Amakuru - Ibiranga CHUANGRONG PE Sisitemu yo kuvoma

Guhinduka

Guhindura imiyoboro ya polyethylene ituma igoramye hejuru, munsi, no kuzenguruka inzitizi kimwe no kuzamuka no guhindura icyerekezo.Rimwe na rimwe, imiyoboro ihindagurika irashobora gukuraho ku buryo bugaragara ikoreshwa rya fitingi kandi bikagabanya cyane ibiciro byo kwishyiriraho.

Umuyoboro wa CHUANGRONG PE urashobora kugororwa kuri radiyo ntarengwa hagati ya 20 na 40 z'umurambararo wa diameter, ahanini biterwa na SDR y'umuyoboro runaka.

Imbonerahamwe : Ntarengwa biremewe bend radiyo ya HDPE umuyoboro kuri 23℃

Uburemere bworoshye

Icyizere cy'ubuzima

Ubucucike bwibikoresho bya PE ni 1/7 gusa cyibyuma. Uburemere bwumuyoboro wa PE ni muto cyane ugereranije nubwuma bwa beto, cyangwa umuyoboro wibyuma. Sisitemu yo kuvoma PE iroroshye kubyitwaramo no kuyishyiraho, kandi kugabanya imbaraga zabantu nibisabwa bishobora kuvamo kuzigama.

Igishushanyo mbonera cya hydrostatike cyumuyoboro wa CHUANGRONG gishingiye kumibare yagutse ya hydrostatike isuzumwa nuburyo busanzwe bwinganda.Imyitwarire yigihe kirekire yo guhangana ningutu yimbere itangwa na hydrostatike yingufu zishingiye kuri EN ISO 15494 (reba igice X). Imipaka yo gusaba imiyoboro n'ibikoresho, nkuko bigaragara ku gishushanyo cy'ubushyuhe-ubushyuhe, irashobora gukomoka kuri iyi mirongo, yerekana ko umuyoboro ufite igihe cyo kubaho kingana n'imyaka 50 iyo utwaye amazi kuri 20 ℃. Ibidukikije imbere n’imbere birashobora guhindura ubuzima buteganijwe cyangwa guhindura igishushanyo mbonera cyasabwe kubisabwa.

Ikirere

Ibyiza bya Thermal

Ikirere cya plastiki kibaho muburyo bwo kwangirika kwubutaka, cyangwa okiside, bitewe ningaruka ziterwa nimirasire ya ultra violet, ubushyuhe bwiyongereye, hamwe nubushuhe iyo imiyoboro ibitswe ahantu hagaragara. Umuyoboro wa polyethlence wirabura, urimo 2 kugeza 2,5% byigabanijwe neza byumukara wa karubone, urashobora kubikwa neza hanze yikirere hafi yimyaka myinshi nta byangiritse biturutse kuri ultra-violet. Umukara wa karubone nicyo kintu cyongeweho cyane kugirango uzamure ikirere cyibikoresho bya plastiki. Andi mabara nka cyera, ubururu, umuhondo cyangwa lilac ntabwo afite umutekano uhamye nka sisitemu yumukara pigmented kandi igihe cyo kumurika kigomba kugarukira kumwaka umwe kugirango ugumane neza imitungo. Hamwe na sisitemu yamabara yo hanze ya okiside yo hejuru itera imbere kuri umuvuduko wihuse kuruta uw'umukara wa karubone

imiyoboro ya PE itajegajega.Iyi miyoboro yamabara ntabwo isabwa hejuru yubutaka bukoreshwa.

Imiyoboro ya polyethylene irashobora gukoreshwa ku bushyuhe buri hagati ya 50 ° C na + 60 ° C. Ku bushyuhe bwo hejuru, imbaraga zingana no gukomera kwibikoresho biragabanuka Kubwibyo, nyamuneka saba igishushanyo mbonera cy'ubushyuhe. Kubushyuhe buri munsi ya O ° Cit bugomba kwemezwa ko uburyo budakonja, kugirango birinde kwangirika kwimiyoboro.

