Raws li tib neeg them nyiaj ntau thiab ntau dua rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov, kev siv cov kav dej hauv ntau qhov kev lag luam thiab cov teb tau dhau los ua ib txwm muaj.Txawm li cas los xij, cov kav dej feem ntau raug cuam tshuam rau qhov chaw hnyav, xws li kub, kub siab, thiab corrosive media, ua rau kev puas tsuaj loj heev rau lawv, ua rau cov nqi kho mob ntau dua thiab, qee zaum, muaj xwm txheej lossis kev puas tsuaj ib puag ncig.Yuav kom kov yeej cov kev cov nyom no, cov kav dej tuaj yeem raug coated nrog cov txheej txheem tiv thaiv xws li3 LPE coatingsthiab FBE txheej los ua kom lawv cov corrosion kuj thiab txhim kho lawv cov kav ntev.
3Lpe txheej, uas yog, peb-txheej polyethylene txheej, yog ntau txheej txheej txheej txheem sib xyaw epoxy (FUEEN-txheej txheej, ib txheej nplaum thiab cov polyethylene soscoat txheej.Cov txheej txheem txheej txheem muaj kev tiv thaiv corrosion zoo heev, txhua yam muaj zog thiab cuam tshuam tsis kam, ua rau nws siv dav hauvroj thiab roj pipelines, cov kav dej thiab lwm yam kev lag luam uas cov kav xa dej raug cuam tshuam rau ib puag ncig corrosive.
FBE txheej, ntawm qhov tod tes, yog ib txheej txheej txheej txheej uas muaj cov thermosetting epoxy hmoov txheej siv rau saum npoo ntawm cov yeeb nkab.Cov txheej txheem txheej txheej tau zoo heev adhesion, siab abrasion thiab cuam tshuam tsis kam thiab tshuaj lom neeg zoo, ua rau nws tsim nyog rau kev tiv thaiv cov kav dej hauv ntau yam lag luam xws li roj thiab roj, dej thiab kev thauj mus los.
Ob leeg 3LPE txheej thiab FBE txheej yog dav siv nyob rau hauv pipeline engineering vim lawv cov khoom tiv thaiv zoo heev.Txawm li cas los xij, lawv qhov peev txheej ntawm daim ntawv thov sib txawv nyob ntawm qhov xwm txheej tshwj xeeb uas cov kav dej yuav tsum tau ua.
Hauv cov roj thiab cov kav dej, 3LPE txheej yog nyiam dua vim tias nws tuaj yeem tiv taus cov roj thiab roj, nrog rau kev cuam tshuam thiab kev sib txhuam ntawm cov av ib puag ncig.Tsis tas li ntawd, 3LPE coatings kuj tuaj yeem tiv thaiv cathodic disbonding, uas yog kev sib cais ntawm cov txheej txheem ntawm cov hlau vim yog cov tshuaj electrochemical.Qhov no yog qhov tshwj xeeb tshaj yog rau cov kav dej uas muaj cathodically tiv thaiv corrosion.
In cov kav dej, FBE txheej yog thawj qhov kev xaiv vim nws tuaj yeem tiv thaiv kev tsim ntawm biofilm thiab kev loj hlob ntawm cov kab mob, uas tuaj yeem ua rau cov dej tsis zoo.FBE txheej kuj tseem tsim nyog rau cov kav dej xa cov xov xwm abrasive, xws li xuab zeb, gravel lossis av nkos, vim nws hnav tsis kam.
Hauv kev thauj mus los, 3LPE txheej lossis FBE txheej tuaj yeem siv raws li qhov xwm txheej tshwj xeeb ntawm kev thauj mus los.Yog hais tias lub raj xa dej raug rau ib puag ncig corrosive, xws li ib puag ncig marine, 3LPE txheej yog nyiam vim tias nws tiv taus cov dej hiav txwv thiab cov kab mob marine.Yog tias cov yeeb nkab raug rau cov xov xwm abrasive xws li cov ntxhia los yog ore, FBE txheej yog qhov zoo dua vim nws tuaj yeem muab kev hnav zoo dua li 3LPE txheej.
Txhawm rau ua kom tiav, Scope ntawm daim ntawv thov ntawm 3LPE txheej thiab FBE txheej sib txawv raws li cov xwm txheej tshwj xeeb ntawmpipeline engineering.Ob txheej txheej txheej txheem muaj lawv tus kheej qhov zoo thiab qhov tsis zoo.Kev xaiv cov txheej txheem txheej txheej yuav tsum ua tib zoo xav txog ntau yam xws li qhov nruab nrab ntawm qhov nruab nrab, qhov kub thiab qhov siab ntawm cov kav dej, thiab qhov chaw ib puag ncig.Nrog rau kev txhim kho txuas ntxiv ntawm cov kav dej thev naus laus zis, peb ntseeg tias yuav muaj cov txheej txheem tshiab thiab muaj txiaj ntsig zoo kom tau raws li cov kev xav tau loj hlob ntawm kev tiv thaiv cov kav dej thiab kev nyab xeeb.
Peb tau txais lub Hoobkas los tiv thaiv corrosion uas tuaj yeem ua 3PE txheej, epoxy txheej thiab lwm yam.Yog tias muaj lus nug thov hu rau peb.
