Umuvuduko mwinshi Polyethylene Umuyoboro
Icyiciro cya pipe ya HDPE gifite ubugari cyangwa bimodal gukwirakwiza uburemere bwa molekile.Ifite imbaraga zo guhangana n’ibisimba hamwe nuburinganire bwiza bwo gukomera no gukomera.Biraramba cyane kandi bifite sag nkeya iyo bitunganijwe.Imiyoboro yakozwe ikoresheje iyi resin ifite imbaraga nziza, gukomera no kurwanya ingaruka hamwe numutungo mwiza wa SCG na RCP.
Ibisigarira bigomba kubikwa mububiko bwateguwe, bwumye kandi kure yumuriro nizuba ryinshi.Ntigomba kurundarunda mu kirere.Mugihe cyo gutwara, ibikoresho ntibigomba guhura nizuba ryinshi cyangwa imvura kandi ntibigomba kujyanwa hamwe numucanga, ubutaka, ibyuma bisakara, amakara cyangwa ikirahure.Gutwara hamwe nibintu bifite ubumara, ibora kandi byaka birabujijwe rwose.
Gusaba
Urwego rwa HDPE rushobora gukoreshwa mugukora imiyoboro yumuvuduko, nkumuyoboro wamazi wumuvuduko, imiyoboro ya lisansi nindi miyoboro yinganda.Irashobora kandi gukoreshwa mugukora imiyoboro idafite umuvuduko nkumuyoboro wikubye kabiri, imiyoboro ihanamye, imiyoboro ya silicon-imiyoboro, imiyoboro yo kuhira ubuhinzi hamwe na aluminumplastique.Byongeye kandi, binyuze mu gukuramo ibintu (silane cross-guhuza), irashobora gukoreshwa mugukora imiyoboro ya polyethylene ihuza (PEX) mugutanga amazi akonje kandi ashyushye.
