Corrosion ib txwm yog qhov kev txhawj xeeb tseem ceeb cuam tshuam rau kev nyab xeeb thiab kev pabcuam lub neej ntawm cov kav hlau ua haujlwm thaum siv kev thauj mus los thiab siv. Xaiv txoj cai anti - corrosion txheej khoom yog vim li no qhov tseem ceeb kom ntseeg tau ntev- lub sijhawm ua haujlwm. Tam sim no, feem ntau siv cov txheej txheej muaj xws li kuab kuab-}} - shrinkable tsho.
Hnyav -} Dawb epoxy Txheej Txheem: Txhim Kho thiab ruaj khov
Hnyeeb -}} Txheej Txheem Dawb Epoxy tau siv dav rau kev tiv thaiv sab hauv thiab sab nraud ntawm cov kav hlau loj. Tom qab kho, lawv tsim cov tuab, tawv tawv nrog cov nplaum zoo, rwb thaiv tsev, thiab corrosion tsis kam. Tsis zoo li ib txwm txheej txheej, daws -} Dawb epoxy tsis emefer thiab muaj kev nyab xeeb dua qub. Nws zaj duab xis {{5 5}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}},,, nrog ib tuab ntawm ntau dua 200 lub sijhawm uas tsis muaj pinholes. Cov txheej txheem kho tau kuj tseem pom cov kev cuam tshuam tsis kam, tev lub zog, thiab kev ua tau zoo, txuas ntxiv rau cov yeeb nkab lub neej.
3Pe anti {{- corrosion: Zog- - tus phooj ywg
Rau kev tiv thaiv kev tiv thaiv thiab kev ceev, 3Pe anti - Cov txheej txheem corrosion tau dhau los ua cov phiaj xwm pipeline loj. Tus qauv suav nrog epoxy primer, ib qho nplaum txheej nruab nrab, thiab polyethylene sab nraud txheej, ua kom sib xyaw ua ke lub zog, rwb thaiv tsev, thiab tshuaj lom neeg kuj. Cov txheej txheej no tshwj xeeb yog tsim nyog rau cov roj, roj, thiab cov pa roj One} PE tsis tsuas yog siv cov pa hluav taws xob zoo thiab ua rau muaj kev pabcuam zoo rau lub zog thiab ib puag ncig cov ntawv thov.
Txias -}}} {-} shrinkle tapes: hloov tau rau ntau yam kev mob
Hauv chaw tsim tshwj xeeb chaw ua haujlwm, txias-}} hom cua sov- hom cua sov} Cov ntaub ntawv no yog yoog tau thiab tau tshaj nrog cov khoom sib txawv steel yeeb. Txias -}}}}}}}}}}}}}}}}}}}}}}}}} Kev siv waterproof zoo, txawm hais tias lawv zoo li tsis muaj zog rau ib puag ncig. Thaum tshav kub kub - shrinkle tsho, ntawm qhov tod tes tiv thaiv thiab muaj zog tiv thaiv los ntawm shrinking thaum rhuab, ua ib lub tuam txhab khov kho ib ncig ntawm cov yeeb nkab.
Epoxy Hmoov Txheej: Muaj zog adhesion nrog kev txwv
Epoxy hmoov txheej ua tiav siv cov electrostatic txau, tsim kev sib raug zoo ntawm cov txheej thiab cov yeeb nkab nto. Cov txheej txheej no muaj cov adhesion zoo thiab corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv nruab nrab lossis mob acidic ib puag ncig. Txawm li cas los xij, lawv tsis zoo tagnrho rau dej kav dej vim yog lawv tus nqi nqus dej siab (nce txog 0.83%) thiab cov dej tsis zoo. Ib qho ntxiv, daim teb yuav tsum muaj qhov tseeb tswj thiab kev ua haujlwm, ua kom muaj kev ua kom muaj kev sib tw ntau dua.
Hauv cov ntsiab lus, xaiv ib qho anti - corrosion txheej rau cov kav hlau, kev tsim kho cov kev tsim kho ib puag ncig, thiab cov kev xav tau tshwj xeeb. Nrog rau kev nce qib tsis tu ncua, anti - Cov kev daws teeb meem corrosion yuav txuas ntxiv mus ntxiv, muab kev pab ntau dua rau cov pipelines hla ntau yam lag luam.
