Ko kupatsanurwa kwepombi dzesimbi isina tsvina kunobvepi?

Inpombi dzesimbi dzisina tsvina, simbi inoshingirira mukuora nemidziyo isingakure yakaita semhepo, chiutsi, nemvura, uye zvinhu zvinoparadza makemikari zvakaita seasidhi, alkali, uye munyu, inonziwo simbi isina asidi.Mumashandisirwo anoshanda, masimbi anoshingirira kune zvisina kusimba mukuodza media anowanzo kunzi simbi isina simbi, uye simbi inoshingirira kumakemikari media inodaidzwa sesimbi isingaite acid.Nekuda kwemusiyano wekuumbwa kwemakemikari pakati pezviviri izvi, yekutanga haigoni kurwisa corrosion nemakemikari media, nepo ekupedzisira kazhinji asina tsvina.

Chechipiri, kushorwa kwepombi yesimbi isina tsvina kunoenderana nealloying zvinhu zviri musimbi.Chromium ndicho chinhu chakakosha chesimbi isina simbi kuti iwane corrosion resistance.Kana zviri mukati mechromium musimbi zvinosvika 1.2%, chromium inodyidzana nekuora.Mhedzisiro yeokisijeni muchinhu inoumba firimu yakaonda oxide pamusoro pesimbi, iyo inogona kudzivirira kuparara kwesimbi.Iyo substrate inowedzera kusvibiswa.Kuwedzera kune chromium, inowanzoshandiswa alloying zvinhu nickel, molybdenum, titanium, niobium, mhangura, nitrogen, etc. kuzadzisa zvinodiwa siyana mafomu pamusoro chimiro uye ehupfumi simbi isina tsvina.
