Ngokuthuthuka okuqhubekayo kwemboni yokukhiqiza insimbi, izinto zensimbi engagqwali zithole ukusetshenziswa okubanzi ekuphileni kwansuku zonke, ukukhiqizwa kwezimboni, kanye nezinkundla zempi.Ngesikhathi sokucutshungulwa, ukwenziwa, kanye nokusetshenziswa kwensimbi engagqwali, indawo yayo engaphezulu ingase ibonise amabala ombala angalingani noma imikhondo yokugqwala ngenxa ye-oxidation yezinga lokushisa eliphezulu, ukugqwala okumaphakathi, njll. Ngezizathu zobuhle noma ukulungisa lezi zinkinga,insimbi engagqwali picklingfuthiizixazululo ze-passivationzivame ukusebenzela ukuhlanza amakhemikhali kanye nokwelapha passivation.Le nqubo yakha ifilimu ye-passive ephelele nefanayo endaweni, ethuthukisa ubuhle bezinto ezibonakalayo nokumelana nokugqwala, futhi inwebe isikhathi sempilo yensimbi engagqwali.
Ngaphambi kokusebenzisa insimbi engagqwali pickling kanye nekhambi le-passivation ezingxenyeni ezishiselwe, indawo yensimbi engagqwali idinga ukucoliswa, ukususwa kokungcola, nokupholishwa.Bese, uthele i-isixazululo passivationungene esitsheni sepulasitiki bese usisebenzisa ngokuya ngezinto zensimbi engagqwali kanye nobukhulu be-oxidation.Beka izinto zokusebenza esixazululweni, ngokujwayelekile ezingeni lokushisa legumbi, bese uzicwilise imizuzu emi-5-20 noma ngaphezulu (isikhathi esikhethekile nezinga lokushisa kuzonqunywa umsebenzisi ngokusekelwe kuzimfuneko zakhe ezithile).Susa ama-workpieces ngemva kokususwa okuphelele kokungcola okungaphezulu, lapho ubuso bubonakala ngokufana kwesiliva-mhlophe.Ngemuva kokuvuna kanyeukuthatheka, hlambulula izinto zokusebenza kahle ngamanzi ahlanzekile bese uzisula.
