1.Yuav ua li cas ua tau zoo npaum li cas txias - dov carbon steels nyob rau hauv resisting acids thiab alkalis?
Lub substrate yog carbon steel, uas yog inherently susceptible rau corrosion los ntawm acids thiab alkalis. Cov kua nplaum uas nyob ntawm kev ua haujlwm (xws li cov kua qaub lossis alkaline leveling daws) tuaj yeem tsim cov pob txha ntawm cov phaj.
Nws tsuas yog tsim nyog rau qhov qhuav, tsis yog -corrosive nyob rau hauv ib puag ncig thiab yuav tsum tsis txhob nkag mus rau hauv cov kua qaub los yog alkalis.
2.Yuav ua li cas tiv taus txias- dov stainless hlau coils rau acids thiab alkalis?
Muaj cov ntsiab lus alloying xws li chromium thiab npib tsib xee, nws tuaj yeem tsim cov chromium tuab -nplua nuj oxide zaj duab xis (passivation zaj duab xis) ntawm nws qhov chaw, ua rau nws ruaj khov nyob rau hauv ntau yam corrosive media (xws li acids thiab alkalis).
Siv dav hauv tshuaj, khoom noj, kev kho mob thiab lwm yam kev lag luam nrog cov kev cai tshwj xeeb rau cov kua qaub thiab alkali tsis kam.
3.Yuav ua li cas zoo npaum li cas yog cov kua qaub thiab alkali tsis kam ntawm corrosion tshwj xeeb - tiv taus txias - dov steel?
Los ntawm kev ntxiv cov ntsiab lus alloying tshwj xeeb (xws li tooj liab thiab antimony), nws yog tsim tshwj xeeb los tiv thaiv corrosion los ntawm cov xov xwm tshwj xeeb (xws li hydrochloric acid thiab sulfuric acid).
Siv nyob rau hauv tshwj xeeb tshuaj ib puag ncig xws li tshav kub exchangers thiab flues.
4.Yuav ua li cas cov kua qaub thiab alkali tsis kam ntawm coated / plated txias-rolled steel?
Corrosive media yog cais los ntawm txheej txheej ntawm cov khaub thuas zoo tib yam- cov ntawv yob steel nrog cov organic txheej lossis plating (xws li PVC txheej koj tau nug yav dhau los). Txawm li cas los xij, cov kua qaub thiab alkali tsis kam ntawm txheej yog qhov txwv ntawm nws qhov kev ua tau zoo.
Haum rau kev siv hauv kev tsim kho, khoom siv hauv tsev, thiab lwm yam uas xav tau kev tiv thaiv corrosion.
5.Dab tsi yog tus yuam sij rau acid thiab alkali tsis kam?
Khoom siv nws tus kheej: Ib yam li peb tsis tuaj yeem cia siab tias yuav muaj cov ntawv hlau zoo tib yam los tuav cov kua qaub, cov tshuaj muaj pes tsawg leeg ntawm cov khaub thuas zoo tib yam -rolled carbon steel txiav txim siab tias nws tsis tuaj yeem tiv taus acid thiab alkali corrosion.
Kev tiv thaiv nto: Alloying (ua stainless hlau) los yog ntxiv txheej tuaj yeem txhim kho nws cov kua qaub thiab alkali tsis kam. Piv txwv li, passivated stainless hlau muaj ib tug thicker, ruaj khov tiv thaiv zaj duab xis ntawm nws nto, ua rau muaj zog corrosion kuj.
