Ukuvumelana nezimo
Ukuguquguquka kwephayiphu ye-polyethylene kuyakuvumela ukuba kugobe ngaphezulu, ngaphansi, kanye nezingqinamba ezizungezile futhi zenze izinguquko eziphakeme kanye nezinguquko eziqondisayo.Kwezinye izimo, ukuguquguquka kwepayipi kungasusa ngokumangazayo ngokusetshenziswa kokufakelwa futhi kunciphise kakhulu izindleko zokufaka.
I-Chuanagrong PE PIPE ingagodlela emsakazweni omncane phakathi kwezikhathi ezingama-20 kuye kwangama-40 ububanzi bepayipi, obuya ikakhulukazi ku-SDR yepayipi elithile.

Isisindo esikhanyayo
Isikhathi sokuphila
Ubuningi bezinto ezibonakalayo pen kuphela 1/7 lelensimbi. Isisindo sepayipi le-PE siphansi kakhulu kunalokho kwensimbi ekhonkolo ekhonkolo, noma ipayipi lensimbi.Uhlelo lwe-Piping kulula ukuphatha futhi lufake, futhi izidingo zamandla ezincishisiwe zingaba nomphumela wokonga ukufakwa.
Isisekelo sedizayini ye-hydrostatic yepayipi le-chuamvelo sisuselwa kudatha ebanzi yokuhlola i-hydrostatic ihlolwe ngezindlela ezijwayelekile zezimboni.Indlela yokuziphatha yesikhathi eside yokuvinjwa kwamandla kwengcindezi yangaphakathi enikezwe ijika lamandla we-hydrostatic anikezwe i-Enso 15494 Standard (bheka isigaba X). Imikhawulo yohlelo lokusebenza yamapayipi nokufakwayo, njengoba kukhonjisiwe kumdwebo wokushisa-izinga lokushisa, kungasuselwa kula majika, okukhombisa ukuthi ipayipi linesikhathi sokuphila cishe eminyakeni engama-20 ℃. Izimo zangaphakathi nangaphandle zemvelo zingaguqula impilo elindelekile noma zishintshe isisekelo sokuklama esinconyiwe sohlelo lokusebenza olunikeziwe.
Ukumelana Nesimo sezulu
Izakhiwo ezishisayo
Isimo sezulu sepulasitiki senzeka ngenqubo yokuwohloka komhlaba, noma i-oxidation, ngenxa yomphumela ohlanganisiwe wemisebe ye-Ultra Violet, izinga lokushisa elikhulayo, nokujaha lapho amapayipi egcinwe ezindaweni eziveziwe. I-Black Polyethlence Pipe, equkethe i-2 kuya ku-2,5% Carbon emnyama, ingagcinwa ngokuphepha ngaphandle kwezimo zezulu eziningi ngaphandle komonakalo kusuka ku-Ultra-violet exposure. Eminye imibala enjenge-White, eluhlaza okwesibhakabhaka, ophuzi noma i-lilac ayinawo ukuqina okufanayo njengoba amasistimu amnyama anezinhlamvu futhi isikhathi sokuvezwa kufanele aqedwe ukugcinwa okuphezulu kwezakhiwo ze-oxidation zangaphandle zikhula ngezinga elisheshayo kunalezo eziku-carbon emnyama
Amapayipi azothuthukiswa amapayipi.
Amapayipi e-polyethylene angasetshenziswa emazingeni okushisa asukela ku-50 ° C kuya ku-60 ° C. Emazingeni okushisa aphezulu, amandla ashubile nokuqina kokuqukethwe kuncishiswe, sicela uthintane nomdwebo wokushisa wengcindezelo. Kwamazinga okushisa angezansi kwe-OW ° OD kumele aqinisekiswe ukuthi i-Medium ayibandakanyi, ukugwema ukulimaza ngohlelo lwamapayipi.
