Umurongo munini wa Diameter HDPE Umuyoboro wo gukuramo

Umuyoboro wa HDPE ni ubwoko bwumuyoboro wa pulasitike woroshye ukoreshwa mu guhererekanya amazi na gaze kandi akenshi ukoreshwa mu gusimbuza imiyoboro ya beto ishaje cyangwa ibyuma.Ikozwe muri thermoplastique HDPE (polyethylene yuzuye cyane), urwego rwayo rwinshi rwo kudacogora hamwe nubusabane bukomeye bwa molekile bituma ikwiranye numuyoboro mwinshi.Umuyoboro wa HDPE ukoreshwa ku isi hose mu bikorwa nk'imiyoboro y'amazi, imiyoboro ya gazi, imiyoboro y'amazi, imirongo yohereza amashanyarazi, kuhira imyaka mu cyaro, imirongo itanga umuriro, umuyoboro w'amashanyarazi n'itumanaho, n'amazi y'imvura n'imiyoboro y'amazi.

Imiyoboro minini ya diameter ya HDPE irakomeye, yoroheje, ihungabana kandi irwanya imiti.Batanga ubukungu bwubushakashatsi hamwe nigihe kirekire cyo gukora.Iyi miyoboro iraboneka muburebure busanzwe bwa 3, 6, 12 na 14m.Uburebure budasanzwe burashobora gukorwa kugirango bikemuke hafi.

Umuyoboro wa HDPE ni umuyoboro wa pulasitiki woroshye wakozwe muri termoplastique yo mu rwego rwo hejuru cyane ya polyethylene ikoreshwa cyane mu gukwirakwiza amazi make no kohereza gaze.Mu bihe byashize, imiyoboro ya HDPE yabonye uburyo bwinshi bwo gutwara amazi meza, imyanda iteje akaga, imyuka itandukanye, amashanyarazi, amazi yumuriro, amazi yimvura, nibindi.Imiyoboro ya polyethylene ifite amateka maremare kandi atandukanye ya serivisi ya gaze, peteroli, ubucukuzi, amazi, nizindi nganda.Kubera uburemere buke hamwe no kurwanya ruswa nyinshi, inganda za HDPE ziratera imbere cyane.Mu mwaka wa 1953, Karl Ziegler na Erhard Holzkamp bavumbuye polyethene yuzuye (HDPE).Imiyoboro ya HDPE irashobora gukora neza muburyo bwubushyuhe bwa -2200 F kugeza kuri +1800 F. Ariko, gukoresha imiyoboro ya HDPE ntibisabwa mugihe ubushyuhe bwamazi burenze 1220 F (500 C).

Imiyoboro ya HDPE ikorwa na polymerisation ya Ethylene, ibikomoka kuri peteroli.Inyongeramusaruro zitandukanye (stabilisateur, kuzuza, plasitike, koroshya, amavuta, amabara, amabara ya flame, ibyuma bisohora ibintu, guhuza imiyoboro, ultraviolet yangirika, nibindi) byongeweho kugirango bitange umuyoboro wanyuma wa HDPE nibigize.Uburebure bwa HDPE bukozwe no gushyushya resin ya HDPE.Ihita ikurwa mu rupfu, igena diameter y'umuyoboro.Uburebure bw'urukuta rw'umuyoboro bugenwa no guhuza ubunini bw'urupfu, umuvuduko wa screw, n'umuvuduko wa romoruki ikurura.Mubisanzwe, 3-5% byumukara wa karubone byongewe kuri HDPE kugirango ikore UV irwanya, ihindura imiyoboro ya HDPE ihinduka umukara mubara.Ibindi bibara byamabara birahari ariko mubisanzwe ntibikoreshwa kenshi.Umuyoboro w'amabara cyangwa ucuramye HDPE mubusanzwe ni 90-95% ibikoresho byirabura, aho umurongo wamabara utangwa kuri 5% yubuso bwo hanze.
