Ukuba bhetyebhetye

Ukuguquguquka kombhobho we-polyethylene kuvumela ukuba ugobe ngaphezulu, ngaphantsi, kwaye ujikeleze imiqobo kunye nokwenza ukuphakama kunye neenguqu zecala.Kwezinye iimeko, ukuguquguquka kombhobho kunokuphelisa ngokuphawulekayo ukusetyenziswa kwezixhobo kunye nokunciphisa kakhulu iindleko zokufakela.

Umbhobho we-CHHUANGRONG PE unokugotywa ukuya kubuncinci beradiyasi phakathi kwama-20 ukuya kwangama-40 ububanzi bombhobho, oxhomekeke ikakhulu kwi-SDR yombhobho othile.

Ubunzima obuKhanya

Izinto ozilindile emhlabane

Ubuninzi bezinto ze-PE yi-1/7 kuphela yentsimbi. Ubunzima bombhobho we-PE bungaphantsi kakhulu kunobo bentsimbi ekhonkrithiweyo, okanye umbhobho wentsimbi. Inkqubo yemibhobho ye-PE kulula ukuyiphatha kunye nokuyifaka, kwaye ukucuthwa kwamandla omntu kunye neemfuno zezixhobo kunokubangela ukongiwa kofakelo.

Isiseko se-hydrostatic yoyilo lombhobho we-CHUANGRONG isekelwe kwidatha yovavanyo olubanzi lwe-hydrostatic evandlakanywe ngeendlela ezisemgangathweni zoshishino.Ukuziphatha kwexesha elide lokumelana noxinzelelo lwangaphakathi olunikezelwa yi-curve yamandla e-hydrostatic esekelwe kwi-EN ISO 15494 standard (jonga icandelo X). Imida yokusetyenziswa kwemibhobho kunye nokufakelwa, njengoko kubonisiwe kwidayagram yoxinzelelo lobushushu, inokufumaneka kula magophe, abonisa ukuba umbhobho unobomi obulindelekileyo malunga neminyaka engama-50 xa uhambisa amanzi kwi-20℃. Iimeko zangaphakathi nezangaphandle zokusingqongileyo zinokubutshintsha ubomi obulindelekileyo okanye zitshintshe isiseko soyilo esicetyiswayo kwisicelo esinikiweyo.

Ukumelana neMozulu

Iipropati zoThermal

Imozulu yeeplastiki yenzeke ngenkqubo yokuthotywa komphezulu, okanye i-oxidation, ngenxa yempembelelo edibeneyo yemitha ye-ultra violet, ukunyuka kwamaqondo obushushu, kunye nokufuma xa imibhobho igcinwe kwiindawo ezivulekileyo. Umbhobho wepolyethylensi emnyama, equlathe i-2 ukuya kwi-2.5% eyahlulwe ngokucokisekileyo ikhabhoni emnyama, inokugcinwa ngokukhuselekileyo ngaphandle kwiindawo ezininzi zemozulu iminyaka emininzi ngaphandle komonakalo wokuvezwa kwi-ultra-violet. Eminye imibala efana nemhlophe, ibhlowu, etyheli okanye i-lilac ayinazinzo olufanayo kunye neenkqubo ezinemibala emnyama kwaye ixesha lokuvezwa kufuneka likhawulelwe kunyaka omnye wogcino lweempawu. umlinganiselo okhawulezayo kunezo zimnyama kwikhabhoni

imibhobho ye-PE ezinzile.Le mibhobho enemibala ayikhuthazwa kwizicelo ezingaphezulu komhlaba.

Imibhobho yePolyethylene ingasetyenziswa kumaqondo obushushu ukusuka-50°C ukuya +60°C. Kwiqondo lokushisa eliphezulu, amandla okuqina kunye nokuqina kwezinto eziphathekayo ziyancipha Ngoko ke, nceda uqhagamshelane nomzobo woxinzelelo lobushushu. Kumaqondo obushushu angaphantsi kwe-O°Cit kufuneka kuqinisekiswe ukuba indawo ephakathi ayikhenkcezi, ukuthintela ukonakala kombhobho ngenxa yoko.

