Thaum lub sij hawm tsim cov txheej txheem ntawm kev lag luam ntawv, ntau yam corrosive media koom nrog, nrog rau cov tshuaj chlorine - muaj cov tshuaj bleaching, acidic thiab alkaline chemical agents, siab -kub chav, thiab ntub chaw. Cov kev xav tau rau corrosion kuj ntawm cov khoom siv yog siab heev. 2205 duplex stainless hlau phaj, nrog nws zoo heev tsis kam mus rau chloride ion corrosion thiab siab zog, tau dhau los ua cov khoom zoo tagnrho xaiv rau cov khoom tseem ceeb hauv kev lag luam ntawv.
Lub steaming thiab pulping system yog ib daim ntawv thov scenario rau 2205 duplex steel. Nyob rau hauv tas li steaming hlab ntsha thiab batch steaming lauj kaub, cov cuab yeej nyob rau hauv ntev kev sib cuag nrog siab -kub alkaline daws thiab sulfide media. Lub tog raj kheej sab hauv thiab cov khoom cua sov ua los ntawm 2205 duplex stainless hlau tuaj yeem tiv taus alkaline corrosion thiab kev ntxhov siab corrosion tawg, cuam tshuam cov khoom siv tu lub voj voog. Lub tshuab loj loj tau hloov 304 stainless hlau nrog 2205 duplex hlau rau cov hlab ntsha, ua rau cov khoom siv lub neej ua haujlwm ntawm 3 xyoos mus rau ntau dua 10 xyoo.
Cov txheej txheem bleaching muaj kev nruj tshwj xeeb rau kev tiv thaiv corrosion ntawm cov ntaub ntawv. Cov tshuaj bleaching siv nyob rau hauv cov txheej txheem no, xws li chlorine dioxide, hypochlorite, thiab hydrogen peroxide, yog heev oxidizing thiab feem ntau muaj chloride ions . 2205 duplex steel, vim nws siab chromium thiab molybdenum cov ntsiab lus, muaj zoo heev tiv taus pitting thiab crevice corrosion, thiab yog dav siv nyob rau hauv bleaching towers, mixers thiab chlorines. Piv nrog rau cov austenitic stainless hlau zoo tib yam, tus nqi corrosion ntawm 2205 duplex steel hauv chlorine - muaj cov tshuaj dawb huv yog txo los ntawm kwv yees li 50%.
Txoj kev thauj mus los thiab kev khaws cia tseem yuav tsum muaj cov khoom siv tiv thaiv corrosion-. Cov raj xa dej, cov tso tsheb hlau luam thiab cov agitators ua los ntawm 2205 duplex stainless hlau daim hlau tuaj yeem tiv taus ob qho tib si tshuaj lom neeg ntawm nruab nrab thiab kev puas tsuaj los ntawm cov pulp ntws. Lawv lub zog tawm los siab tso cai rau cov phab ntsa tuab tuab tsim, txo qhov hnyav thiab tsim cov khoom siv.
Nyob rau hauv cov nqe lus ntawm cov dej cawv dub rov qab, 2205 duplex steel yog siv rau cov khoom siv xws li cov cawv dub evaporators thiab alkali rov qab rauv, zoo tiv thaiv kev sib xyaw ua ke ntawm sulfides thiab chlorides hauv cov cawv dub, ua kom lub sijhawm ntev - kev ua haujlwm ruaj khov ntawm cov txheej txheem rov qab.
