Arụmọrụ: okpomọkụ arụ ọrụ: -25 degrees ~ + 75 ogo (okpomọkụ kachasị arụ ọrụ nke polyethylene gbanwetụrụ: 105 degrees)
Nrụgide arụ ọrụ nke etiti: nrụgide dị mma bụ 2.5MPa na nrụgide na-adịghị mma bụ 75 KPa
Nguzogide corrosion: acid nonoxidation (dị ka hydrochloric acid, hydrochloric acid, itule sulfuric acid, hydrofluoric acid), itughari nitric acid, alkali na nnu ngwọta, ma ọ dịghị eguzogide corrosion nke lekwasịrị nitric acid, lekwasị sulfuric acid na ndị ọzọ siri ike oxidants. Ezi corrosion iguzogide organic solvents na na nkịtị okpomọkụ.
Ngwa a na-ahụkarị: adabara ụgbọ njem mmiri na-emebi emebi n'ozuzu, nke dabara adaba maka njem nke mmiri ụlọ na ị drinkụ mmiri oyi na mmiri oyi, nnyefe mmiri, anaghị emetụta ogo mmiri, n'usoro ihe achọrọ maka ịdị ọcha nri, akwa mkpuchi mkpuchi elu njupụta polyethylene pipe nwere ike iji ya mee njem nke mmiri siri ike slurry dị ka coal, ore. A na-eji ya na ngwaahịa petrochemical mmiri eletriki nchekwa gburugburu ebe obibi na ụlọ ọrụ ndị ọzọ.
⑴ Njikọ a pụrụ ịdabere na ya: a na-ejikọta usoro ọkpọkọ polyethylene site na ọnọdụ mgbaze ọkụ eletrik, na ike nke nkwonkwo dị elu karịa nke ọkpọkọ ahụ.
⑵ Ọdịmma dị ala{0}} nguzogide mmetụta okpomọkụ: obere - okpomọkụ embrittlement okpomọkụ nke polyethylene dị obere, nke enwere ike iji ya n'enweghị nsogbu na oke okpomọkụ nke-60-60 degrees. N'ime ụlọ oyi, n'ihi mmetụta dị mma na-eguzogide ihe, ọkpọkọ ọkpọkọ ọkpọ agaghị eme.
⑶ Ezigbo nguzogide mgbawa mgbawa: HDPE nwere mmetụta uche dị ala, ike ịkwa akwa na nkwụsi ike dị mma, nguzogide nrụgide gburugburu ebe obibi bụkwa ihe pụtara ìhè.
⑷ Ezigbo nguzogide corrosion kemịkalụ: pipeline HDPE nwere ike na-eguzogide corrosion nke ọtụtụ mgbasa ozi kemịkalụ, na kemịkalụ dị na ala agaghị eme ka ọ bụrụ mmebi nke pipeline. Polyethylene bụ ihe mkpuchi eletriki, nke na-adịghị ire ere, nchara ma ọ bụ corrosion electrochemical; ọ naghị akwalite uto nke algae, nje bacteria ma ọ bụ fungi.
⑸ Nguzogide ịka nká, ogologo ndụ ọrụ: ọkpọkọ polyethylene nwere 2-2.5% nke nkesa edo edo nke carbon ojii nwere ike ịchekwa na ikuku dị n'èzí ma ọ bụ jiri ya mee ihe ruo afọ 50, na-enweghị mmebi n'ihi radieshon ultraviolet.
⑹ Ezigbo nguzogide na-eyi: nnwale nleba anya nleba anya nke ọkpọkọ HDPE na ọkpọkọ ígwè na-egosi na nguzogide iyi nke ọkpọkọ HDPE bụ ugboro 4 nke ọkpọkọ ígwè. N'ihe gbasara njem apịtị, ọkpọkọ HDPE nwere nguzogide ka mma ma e jiri ya tụnyere ọkpọkọ ígwè, nke pụtara na ọkpọkọ HDPE nwere ogologo ndụ ọrụ na akụnụba ka mma.
⑺ Mgbanwe dị mma: mgbanwe nke ọkpọkọ HDPE na-eme ka ọ dị mfe na-ehulata, injinia nwere ike ịgbanwe ntụziaka nke pipeline gburugburu ihe mgbochi, n'ọtụtụ ọnọdụ, mgbanwe nke pipeline nwere ike ibelata ọnụ ọgụgụ nke ọkpọkọ ọkpọkọ ma belata ọnụahịa ntinye.
⑻ Obere nguzogide na-asọ asọ: HDPE ọkpọkọ nwere elu dị mma n'ime, yana ọnụọgụ Manning bụ 0.009. Arụmọrụ dị nro na njirimara enweghị{1} adhesion na-ahụ na pipeline HDPE nwere ikike mbufe dị elu karịa ọkpọkọ ọdịnala, mana ọ na-ebelata mfu nrụgide na ike nnyefe mmiri.
⑼ Mfe njikwa: HDPE ọkpọkọ dị ọkụ karịa ọkpọkọ kọn, galvanized ọkpọkọ na ọkpọkọ ígwè, ọ dị mfe iburu na ịwụnye, obere ikike na akụrụngwa chọrọ, nke pụtara na ntinye ego nke ọrụ ahụ na-ebelata nke ukwuu.
⑽ A dịgasị iche iche nke ọhụrụ ewu ụzọ: HDPE pipeline nwere a dịgasị iche iche nke na-ewu technology, na mgbakwunye na nwere ike iji omenala ụzọ nke igwu gwuputa ewu, nwekwara ike iji a dịgasị iche iche nke ọhụrụ trenchless technology dị ka ọkpọkọ jacking, directional mkpọpu ala, lining, crack tube ewu, nke a maka ụfọdụ adịghị ekwe ka gwuputa, bụ nanị nhọrọ, otú HDPE pipeline ngwa n'ọtụtụ ebe.
1, nro: n'ihi na PE -RT dị nro. Ya mere, ọ dịghị ngwá ọrụ pụrụ iche a chọrọ n'oge a na-ewu ụlọ, ya mere ọnụ ahịa ihe owuwu ahụ dị ntakịrị . 2, okpomọkụ conductivity: ọkpọkọ eji eme ihe maka ikpo ọkụ n'ala kwesịrị inwe ezigbo okpomọkụ. PE-RT nwere ezigbo thermal conductivity, na thermal conductivity ji okpukpu abụọ karịa nke ọkpọkọ PP-R na PP-B. Zuru oke maka kpo oku ala.3. Nguzogide okpomọkụ dị elu: PE{10}RT nwere ike iguzogide okpomọkụ dị elu ruo ogo 90, ebe PEX nwere ike iru 65 degrees .4, obere - okpomọkụ na-eguzogide okpomọkụ na nguzogide mmetụta: PE{15}}RT obere{16}} ịrụ ọrụ nguzogide okpomọkụ dị mma. N'oge oyi na-ewu ụlọ, ọkpọkọ adịghị mfe emetụta ma gbajie, nke na-eme ka mgbanwe nke nhazi ihe owuwu dị.5, nchedo gburugburu ebe obibi: PE{19}RT na PP{20}R nwere ike ịmegharị ya, na-enweghị imetọ gburugburu ebe obibi. Enweghị ike ịmegharị PEX
Ihe nchịkọta dị ọkụ: China pe linear plastic ọkpọkọ na-emepụta, ndị na-ebu, ụlọ ọrụ
