Ukuvumelana nezimo
Ukuguquguquka kwepayipi le-polyethylene kulivumela ukuthi ligobe ngaphezulu, ngaphansi, futhi lizungeze izithiyo kanye nokwenza izinguquko zokuphakama nokuqondisa.Kwezinye izimo, ukuguquguquka kwepayipi kungase kuqede ngokuphawulekayo ukusetshenziswa kwezinto zokufakwa futhi kunciphise kakhulu izindleko zokufakwa.
Ipayipi le-CHHUANGRONG PE lingagotshwa libe endaweni engaba okungenani izikhathi ezingama-20 kuya kwezingama-40 ubukhulu bepayipi, okuncike kakhulu ku-SDR yepayipi elithile.

Isisindo Esilula
Ukulindela Ukuphila
Ukuminyana kwezinto ze-PE yi-1/7 kuphela yaleyo yensimbi. Isisindo sepayipi le-PE lincane kakhulu kunelensimbi ekhonjiwe kakhonkolo, noma ipayipi lensimbi.Uhlelo lwamapayipi e-PE kulula ukuluphatha nokulufaka, futhi ukuncipha kwamandla omuntu kanye nezidingo zemishini kungase kubangele ukonga ukufakwa.
Isisekelo somklamo we-hydrostatic wepayipi le-CHUANGRONG sisekelwe kudatha ebanzi yokuhlola i-hydrostatic ehlolwe ngezindlela zemboni ezijwayelekile.Ukuziphatha kwesikhathi eside kokumelana nokucindezela kwangaphakathi okuhlinzekwa yijika lamandla e-hydrostatic ngokusekelwe ku-EN ISO 15494 standard (bona isigaba X). Imikhawulo yokufaka isicelo yamapayipi nezinto ezifakwayo, njengoba kukhonjisiwe kumdwebo wezinga lokushisa lokucindezela, ingatholwa kulawa majika, abonisa ukuthi ipayipi linobude bokuphila obungaba iminyaka engama-50 lapho lithutha amanzi ku-20℃. Izimo zemvelo zangaphakathi nezangaphandle zingashintsha ukuphila okulindelekile noma ziguqule isisekelo sokuklama esinconyiwe sohlelo olunikeziwe.
Ukumelana Nesimo Sezulu
Izakhiwo ezishisayo
Isimo sezulu samapulasitiki kwenzeka ngenqubo yokuwohloka kwendawo, noma ukucwiliswa kwe-oxidation, ngenxa yomphumela ohlangene wemisebe ye-ultraviolet, izinga lokushisa elikhulayo, kanye nomswakama lapho amapayipi egcinwa ezindaweni eziveziwe. Ipayipi le-polyethylensi elimnyama, eliqukethe u-2 kuya ku-2.5% ohlukaniswe kahle ngekhabhoni emnyama, lingagcinwa ngokuphepha ngaphandle ezindaweni eziningi zezulu iminyaka eminingi ngaphandle kokulimala ngenxa yokuchayeka kwe-ultraviolet. Eminye imibala emhlophe, eluhlaza okwesibhakabhaka, ephuzi noma e-lilac ayinakho ukuzinza okufanayo namasistimu anombala omnyama futhi isikhathi sokuchayeka kufanele sikhawulelwe unyaka owodwa ukuze kugcinwe izakhiwo ngokugcwele. Ngalezi zinhlelo zemibala izingqimba ze-oxidation zangaphandle zithuthuka isilinganiso esisheshayo kunalezo eziku-carbon black
amapayipi e-PE azinzile.Lawa mapayipi anombala awanconyelwe ukusetshenziswa okungaphezulu komhlaba.
Amapayipi e-polyethylene angasetshenziswa emazingeni okushisa asukela ku-50°C kuya ku-+60°C. Emazingeni okushisa aphezulu, amandla okuqina nokuqina kwento kuyancishiswa Ngakho-ke, sicela ubheke umdwebo we-pressure-temperature. Emazingeni okushisa angaphansi kwe-O°Cit kufanele kuqinisekiswe ukuthi okuphakathi akuqandi, ukuze kugwenywe ukulimala ohlelweni lwamapayipi.
