A na-eji akwa polyethylene eme ihe n'ọtụtụ ọrụ injinia

Efere polyethylene nke a bụ n'ihi na ụdọ molekụla mgbe ụfọdụ na-egbochi fotocrystal ha, na-ahapụ nnukwu mpaghara amorphous na biomolecule, efere polyethylene nwere ike itinye mmetụta dị ukwuu na ike kinetic.Dị ka akwụkwọ ntụaka si kwuo, a na-eji usoro asm-D256 iji chọpụta mmetụta nke uru ike mkpakọ rọba.Dị ka ntụnyere, ike compressive osisi polyethylene nwere ike kewaa na polycarbonate, polycarbonate mara maka mmetụta ya na-eguzogide, na ike ga-eji dị ka n'ozuzu roba ngwaahịa.

Nguzogide esemokwu nke efere polyethylene dị obere.Mbadamba polyethylene nwere nguzogide iyi ka mma, nguzogide esemokwu dị ala yana ezigbo mmiri mmiri.Ọ bụ nrọ akụrụngwa nke ịhịa aka n'ahụ, ihe na-akpụ akpụ na ahịhịa.Nhọrọ nke polyethylene osisi dị ka esemokwu ụzọ, ọ bụghị naanị nwere ike melite mebiri emebi ndụ ọrụ nke akụrụngwa, polyethylene osisi na ike ịzọpụta ihe onwunwe.

Osisi polyethylene nwere ezigbo nguzogide kemịkalụ.Osisi polyethylene nwere nguzogide kemịkalụ ka mma.Na mgbakwunye na nitric acid na sulfuric acid gbanyere mkpọrọgwụ, osisi polyethylene adịghị mfe ịtinye na ngwọta alkaline ọ bụla ma ọ bụ acidic.Enwere ike iji ya dị ka dilute hydrochloric acid na 80 ℃, na sodium cyanide & LT;Hydrochloric acid & lt;75% dị nro, nwekwara ike iji mmiri na mmiri ihicha.Dị ka onye ọ bụla maara, polyethylene osisi dị mfe na-aza na aliphatic hydrocarbons ma ọ bụ halogenates (karịsịa na-aga n'ihu elu okpomọkụ), n'ihi ya, e kwesịrị ilebara anya na-eji ya.

Melite nguzogide eyi nke osisi polyethylene.Akwa mkpuchi mkpuchi bụ otu n'ime njirimara na-adọrọ adọrọ, osisi polyethylene n'ọtụtụ ọrụ na iji isi ihe eji eme ihe.N'oge a, ihe niile plastic polyethylene osisi nwere ezigbo ihe mgbochi na-eyi, na ọbụna ọtụtụ ihe ígwè anaghị adị ka ọ dị na mbụ.Site na mmụba nke ịdị arọ molecular nke polyethylene nrụgide dị elu, a na-emeziwanye ihe mgbochi nke ụdị ihe a.Mmetụta mmetụta nke osisi polyethylene.Ike mkpakọ nke efere polyethylene jikọtara ya na ịdị arọ ya.Mgbe ịdị arọ molekụla dị n'ihe dị ala karịa nde abụọ, mmetụta mkpakọ ike nke efere polyethylene na-abawanye na mmụba nke ịdị arọ molekụla, ọnụ ahịa dị elu dị ihe dị ka nde abụọ.N'oge a, mmetụta mkpakọ ike ga-ebelata na mmụba nke ikwu arọ molekụla.
