Imirongo myinshi ya HDPE Umuyoboro wo guhuza umurongo

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, gutemba, amazi y’umuriro, amazi y’imvura, n’ibindi. 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 bugari 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 birusheho UV, bihindura 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.
