Ọkwa njupụta Polyethylene Injection Molding Ọkwa
HDPE bụ resin thermoplastic nke na-abụghị polar nke kristal emepụtara site na copolymerization nke ethylene na obere ego nke monomer α-olefin.A na-emepụta HDPE n'okpuru nrụgide dị ala, ya mere a na-akpọkwa ya polyethylene dị ala.HDPE bụ usoro ihe omimi nke ahịrị ma nwee obere alaka.Ọ nwere ọkwa dị elu nke crystallization na njupụta dị elu.Ọ nwere ike iguzogide okpomọkụ dị elu ma nwee ezigbo nkwụsi ike na ike ọrụ na mgbochi kemịkalụ.
HDPE injection ịkpụzi ọkwa nwere ezi itule nke rigidity na siri ike, ezigbo mmetụta nguzogide na magburu onwe nke ala okpomọkụ iguzogide na ezi gburugburu ebe obibi mgbawa resistanse.Resin nwere ezigbo nkwụsi ike na nguzogide abrasion, yana ezigbo nhazi.
Ekwesịrị ịchekwa resin n'ụlọ nkwakọba ihe kpọrọ nkụ na ebe ọkụ na ìhè anyanwụ.E kwesịghị ikpokọta ya na mbara ikuku.N'oge njem, ihe ahụ ekwesịghị ikpughe ìhè anyanwụ ma ọ bụ mmiri ozuzo siri ike ma ghara ibugharị ya na ájá, ala, metal scrap, coal ma ọ bụ iko.Amachibidoro ibufe ya na ihe na-egbu egbu, ihe na-emebi emebi na ire ọkụ.
