Yiziphi izinzuzo zekhebula elimelana nomlilo?

Izintambo ezingashisi ngokuvamile isebenzisa isakhiwo esinezingqimba ezimbili noma ezinezingqimba eziningi, ngezinto ezikhethekile ezifana namateyipu e-mica angashisi ngaphakathi. Lapho umlilo uqhuma, iteyipu ye-mica ingakha ifilimu eqinile yokuvikela emazingeni okushisa aphezulu, ihlukanise ilangabi nokushisa, futhi ivikele abaqhubi bangaphakathi kanye nezingqimba zokuvikela ekulimaleni, ngaleyo ndlela igcine ukusebenza okuvamile kwesekethe. Izintambo ezivamile azinaso isakhiwo esinjalo esimelana nomlilo futhi zishiswa kalula emlilweni, okuholela ekuphazamisekeni kwesekethe.

Abaqhubi be- izintambo ezingashisi ngokuvamile zisebenzisa i-alloy zethusi noma zethusi enezinga eliphezulu lokuncibilika, kanti izinto zokuvikela kanye ne-sheath nazo zinokumelana nomlilo okuphezulu, ezikwazi ukumelana namazinga okushisa aphezulu. Isibonelo, izinto zokuvikela zezinye izintambo ezingamelani nomlilo zingahlala zizinzile ekushiseni okuphezulu okungu-950 - 1000°C, okuqinisekisa ukuthi izintambo zisasebenza ngokujwayelekile isikhathi esithile endaweni yomlilo. Ngokuphambene nalokho, izinto zezintambo ezivamile zizoncibilika noma zonakale ngokushesha emazingeni okushisa aphezulu kangaka.

Izinto zokuvikela ezisetshenziswa ku-insulation izintambo ezingashisi Akukhona nje kuphela ukuthi zimelana nomlilo kodwa futhi zisebenza kahle kakhulu ekushiseni. Lezi zinto zimelana nokushisa okuphezulu kanye namandla e-dielectric, okungavimbela kangcono ukuvuza kwamanje kanye nezimo ze-short-circuit. Izinto zokushisa zezintambo ezivamile zingase zibhekane nokwehla kokusebenza kokushisa ngesikhathi sokusetshenziswa isikhathi eside noma endaweni eshisa kakhulu, futhi zithambekele ezingozini zokuphepha njengokuvuza kukagesi.

Ingqimba yokushisa izintambo ezingashisi ngokuvamile inokusebenza okuhle okumelana nomswakama, okungavimbela ngempumelelo umswakama ukuthi ungene ngaphakathi kwezintambo futhi kugweme ukwehla kokusebenza kokuvikela ngenxa yomswakama. Uma izintambo ezivamile zisetshenziswa endaweni enomswakama, ukusebenza kwazo kokuvikela kungathinteka kakhulu, futhi kungase kube nokungasebenzi kahle.

Ukuze kugcinwe ukusebenza okuzinzile ezindaweni ezinzima njengemililo, izintambo ezingashisi ngokuvamile zinesakhiwo sokuvikela esiqinile, njengokwengeza isivikelo se-steel tape noma isivikelo se-steel wire, njll. Lezi zendlalelo zesivikelo zingathuthukisa ukumelana nokucindezela, ukuthambekela, kanye nokushayisana kwezintambo, okwenza zingabi sengozini yokulimala uma zibhekene namandla angaphandle. Izintambo ezivamile ngokuvamile azinaso isakhiwo esiqiniswe kanjalo, futhi amandla azo okusebenza aphansi kakhulu.

Ngenkathi kuqinisekiswa amandla omshini, izintambo ezingashisi futhi zinokuguquguquka okungcono, okulula ukubekelwa nokufakwa. Ngisho nasezindaweni eziyinkimbinkimbi zokuxhuma izintambo, zingagotshwa futhi zibekwe kalula ngaphandle kokulimaza isakhiwo sangaphakathi sezintambo ngenxa yokugoba ngokweqile. Izintambo ezivamile zingase zibe nokuguquguquka okuncane, ikakhulukazi kwezinye izintambo ezinkulu, futhi kungase kuhlangatshezwane nobunzima obuningi ngesikhathi sokubekelwa.

Ngenxa yokusetshenziswa kwezinto ezisebenza kahle kakhulu kanye nezinqubo zokukhiqiza ezithuthukisiwe, izintambo ezingashisi zisebenza kangcono ekumelaneni nokuguga kunezintambo ezivamile. Ngesikhathi zisetshenziswa isikhathi eside, zingamelana kangcono nomthelela wezinto zemvelo (njengemisebe ye-ultraviolet, i-oxidation, izinguquko zokushisa, njll.), zehlise ijubane lokuguga kwezinto, ngaleyo ndlela zandise impilo yezintambo. Lapho izintambo ezivamile zivezwa ezindaweni ezinzima isikhathi eside, izinkinga ezifana nokuguga kokushisa kanye nokuqhekeka kwe-sheath cishe zizovela, okuthinta ukusetshenziswa kwazo okuvamile.

Izintambo ezingashisi zingamelana namazinga okushisa aphezulu, futhi ukusebenza kwazo kushintsha kancane ngaphansi kwamazinga okushisa ajwayelekile okusebenza kanye namazinga okushisa agcwele ngokweqile esikhathi esifushane. Lokhu kwenza zikwazi ukusetshenziswa kwezinye izindawo ezinokushisa okuphezulu ngaphandle kokunciphisa isikhathi sazo sokusebenza ngenxa yamazinga okushisa aphezulu kakhulu. Endaweni enokushisa okuphezulu, ukusebenza kwezinto zezintambo ezivamile kuzowohloka ngokushesha, okuholela ekufinyezweni okukhulu kwesikhathi sokusebenza kwezintambo.
