PE txheej, thermosetting epoxy hmoov, cov xim tsis muaj tshuaj lom, kho kom tsim cov txheej txheem siab molecular hnyav hla-txuas cov qauv, nrog rau cov tshuaj tiv thaiv zoo heev thiab cov khoom siv tshuab siab, tshwj xeeb tshaj yog qhov zoo tshaj plaws tiv thaiv thiab adhesion.Cov txheej yog 100% cov khib nyiab, hnyav-dawb, tsis muaj kuab paug, hmoov siv txog li 95%, thiab yog faus steel pipeline zoo tiv thaiv corrosion txheej.
Epoxy hmoov tau siv los siv cov txheej txheem txau electrostatic.Txij li thaum epoxy hmoov Dip txheej txheem teeb meem los ntawm adhesion, epoxy hmoov dip yeej tsis tau siv dav.Nyob rau hauv xyoo tas los no, nrog rau peb tshwj xeeb txiv maj phaub epoxy hmoov dip phosphating ntse tsim thawj capture ntawm adhesion ntawm epoxy hmoov dip txheej txheem teeb meem, epoxy hmoov dip pib los txhawb lub tshiab technology.
PE txheej rau steel yeeb nkab txheej hom, av noo, kub, thiab lwm yam. txiav txim siab dej nqus txheej, txheej thickness nyob rau hauv tib yam kev mob nrog lub txheej raws li ib tug muaj nuj nqi ntawm kuj mus rau nkag.Cov kev tshawb fawb tau pom tias qhov tsim ntawm crosslinked epoxy qee qhov ntawm cov channel, cov channel ntawm cov dej molecules rau hauv epoxy resin muab cov channel.Tuaj txog ntawm lub qhov mus rau hauv cov txheej txheem txheej / hlau interface, cov tshuaj tiv thaiv kev sib txuas nrog cov khoom siv hlau corrosion, txheej txheej no tiv thaiv corrosion khoom hlau thiab cov tshuaj tiv thaiv, cov txheej txheem kuj txo.Raws li ntau thiab ntau corrosive ions ncav cuag lub interface, txheej txheej ntawm corrosion khoom zaj duab xis maj mam raug rhuav tshem, nce corrosion, ua rau epoxy txheej stripped ntawm lub nruas.FBE coatings kho tseem muaj nplua nuj nyob rau hauv ether thiab hydroxyl, cov reactive functional pab pawg neeg los ntawm ib tug tshuaj daim ntawv cog lus nrog cov yeeb nkab nto txheej nrees khi ua ke los tsim ib tug corrosion resistant txheej.Qhib cov txheej, compactness thiab pinholes thiab lwm yam yog vim li cas, muaj ntau yam txheej txheem txheej thiab muaj ib tug dej permeability, yog hais tias muaj ntau cathodic tiv thaiv, cathodic hydrogen evolution, nrog rau cov tsub zuj zuj ntawm nquag hydrogen atoms, mus rau ib tug tej yam, ntawm hydrogen nrog ether pab pawg neeg. thiab cov tshuaj tiv thaiv hydroxyl, yog li ua rau cov adhesion ntawm txheej thiab cov yeeb nkab steel, uas ua rau lub zog adhesion ploj mus.Qhov tshwm sim yog txheej txheej los ntawm cov yeeb nkab tawm.
