Insimbi Engagqwali: Into Ebalulekile Yemboni Yesimanje Nempilo

Insimbi engagqwali iyingxubevange eyakhiwe ngokuyinhloko ngensimbi, kanye nokwengezwa kwe-chromium (imvamisa Inkulu noma ilingana no-10.5%), i-nickel, nezinye izakhi ze-alloying. Isici sayo esiphawuleka kakhulu ukumelana kwayo nokugqwala okukhethekile.

Lesi sakhiwo sisuka kufilimu eminyene ye-chromium oxide passivation eyakha phezulu, ihlukanisa ngokuphumelelayo umoya-mpilo nomswakama, ivimbele ukuqhubekela phambili kwe-oxidation yensimbi eyisisekelo. Ngokusekelwe esakhiweni sayo se-metallographic, insimbi engagqwali ingahlukaniswa njenge-austenitic (efana no-304 no-316), i-ferritic (efana no-430), i-martensitic (efana no-440C), nensimbi eyi-duplex, ngayinye ifanele ukusetshenziswa okuhlukile.

Mayelana nokusebenza, insimbi engagqwali ihlanganisa amandla aphezulu,{0}}ukumelana nezinga lokushisa eliphezulu, kanye nokusebenza kalula komshini. Insimbi engagqwali ye-Austenitic, ngenxa-yokungeyona intokazibuthe kanye ne-ductility enhle kakhulu, isetshenziswa kakhulu ezintweni zokudla nasezitsheni zamakhemikhali. Insimbi ye-Martensitic, efinyelela ubulukhuni obukhethekile ngemva kokwelashwa kokushisa, ivame ukutholakala kumathuluzi okusika nama-bearings. I-Molybdenum-equkethe insimbi engu-316, ngenxa yokumelana kwayo ne-asidi nokugqwala kwe-alkali, iyinketho ekhethwayo yobunjiniyela basolwandle kanye nezimila zezokwelapha.

Insimbi engagqwali isetshenziswa emikhakheni eminingi emphakathini wanamuhla. Embonini yezokwakha, insimbi engagqwali isetshenziswa ezakhiweni zokuhlobisa njengezindonga zamakhethini nama-handrails. Embonini yokukhiqiza, imishini yamakhemikhali namapayipi okukhipha umoya wezimoto kuncike ekumelaneni nokugqwala kwawo. Empilweni yansuku zonke, insimbi engagqwali nayo isetshenziswa kabanzi kuma-kitchenware nasezindlini zasendlini. Ngaphezu kwalokho, ukugaywa kabusha kwayo okungu-100% kuhlangabezana nezidingo zentuthuko esimeme, ngezinga lomhlaba jikelele lokuphinda lisetshenziswe lingaphezu kwama-60%.

Ngokuthuthuka kwezobuchwepheshe, izinto ezintsha ezifana ne-super stainless steel (ezifana ne-duplex steel 2205) kanye nensimbi engagqwali elwa namagciwane ziyavela, ziqhubeke zandisa imingcele yokusetshenziswa kwayo. Kusukela kumishini yezimboni kuya ezintweni zansuku zonke, insimbi engagqwali, nokusebenza kwayo okulinganiselayo nokusebenza kahle kwezomnotho, iyaqhubeka nokunikeza ukusekelwa okubalulekile ekuthuthukisweni komuntu.
