Izici zomzimba ezinhle kakhulu.Ukusebenza kwe-polyethylene ye-medium density iphakathi kwe-polyethylene ephezulu nephansi.Ayigcini nje ngokugcina ukuqina namandla e-polyethylene ephezulu, kodwa futhi inokuguquguquka okuhle nokumelana nokukhasa, futhi i-polyethylene ephezulu kakhulu ishisa kakhulu.Izici zokusebenza okuhle kakhulu kokuxhumeka kwe-fusion zihambisana nokufakwa kwamapayipi epulasitiki.
Ukumelana nokugqwala nempilo ende yesevisi.Ezindaweni ezisogwini lwezwe lethu, izinga lamanzi angaphansi komhlaba liphezulu futhi umswakama womhlabathi uphezulu.Ukusetshenziswa kwamapayipi ensimbi angenamthungo kufanele kunqande ukugqwala futhi kufuthelwe ngaphandle ukuze kufakwe, futhi impilo yesevisi iyiminyaka engama-30 kuphela, kuyilapho amapayipi e-PE angakwazi ukumelana nezinhlobonhlobo zamakhemikhali amakhemikhali.ukugqwala, ngaphandle kokwelashwa kwe-anti-corrosion.Futhi, ayikhuthazi ukukhula kwe-algal, amagciwane noma isikhunta futhi iphila iminyaka engama-50.
Ukuqina okuhle nokuvumelana nezimo.Ipayipi le-PE liwuhlobo lwepayipi eliqinile, ukuphakama kwalo ngesikhathi sekhefu lidlula ama-500%, likwazi ukuzivumelanisa nezimo eziqinile ekuxazululeni okungalingani kanye nokugudluzwa kwesisekelo sepayipi, futhi linokumelana okuhle kokuzamazama komhlaba.Kuqinisekisiwe ukuthi ipayipi le-PE liyipayipi elinokumelana nokushaqeka okungcono kakhulu.Kunesisho esithi ukuzamazama komhlaba eKobe eJapan ngo-1995, amapayipi e-PE namapayipi okuhambisa amanzi yiwona kuphela amapayipi angazange alimale.Ukwengeza, ukuguquguquka kwepayipi ye-PE yukuthi ipayipi ye-PE ingahlanganiswa, inciphise inani elikhulu lokufakwa kwamapayipi okuxhuma.Isiqondiso sepayipi ye-PE singashintshwa kalula ngokuvumelana nezidingo zendlela yokwakha.Ngesikhathi sokwakha, izithiyo zingavinjelwa ngaphakathi kwendawo yokugoba evunyelwe yepayipi ukuze kuncishiswe ubunzima bokwakha.
Amandla okujikeleza makhulu futhi umnotho uyonga kakhulu.Udonga lwangaphakathi lwepayipi ye-PE lubushelelezi futhi alulingani.Isilinganiso esilinganayo sokugwedla okuphelele kwendawo engaphakathi yepayipi le-PE singu-1/20 waleyo yepayipi lensimbi.Umthamo wokugeleza wepayipi ye-PE enobubanzi obufanayo bepayipi, ubude obufanayo kanye nokucindezela okufanayo kumayelana no-30% omkhulu kunalowo wepayipi yensimbi, ngakho inzuzo yezomnotho isobala.Uma kuqhathaniswa namapayipi ensimbi, amapayipi e-PE anganciphisa ukutshalwa kwezimali kwephrojekthi cishe ingxenye eyodwa kwezintathu, futhi amapayipi amancane obubanzi obungahlanganiswa anganciphisa nakakhulu izindleko zephrojekthi., Ukuxhumana kulula, ukwakhiwa kulula, futhi izindlela zihlukahlukene.Umzimba wepayipi le-PE ulula, kulula ukuwuphatha, kulula ukuwushisela, futhi unamalungu ambalwa okushisela.Uma ipayipi lilide, ipayipi lekhoyili lingasetshenziswa ukubeka umsele wepayipi le-PE.Izidingo ziphansi kakhulu kunomsele wepayipi lensimbi, futhi lapho izimo zokwakha zilinganiselwe, i-electrofusion welding ingasetshenziswa.Ngaphezu kwalokho, indlela yokucwilisa ipayipi ingasetshenziswa ukubeka phansi emanzini, okunciphisa kakhulu ubunzima bokwakha kanye nezindleko zobunjiniyela.
Ukubekwa uphawu okuhle.Ipayipi ye-PE ngokwayo i-welded futhi ixhunyiwe, okuqinisekisa ngokuyisisekelo ubunikazi bezinto ezibonakalayo, isakhiwo kanye nomzimba wepayipi ngokwawo, futhi iqaphela ukuhlanganiswa kokuhlangene kanye nepayipi.Amandla aqinile namandla okuqhuma kwesixhumi esibonakalayo aphezulu kunalawo omzimba wepayipi, ongamelana ngokuphumelelayo nokucindezeleka kwe-hoop kanye nokucindezeleka kwe-axial okukhiqizwa ukucindezela kwangaphakathi.Ngakho-ke, uma kuqhathaniswa namajoyinti ohlobo lwendandatho yerabha noma amanye amalunga emishini, ayikho ingozi yokuvuza ebangelwa ukuhlanekezela kwamalunga, futhi ukusebenza kokuvala kuhle kakhulu.
Kulula ukuyinakekela futhi ingakhandwa futhi ifakwe ngaphandle kwamanzi negesi.
Ukumelana okuhle kokuqhekeka kwengcindezi:Ipayipi le-PEinokuzwela okuphansi kwe-notch, amandla aphezulu okugunda kanye nekhono le-segmental anti-scratch, kanye nokumelana nokucindezeleka kwemvelo okuvelele.Ukumelana nomthelela wokushisa okuphansi okuhle: Izinga lokushisa eliphansi le-embrittlement yepayipi le-PE liphansi kakhulu, futhi lingasetshenziswa ngokuphepha ebangeni lokushisa elingu--60 degrees Celsius.Engxenyeni esenyakatho yezwe lami, lapho i-polyethylene engcwatshwe amanzi ibekwe ensimini ebusika, kuphetha ngokuthi ayifaneleki ukubeka ukwakhiwa ngaphansi kwama-degrees angu-zero, ngoba ipayipi ye-polyethylene ilula kalula.Ukumelana okuhle nokugwazwa.Ukuhlolwa kokuqhathaniswa kokumelana nokugqokwa kwepayipi le-polyethylene nepayipi lensimbi kubonisa ukuthi ukumelana kwayo nokugqoka kuphindwe izikhathi ezingu-4 kunepayipi lensimbi.
