Kuzicishamlilo nabasebenzi bezimboni abangena ezindaweni eziyingozi, i-Self-Contained Breathing Apparatus (SCBA) isebenza njengendlela yokuphila. Lawa majosaka ahlinzeka ngendawo yokuhlinzeka komoya ehlanzekile, evikela abasebenzisi entubeni enobuthi, intuthu, nokunye ukungcola. Ngokwesiko, amasilinda e-SCBA akhiwa ngensimbi, enikeza isivikelo esiqinile. Kodwa-ke, ukuthuthuka kwesayensi yezinto ezibonakalayo kuye kwaholela ekwandeni kwei-carbon fibre cylinders, ukuletha izinzuzo ezibalulekile ngenkathi yethula ukucatshangelwa okusha kokuphepha.
Ukuheha kweCarbon Fiber
Inzuzo eyinhloko ye-carbon fiber isesisindo sayo. Uma kuqhathaniswa nozakwabo bensimbi,i-carbon fibre cylinders ingaba lula ngo-70%. Lokhu kwehliswa kwesisindo kuhumushela ekwenyukeni kokunyakaza kanye nokuncipha kokukhathala kogqokile, okubaluleke kakhulu phakathi nokuthunyelwa okunwetshiwe noma ezindaweni ezivalekile.Isilinda esilulas iphinde ithuthukise ibhalansi yokugqoka kanye nokubamba, kubalulekile ekuzuleni ezindaweni ezinobuqili.
Ngaphandle kokonga isisindo, i-carbon fiber ikwazi ukumelana nokugqwala okuphakeme. Le ndawo ibaluleke kakhulu ezimeni zezimboni lapho ukuchayeka kumakhemikhali anonya kuwusongo oluqhubekayo. Amasilinda ensimbi, nakuba eqinile, asengozini yokugqwala nokonakala ngokuhamba kwesikhathi, okungase kubeke engcupheni ubuqotho bawo.
Ukuphepha Kuqala: Ukucatshangelwa Okubalulekile
Nakuba i-carbon fiber inikeza izinzuzo ezingenakuphikwa, ukuqinisekisa ukuphepha kwala masilinda kudinga indlela ehlukile uma kuqhathaniswa nensimbi yendabuko. Nakhu okucatshangelwayo okubalulekile kokuphepha ukuze kusetshenziswe ngendlela efanele:
-Ukuhlola Nokunakekela:Ngokungafani namasilinda ensimbi, ngokuvamile angabonisa izimpawu zomonakalo obonakalayo, umonakalo we-carbon fiber ungase ubonakale kancane. Ukuhlola okuvamile kubalulekile ukuze kutholakale izinkinga ezingase zibe khona ngaphambi kokuba kuvele isimo esibucayi. Lokhu kuhlola kufanele kwenziwe ngabasebenzi abaqeqeshiwe belandela imihlahlandlela yomkhiqizi.
-Ukuhlolwa kwe-Hydrostatic:Ukuhlolwa kwe-Hydrostatic, noma “i-hydrotesting,” kuyindlela engonakali yokuhlola ubuqotho besakhiwo somkhumbi wengcindezi. Amasilinda angaphansi kwengcindezi edlula ingcindezi yokusebenza ukuze abone noma yibuphi ubuthakathaka. Kumasilinda e-SCBA, lokhu kuhlola kugunyazwa yimithetho futhi ngokuvamile kwenziwa njalo ngemva kweminyaka emihlanu. Nokho, abanye abakhiqizi bangase batuse ukuhlolwa okuvamile kwamasilinda e-carbon fibre ngenxa yezakhiwo zawo ezihlukile.
-Umthelela kanye nezinga lokushisa:I-carbon fiber, nakuba inamandla, ayinakunqotshwa. Ukwehlisa isilinda, ngisho nasendaweni ephansi, kungabangela umonakalo wangaphakathi ongase ungabonakali kalula. Ukuhlola amasilinda ukuqhekeka, i-delamination (分離 fēn lí), noma ezinye izimpawu zokulimala komthelela kubalulekile ngaphambi kokusetshenziswa ngakunye. Ngokufanayo, amazinga okushisa aphakeme kakhulu, kokubili ashisayo nabandayo, angenza buthaka isakhiwo esiyinhlanganisela se-carbon fiber. Abasebenzisi kufanele bagweme ukubeka amasilinda ekushiseni okudlulele noma kubanda, futhi bahambisane nezincomo zomkhiqizi zokugcinwa kanye namazinga okushisa okusetshenziswa.
-Ukuqeqeshwa nokuqwashisa:Ngenxa yamandla okulimala okufihliwe, ukuqeqeshwa okufanele kwabacimi bomlilo kanye nabasebenzi bezimboni abasebenzisacarbon fibre SCBA isilindas ibalulekile. Lokhu kuqeqeshwa kufanele kugcizelele ukubaluleka kokuhlolwa okuvamile, izingozi zomthelela nokweqisa kwezinga lokushisa, kanye nezinqubo ezifanele zokuphatha ukuze kuncishiswe lezi zingozi.
Okunye Okucatshangwayo: Umjikelezo Wokuphila Nokulungisa
Impilo yesevisi kacarbon fibre SCBA isilindangokuvamile isukela eminyakeni eyi-10 kuye kweyi-15, kuye ngomkhiqizi nezimo zokusebenzisa. Ngokungafani namasilinda ensimbi, angavame ukulungiswa ngemva kokuhluleka kwe-hydrotest, ukulungiswa kuvuliwei-carbon fibre cylinderngokuvamile awanconywa ngenxa yobunzima bokuqinisekisa ubuqotho besakhiwo ngemva kokwephulwa komthetho. Ngakho-ke, ukunakekelwa okufanele nokubamba kubaluleke kakhulu ukuze kwandiswe isikhathi sokuphila kwala masilinda.

Isiphetho: I-Symbiosis of Safety and Performance
I-Carbon fibre SCBA cylinderzimelela intuthuko enkulu kubuchwepheshe bokuvikela ukuphefumula. Isisindo sabo esilula kanye nokumelana nokugqwala okuphezulu kunikeza izinzuzo ezingenakuphikwa kubacishi bomlilo nabasebenzi bezimboni. Kodwa-ke, ukuqinisekisa ukuphepha okuqhubekayo kwalawa masilinda kudinga ukuzibophezela ekuhlolweni okuvamile, ukuqeqeshwa kwabasebenzisi, kanye nokuhambisana nezinqubo zokuphatha eziphephile. Ngokubeka phambili ukuphepha kanye nokusebenza, ubuchwepheshe be-carbon fibre SCBA bungaqhubeka buyithuluzi elisindisa ukuphila ezindaweni eziyingozi.
