Q1: Dab tsi ntawm cov txheej txheej ua tau zoo tshaj rau sab nrauv yeeb tshuaj tiv thaiv?
A1:Fuster-Bonded Epoxy (FBE) Txheej Txheem Adhesion thiab Cathodic Dispers muaj cov khoom pov thawj kev ua haujlwm rau kev tiv thaiv hnyav, tshwj xeeb tshaj yog ntawm txheej Cov kev tsis xws luag . Cov kev siv pleev kab ceramic yog siv rau cov kev xaiv kub (txias
Q2: Yuav ua li cas cathrodic kev tiv thaiv ua haujlwm nrog cov kav dej almox?
A2:Cathodic kev tiv thaiv cov yeeb nkab kom dhau los ua cathode nyob rau hauv ib rectifiers thiab zuaj kev tiv thaiv ntau yam zoo nkauj, thiab siv cov khoom zoo tam sim no {3} Kev saib xyuas Cov chaw nres tsheb kom cov kev tiv thaiv muaj peev xwm nyob hauv cov kev ua tau zoo tshaj plaws ({v vs cu / cuso4 siv electrode) {}}
Q3: Cov kev coj ua zoo tshaj plaws rau kev tswj hwm corrosion hauv alloy?
A3:Tshuaj lom neeg Inhibitors iav-txhawb nqa Epoxy muab kev tiv thaiv ntxiv {6} Kev muag tshuaj corrosion thiab hluav taws xob prevons thiab cov hluav taws xob ntxov muaj cov nqi ua kom ntxov nce ntxiv
Q4: Qhov txiaj ntsig tau zoo npaum li cas hauv cov yeeb nkab tsim?
A4:Corrosion allowances add extra wall thickness (typically 1-3mm) to compensate for expected metal loss. They're cost-effective for predictable, uniform corrosion rates in carbon steel pipes. However, they're ineffective against localized corrosion like pitting or stress corrosion cracking. Allowances must be based on accurate corrosion rate data from similar kev pabcuam cov kab mob . Lawv feem ntau ua ke nrog lwm txoj kev tiv thaiv kev pab cuam tseem ceeb.
Q5: Cov kev txwv ntawm cov kav hlau tsis xeb hauv cov kav corrosion?
A5:Stainless cov hlau nyob twj ywm rau cov chloride kev ntxhov siab ua rau muaj cov oxygride cov kev pab cuam muaj peev xwm tshwm sim hauv kev kho kom huv si hauv kev kho kom sov lossis welded ntu . galvanic corrosion tuaj yeem nrawm nrawm rau cov kev txwv uas yog rau cov khoom siv kom tsim nyog rau cov khoom lag luam
