Polyethylene (PE) bụ resin thermoplastic mere site na polymerization nke ethylene.Na ụlọ ọrụ mmepụta ihe, ọ gụnyekwara ethylene na obere ego nke α-Copolymers nke olefins.Polyethylene enweghị isi, anaghị egbu egbu, ọ dịkwa ka wax.Ọ nwere ezigbo nguzogide okpomọkụ dị ala (opekempe ọrụ okpomọkụ nwere ike iru - 100 ~ - 70 Celsius C), nkwụsi ike kemịkalụ dị mma, ma nwee ike iguzogide ọtụtụ ọgụ acid na alkali (anaghị eguzogide acids na akụrụngwa oxidizing).Ọ bụ ihe na-adịghị ahụkebe n'ozuzu ihe mgbaze na okpomọkụ nkịtị, na obere mmịnye mmiri na mkpuchi ọkụ eletrik mara mma.
Ọnụego ojiji nke ikike mmepụta polyethylene dị na China dị elu, a na-echekwa ya na ihe dịka 90% n'afọ niile.Site na mmepe nke akụ na ụba China, ọchịchọ nke ahịa polyethylene na-abawanye ngwa ngwa, mmepụta na-abawanye.N'afọ ndị na-adịbeghị anya, ikike mmepụta na mmepụta polyethylene nke China nọgidere na-arịwanye elu.Ihe nrụpụta polyethylene nke China bụ ihe dị ka nde tọn 22.72, yana mmụba kwa afọ nke 11.8%, na mmepụta ga-agafe nde tọn 30.
Oriri polyethylene pụtara nke nta nke nta mụbara.N'afọ 2021, ọnụ ahịa polyethylene pụtara na China gbadara ruo nde tọn 37.365, mbelata kwa afọ nke 3.2%.Ọ bụ n'ihi mmetụta nke ọnọdụ ọrịa na njikwa ike oriri, na ụfọdụ ụlọ ọrụ ndị dị n'okpuru ala na-akwụsịlata ma ọ bụ belata mmepụta mmepụta.Site na nkwalite nke izu oke nke onwe, ịdabere na mbubata PE ga-eji nwayọọ nwayọọ belata.N'ọdịnihu, na mmụba nke ọnọdụ ọrịa na-arịwanye elu na ụba nke akụ na ụba ụlọ, ọchịchọ PE ga-anọgide na-abawanye.A na-atụ anya na ọ ga-eji nwayọọ nwayọọ gbakee na 2022, na-abawanye ruo nde tọn 39.
