Lithekiso tsa moetsi oa lipeipi tsa metsi a polyethylene
Inner epoxy outer polyethylene anticorrosive steel pipe ke mofuta o mocha oa phala ea tšepe e kopantsoeng ea polasetiki. E entsoe ka substrate ea tšepe ea tšepe, epoxy resin e ka hare le seaparo sa ka ntle sa polyethylene. E na le thepa e babatsehang ea mechine, ho hanyetsa kutu le ho hanyetsa botsofali. E sebelisoa haholo ho boloka metsi, matla a motlakase, indasteri ea lik'hemik'hale, peterole le liindasteri tse ling tse ngata.
Pipe ea tšepe e ka hare ea epoxide e ka ntle ea polyethylene e thibelang ho bola e arotsoe ka: fusion ea ka hare e kopantsoeng le phofo e ka ntle ea polyethylene anticorrosive steel pipe, epoxy phofo e ka hare ea polyethylene anticorrosive steel pipe, fusion e ka hare e kopantsoeng le phofo ea epoxy ka ntle ea polyethyle e ka ntle. 3PE) phala ea tšepe e thibelang ho bola, mokelikeli o ka hare oa epoxy (ipn8710) phala ea tšepe e nang le likarolo tse tharo tsa polyethylene e thibelang ho bola.
Sebopeho sa sebopeho sa epoxide e ka hare le polyethylene ea ka ntle ea monolayer
1. Lisebelisoa tsa motheo tsa lipeipi tsa tšepe: phala ea tšepe e se nang moeli, phala ea tšepe e entsoeng ka motlakase (weld e otlolohileng, spiral weld)
2. Ho roala ka hare ho thibela ho bola: fusion ea sanitary bonded epoxy powder coating, heavy-duty anti-corrosion fusion bonded epoxy resin powder.

3. Ho roala ka ntle ho anti-corrosion: ho chesa ho qhibiliha ha polyethylene phofo e le 'ngoe
Sebopeho sa ka hare sa epoxide se nang le likarolo tse tharo tsa polyethylene (3PE).
1. Lisebelisoa tsa motheo tsa lipeipi tsa tšepe: phala ea tšepe e se nang moeli, phala ea tšepe e entsoeng ka motlakase (weld e otlolohileng, spiral weld)
2. Ho roala ka hare ho thibela ho bola: fusion ea sanitary bonded epoxy powder coating, heavy-duty anti-corrosion fusion bonded epoxy resin powder.
3.Sekoaelo sa ka ntle se khahlanong le kutu: ho qhibiliha ho chesang ha polyethylene e nang le likarolo tse tharo. Karolo e ka tlase ke phofo e kopantsoeng ea epoxy resin powder, karolo e bohareng ke sekhomaretsi se chesang se qhibilihisang, 'me karolo e ka ntle ke polyethylene e phahameng haholo.
Papiso pakeng tsa ka hare epoxide kantle monolayer PE le ka hare epoxide kantle 3PE
Polyethylene le epoxy li na le khanyetso e ntle ea kutu, empa e 'ngoe le e' ngoe e na le melemo ea eona. Polyethylene ke thepa ea thermoplastic e nang le maemo a bonolo le a hanyetsanang le bump. Ka lebaka la limolek'hule tse se nang polar, ho phehella ha ho khomarela pakeng tsa polyethylene le pipe ea tšepe ho futsanehile; Epoxy resin ke molek'hule ea polar e nang le lihlopha tsa hydroxyl. Ka mocheso o itseng, ho bonolo ho itšoara ka liphaephe tsa tšepe 'me ho na le ho khomarela ka matla. Leha ho le joalo, ha e hanane le ho thulana hobane ke ntho ea thermosetting. Ka hona, motsoako oa lisebelisoa tse peli ke tsa motsoako o motle ka ho fetisisa indastering ea anti-corrosion.
Indasteri ea liphaephe tsa tšepe e entsoeng ka polasetiki e entsoeng ka polasetiki e ile ea ntlafatsoa ho tloha polyethylene ea pele le ea ka ntle ho epoxy e ka hare le e ka ntle ka lebaka la mathata a ho khomarela, empa lesela la epoxy le ka ntle ha le hanyetsane le ho thulana. Hamorao, e ile ea tsoela pele ho ea molokong oa boraro ka hare ho polyethylene e ka ntle ea epoxy, empa bothata ba ho khomarela bo ntse bo le teng ha polyethylene e le 'ngoe e kopantsoe ka ho toba le phala ea tšepe. Qetellong, e ile ea ntlafatsoa ho ea molokong oa bone oa anti-corrosion internal epoxy outside three-layer structural polyethylene.
