[Ibisobanuro rusange] Polyethylene ni pulasitiki, izwiho ubucucike bwayo bwinshi, ubworoherane bwayo n'ubudahinduka bwa shimi. Ni nziza cyane mu gukoresha imiyoboro y'umuvuduko n'imiyoboro idakoresha umuvuduko. Imiyoboro ya HDPE isanzwe ikorwa muri polyethylene 100 resin, ifite ubucucike bwa 930-970 kg / m3, bungana n'inshuro 7 z'icyuma.

Polyethylene ni pulasitiki, izwiho ubucucike bwayo bwinshi, ubworoherane bwayo n'ubudahindagurika bwayo. Ni nziza cyane mu gukoresha imiyoboro y'umuvuduko n'ubudashyuha. Imiyoboro ya HDPE isanzwe ikorwa muri polyethylene 100 resin, ifite ubucucike bwa 930-970 kg / m3, bungana n'inshuro 7 z'icyuma. Imiyoboro yoroheje biroroshye kuyitwara no kuyishyiraho. Polyethylene ntigira ingaruka ku buryo bwo kwangirika kw'amashanyarazi, kandi ni ibisanzwe ko imiyoboro ihura n'umunyu, aside na alkali. Ubuso bworoshye bw'umuyoboro wa polyethylene ntibuzangirika, kandi gukururana kwayo ni guke, bityo umuyoboro wa plastiki ntugira ingaruka zoroshye ku gukura kwa mikorobe. Ubushobozi bwo kurwanya kwangirika no gutemba guhoraho bituma ibisabwa mu kubungabunga imiyoboro ya HDPe ari bike cyane. Umuyoboro wa polyethylene ushobora gukorwa muri resin ikomeye, ishyirwa mu cyiciro cya PE100-RC, kandi yongerwamo kugira ngo igabanye gukura kw'imivuduko. Imiyoboro ikorwa ishobora kumara igihe kirekire, kandi polyethylene ifite inyungu mu bukungu mu gihe cy'umushinga.

Ubu noneho ko imiyoboro ya HDPe imaze kumenyekana ko iramba, ubukungu ni ingenzi cyane iyo imiyoboro ya polyethylene ikoreshwa mu bikorwa remezo byo kubungabunga amazi. Ugereranyije n'imiyoboro y'icyuma ikoresha ibyuma bitose, inyungu igaragara cyane y'imiyoboro ya polyethylene ni uko ishobora gukumira amazi ava. Hari ubwoko bubiri bw'amazi ava mu miyoboro: amazi ava mu ngingo, amazi ava mu gace k'umugezi n'amazi ava mu mwobo, byoroshye kuyafata.

Ingano yaUmuyoboro wa HDPEUburebure buri hagati ya mm 1600 na mm 3260, kandi imiyoboro minini iri ku isoko ubu irashobora gukoreshwa. Uretse sisitemu z'amazi zo mu mujyi, imiyoboro minini ya pulasitiki ikozwe muri polyethylene ishobora no gukoreshwa mu byumba byo gusukura amazi yo mu nyanja no mu gutunganya amazi yanduye. Imiyoboro minini ishobora kuba kuva kuri cm 315 kugeza kuri cm 1200. Uburebure buniniUmuyoboro wa HDPeIramba cyane kandi yizewe. Nyuma yo gutwikirwa mu butaka, ishobora gukora imyaka ibarirwa muri za mirongo kandi idasaba kwitabwaho cyane, bityo ikaba ikwiriye cyane gukoreshwa mu gutunganya amazi yanduye. Kuramba k'umuyoboro wa polyethylene biriyongera uko ingano yawo yiyongera, bigaragaza ubushobozi butangaje bwo kurwanya gutigita. Urugero, fata umutingito wa Kobe mu Buyapani mu 1995, ibikorwa remezo by'imijyi; indi miyoboro yose irangirika nibura rimwe muri kilometero 3, kandi sisitemu yose y'imiyoboro ya HDPE nta na kimwe yangiritse.

Ibyiza by'umuyoboro wa HDPE: 1. Gukomera neza mu by'imiti: HDPE nta polarity ifite, ikomera neza mu by'imiti, ntiyororoka algae na bagiteri, ntikwirakwira, kandi ni ikintu kitangiza ibidukikije. 2. Ingufu nziza zo guhuza: koresha amashanyarazi ahuza imiyoboro cyangwa umuyaga uhuza imiyoboro, hamwe n'ingingo nke kandi nta gusohoka kw'amazi. 3. Ubudahangarwa bw'amazi buke: Ubuso bw'imbere bwaUmuyoboro wa HDPeni nziza, ifite ubushobozi buke bwo kwangirika no kugenda cyane. 4. Irwanya ubushyuhe buke no kwangirika: ubushyuhe bwo kwangirika ni (-40), kandi ingamba zihariye zo kurinda ntabwo zikenewe mu kubaka ubushyuhe buke. 5. Irwanya kwangirika neza: Isuzuma ryo kugereranya uburyo imiyoboro ya polyethylene n'imiyoboro y'icyuma idakira ubwandu rigaragaza ko imiyoboro ya polyethylene idakira ubwandu ikubye inshuro 4 ugereranyije n'imiyoboro y'icyuma. 6. Irwanya gusaza no kumara igihe kirekire: Umuyoboro wa HDPE ushobora kubikwa cyangwa gukoreshwa hanze mu gihe cy'imyaka 50 utangiritse n'imirasire ya ultraviolet.
