Umehluko phakathi kwe-HDPE ne-PE

I-HDPE yaziwa nangokuthi i-high density polyethylene material.Iwuhlobo lweresin ye-thermoplastic enecrystallinity ephezulu futhi engeyona i-polarity.Ukubukeka kwe-HDPE yasekuqaleni kumhlophe qhwa futhi kukhanye ngokwezinga elithile esigabeni esincanyana.I-polymer ayiyona i-hygroscopic futhi inokumelana kahle nomhwamuko wamanzi, ongasetshenziselwa izinjongo zokupakisha.I-HDPE inezinto ezinhle zikagesi, ikakhulukazi amandla aphezulu e-dielectric of insulation, okwenza ifaneleke kakhulu izintambo nezintambo.Ibanga eliphakathi nendawo ukuya kweliphezulu linamandla okumelana nomthelela ekamelweni lokushisa noma ngisho -40f lokushisa eliphansi.I-HDPE ivame ukusetshenziswa njengeukufakwa kwepayipi, kanye nabanyeizinto zokudlala, ipulaki ye-PK , umsindo.

Ngenxa yamandla ahlukene, amapayipi e-HDPE kufanele athwale ingcindezi ethile.Ngokuvamile, ama-resin e-PE anesisindo esikhulu samangqamuzana kanye nezakhiwo ezinhle zemishini, njenge-HDPE resins, kufanele kukhethwe.Amandla aphindwe izikhathi ezingu-9 kunepayipi elivamile le-polyethylene (ipayipi le-PE).

Ukumelana nokugqoka kuhlukile.Phakathi kwawo wonke amapulasitiki obunjiniyela, i-HDPE inokumelana okuphezulu kakhulu nokugqokwa.Uma siphakama isisindo samangqamuzana, izinto ezisetshenziswayo ezingagugi nakakhulu, futhi ngisho nangaphezu kwezinsimbi eziningi (njenge-carbon steel, insimbi engagqwali, ithusi, njll.), i-PE evamile iyingxenye eyodwa kweshumi ye-HDPE.

Amapayipi e-HDPE anemiphumela ehlukile yokushintshanisa.Ziyimikhiqizo eshintshwayo yamapayipi ensimbi endabuko kanye namapayipi amanzi okuphuza e-polychloroprene.Kodwa-ke, i-PE polychloroprene ingasetshenziswa kuphela njengepayipi lesiteshi sangaphandle, futhi ngisho namapayipi e-PE aphansi angasetshenziswa kuphela emanzini.

Ububanzi bohlelo lokusebenza buhlukile.HDPE amapayipiasetshenziselwa kakhulu: uhlelo lokuphakelwa kwamanzi lobunjiniyela bakamasipala, uhlelo lokuphakelwa kwamanzi angaphakathi kwezakhiwo, uhlelo lokuphakelwa kwamanzi agqitshwe ngaphandle kanye nesistimu yokuphakelwa kwamanzi angcwatshwe ezindaweni zokuhlala nezindawo zezitshalo, ukulungiswa kwamapayipi amadala, uhlelo lobunjiniyela bokuhlanza amanzi, amapayipi amanzi ezimbonini izingadi, ukuchelela kanye namanye amasimu.Amapayipi e-PE e-Medium density afaneleka kuphela ukuthutha igesi yokwenziwa enegesi, igesi yemvelo kanye negesi ye-petroleum ewuketshezi.Amapayipi e-PE ane-low density amapayipi.
