HDPE inozivikanwawo seyakakwira density polyethylene zvinhu.Iyo imhando ye thermoplastic resin ine yakakwira crystallinity uye isiri polarity.Kuonekwa kweiyo HDPE yepakutanga ine mukaka chena uye inopenya kune imwe nhanho muchikamu chitete.Iyo polymer haina hygroscopic uye ine yakanaka mvura mhute kuramba, iyo inogona kushandiswa pakurongedza.HDPE ine zvinhu zvakanaka zvemagetsi, kunyanya iyo yakakwira dielectric simba rekudzivirira, iyo inoita kuti ive yakakodzera kwazvo waya netambo.Yepakati kusvika kune yakakwira molecular giredhi ine yakanakisa mhedzisiro yekupikisa pakamuri tembiricha kana kunyange -40f yakaderera tembiricha.HDPE inowanzoshandiswa sekuiswa kwepombi, uyewo vamwematoyi fittings, PK plug , odhiyo.
Nekuda kwesimba rakasiyana, mapaipi eHDPE anofanirwa kutakura kumwe kudzvanywa.Kazhinji, PE resin ane huremu hwakakura hwemamorekuru uye yakanaka michina zvinhu, senge HDPE resin, inofanira kusarudzwa.Simba racho rakapetwa ka9 kune yakajairika polyethylene pombi (PE pombi).
Kuramba kupfeka kwakasiyana.Pakati pemapurasitiki einjiniya ese, HDPE ine yakanyanya kupfeka kuramba.Iyo yakakwira huremu hwemamorekuru, iyo inonyanya kusakara, uye kunyange kupfuura zvinhu zvakawanda zvesimbi (senge kabhoni simbi, simbi isina tsvina, bhuronzi, nezvimwewo), yakajairika PE inongova chikamu chimwe chete mugumi cheHDPE.
Mapaipi eHDPE ane mhedzisiro dzakasiyana dzekutsiva.Ndivo zvigadzirwa zvekutsiva zvechinyakare simbi mapaipi uye polychloroprene mvura yekunwa pombi.Nekudaro, PE polychloroprene inogona chete kushandiswa seyekunze chiteshi pombi, uye kunyange yakaderera-density PE mapaipi anogona kushandiswa chete kumvura.
Chiyero chekushandisa chakasiyana.HDPE mapaipianonyanya kushandiswa kune: nzira yekupa mvura yeinjiniya yemanisipala, hurongwa hwemvura yemukati yezvivakwa, kunze yakavigwa mvura yekugovera nzira uye yakavigwa mvura yekupa mvura yedzimba dzekugara nenzvimbo dzezvirimwa, kugadziriswa kwepombi yekare, mvura yekuchenesa engineering pombi system, mapombi emvura mumaindasitiri mukati. mapindu, kudiridza nemimwe minda.Medium density PE mapaipi akakodzera chete kutakura gasi rakagadzirwa gasi, gasi remusikirwo uye liquefied petroleum gasi.Low density PE mapaipi mahosi.
