp kungukuhlola okulingisa i-Sunlight Spectrum ephelele. Ukuhlolwa kwesibani se-XENONAL kungalingisa isimo sezulu semvelo sokufakelwa ngesikhathi esifushane. Kuyindlela ebalulekile yokuhlola amafomula futhi uthuthukise ukwakheka komkhiqizo kwinqubo yocwaningo lwesayensi nokukhiqizwa, futhi kuyingxenye ebalulekile yokuhlolwa kwekhwalithi yomkhiqizo.
Imininingwane yokuhlola isibani se-XENONOn ingasiza ekukhetheni izinto ezintsha, iguqule izinto ezikhona, futhi ihlole ukuthi izinguquko kumafomula zithinta kanjani ukuqina kwemikhiqizo
Isimiso Esiyisisekelo: ICennon Lamp Test Chamber isebenzisa izibani zeXenon ukulingisa imiphumela yokukhanya kwelanga, futhi isebenzise umswakama onqunyelwe ukulingisa imvula namazolo. Izinto ezihlolwe zibekwe emjikelezweni wokushintshana ngokukhanya kanye nomswakama endaweni yokushisa ethile yokuhlola, futhi kungaveza kabusha izingozi ezenzeka ngaphandle kwezinyanga noma amasonto ambalwa.
Isicelo sokuhlola:
Inganikeza ukuzunguzela okuhambisanayo kwemvelo nokuhlolwa okusheshisiwe kocwaningo lwesayensi, ukuthuthukiswa komkhiqizo kanye nokulawulwa kwekhwalithi.
Ingasetshenziselwa ukukhethwa kwezinto ezintsha, ukuthuthukiswa kwezinto ezikhona noma ukuhlolwa kokuqina ngemuva kwezinguquko ekubukeni okubonakalayo.
Kungalingisa kahle izinguquko ezibangelwa izinto ezivezwa ukukhanya kwelanga ngaphansi kwezimo ezahlukahlukene zezemvelo.
2. Indlela yokuhlola yokuhlola ukukhanya kwe-UV
Ukuhlolwa kwe-UV auring ikakhulukazi kulingisa umphumela wokucekelwa phansi wokukhanya kwe-UV ngokukhanya kwelanga ngomkhiqizo. Ngasikhathi sinye, kungabuye kuphinde kwaphinde kudalwe umonakalo odalwe yimvula namazolo. Ukuhlolwa kwenziwa ngokudalula okuqukethwe ukuze kuhlolwe kumjikelezo olawulayo olawulayo wokukhanya kwelanga kanye nomswakama ngenkathi ukhulisa izinga lokushisa. Amalambu we-weltraviolet we-fluorescent asetshenziselwa ukulingisa ukukhanya kwelanga, futhi ithonya lomswakama lingalinganiswa futhi ngokuvuselelwa noma ukufafaza.
I-Fluorescent UV Lamp iyi-Talleng-Pressure ye-Mercury I-Wavelength ye-254NM. Ngenxa yokwengezwa kwe-phosphorus coexistence ukuyiguqula ibe yi-wavelthth ende, ukusatshalaliswa kwamandla kwesibani se-fluorescent UV kuncike kwi-Emission Spectrum ekhiqizwe yi-phosphorus couxiste ekhiqizwa yi-phosphorus couexiste ekhiqizwe yi-phosphorus couexiste ekhiqizwe yi-phosphorus couexiste ekhiqizwa yi-phosphorus couexiste ekhiqizwa yi-tube yengilazi. Izibani ze-Fluorescent zivame ukuhlukaniswa nge-UVA ne-UVB. Uhlelo lokusebenza lokuvezwa kwezinto ezibonakalayo lunquma ukuthi yiluphi uhlobo lwesibani se-UV okufanele lusetshenziswe.
I-3. I-Carbon Arc Lamp I-Age Egung Test Test
Isibani se-Carbon Arc ubuchwepheshe obudala. Ithuluzi le-arc le-carbon ekuqaleni lalisetshenziswa ngamakhemikhali odayi wokwenza okwenziwe ngamaJalimane ukuhlola ukushesha okukhanyayo kwezindwangu ezidwetshiwe. Izibani ze-Carbon Arc zihlukaniswe izibani ezivaliwe nezivulekile ze-carbon arc. Kungakhathalekile ukuthi uhlobo lwekhangu lwe-carbon arc, i-spectrum yalo ihluke kakhulu kusuka kwisibuko selanga. Ngenxa yomlando omude walobu buchwepheshe bephrojekthi, ubuchwepheshe bokuqala bokufanisa bokufanisa ukusukuma sekulingisa esebenzisa le mishini, ngakho-ke le ndlela isengabonakala ezindinganisweni zangaphambilini, ikakhulukazi ezindinganisweni zokuqala zaseJapan, lapho ubuchwepheshe be-Carbon Arc Arc belusetshenziswa njengokukhanya kokufakelwa Indlela yokuhlola yokuguga.
