Nyob rau hauv lub stainless steel submersible twj tso kua mis nto xeb thaum cov neeg uas coj txawv txawv heev: stainless steel yog tsis xeb, yuav ua li cas xeb nws, nws yog qhov zoo tshaj ntawm stainless steel submersible twj tso kua mis teeb meem. "Nyob rau hauv qhov tseeb, qhov no saib yog tsis ncaj ncees lawm, stainless steel Nyob rau hauv tej yam kev mob yuav tsum rusty.
Lub ntsiab khoom siv ntawm stainless steel yog stainless steel, uas muaj ib tug stainless steel, tab sis kuj nyob rau hauv acid, alkali, ntsev, xeb kuj ntawm lub nruab nrab. Tab sis nws xeb kuj yog cov tshuaj nyob tus yeees ntawm nws steel nws tus kheej, cov kev siv ntawm tej yam kev mob thiab qhov ib puag ncig yog sib txawv. Tsis txhua yam ntawm stainless steel, nyob rau hauv tej chaw muaj peev xwm yuav resistant rau xeb, tsis muaj xeb.
Stainless hlau yog vim nws saum npoo ntawm lub chromium-nplua nuj oxide zaj duab xis, thiaj li los mus tiv thaiv lub txuas ntxiv infiltration ntawm cov pa atoms, tseem mus nrhiav tau lub peev xwm los tiv thaiv corrosion. Tab sis thaum cov zaj duab xis tau lossi muab rhuav pov tseg, cov pa los yog cov kua pa atoms yuav mus ntxiv rau infiltrate los yog hlau hlau atoms ntxiv rau precipitate tawm mus tsim xoob hlau oxide, hlau nto yuav mus ntxiv rau xeb. Qhov no nto zaj duab xis yog puas nyob rau hauv daim ntawv ntawm cov ntau yam, ntau ntau nyob rau hauv txhua txhua hnub lub neej yog cov nram no:
1, stainless steel nto adhesion muaj acid, alkali, ntsev tshuaj (xws li hniav phab ntsa ntawm alkaline dej, txiv qaub dej txaws), yuav ua tau rau lub zos corrosion.
2, stainless steel nto adhesion ntawm organic kua txiv (xws li zaub, kua zaub, hnoos qeev, etc.), nyob rau hauv cov ntaub ntawv ntawm dej thiab oxygen, roos organic acids, lub sij hawm ntev organic acid xeb hlau nto.
3, nyob rau hauv lub kab mob huab cua (xws li muaj ib tug ntau ntawm sulfide, carbon oxides, nitrogen oxide cua), nyob rau hauv cov ntaub ntawv ntawm condensate, tus tsim ntawm sulfuric acid, nitric acid, acetic acid kua taw tes, yuav ua tshuaj rot
dab noj hnub.
4, tus nto ntawm lub stainless steel muaj lwm cov ntsiab ntawm cov hmoov av los yog ua kev hlau hais txuas mus rau lub ntub huab cua, nruab nrab ntawm lub txuas thiab stainless steel condensate, yuav
Lub ob ua ke rau hauv ib lub micro-roj teeb, triggering ib electrochemical cov tshuaj tiv thaiv, tus tiv thaiv zaj duab xis yog puas ntsoog, hu ua electrochemical corrosion.
