Insimbi engagqwali inamandla okugqwala phakathi nendawo equkethe i-asidi, i-alkali nosawoti, okungukuthi ukumelana nokugqwala; Futhi inamandla okumelana ne-oxidation yasemkhathini, okungukuthi, ukugqwala; Kodwa-ke, ubukhulu bokumelana kwayo nokugqwala buyahlukahluka ngokwakhiwa kwamakhemikhali ensimbi ngokwayo, izimo zokusetshenziswa kanye nohlobo lwemidiya yemvelo. Njengensimbi engagqwali engu-304, endaweni eyomile nehlanzekile inokumelana nokugqwala okuhle kakhulu, kodwa lapho ithuthelwa endaweni yolwandle, izogqwala ngokushesha enkungu yolwandle equkethe usawoti omningi; Izinto ezingama-316 zinokusebenza okuhle. Ngakho kunoma iyiphi imvelo akulona uhlobo insimbi engagqwali abakwazi ukugqwala.
Indawo yensimbi engagqwali yakha ungqimba lwefilimu ye-chromium oxide ezacile kakhulu futhi eqinile, bese ithola amandla okumelana nokugqwala. Kanye ngesizathu esithile, le filimu ihlale ilimele. Ama-athomu e-oksijeni emoyeni noma uketshezi luzoqhubeka nokungena noma ama-athomu ensimbi ensimbi azoqhubeka nokuhlukana, ukwakheka kwe-iron oxide evulekile, ubuso bensimbi buyohlala bugqwalile, ifilimu yokuzivikela yensimbi engenasici izobhujiswa.
Izigameko ezimbalwa ezivamile zokugqwala kwensimbi engagqwali ekuphileni kwansuku zonke
Ingaphezulu lensimbi engagqwali liye lanqwabelana uthuli, oluqukethe okunamathiselwe kwezinye izinhlayiya zensimbi. Emoyeni onomswakama, amanzi e-condensate phakathi kokunamathiselwe kanye nensimbi engagqwali azoxhuma kokubili ku-microbattery, ngaleyo ndlela kubangele ukusabela kwe-electrochemical, ifilimu yokuzivikela iyabhujiswa, ebizwa ngokuthi i-electrochemical corrosion; Ingaphezulu lensimbi engagqwali linamathela kujusi wemvelo (njengamakhabe nemifino, isobho lenoodle, i-phlegm, njll.), futhi lakha ama-asidi e-organic esimweni samanzi nomoya-mpilo.
Ingaphezulu lensimbi engagqwali lizonamathela ku-asidi, i-alkali, izinto zikasawoti (njenge-alkali yokuhlobisa odongeni, i-lime splash), okuholela ekugqwaleni kwendawo; Emoyeni ongcolile (njengomkhathi oqukethe inani elikhulu le-sulfide, i-carbon oxide ne-nitrogen oxide), i-sulfuric acid, i-nitric acid ne-acetic acid izokwakheka lapho kuhlangana namanzi ajiyile, ngaleyo ndlela kubangele ukugqwala kwamakhemikhali.
Zonke lezi zimo ezingenhla zingalimaza ifilimu evikelayo ebusweni bensimbi engagqwali futhi kubangele ukugqwala. Ngakho-ke, ukuze kuqinisekiswe ukuthi indawo yensimbi ikhanya futhi ayigqwalile, sincoma ukuthi indawo yensimbi engagqwali kufanele ihlanzwe futhi ikhuhlwe ukuze kukhishwe okunamathiselwe futhi kuqedwe izici zangaphandle. Indawo yolwandle kufanele isebenzise insimbi engagqwali engu-316, impahla engu-316 ingamelana nokugqwala kwamanzi olwandle; Enye ipayipi yensimbi engagqwali ukwakheka kwamakhemikhali emakethe ayikwazi ukuhlangabezana nezindinganiso ezihambisanayo, ayikwazi ukuhlangabezana nezidingo zezinto ezingu-304, futhi izobangela ukugqwala.
