FBE Txheej: Fusion-bonded epoxy yog ib txheej txheej siv ncaj qha rau cov yeeb nkab steel nto.
Kev tiv thaiv corrosion:
3PE Txheej: Muaj kev tiv thaiv corrosion zoo tshaj vim yog kev sib xyaw ntawm FBE zoo heev adhesion rau hlau thiab txheej txheej polyethylene tsis kam rau ya raws thiab tshuaj.
FBE Txheej: Muab kev tiv thaiv corrosion zoo tab sis tej zaum yuav tsis zoo li 3PE nyob rau hauv ib puag ncig corrosive heev.
Adhesion:
3PE Txheej: Ua kom muaj kev sib raug zoo ntawm FBE txheej thiab cov yeeb nkab steel, txhim kho cov txheej txheem tag nrho.
FBE Txheej: Kuj nthuav tawm zoo adhesion rau hlau, tab sis nws yog ib txheej txheej, uas yuav txwv nws cov kev ua tau zoo hauv qee qhov kev siv.
Daim ntawv thov:
3PE Txheej: Feem ntau siv rau cov kav dej hauv av, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj cov av corrosive thiab hauv cov ntawv thov uas yuav tsum muaj kev tiv thaiv zoo tshaj.
FBE Txheej: Feem ntau yog siv rau cov kav dej uas tsis muaj dej los yog hauv ib puag ncig uas muaj peev xwm corrosion tsawg.
Kub Resistance:
3PE Txheej: tuaj yeem tiv taus ntau qhov kub thiab txias, ua rau nws haum rau qhov chaw txias thiab kub.
FBE Txheej: Feem ntau siv rau hauv cov ntawv thov kub nruab nrab thiab tej zaum yuav xav tau kev rwb thaiv tsev ntxiv rau qhov txias txias lossis kub kub.
Impact Resistance:
3PE Txheej: Cov txheej txheej polyethylene muab qee qhov kev cuam tshuam, ua rau nws tsim nyog rau cov kav dej uas raug rau lub cev muaj zog.
FBE Txheej: Tej zaum yuav muaj kev cuam tshuam qis dua vim nws yog ib txheej txheej txheej.
Kev teeb tsa:
3PE Txheej: Yuav tsum muaj txheej txheem kev thov ntau kauj ruam, uas tuaj yeem ua haujlwm nyuaj thiab siv sijhawm ntau dua piv rau FBE.
FBE Txheej: Yooj yim thiab nrawm dua rau kev thov, uas tuaj yeem txo lub sijhawm teeb tsa thiab tus nqi.
Q: Dab tsi yog tus yam ntxwv ntawm 3PE txheej yeeb nkab?
epoxy txheej yog rau lub ntsiab anticorrosion muaj nuj nqi. Nws muaj kev sib txuas zoo nrog rau saum npoo ntawm cov yeeb nkab steel hlau, cov cuab yeej zoo cathodic disbondment, qhov kub thiab txias ntau ({0}} degree -100 degree ) thiab cov dej tsis zoo.
Cov nplaum txheej yog txuas rau epoxy txheej thiab PE txheej, uas nws lub ntsiab tshuaj muaj pes tsawg leeg yog polyolefin. Lub polyolefin pawg ua haujlwm polar tuaj yeem tsim cov ntawv cog lus hydrogen lossis tshuaj lom neeg nrog epoxy pawg ntawm FBE txheej, ua kom ruaj khov nrog cov txheej hauv qab. Nyob rau tib lub sijhawm, polyolefin's nonpolar ethylene muaj kev sib cuam tshuam nrog PE txheej, kuj tsim cov khoom nplaum zoo nrog lub ntsej muag txheej.
PE txheej muaj cov khoom siv hluav taws xob zoo, tsis muaj dej-absorbing zoo thiab muaj zog tiv thaiv kev puas tsuaj. Cov txheej no tsuas yog muaj kev ua haujlwm ntawm kev tiv thaiv kev tiv thaiv thiab tiv thaiv corrosion.
Yog li 3PE coated yeeb nkab yog ib hom kev sib xyaw ua ke ntawm peb txheej no nrog cov haujlwm sib txawv, ua rau tag nrho cov kab ke nrog txhua txoj haujlwm los tiv thaiv cov kav dej zoo dua.