Kimwe na thermoplastique yose, PE yerekana kwaguka hejuru yubushyuhe bwicyuma. PE yacu ifite coefficent yumurongo wo kwagura ubushyuhe bwa 0.15 kugeza 0,20mm / m K, bikubye inshuro 1.5 kurenza urugero. PVC. Nkuko ibi byitaweho mugihe cyo gutegura igenamigambi ntihakagombye kubaho ibibazo muriki kibazo.

Ubushyuhe bwumuriro ni 0.38 W / m K.Kubera imitekerereze yavuyemo, sisitemu yo kuvoma PE ntabwo ifite ubukungu cyane ugereranije na sisitemu ikozwe mubintu nkumuringa.

Imyitwarire yo gutwikwa

Polyethylene ni iya plastiki yaka umuriro. Igipimo cya ogisijeni kingana na 17%. (Ibikoresho bitwika bitarenze 21% bya ogisijeni mu kirere bifatwa nk'ibicanwa).

PE itonyanga kandi ikomeza gutwika nta soot nyuma yo gukuraho urumuri. Ahanini, ibintu byuburozi birekurwa nuburyo bwose bwo gutwika. Umwuka wa karubone muri rusange ni ibicuruzwa byaka cyane ku bantu. Iyo PE yaka, cyane cyane dioxyde de carbone, monoxyde de carbone namazi ar.

Ubushyuhe bwo gutwika ni 350 ℃.

Ibikoresho bikwirakwiza umuriro ni amazi, ifuro, dioxyde de carbone cyangwa ifu.

Kurwanya Ibinyabuzima

Imiyoboro ya PE irashobora kwangizwa n’ibinyabuzima nkibimonyo cyangwa imbeba. Kurwanya ibitero bigenwa nubukomere bwa PE bwakoreshejwe, geometrie yimiterere ya PE, nuburyo bwo kwishyiriraho. Mu miyoboro ntoya ya diameter, ibice byurukuta ruto bishobora kwangizwa na terite mugihe gikabije. Nyamara ibyangiritse bikunze kwitwa igitero cyigihe gito muri PE byagaragaye ko biterwa nandi masoko yangiritse.

Sisitemu y'imiyoboro ya PE muri rusange ntabwo ibangamiwe n’ibinyabuzima by’ibinyabuzima haba ku butaka, ndetse no mu nyanja, kandi imiterere ya paraffinike y’imiyoboro ya PE ituma hubakwa imyenda yo mu nyanja muri serivisi.

Ibyiza by'amashanyarazi

$2Z {) QD7 [STC0E3_83Z4 $ 1P0$

Kubera amazi make ya PE, ibintu byamashanyarazi ntibibangamiwe no guhuza amazi adahoraho.Kubera ko PE ari polymer hydrocarbon polymer idafite polar, ni insulator idasanzwe.Iyi mitungo, ariko, irashobora kwangirika cyane biturutse kumwanda , ingaruka za okiside itangazamakuru cyangwa ikirere. Ijwi ryihariye rirwanya ni> 1017 Ωcm; imbaraga za dielectric ni 220 kV / mm.

Kubera iterambere rishoboka ryumuriro wa electrostic, urasabwa kwitonda mugihe ukoresheje PE mubisabwa aho ibyago byumuriro cyangwa guturika.

CHUANGRONGni uruganda rusangiwe nubucuruzi rwahujwe nubucuruzi, rwashinzwe mu 2005 rwibanze ku musaruro w’imiyoboro ya HDPE, Fittings & Valves, Imiyoboro ya PPR, Fittings & Valves, PP compression fiting & Valves, no kugurisha imashini zo gusudira za Plastike, ibikoresho, imiyoboro, imiyoboro Gusana Clamp nibindi.
