Polyethylene bụ ebe a na-emegharị polymerization nke ethymene, bụ otu n'ime ihe ndị a na-ahụkarị Plastics na ngwaahịa , nrụpụta kwa afọ nke 100 nde tọn polyethylene resin, na-ebute 34% nke ahịa plastik. Ngwaahịa na ngwaahịa ndị ọzọ a na-ahụkarị (polyethylene tere) .pvc (polyvinych chloride) .pp (polypropylene) .PPslenene) na ndị ọzọ.

Polymer kristal na-ahụkarị, na-agbaze na 130 ℃ ~ 145 ℃, nke a na-ahụkarị, na-abụghị ihe na-egbu egbu, na-enweghị ihe na-egbu egbu, na-adịghị egbuntụ, na-adịghị egbu egbu, na-acha ọcha.

High Pressure Polyethylene

Polyethylene dị elu (ldpe), aha zuru oke nke polyethylene dị ala, nke a na-akpọkarị "ụlọ ọrụ dị elu" na ụlọ ọrụ; Polyethylene dị ala (HDPE), aha zuru oke na-enwekarị ike nrụgide polyethylene, zoro aka na "obere nrụgide".

Ọdịiche dị n'etiti polyethylene dị elu na obere ọrịa polyethylene dị ala: tumadi site na mmepụta ma jiri ịmata ọdịiche dị iche iche:
Nnukwu mgbali elu: Iji ọkwa ọkwa polymerization dị ka akụrụngwa, oxygen (ma ọ bụ ikuku na-emegharị anya, na-eji 130 ísì ụtọ Celmalis dị elu maka polymerization iji mee.

Nrụgide dị ala: Ethylene dị elu dị ka akụrụngwa, proplene ma ọ bụ 1-Beene dị ka onye na-eme ihe dị elu, na-eji ụfọdụ okpomọkụ (65-8-0.7MPA) ihe ngwọta A na-eme nke polymerization, na-esochi ya, ihicha, na-egbu egbu, na granilation.

Na:
Ihe nkiri polyethylene dị elu: kwesịrị ekwesị maka usoro nhazi, ihe nkiri, mkpokọta ihe nkiri, mkpokọta, nchebe, nchebe na USB Setịpụrụ, akpa, kemịkal, akwụkwọ sịntetik, ngwaahịa ngwaahịa ndị agha, wdg.

Polyethylene dị ala: tumadi eji ihe ọ bụla na-akpụ akpụ, na-emepụta ihe dị iche iche, a na-emepụta ihe dị iche iche, ihe nkiri, akpa mara mma waya, Monofules, wdg.

Low Pressure Polyethylene

Isi akwụkwọ:
A na-ejikarị LDPE na ngwa, yana ezigbo nghọta na ezigbo nhazi Njirimara, mana Njirimara nke ndị na-arụ ọrụ adịghị mma.

Enwere ọtụtụ ngwa maka HDPE: nke ahụ bụ eriri akpa (ihe dị iche iche a na-eme (ya bụ, ihe nkiri), na-akpụ akpụ, dị ka karama ndị pere mpe.