Njengazo zonke i-thermoplastics, i-PE ibonisa ukwanda kwe-thermal ephezulu yesinyithi. I-PE yethu ine-coefficent yokwandiswa kwe-thermal yomgca we-0.15 ukuya kwi-0.20mm / m K, eyi-1.5 ngamaxesha amakhulu kunomz. I-PVC . Njengoko oku kuthathelwa ingqalelo ngexesha lokucwangciswa kofakelo akufuneki kubekho iingxaki kulo mba.

I-thermal conductivity yi-0.38 W / m K. Ngenxa yeempawu ze-insulation ezibangelwayo, inkqubo yepayipi ye-PE ibaluleke kakhulu kunoqoqosho xa kuthelekiswa nenkqubo eyenziwe ngezinto ezifana nobhedu.

Ukuvutha kokuziphatha

I-Polyethylene yeyeeplastiki ezinokutsha.Isalathisi se-oksijini sifikelela kwi-17%.(Izinto ezivuthayo ngaphantsi kwe-21% ye-oksijini emoyeni zibhekwa njengento enokutsha).

I-PE ithontsiza kunye ne-coninues ukutshisa ngaphandle kwe-soot emva kokususa ilangatye. Ngokusisiseko, izinto ezinobuthi zikhutshwa zizo zonke iinkqubo ezivuthayo. Ikharbhon monoxide yeyona mveliso yokutsha iyingozi kakhulu ebantwini. Xa i-PE itshisa, ikakhulu i-carbon dioxide, i-carbon monoxide kunye namanzi ayakhiwa.

Ubushushu bokuzitshisa bungama-350℃.

Iiarhente ezifanelekileyo zokulwa nomlilo ngamanzi, ugwebu, ikharbon diokside okanye umgubo.

Ukunyangwa kwebhayoloji

Imibhobho ye-PE inokuba phantsi komonakalo kwimithombo yebhayoloji efana neembovane okanye iimpuku. Ukuchasana nokuhlaselwa kunqunywe ngobunzima be-PE esetyenzisiweyo, ijometri yeendawo ze-PE, kunye neemeko zofakelo. Kwimibhobho edayamitha emincinci, amacandelo eludongeni olucekethekileyo angonakaliswa ziintubi kwiimeko ezinzima. Nangona kunjalo umonakalo odla ngokubalelwa kuhlaselo lweentubi kwi-PE emva koko ufunyenwe ngenxa yeminye imithombo yomonakalo womatshini.

Iinkqubo zemibhobho ye-PE azichatshazelwanga zizinto zebhayoloji kubini emhlabeni, nakwizinto zaselwandle, kwaye ubume beparafini kumbhobho we-PE budodobalisa ukwakhiwa kweegrothe zaselwandle ezisebenza.

Iipropati zoMbane

Ngenxa yokufunxwa kwamanzi aphantsi kwe-PE, iipropati zayo zombane azichatshazelwa nzima kuqhagamshelwano oluqhubekayo lwamanzi.Njengoko i-PE i-polar hydrocarbon polymer engabonakaliyo, i-insulator ebalaseleyo. , iziphumo zemidiya ye-oxidizing okanye imozulu. Ukuxhathisa umthamo othile ngu>1017 Ωcm; amandla edielectric yi-220 kV/mm.

Ngenxa yophuhliso olunokwenzeka lweentlawulo ze-electrostic, isilumkiso siyacetyiswa xa usebenzisa i-PE kwizicelo apho ingozi yomlilo okanye ugqabhuko-dubulo lubonakaliswa.

CHUANGRONGlishishini lesabelo kunye nenkampani yorhwebo edibeneyo, eyasekwa kwi-2005 egxile kwimveliso yeMibhobho ye-HDPE, iFittings & Valves, i-PPR Pipes, iFittings & Valves, i-PP compression fittings & Valves, kunye nokuthengiswa koomatshini bePlastiki yePlastiki yokuWelding, izixhobo zePipe, iPipe. I-Clamp yokulungisa njalo njalo.
