Umuyoboro wikubye kabiri ni ubwoko bushya bwumuyoboro, ufite uburemere bworoshye, imbaraga nyinshi, kubaka byoroshye, kubika ibikoresho nibindi byiza.Ugereranije nimbaraga zimwe zumucyo wurukuta rwumucyo, irashobora kuzigama hafi 40% yibikoresho fatizo, bikoreshwa cyane mumashanyarazi ya optique ya kabili, imiyoboro y'amazi, imiyoboro ya komine, imirima yubuhinzi bwumuvuduko muke nindi mirima.Mu myaka ya vuba aha, ikoreshwa ryinzogera ebyiri zagiye ziyongera buhoro buhoro, murwego rwitumanaho ryitumanaho, ryasimbuye umuyoboro wa sima.Ugereranije nindi miyoboro ya pulasitike, ikoreshwa ryayo naryo rinini.Mu rwego rwo kubaka imiyoboro y'amazi, kubera imikorere yayo yo gukingira amajwi irakennye gato, icyarimwe, iterambere ryibikoresho byo mu miyoboro ntabwo rihagije, bityo amafaranga ntabwo ari menshi.Ariko, mumazi ya komine nu ruganda, cyane cyane ikoreshwa rya diameter nini yashyinguwe inzogera ebyiri.Gukoresha imiyoboro ibiri yometseho urukuta ugereranije nibisobanuro bimwe byigiciro cyumucyo wurumuri rwa plastike ni gito, uruziga rwubwubatsi rushobora kugabanywa inshuro 5 ~ 10.

Ubushinwa bwatangiye kumenyekanisha umusaruro wubu bwoko bwumuyoboro kuva mu ntangiriro ya za 90, ubanza ahanini diameter ntoya ya φ 110 cyangwa munsi yayo, ibikoresho fatizo ahanini ni PVC, bikoreshwa cyane cyane mugukoresha insinga.Mu myaka yashize, inkuta ebyiri-inkuta zigenda zikura buhoro buhoro kugera ku cyerekezo cya diameter nini.Kugeza ubu, inzogera nini zo murugo zishobora kuba φ 1200. Ibikoresho fatizo bikoreshwa nabyo byatejwe imbere kuva PVC CYANE kugeza PE, PP nibindi.Ibikoresho byo kumurongo byerekana umusaruro nabyo byakuze kuva kera.Kugeza ubu, inganda nyinshi zo murugo zirashobora gutanga umurongo utanga umurongo wa diameter kugeza 1200mm.

Hariho ubwoko butatu bwa thermoplastique bukoreshwa mumiyoboro y'amazi yashyinguwe: POLYvinyl chloride, polyethylene na polypropilene.Modulus ya Elastike E mubikoresho bitatu (ukurikije PREN13476-1) ni:

Biragaragara, POLYvinyl chloride niyo isumba iyindi, ikurikiwe na polypropilene na polyethylene yo hasi.Kuberako modulus ya elastike E ya POLYvinyl chloride iruta iya polyolefine, gukomera kwimpeta imwe irashobora kugerwaho numwanya muto wa inertia I. Niba ukoresheje igishushanyo kimwe gishobora gukoresha uburebure bwurukuta ruto.Muburyo runaka bwa PVC kabiri - inkuta zurukuta mu nyungu zubukungu, bityo mubijyanye numuyoboro wamazi washyinguwe PVC kabiri - inzogera zurukuta mubisabwa mbere nazo ni umubare munini.Mu myaka yashize, polyolefin inzogera ebyiri-yateye imbere byihuse, kubwimpamvu zikurikira:

Amazi meza hamwe nubushyuhe bwibikoresho bya PVC birakennye cyane, biragoye rero kubyara umuyoboro munini wububiko bwa diameter.. diameter (bivugwa ko igera kuri mm 1800).

Kubera ko nta makuru ya tekiniki afite muri urwo rwego iyo iterambere ryimbere mu muyoboro w’amazi atangiye gushyingurwa ritangiye, ahanini rishingiye ku ruganda kugira ngo ruzenguruke.

Kurugero, umusaruro wambere wa polyethylene inshuro ebyiri zometseho inkuta yakoresheje PE80 ibikoresho byinshi bya polyethylene bikwiranye na gaz.Ibi bikoresho kugirango harebwe uburyo umuyoboro wa gaze uhinduka, uburemere bwa molekile ni buke, modulus ya elastike ni mike (munsi ya 800Mpa), ikoreshwa mugukora inzogera zinkuta ebyiri akenshi ntishobora kugera kumpeta zisabwa, zifite kongera uburebure bwurukuta, biragaragara ko atari ubukungu.Mu 2003, isosiyete ya sinopec yanhua yafashe iyambere mugutezimbere 6360M yubucucike bukabije bwa polyethylene HDPE ibyuma bibiri byometse kumyanda yo mu mazi yashyinguwe mubushinwa ukurikije ibyifuzo byabakoresha, bashingiye kuburambe bwiterambere ryamahanga mumyaka myinshi kandi bakurikije ibisabwa mumahanga amahame yo hejuru.6360M ya polymerisiyoneri ikoresha tekinoroji yambere yo kubyara umusaruro, kuburyo ibikoresho bidasanzwe bifite imiterere yihariye ya molekile yimiterere, modulus yo hejuru ya elastike kandi icyarimwe kugirango irusheho guhangana neza, kurwanya ingaruka nibindi bintu.Nyuma yibyo, Yanhua yakoze ibikoresho bidasanzwe 7000 kumuyoboro wamazi washyinguwe ukwiranye na diameter nini ya polyethylene ya rukuta.

QHE16A / B, resin idasanzwe ya kalibiri nini ya HDPE inzogera ebyiri zometse ku nkuta zakozwe na Qilu Petrochemical Research Institute hamwe n’uruganda rwa pulasitike, yamenyekanye n’abakora inzogera nini nini cyane kandi yabaye imwe mu mikorere ya mbere ya Calibre nini kandi nziza. inkuta ebyiri-inzogera idasanzwe resin yatejwe imbere mubushinwa.Ibikoresho bidasanzwe bifata formula nshya ya S-catalizator, ifite gahunda yuzuye ya tekiniki, kandi ifite imbaraga zo gushonga cyane, kugoreka modulus hamwe nubushyuhe bwumuriro.Umuyoboro munini wa kalibiri-urukuta rushyizwe hamwe nu bikoresho bidasanzwe bifite urumuri rwiza, gukomera kwimpeta no kurwanya gusaza, ibyo bikaba bigereranywa n’imikorere yuzuye y’ibicuruzwa byatumijwe mu mahanga, kandi birashobora kuzuza ibisabwa by’umusaruro munini wa kalibiri nini-rukuta umuyoboro wa kaburimbo y'imirongo itandukanye yo murugo.