Njengawo wonke ama-thermoplastics, i-PE akhombisa ukwanda okuphezulu kwe-thethermal insimbi. I-PE yethu ine-coefficent yokwanda okushisayo okushisayo okungu-0,15 kuya ku-0.20mm / m k, okuyi-1.5 izikhathi ezinkulu kakhulu kunaleyo yesibonelo. I-PVC. Njengoba lokhu kubhekwa ngesikhathi sokuhlela ukufakwa bekungafanele kube nezinkinga kulokhu.
Ukuqhutshwa kwe-Thermal kungu-0.38 w / m k.baches wezakhiwo eziholela ekufakweni, uhlelo lwamapayipi e-PE luphawuleka kakhulu ngokuqhathaniswa nohlelo olwenziwe ngentengo efana nethusi.
Isimilo sokuziphatha
![V17b] @ 7xq [IYGS3] U8SM $ $ $ R](http://www.cdchuangrong.com/uploads/V17B@7XQIYGS3U8SMR.jpg)
I-polyethylene ingeyamapulasitiki avuthayo.I-OXYGEGEN Index ifinyelela ku-17%.
Ama-drips nama-coninisi ashise ngaphandle kwensizwa ngemuva kokususa ilangabi. Ngokuyisisekelo, izimiso ezinobuthi zikhululwa yizo zonke izinqubo ezivuthayo. I-Carbon Moxide ngokuvamile ingumkhiqizo wokuvutha oyingozi kakhulu kubantu. Lapho i-PE isha, ngokuyinhloko ikhabhoni diokdide, i-carbon monoxide namanzi akhiwe.
Izinga lokuzila lokuzenzela lingama-350 ℃.
Ama-ejenti alwayo okulwa nomlilo anamanzi, amagwebu, isikhutha noma i-powder.
Ukumelana Nemvelo
Amapayipi we-PE angaba ngaphansi komonakalo emithonjeni yemvelo efana nezintuthwane noma amagundane. Ukumelana nokuhlasela kunqunywa ngobulukhuni be-PE esetshenzisiwe, iJiyomethri yendawo ye-PE, kanye nemibandela yokufakwa. Ngamapayipi amancane abubanzi, izingxenye ezingcolile zodonga zizonakaliswa ngama-termites ezimweni ezimbi kakhulu. Noma kunjalo ukulimala okuvame ukubhekwa ekuhlaselweni okuyisimilo ku-PE kuye kwatholakala ngemuva kweminye imithombo yomonakalo owenziwe ngomshini.
Izinhlelo ze-Pipe ze-PE azithintekanga ngenxa yezinto eziphilayo ezweni lonke, kanye nezicelo zasolwandle, kanye nemvelo yepharafinic ye-Pipe Pipe Sumparies igcina ukwakhiwa kwama-marine grothes in service.
Izakhiwo zikagesi
Ngenxa yokutholwa kwamanzi okuphansi kwe-PE, izakhiwo zalo kagesi azithinteki ngokuxhumana okuqhubekayo kwamanzi.Since Peldron blymer, is an-insularbon polymer, noma kunjalo, ingabi kakhulu ngenxa yokungcoliswa kwemithombo yezindaba noma isimo sezulu. Ukumelana kwevolumu ethile kungukuthi> 1017 ωcm; Amandla we-dielectric angama-220 kV / mm.
Ngenxa yokuthuthuka okungenzeka kwamacala kagesi, kunconywa ukuqaphela lapho usebenzisa i-PE kuzinhlelo zokusebenza lapho ingozi yemililo noma ukuqhuma injalo.
ChuangangIngabe imboni yokwabelana kanye nenkampani ehlanganisiwe yenkampani ehlanganisiwe, esungulwe ngo-2005 egxile ekukhiqizweni kwamapayipi e-HDPE, Fittings & Valve, ukuthengiswa kwamathanga, ukuthengiswa kwamathuluzi okulungiswa kwamapayipi nokunye.
