Ukushisa okuphezulu kwengilazi yesakhiwo esishisayo kufakwe ingilazi epholile
Ukuhlolwa kwe-Heat soak (HST)
Ukuziqhumisa kwengilazi epholile
Ingilazi epholileinesici esingokwemvelo "sokuziqhumisa" - ingilazi epholile lapho kungekho senzo sangaphandle esiqondile kanye nesenzakalo esiphuka ngokuzenzakalelayo. Enkambisweni yokushisa ukucubungula, ukugcinwa, ukuthuthwa, ukufakwa, ukusetshenziswa, njll., ingilazi yokushisa i-self-explosion ingenzeka. Okwesimanjeingilazi entantayoamasu okukhiqiza awakwazi ukuqeda ngokuphelele ubukhona bokungcola kwe-nickel sulfide (NiS), ngakho-ke ukuziqhumisa okushisayo akunakugwenywa, okuyisici esingokwemvelo sengilazi epholile. Njengamanje, alikho izinga lanoma yiliphi izwe emhlabeni elikhawulela ukuziqhumisa kwengilazi eqinile. Ngokusho kokuhlangenwe nakho kwemboni yengilazi yaseChina, izinga lokuziqhumisa lengilazi evamile eqinile licishe libe ngu-3 ~ 5 ‰. Ukuze ugweme ukwenzeka kokuziqhumisa kwengilazi eqinile esetshenziswa kumaphrojekthi abalulekile nasezindaweni ezibalulekile, ukuhlolwa kokushisa kokushisa kungenziwa kuqala.
Ukuhlolwa kwe-Heat soak kwaziwa nangokuthi ukwelashwa okulinganayo, okuvame ukwaziwa ngokuthi "ukuqhunyiswa".ingilazi yokucwilisa eshisayo. Ukuhlolwa kokucwilisa ukushisa ukushisa ukushisaingilazi epholilekuya ku-290℃±10℃ "esithandweni se-homogenizing", futhi uyibambe isikhathi esithile, ukuze i-nickel sulfide (NiS) engilazini epholile iqedele ukuguqulwa kwesigaba se-crystal ukusheshisa inqubo yayo yokwandisa, ukuze isetshenziswe ekuqaleni. ngemuva kokuthi ingilazi epholile ingaqhuma ngokuzenzakalelayo kusenesikhathi efektri "i-homogenizing furnace", Ngakho-ke kuncishiswe ukusetshenziswa kwengilazi epholile ngemuva kokufakwa kokuziqhumisa, ukuphepha okwandisiwe. Ngemuva kokuhlolwa kokucwiliswa kokushisa, izinga lokuziqhumisa lengilazi efudumele lingancishiswa libe cishe elilodwa kwabayi-10,000, kodwa ukuhlolwa kwe-heat soak akuqinisekisi ukuthi ingilazi epholile ayenzi ukuziqhumisa ngokwayo, kodwa kunciphisa kuphela ukwenzeka kokuziqhumisa. , futhi empeleni ixazulula inkinga yokuziqhumisa ehlasele zonke izinhlangothi kuphrojekthi. Ngakho-ke, ukuhlolwa kwe-heat soak kuyindlela ephumelela kakhulu yokuxazulula inkinga yokuziqhumisa ngaphansi kwezimo zamanje zobuchwepheshe eziqashelwa ngazwi linye emhlabeni.
Izinzuzo ukushisa cwilisa ingilazi omnene
Izinga lokuziqhumisa eliphansi: ngokwezibalo, izinga lokuziqhumisa lengilazi efudumele enokuhlolwa kokucwilisa ukushisa ngokuqinile ngokwenqubo lingancishiswa lisuka ku-0.3% liye ku-0.01%, liphansi kakhulu kunezinga lokuziqhumisa lengilazi evamile.
Ukuphepha okwengeziwefuthiukunciphisa izindleko zokulungisa nokulungisa kamuva: ngenxa yezinga eliphansi lokuziqhumisa, nciphisa ingozi ebangelwa ukuziqhumisa kwengilazi epholile, futhi unciphise kakhulu izindleko zokuziqhumisa kwengilazi eqinile ukuze kuvikelwe kangcono ingilazi.
