Dab tsi yog qhov corrosion kuj ntawm zirconium tubular tshav kub exchangers

Zirconium tubular tshav kub exchangers yog renowned rau lawv exceptional corrosion kuj, uas ua rau lawv indispensable nyob rau hauv hnyav industrial cheeb tsam. Lawv cov tshuaj tiv thaiv-corrosive kev ua tau zoo tshwm sim los ntawm ntau yam ntawm sab hauv thiab sab nrauv, raws li tau piav qhia hauv qab no.

1.Kev tsim cov zaj duab xis passive oxide.
Zirconium readily reacts with oxygen in the air or aqueous environments to form a dense, adherent and stable oxide film on the surface. Cov yeeb yaj kiab no ua raws li kev tiv thaiv zoo uas tiv thaiv cov hlau hauv qab los ntawm kev sib cuag ncaj qha nrog cov xov xwm corrosive, yog li inhibiting ntxiv oxidation thiab corrosion. oxide zaj duab xis yog tus kheej - kho; yog khawb los yog puas nyob rau hauv me me tej yam kev mob, nws muaj peev xwm sai sai regenerate kom rov qab muaj kev tiv thaiv nyhuv.

2.Resistance rau muaj zog acids.
Tsis zoo li ntau hom hlau, zirconium nthuav tawm kev ruaj ntseg zoo kawg nkaus hauv ntau cov kua qaub. Nws tuaj yeem tiv taus corrosion ntawm hydrochloric acid, sulfuric acid, nitric acid thiab phosphoric acid ntawm qhov sib txawv thiab qhov kub thiab txias. Txawm hais tias nyob rau hauv cov ntsiab lus siab thiab siab heev -kub acid daws, cov zaj duab xis passive ntawm zirconium nto tseem zoo, tsis txhob muaj corrosion hnyav xws li pitting los yog kev sib cais uas feem ntau tshwm sim hauv lwm cov ntaub ntawv.

3.Kev ua siab ntev rau kev tawm tsam tshuaj lom neeg.
Tshaj li cov kua qaub muaj zog, zirconium tubular cua kub exchangers kuj ua tau zoo nyob rau hauv corrosive ib puag ncig uas muaj halides, oxidants thiab organic acids. Lawv tiv taus corrosion los ntawm cov tshuaj chlorine, fluorine thiab lawv cov tebchaw, uas muaj kev txhoj puab heev rau feem ntau cov hlau. Cov cuab yeej no ua rau lawv tsim nyog rau kev siv hauv cov txheej txheem tshuaj lom neeg uas muaj halogenated hydrocarbons lossis fluorinated chemicals.

4.Stability nyob rau hauv txawv kub thiab siab tej yam kev mob.
Lub corrosion kuj ntawm zirconium tsis deteriorate heev nyob rau hauv kev khiav hauj lwm kub thiab siab ntau yam uas feem ntau ntsib nyob rau hauv industrial tshav kub pauv txheej txheem. Txawm tias nyob rau hauv siab - kub thiab siab - ib puag ncig siab, oxide zaj duab xis tuav nws cov qauv kev ncaj ncees, thiab cov hlau nws tus kheej tsis ua kom pom tseeb corrosion degradation, kom ntseeg tau ntev - lub sij hawm ruaj khov ntawm lub tshav kub exchanger.

5.Resistance rau crevice thiab pitting corrosion.

Crevice thiab pitting corrosion yog hom tsis ua haujlwm rau ntau cov hlau hauv corrosive media, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj chloride ions. Zirconium tubular tshav kub exchangers muaj zog tiv thaiv cov ntaub ntawv nyob rau hauv lub zos corrosion vim lub uniform thiab ntom ntawm lawv passive zaj duab xis. Qhov no tiv thaiv kev puas tsuaj hauv cheeb tsam uas tuaj yeem ua rau tsis ua haujlwm ntxov ntxov ntawm cov hlab cua sov.

6.Compatibility nrog aqueous thiab tsis yog - aqueous systems.
Zirconium tuav zoo heev corrosion kuj nyob rau hauv ob qho tib si aqueous thiab non{0}}aqueous corrosive systems. Txawm hais tias hauv dej-raws li kev daws teeb meem nrog cov ntsiab lus ntsev, xws li dej hiav txwv lossis dej hiav txwv, lossis hauv cov dej tsis huv xws li cov kuab tshuaj organic sib xyaw nrog cov khoom siv corrosive, zirconium tubular heat exchangers tuaj yeem ua haujlwm ruaj khov yam tsis muaj kev cuam tshuam loj, nthuav dav lawv daim ntawv thov thoob plaws ntau hom kev lag luam.

Nyob rau hauv cov ntsiab lus, corrosion kuj ntawm zirconium tubular tshav kub exchangers yog ib qho kev nthuav qhia ntawm lawv cov khoom, cov yam ntxwv ntawm cov yeeb yaj duab nto thiab compatibility nrog ntau yam xov xwm. Qhov kev ua tau zoo tshaj no ua rau lawv ua haujlwm tau zoo hauv qhov chaw hnyav hnyav uas lwm cov ntaub ntawv yuav ua tsis tau sai.
