Nkhani - Makhalidwe a CHUANGRONG PE Piping System

Kusinthasintha

Kusinthasintha kwa chitoliro cha polyethylene kumapangitsa kuti ikhale yopindika, pansi, ndi kuzungulira zopinga komanso kupanga kukwera ndi kusintha kolowera.Nthawi zina, kusinthasintha kwa chitoliro kumatha kuthetsa kugwiritsa ntchito zopangira ndikuchepetsa kwambiri mtengo woyika.

Chitoliro cha CHUANGRONG PE chikhoza kupindika kumtunda wocheperako pakati pa 20 mpaka 40 kutalika kwa chitoliro, zomwe zimatengera SDR ya chitoliro china.

Kulemera Kwambiri

Chiyembekezo cha Moyo

Kuchuluka kwa zinthu za PE ndi 1/7 yokha ya chitsulo. Kulemera kwa chitoliro cha PE ndi chochepa kwambiri kuposa chachitsulo cha konkire, kapena chitoliro chachitsulo. Dongosolo la payipi la PE ndi losavuta kugwiritsira ntchito ndikuyika, ndipo kuchepetsedwa kwa mphamvu za munthu ndi zipangizo zomwe zingafunike zingapangitse kuti asungidwe.

Chitoliro cha hydrostatic cha CHUANGRONG chitoliro chimatengera kuchuluka kwa kuyezetsa kwa hydrostatic komwe kumawunikidwa ndi njira zofananira zamakampani.Makhalidwe anthawi yayitali azovuta zamkati zomwe zimaperekedwa ndi hydrostatic mphamvu yopindika potengera muyezo wa EN ISO 15494 (onani gawo X). Malire ogwiritsira ntchito mapaipi ndi zoyikira, monga momwe akuwonetsedwera mu chithunzi cha kutentha-kutentha, akhoza kutengedwa kuchokera ku ma curve awa, omwe amasonyeza kuti chitolirocho chimakhala ndi moyo wa zaka pafupifupi 50 ponyamula madzi pa 20 ℃. Mkati ndi kunja kwa chilengedwe kungasinthe moyo woyembekezeredwa kapena kusintha maziko ovomerezeka a ntchito yoperekedwa.

Thermal Properties

Kutentha kwa mapulasitiki kumachitika chifukwa cha kuwonongeka kwa nthaka, kapena kuti okosijeni, chifukwa cha kuphatikizika kwa cheza cha ultra violet, kutentha kwakukulu, ndi chinyezi pamene mapaipi amasungidwa m'malo owonekera. Chitoliro chakuda cha polyethence, chokhala ndi 2 mpaka 2.5% chogawanika bwino cha mpweya wakuda, chimatha kusungidwa bwino kunja kwa nyengo zambiri kwa zaka zambiri popanda kuwonongeka kwa ultra-violet exposure. Mitundu ina monga yoyera, yabuluu, yachikasu kapena ya lilac ilibe kukhazikika kofanana ndi kachitidwe ka mtundu wakuda ndipo nthawi yowonekera iyenera kukhala chaka chimodzi kuti katundu asungike bwino. othamanga kwambiri kuposa omwe ali mumdima wakuda

okhazikika PE mapaipi.Mapaipi achikuda awa osavomerezeka ntchito pamwamba pansi.

Mapaipi a polyethylene angagwiritsidwe ntchito pa kutentha kuyambira -50 ° C mpaka +60 ° C. Pakutentha kwambiri, kulimba kwamphamvu ndi kuuma kwa zinthu kumachepetsedwa Chifukwa chake, chonde onani chithunzi cha kutentha-kupanikizika. Kutentha kwapansi pa O°C kuyenera kuwonetseredwa kuti sing'angayo siimaundana, kupeŵa kuwonongeka kwa mapaipi.

Monga ma thermoplastics onse, PE ikuwonetsa kukulitsa kwamphamvu kwachitsulo. PE yathu ili ndi coefficent ya kukula kwa kutentha kwa 0.15 mpaka 0.20mm/m K, komwe kuli kokulirapo ka 1.5 kuposa mwachitsanzo. Zithunzi za PVC. Monga izi zimaganiziridwa panthawi yokonzekera kukhazikitsa sikuyenera kukhala ndi mavuto pankhaniyi.

Thermal conductivity ndi 0.38 W / m K. Chifukwa cha zomwe zimapangidwira zowonongeka, makina opangira mapaipi a PE amakhala okwera mtengo kwambiri poyerekeza ndi dongosolo lopangidwa ndi zinthu monga mkuwa.

Kuyaka Khalidwe

Polyethylene ndi ya mapulasitiki oyaka moto.Chiwerengero cha okosijeni chimakhala 17%.(Zinthu zomwe zimayaka ndi zosakwana 21% za mpweya wa mpweya mumlengalenga zimayesedwa kuti zimatha kuyaka).

PE imadontha ndikuwotcha popanda mwaye mutachotsa lawi. Kwenikweni, zinthu zapoizoni zimatulutsidwa ndi njira zonse zoyaka. Mpweya wa carbon monoxide nthawi zambiri umakhala woopsa kwambiri kwa anthu. PE ikayaka, makamaka mpweya woipa, carbon monoxide ndi madzi amapangidwa.

Kutentha kodziwotcha ndi 350 ℃ .

Zoyenera kuzimitsa moto ndi madzi, thovu, mpweya woipa kapena ufa.

Kukaniza Kwachilengedwe

Mapaipi a PE amatha kuwonongeka kuchokera kuzinthu zachilengedwe monga nyerere kapena makoswe. Kukana kuukira kumatsimikiziridwa ndi kuuma kwa PE yogwiritsidwa ntchito, geometry ya malo a PE, ndi mikhalidwe yoyika. M'mapaipi ang'onoang'ono ang'onoang'ono, zigawo zowonda za khoma zimatha kuonongeka ndi chiswe nthawi zambiri. Komabe kuwonongeka komwe kumachitika nthawi zambiri chifukwa cha chiswe ku PE kwapezeka kuti kumachitika chifukwa cha magwero ena a kuwonongeka kwamakina.

Makina a mapaipi a PE nthawi zambiri sakhudzidwa ndi zamoyo zakumtunda, komanso zam'madzi, ndipo mawonekedwe a parafini a paipi ya PE amalepheretsa kukula kwa grothes m'madzi.

Zida Zamagetsi

Chifukwa cha mayamwidwe otsika amadzi a PE, mphamvu zake zamagetsi sizimakhudzidwa ndi madzi mosalekeza.Popeza kuti PE ndi polima yopanda polar hydrocarbon polima, ndi insulator yodziwika bwino. , zotsatira za oxidizing media kapena nyengo. Kukana kwenikweni kwa voliyumu ndi> 1017 Ωcm; mphamvu ya dielectric ndi 220 kV/mm.

Chifukwa cha zotheka kukula kwa ma electrostic charges, kusamala kumalimbikitsidwa mukamagwiritsa ntchito PE pazantchito pomwe ngozi yamoto kapena kuphulika kwachitika.

CHANGRONGndi kampani yophatikizira yogawana ndi malonda, yomwe idakhazikitsidwa mu 2005 yomwe imayang'ana kwambiri kupanga mapaipi a HDPE, Zopangira & Mavavu, Mapaipi a PPR, Zopangira & Mavavu, PP compression fittings & Valves, komanso kugulitsa makina owotcherera a Plastic Pipe, Zida za Pipe, Pipe. Kukonza Clamp ndi zina zotero.
