Umahluko phakathi kwe-HDPE kunye ne-PE

I-HDPE ikwabizwa ngokuba yi-high density polyethylene material.Luhlobo lweresin ye-thermoplastic ene-crystallinity ephezulu kunye ne-non polarity.Ukubonakala kwe-HDPE yoqobo imhlophe emhlophe kwaye iguquguquke kwinqanaba elithile kwicandelo elincinci.Ipolymer ayinayo i-hygroscopic kwaye inokumelana kakuhle nomphunga wamanzi, ongasetyenziselwa iinjongo zokupakisha.I-HDPE ineempawu ezilungileyo zombane, ngakumbi amandla aphezulu e-dielectric of insulation, okwenza ukuba ifaneleke kakhulu iingcingo kunye neentambo.Phakathi ukuya kwibakala eliphezulu lemolekyuli inempembelelo ebalaseleyo yokumelana nobushushu begumbi okanye nokuba -40f ubushushu obuphantsi.I-HDPE isoloko isetyenziswa njengeukufaka umbhobho, kunye nabanyeizinto zokudlala, iplagi yePK , iaudio.

Ngenxa yamandla ahlukeneyo, iipayipi ze-HDPE kufuneka zithwale uxinzelelo oluthile.Ngokuqhelekileyo, ii-resin ze-PE ezinobunzima obukhulu be-molecular kunye neempawu ezintle zemishini, ezifana ne-HDPE resins, kufuneka zikhethwe.Amandla ngamaxesha angama-9 kumbhobho we-polyethylene eqhelekileyo (ipayipi ye-PE).

Ukumelana nokunxiba kuyahluka.Kuzo zonke iiplastiki zobunjineli, i-HDPE ineyona nto ixhaphakileyo yokunxiba.Ukuphakama kwe-molecular weight, i-peaty-resistant-resistant material, kunye nangaphezulu kwezixhobo ezininzi zetsimbi (ezifana ne-carbon steel, i-stainless steel, i-bronze, njl.), i-PE eqhelekileyo sisinye seshumi kuphela se-HDPE.

Imibhobho ye-HDPE ineempembelelo ezahlukeneyo zokutshintsha.Ziyimveliso yokutshintshwa kwemibhobho yentsimbi yemveli kunye nemibhobho yamanzi okusela i-polychloroprene.Nangona kunjalo, i-PE polychloroprene ingasetyenziselwa kuphela umbhobho wesiteshi sangaphandle, kwaye kunye nemibhobho ye-PE ephantsi ingasetyenziselwa kuphela amanzi.

Umda wesicelo wahlukile.Imibhobho ye-HDPEzisetyenziselwa ikakhulu: inkqubo yonikezelo lwamanzi yobunjineli bakamasipala, inkqubo yonikezelo lwamanzi angaphakathi kwezakhiwo, inkqubo yonikezelo lwamanzi engcwatyiweyo yangaphandle kunye nenkqubo yonikezelo lwamanzi engcwatyiweyo yeendawo zokuhlala kunye neendawo zeplanti, ukulungiswa kwemibhobho emidala, inkqubo yemibhobho yobunjineli yokucoca amanzi, imibhobho yamanzi kwimizi-mveliso igadi, ukunkcenkceshela kunye namanye amasimi.Imibhobho ye-PE yoxinano oluphakathi ilungele kuphela ukuthutha igesi eyenziwe ngegesi, irhasi yendalo kunye nerhasi yepetroleum engamanzi.Imibhobho ye-PE yoxinaniso oluphantsi yimibhobho.
