Okwu mmalite nke mkpuchi ntụ ntụ LDPE
Mkpuchi ntụ ntụ LDPE bụ ụdị mkpuchi e ji resin polyethylene dị ala (LDPE) mee. A na-ejikarị ụdị mkpuchi a eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere ngwa, ụgbọ ala, ụgbọelu, na ihe owuwu.
Mkpuchi ntụ ntụ bụ usoro e ji etinye ntụ ntụ kpọrọ nkụ n'elu ala site na iji chaja electrostatic ma ọ bụ akwa fluidized . A na-ekpocha ntụ ntụ ahụ ruo n'okpomọkụ dị elu, na-eme ka ọ gbazee ma mepụta mkpuchi dị nro, nke dabara adaba. Mkpuchi ntụ ntụ LDPE bụ ụdị usoro a nke na-eji resin LDPE eme ihe dị ka ihe mkpuchi.
Mkpuchi ntụ ntụ LDPE bụ mkpuchi ntụ ntụ thermoplastic kachasị ukwuu ma a na-ejikarị eme ihe . Resin dị mma na-enye ntọala maka mkpuchi na-egbuke egbuke.

Ihe mkpuchi ahụ nwere uru ndị a:
- ezigbo mmiri na-eguzogide, acid na alkali resistance, chemical resistance, and water absorption rate under 0.001%;
- ezigbo mkpuchi ọkụ na mkpuchi ọkụ eletrik, enweghị mmebi eletrik;
- ike tensile magburu onwe ya, mgbanwe, na nguzogide mmetụta;
- ezigbo nguzogide okpomọkụ dị ala, enweghị mgbawa na -40 ℃ maka ihe karịrị awa 400, kwesịrị ekwesị maka ojiji na gburugburu oyi na ugwu;
- ọnụ ala akụrụngwa na-adịghị egbu egbu.
Ụdị mkpuchi ntụ ntụ a na-enye mkpuchi ahụ ọkwa dị mma, ịdị nro, na mmetụta dị ka wax. Mgbe mkpuchi nke mkpuchi ntụ ntụ thermoplastic dị ala batara na kọntaktị ụfọdụ ihe mgbaze ma ọ bụ ihe nchacha, ọ ga-agbaji ngwa ngwa n'ihi mgbawa nrụgide.
Ọtụtụ mgbe, a na-eji resins ndị ọzọ na-agbanwe resin polyethylene iji meziwanye ihe arụ ọrụ nke mkpuchi ntụ ntụ polyethylene, meziwanye nrapado ya na mkpụrụ, ma kwalite mmepe nke ụdị mkpuchi a, na-agbasawanye mpaghara ngwa ya.
Thermoplastic LDPE ntụ ntụ mkpuchi nwere ike tinye site fluidized bed immersion mkpuchi ma ọ bụ electrostatic ntụ ntụ mkpuchi, n'ozuzu na-eji mbụ.
Otú ọ dị, ụdị mkpuchi ntụ ntụ a nwekwara ụfọdụ adịghị ike, kpọmkwem na:
