Polyethylene njupụta dị elu (HDPE): Njirimara ihe na ngwa
Polyethylene dị elu (HDPE) bụ polymer thermoplastic nke a na-ejikarị eme ihe nke ụlọ ọrụ dị iche iche kwadoro maka njirimara anụ ahụ dị mma na nkwụsi ike kemịkal. N'isiokwu a, anyị ga-enyocha ihe onwunwe nke HDPE, usoro mmepụta ya na ngwa ngwa ya dị iche iche iji nyere aka ịghọta nke ọma ihe a dị mkpa.
I. Nkọwa na njirimara nhazi nke HDPE
Polyethylene dị elu (HDPE) bụ polymer linear mepụtara site na mgbakwunye polymerisation nke ethylene monomer. Ọ nwere ogo dị elu nke crystallinity na njupụta dị elu (n'elu 0.940 g / cm³), nke metụtara ọnụ ọgụgụ dị ala nke eriri alaka na usoro ihe omimi ya. Nhazi nso nke eriri molecular nke HDPE na-enye ya ike na-arụ ọrụ nke ọma na ike siri ike, ebe ọ na-ejigide mgbanwe dị mma na ductility.
II. Njirimara anụ ahụ na kemịkalụ nke HDPE
HDPE nwere akụrụngwa anụ ahụ na kemịkalụ pụrụ iche na-eme ka ọ bụrụ asọmpi dị ukwuu na ngwa ụlọ ọrụ mmepụta ihe:

Nguzogide kemịkalụ: HDPE nwere nkwụsi ike dị elu n'okpuru ọrụ nke ọtụtụ kemịkalụ, acid, alkalis na ihe mgbaze organic, yabụ dabara adaba maka nchekwa na ibufe mmiri mmiri na-emebi emebi.
Ike dị elu na nguzogide mmetụta: Ibu arọ ya dị elu na-enye HDPE ike ike dị mma na nguzogide mmetụta, ya mere a na-ejikarị eme ọkpọkọ, akpa na ihe nkwakọ ngwaahịa.
Mmiri dị ala na mkpuchi dị mma: HDPE nwere oke mmiri dị ala na ihe mkpuchi ọkụ eletrik dị mma, na-eme ka ọ dị mma maka ịkwanye eriri na mkpuchi.
Okpomọkụ na-eguzogide: ọ nwere ike ịnọgide na-enwe nkwụsi ike nke anụ ahụ Njirimara na okpomọkụ nso nke -40 ℃ ka 80 ℃.

Nke atọ, usoro mmepụta nke polyethylene dị elu
A na-emepụta HDPE site na ụzọ atọ polymerisation: usoro nke gas, usoro ngwọta na usoro nkwusioru. Ọdịiche dị n'etiti ụzọ ndị a dabere na ọdịiche dị n'etiti usoro mmeghachi omume na ọnọdụ ọrụ:

Usoro nke gas: site na polymerising ethylene gas ozugbo n'okpuru ọrụ nke onye na-emepụta ihe, usoro a dị ọnụ ala na arụmọrụ dị elu, ma ugbu a bụ usoro a na-ejikarị eme ihe.
Usoro ngwọta: ethylene na-agbaze na ihe mgbaze na polymerised n'okpuru nrụgide dị elu na ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-emepụta ihe dị elu ma dị mma maka nkwadebe nke HDPE dị elu.
Usoro nkwusioru: A na-eme polymerisation site na ịkwụsịtụ ethylene monomer na mmiri mmiri mmiri, usoro a nwere ike ịchịkwa ọnọdụ polymerisation nke ọma ma dabara maka mmepụta HDPE dị elu.

IV. Ebe isi ngwa nke HDPE
N'ihi arụmọrụ ya dị mma, a na-eji HDPE eme ihe n'ọtụtụ ụlọ ọrụ:

Ihe nkwakọ ngwaahịa: A na-ejikarị HDPE na-emepụta ihe nkwakọ ngwaahịa dị ka karama, drum, arịa na ihe nkiri, karịsịa ihe nri nri n'ihi na ọ naghị egbu egbu, enweghị isi na ihe na-eguzogide corrosion.
Ihe owuwu na akụrụngwa: A na-eji HDPE na-emepụta pipework (dịka ọmụmaatụ mmiri na ọkpọkọ gas), ebe nguzogide corrosion ya, nguzogide UV na ịdị mfe nke nrụnye emeela ka ọ bụrụ onye a ma ama na ụlọ ọrụ ihe owuwu.
Ụlọ ọrụ USB: Ihe mkpuchi ọkụ eletrik HDPE na-eme ka ọ dị mma maka iji ya mee ihe maka mkpuchi eriri na mkpuchi.
Ngwaahịa ndị ahịa: A na-ejikwa HDPE n'ọtụtụ ebe n'ichepụta ngwa ahịa ndị ahịa kwa ụbọchị dịka akpa rọba, ihe egwuregwu ụmụaka, arịa ụlọ na arịa ụlọ.

V. Ihe ịma aka gburugburu ebe obibi na mmepe nke HDPE n'ọdịnihu
N'agbanyeghị ngwa ngwa ya dị iche iche, ọdịdị HDPE na-abụghị nke biodegradable na-ebute ihe ịma aka gburugburu ebe obibi. Iji belata mmetụta nke mkpofu rọba na gburugburu ebe obibi, ọtụtụ ụlọ ọrụ amalitela ịmụ banyere imegharị na iji teknụzụ HDPE. Ka ọ dị ugbu a, ọtụtụ mba na mpaghara ewepụtala sistemu eji emegharị ihe iji megharịa ihe HDPE eji eme ihe n'ime ngwaahịa ọhụrụ iji kwalite iji akụrụngwa na-adigide.
N'ọdịnihu, mmepụta na ngwa nke HDPE na-adịgide adịgide ga-abụ nyocha ọhụụ ọhụrụ ka mmata gburugburu ebe obibi na-abawanye na ọganihu teknụzụ. Usoro gụnyere mmepe nke HDPE dabeere na bio na usoro imegharị ihe ka mma ga-enyere aka belata mmetụta gburugburu ebe obibi na-adịghị mma nke ihe a ma na-ejigide ọnọdụ ya dị mkpa n'ahịa.