Njengawo wonke ama-thermoplastics, i-PE ikhombisa ukunwetshwa okuphezulu kokushisa kwensimbi. I-PE yethu ine-coefficent yomugqa wokunweba okushisayo okungu-0.15 kuya ku-0.20mm/m K, okuphindwe izikhathi ezingu-1.5 kunesib. I-PVC. Njengoba lokhu kubhekwa ngesikhathi kuhlelwa ukufakwa akufanele kube nezinkinga kulokhu.
I-thermal conductivity ingu-0.38 W/m K. Ngenxa yezakhiwo zokuvikela eziwumphumela, isistimu yamapayipi e-PE iyonga kakhulu uma iqhathaniswa nesistimu eyenziwe ngezinto ezifana nethusi.
Ukuziphatha Komlilo
![V17B]@7XQ[IYGS3]U8SM$$R](http://www.cdchuangrong.com/uploads/V17B@7XQIYGS3U8SMR.jpg)
I-polyethylene ingeyamapulasitiki avuthayo.Inkomba ye-oxygen ifinyelela ku-17%.(Izinto ezivutha ngaphansi kuka-21% we-oxygen emoyeni zibhekwa njengezingasha).
Amaconsi e-PE kanye nama-coninues ukuze ashise ngaphandle kwe-soot ngemva kokukhipha ilangabi. Ngokuyisisekelo, izinto ezinobuthi zikhishwa yizo zonke izinqubo ezivuthayo. I-carbon monoxide ngokuvamile iwumkhiqizo ovuthayo oyingozi kakhulu kubantu. Lapho i-PE isha , ngokuyinhloko i-carbon dioxide, i-carbon monoxide namanzi ar kwakheka.
Izinga lokushisa lokuzishisa lingama-350 ℃.
Ama-ejenti okucisha umlilo afanelekile amanzi, igwebu, isikhutha noma impushana.
Ukumelana Nezinto Eziphilayo
Amapayipi e-PE angase abe ngaphansi kokulimala okuvela emithonjeni yebhayoloji njengezintuthwane noma amagundane. Ukumelana nokuhlasela kunqunywa ubulukhuni be-PE esetshenzisiwe, i-geometry yezindawo ze-PE, nezimo zokufakwa. Emapayipini amancane anobubanzi, izingxenye ezincane zodonga zingase zonakaliswe umuhlwa ezimweni ezimbi kakhulu. Kodwa-ke umonakalo ovame ukuhlotshaniswa nokuhlasela kwemihlwa e-PE kamuva utholakale ungenxa yeminye imithombo yokulimala kwemishini.
Izinhlelo zamapayipi e-PE ngokuvamile azithintwa yizinto eziphilayo emhlabeni, nasezindaweni zasolwandle, futhi isimo sikapharafini sepayipi le-PE sibambezela ukwakheka kwezimila zasolwandle ezisebenza.
Izakhiwo zikagesi
Ngenxa yokumuncwa kwamanzi aphansi kwe-PE, izakhiwo zawo zikagesi azithinteki kakhulu ngokuthintana kwamanzi okuqhubekayo.Njengoba i-PE iyi-polar ye-hydrocarbon polymer engeyona i-polar, i-insulator evelele.Lezi zakhiwo, nokho, zingaba zimbi kakhulu ngenxa yokungcola. , imiphumela yemidiya ye-oxidizing noma isimo sezulu. Ukumelana nevolumu ethile ngu>1017 Ωcm; amandla e-dielectric angu-220 kV/mm.
Ngenxa yokuthuthukiswa okungenzeka kwamashaji kagesi, ukuqapha kuyanconywa uma usebenzisa i-PE ezinhlelweni lapho ingozi yomlilo noma ukuqhuma ivela khona.
CHUANGRONGiyinkampani edidiyelwe yemboni yamasheya kanye nezohwebo, eyasungulwa ngo-2005 egxile ekukhiqizweni kwamapayipi e-HDPE, okokufaka & namavalvu, amapayipi e-PPR, ama-Fittings & Valves, ama-compress fittings nama-Valves e-PP, nokudayiswa kwemishini yokushisela yamapayipi epulasitiki, Amathuluzi Epayipi, Ipayipi. I-Clamp yokulungisa nokunye.
