Yuav ua li cas yog corrosion kuj ntawm zirconium tshav kub exchanger reflected

Kev tiv thaiv corrosion ntawm zirconium tshav kub exchanger feem ntau yog tshwm sim hauv cov hauv qab no:
Corrosion tsis kam rau inorganic acid:
Hydrochloric acid: Zirconium muaj kev tiv thaiv zoo heev hauv hydrochloric acid. Txawm tias nyob rau hauv high-concentration hydrochloric acid, zirconium tshav kub exchanger muaj peev xwm tswj tau zoo stability nyob rau hauv ib tug tej yam kub kub. Nyob rau hauv ib puag ncig hydrochloric acid, ib tug ntom oxide zaj duab xis yuav tsim nyob rau saum npoo ntawm zirconium, uas yuav tiv thaiv hydrochloric acid los ntawm ntxiv corroding zirconium cov ntaub ntawv, yog li tiv thaiv lub tshav kub exchanger los ntawm corrosion.
Sulfuric acid: Rau sulfuric acid nruab nrab, zirconium tshav kub exchanger kuj qhia tau zoo corrosion kuj. Nyob rau hauv dilute sulfuric acid los yog nruab nrab-concentration sulfuric acid tov, zirconium tuaj yeem nyob ruaj khov, thiab nrog kev nce ntawm sulfuric acid concentration, corrosion kuj ntawm zirconium yuav txo qis, tab sis ntau zaus nws tseem zoo dua li lwm cov khoom siv hlau. Qhov no yog vim hais tias cov sulfate compound tsim los ntawm cov tshuaj tiv thaiv ntawm zirconium thiab sulfuric acid muaj ib qho kev ruaj ntseg thiab tuaj yeem ua raws li qhov chaw ntawm zirconium, ua si lub luag haujlwm tiv thaiv.
Nitric acid: Nyob rau hauv ib puag ncig nitric acid, zirconium tshav kub exchanger kuj muaj zoo kam rau ua. Txawm hais tias nws yog dilute nitric acid los yog concentrated nitric acid, zirconium tuaj yeem tiv taus nws cov corrosion. Txawm li cas los xij, nyob rau hauv qhov kub thiab txias siab ntawm nitric acid tej yam kev mob, corrosion kuj ntawm zirconium yuav cuam tshuam rau qee yam, tab sis piv nrog lwm cov hlau, nws cov corrosion kuj tseem zoo heev.
Phosphoric acid: Nyob rau hauv phosphoric acid tov, zirconium muaj corrosion kuj zoo thiab tuaj yeem hloov mus rau qhov chaw corrosive thaum lub sij hawm tsim khoom thiab siv phosphoric acid. Qhov no ua rau zirconium tshav kub exchangers dav siv nyob rau hauv phosphoric acid kev lag luam, xws li nyob rau hauv cov txheej txheem ntawm phosphoric acid concentration thiab txias.
Corrosion tsis kam mus rau alkali muaj zog: Zirconium kuj muaj qee yam corrosion kuj rau cov alkalis muaj zog xws li sodium hydroxide thiab potassium hydroxide. Nyob rau hauv cov tshuaj alkali muaj zog, oxide zaj duab xis nyob rau saum npoo ntawm zirconium tuaj yeem ua lub luag haujlwm tiv thaiv thiab tiv thaiv kom muaj zog alkali los ntawm eroding zirconium ntxiv. Txawm li cas los xij, nyob rau hauv qhov kub thiab txias ntawm qhov chaw muaj zog alkali, qhov corrosion kuj ntawm zirconium yuav raug txo, tab sis nws tseem muaj zog tiv taus alkali corrosion ntau dua li cov khoom siv hlau zoo tib yam.
Corrosion tsis kam rau lwm cov xov xwm corrosive:
Hydrofluoric acid: Zirconium muaj peev xwm tswj tau zoo corrosion kuj thaum lub concentration ntawm hydrofluoric acid yog tsawg thiab kub tsis siab. Txawm li cas los xij, zirconium yuav raug corroded rau qee yam raws li qhov siab ntawm hydrofluoric acid lossis kub kub. Yog li ntawd, thaum siv zirconium tshav kub exchangers los kho cov xov xwm uas muaj hydrofluoric acid, nws yog tsim nyog los soj ntsuam thiab xaiv raws li qhov tshwj xeeb concentration thiab kub tej yam kev mob.
Organic teeb meem thiab organic acid: Rau ntau cov organic teeb meem thiab organic acid, zirconium tshav kub exchangers kuj muaj corrosion kuj zoo. Nyob rau hauv cov organic tshuaj, tshuaj thiab lwm yam lag luam, zirconium tshav kub exchangers yuav siv tau los kho cov xov xwm uas muaj cov organic teeb meem thiab organic acid los xyuas kom meej qhov kev vam meej ntawm cov txheej txheem ntau lawm.
