Yuav ua li cas xaiv lub twj tso kua mis tus kheej rau kev tshaj tawm uas muaj Cl⁻

Rau cov tshuaj chlorine uas muaj cov dej khib nyiab, kev xaiv cov khoom siv ntawm lub twj tso kua mis yog qhov tseem ceeb heev vim tias cov tshuaj chloride ions tuaj yeem ua rau corrosion rau cov khoom siv twj tso kua mis. Cov hauv qab no yog qee cov khoom siv twj tso kua mis tsim nyog rau cov tshuaj chlorine uas muaj cov dej khib nyiab:

Stainless hlau tus kheej nqus twj tso kua mis: Stainless hlau yog cov khoom siv corrosion-resistant haum rau chlorine uas muaj dej khib nyiab. Ntawm lawv, 304 thiab 316 stainless hlau yog cov khoom siv feem ntau. 304 stainless hlau yog tsim rau cov concentration chloride ion ib puag ncig, thaum 316 stainless hlau yog haum rau siab concentration chloride ion ib puag ncig. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias kev tiv thaiv corrosion ntawm stainless hlau yog cuam tshuam los ntawm cov yam ntxwv xws li kub, concentration, thiab ntws tus nqi.

Fluorine yas tus kheej nqus twj tso kua mis: fluorine yas yog cov khoom siv zoo heev corrosion-resistant uas tuaj yeem tiv taus kev yaig ntawm cov tshuaj chloride ions thiab muaj zog acids thiab alkalis. Yog li ntawd, fluoroplastic twj tso kua mis tsim nyog rau kev kho cov tshuaj chlorine uas muaj cov dej khib nyiab.

Hastelloy self-priming twj tso kua mis: Hastelloy kuj yog cov khoom siv tiv thaiv corrosion, tshwj xeeb tshaj yog haum rau cov chaw muaj tshuaj chloride ion. Txawm li cas los xij, tus nqi ntawm HC / HB alloy yog qhov siab, yog li xav tau kev txiav txim siab zoo thaum xaiv.

Thaum xaiv cov khoom siv ntawm cov tshuaj chlorine uas muaj cov twj siv dej khib nyiab, nws yuav tsum ua tib zoo xav txog cov xwm txheej tshwj xeeb ntawm cov dej khib nyiab, nrog rau cov khoom xws li chloride ion concentration, kub, ntws tus nqi, thiab lwm yam. Tsis tas li ntawd, yam xws li twj tso kua mis kev ua tau zoo thiab kev lag luam. cov txiaj ntsig yuav tsum tau txiav txim siab xaiv cov khoom siv twj tso kua mis uas tsim nyog tshaj plaws. Nws raug nquahu kom sab laj tus kws tshaj lij engineer lossis tus neeg muag khoom thaum xaiv lub twj tso kua mis kom tau txais cov lus qhia ntxaws thiab raug.
