Possession corrosion adhesive tepi zvigadzirwa zvinonyanya polyethylene anticorrosion tepi, polypropylene fiber corrosion tepi, 660 PE anti-corrosion tepi, marasha tar epoxy matepi anotonhora, polyethylene anticorrosion tepi uye polypropylene fiber corrosion tepi inosangana neMaximum siyana einjiniya tepi inokwanisa kusangana nemhando dzakasiyana-siyana. .Iyo ine chisungo chakasimba neadhesion inotsigira, kukanganisa kupikisa uye mutambo wakanaka nekuchengetedzwa kwecathodic, muNorth America, South America uye imwe purojekiti yemumba pombi.

Matatu-tier chimiro polyolefin (PE) yakabudirira kuvandudzwa muEurope muma1980s uye kutanga kuishandisa FBE yakanaka anti-corrosion, adhesion, yakakwirira kuramba cathodic disbonding uye yakakwirira kusamira kweiyo polyolefin zvinhu, kuita musanganiswa wezvakanaka zvemuchina uye kuramba. ivhu stress corrosion chimiro, nekuuya kweakawanda einjiniya application, kunyanya munyika dzeEurope, kushandiswa kwayo kwaive kusimuka.Iyo yepasi pedenga PE epoxy coatings, iyo yepakati dhizaini yepolymer adhesive, iyo yepamusoro layer ye polyolefin.Iyo inonamira inogona kugadziridzwa polyolefin, iyo ine polar boka rakabatanidzwa kune polyolefin-kabhoni bond mucheni huru.Saka, iyo inonamira haigone kusanganiswa kwepamusoro-yakagadziridzwa polyolefin, asiwo kushandiswa kweboka repolar rine epoxy resin kurapa maitiro.Uku kusanganiswa kwehunhu, kuwana yakakwana yekubatanidza kusimba pakati pehutatu hwekupotera, nepo zvimiro uye hunhu hwematanho akateerana kuita matatu-layer coating kuti ienderane.Iyo inoratidzirwa nemutengo wakakwira uye yakaoma nzira.
