Polyethylene e fetotsoeng ke eng?
Mefuta e fetotsoeng ea polyethylene haholo-holo e kenyelletsa polyethylene e chlorinated, chlorosulfonated polyethylene, polyethylene e kopantsoeng le mefuta e fapaneng e fetotsoeng.
Polyethylene ea K'hemik'hale:
Kloride e sa reroang e fumanoeng ka ho khutlisetsa liathomo tsa haedrojene sebakeng sa polyethylene ka chlorine. Chlorination e etsoa tlas'a ho qalisoa ha leseli kapa peroxide, 'me e hlahisoa haholo-holo ke mokhoa oa ho emisa metsi ka har'a indasteri. Ka lebaka la phapang ea boima ba limolek'hule le kabo, degree ea branching, degree ea chlorination kamora chlorination, kabo ea athomo ea chlorine le masala a crystallinity a polyethylene e tala, polyethylene ea chlorinated ho tloha rabara ho ea ho polasetiki e thata e ka fumanoa. Tšebeliso e ka sehloohong ke e le mofetoleli oa polyvinyl chloride ho ntlafatsa ho hanyetsa ha polyvinyl chloride. Polyethylene ea chlorinated ka boeona e ka boela ea sebelisoa e le lisebelisoa tsa motlakase le lisebelisoa tsa fatše.
Chlorosulfonated polyethylene:
Ha polyethylene e arabela ka chlorine e nang le sulfur dioxide, karolo ea liathomo tsa hydrogen ka molek'hule e nkeloa sebaka ke chlorine le lihlopha tse nyenyane tsa sulfonyl chloride ho fumana chlorosulfonated polyethylene. Mokhoa o ka sehloohong oa indasteri ke mokhoa oa ho emisa. Chlorosulfonated polyethylene e hanyetsana le ozone, ho bola ha lik'hemik'hale, oli, mocheso, leseli, abrasion le matla a tsitsitseng. Ke elastomer e nang le thepa e ntle e felletseng mme e ka sebelisoa ho etsa likarolo tsa lisebelisoa tse amanang le lijo.
XLPE:
Ho sebelisa mokhoa oa mahlaseli (X-ray, electron beam kapa ultraviolet irradiation, joalo-joalo) kapa mokhoa oa lik'hemik'hale (peroxide kapa silicone cross-linking) ho etsa polyethylene e nang le linear hore e be marang-rang kapa polyethylene e ngata e amanang le sefapano. Har'a tsona, mokhoa oa ho kopanya li-silicone o na le mokhoa o bonolo, litšenyehelo tse tlaase tsa ts'ebetso, 'me ho bōptjoa le ho kopanya ho ka etsoa ka mehato, kahoo ho phunya le ho bōptjoa ha ente ho loketse. Ho hanyetsa mocheso, khatello ea khatello ea tikoloho le thepa ea mechine ea polyethylene e kopantsoeng le sefapano e ntlafetse haholo ha e bapisoa le polyethylene, 'me e loketse liphaephe tse kholo, lithapo le lithapo le lihlahisoa tsa rotomolding.
Ho fetola motsoako oa polyethylene:
Kamora ho kopanya li-linear low density polyethylene le polyethylene e tlase, e ka sebelisoa ho sebetsana le lifilimi le lihlahisoa tse ling, mme ts'ebetso ea sehlahisoa e betere ho feta polyethylene e tlase. Rabara ea polyethylene le ethylene propylene e ka kopanngoa ho hlahisa mefuta e mengata e fapaneng. thermoplastic lisebelisoa tsa elastomer
