Ngophuhliso oluqhubekayo lweshishini lokuvelisa isinyithi, izinto zensimbi ezingenasici zifumene izicelo ezibanzi kubomi bemihla ngemihla, ukuveliswa kwemizi-mveliso, kunye nemimandla yomkhosi.Ngexesha lokucutshungulwa, ukwenziwa, kunye nokusetyenziswa kwensimbi engenasici, umphezulu wayo unokubonisa amabala ombala angalinganiyo okanye izalathisi zokubola ngenxa ye-oxidation yobushushu obuphezulu, ukubola okuphakathi, njl. Ngenxa yezizathu zobuhle okanye ukujongana nale miba,steel stainless picklingkwayeizisombululo passivationbahlala besetyenziselwa ukucoca imichiza kunye nonyango lwe-passivation.Le nkqubo yenza ifilimu epheleleyo kunye nefanayo kumphezulu, iphucula ubuhle bezinto kunye nokumelana nokubola, kunye nokwandisa ubomi bentsimbi engenasici.
Ngaphambi kokusebenzisa i-pickling yensimbi engenasici kunye nesisombululo se-passivation kwiindawo ezidityanisiweyo, umphezulu wensimbi engenasici kufuneka uhlanjululwe, ukususwa kokungcola kunye nokupolisha.Emva koko, galela iisisombululo sepassivationkwisitya seplastiki kwaye uyisebenzise ngokwezinto zensimbi engenasici kunye nobukhulu be-oxidation.Beka i-workpieces kwisisombululo, ngokuqhelekileyo kwiqondo lokushisa, kwaye ucwilise imizuzu emi-5-20 okanye ngaphezulu (ixesha elithile kunye nokushisa kuya kugqitywa ngumsebenzisi ngokusekelwe kwiimfuno zabo ezithile).Susa i-workpieces emva kokususwa ngokupheleleyo kokungcola komhlaba, xa umphezulu ubonakala ngokufana nesilivere-mhlophe.Emva kokukhetha kunyeukuthandabuza, hlambulula ii-workpieces ngokucokisekileyo ngamanzi acocekileyo kwaye uyomise.
