Ukuguquguquka
Ukuguquguquka kombhobho we-polyethylene kuvumela ukuba ugobe ngaphezulu, ngaphantsi, nangaphandle kwemiqobo kunye nokwenza utshintsho lokuphakama kunye nolwalathiso.Kwezinye iimeko, ukuguquguquka kombhobho kunokunciphisa kakhulu ukusetyenziswa kwezinto zokufakelwa kwaye kunciphise kakhulu iindleko zokufakela.
Umbhobho we-CHUANGRONG PE unokugotywa ube yi-radius encinci phakathi kwamaxesha angama-20 ukuya kwangama-40 ubukhulu bombhobho, nto leyo exhomekeke kakhulu kwi-SDR yombhobho othile.

Ubunzima obuKhanyayo
Izinto ozilindile emhlabane
Ubunzima bezinto ze-PE yi-1/7 kuphela yobo bentsimbi. Ubunzima bepayipi ye-PE buncinci kakhulu kunobo besinyithi esenziwe ngekhonkrithi, okanye ipayipi yentsimbi. Inkqubo yepayipi ye-PE kulula ukuyiphatha nokuyifakela, kwaye ukuncipha kwamandla omntu kunye neemfuno zezixhobo kunokubangela ukonga kokufakwa.
Isiseko soyilo lwe-hydrostatic lombhobho we-CHUANGRONG sisekelwe kwidatha ebanzi yovavanyo lwe-hydrostatic evavanywe ngeendlela ezisemgangathweni zoshishino. Ukuziphatha kwexesha elide kokumelana noxinzelelo lwangaphakathi olubonelelwa yi-hydrostatic strength curve ngokusekelwe kumgangatho we-EN ISO 15494 (jonga icandelo X). Imida yokusetyenziswa kwemibhobho kunye nezixhobo, njengoko kuboniswe kumzobo woxinzelelo-ubushushu, inokufumaneka kwezi curves, ezibonisa ukuba umbhobho unobomi obumalunga neminyaka engama-50 xa uthutha amanzi kwi-20℃. Iimeko zokusingqongileyo zangaphakathi nezangaphandle zinokutshintsha ubomi obulindelweyo okanye zitshintshe isiseko soyilo esicetyiswayo sesicelo esithile.
Ukumelana nemozulu
Iipropati zoBushushu
Ukuguguleka kweplastiki kwenzeka ngenkqubo yokuwohloka komphezulu, okanye i-oxidation, ngenxa yesiphumo esidibeneyo semitha ye-ultra violet, ubushushu obandayo, kunye nokufuma xa imibhobho igcinwa kwiindawo ezivezwe. Umbhobho omnyama we-polyethlence, oqulethe i-2 ukuya kwi-2.5% yekhabhoni emnyama eyahlulwe kakuhle, unokugcinwa ngokukhuselekileyo ngaphandle kwiindawo ezininzi zemozulu iminyaka emininzi ngaphandle komonakalo ovela kwi-ultra-violet exposure. Umnyama wekhabhoni sesona songezo sisebenzayo sokuphucula iimpawu zemozulu yezinto zeplastiki. Eminye imibala efana nomhlophe, luhlaza okwesibhakabhaka, tyheli okanye lilac ayinayo uzinzo olufanayo neenkqubo ezimnyama ezinombala kwaye ixesha lokuvezwa kufuneka lilinganiselwe kunyaka omnye ukuze kugcinwe iipropati ezifanelekileyo. Ngezi nkqubo zemibala, iileya ze-oxidation yomphezulu wangaphandle zikhula ngesantya esiphezulu kunezo zikwikhabhoni emnyama.
iipayipi ze-PE ezizinzileyo. Ezi payipi ezinemibala azikhuthazwa ukusetyenziswa ngaphezulu komhlaba.
Iipayipi zePolyethylene zingasetyenziswa kumaqondo obushushu aqala kwi-50°C ukuya kwi-+60°C. Kumaqondo obushushu aphezulu, amandla okuxinana kunye nokuqina kwezinto kuyancitshiswa. Ngoko ke, nceda ujonge umzobo wobushushu boxinzelelo. Kumaqondo obushushu angaphantsi kwe-O°C, kufuneka kuqinisekiswe ukuba i-medium ayikhenkcezi, ukuze kuthintelwe umonakalo kwinkqubo yepayipi.
Njengazo zonke ii-thermoplastics, i-PE ibonisa ukwanda okuphezulu kobushushu kunesinyithi. I-PE yethu inomlinganiselo wokwanda kobushushu obuhamba ngomgca we-0.15 ukuya kwi-0.20mm/m K, ophindwe kayi-1.5 kune-PVC. Njengoko oku kuthathelwa ingqalelo ngexesha lokucwangciswa kofakelo akufuneki kubekho ngxaki kulo mba.
Ukuqhuba kobushushu yi-0.38 W/m K. Ngenxa yeempawu zokugquma ezibangelwa kokugquma, inkqubo yepayipi ye-PE ingabizi kakhulu xa ithelekiswa nenkqubo eyenziwe ngezinto ezifana nobhedu.
Indlela Yokuziphatha Ngokutsha

I-Polyethylene yeyeplastiki etshayo. Isalathisi se-oksijini sifikelela kwi-17%. (Izinto ezitshayo ezine-oxygen engaphantsi kwe-21% emoyeni zithathwa njengezitshayo).
I-PE ivuza ize iqhubeke nokutsha ngaphandle kokulahla inkunkuma emva kokususa ilangatye. Ngokusisiseko, izinto ezinobuthi zikhutshwa zizo zonke iinkqubo zokutsha. I-Carbon monoxide ngokubanzi yeyona nto iyingozi kakhulu ebantwini. Xa i-PE itsha, ngokuyintloko i-carbon dioxide, i-carbon monoxide kunye namanzi kwakheka.
Ubushushu bokuzitshisa buyi-350℃.
Izinto ezifanelekileyo zokulwa nomlilo ngamanzi, igwebu, ikharbon diokside okanye umgubo.
Ukumelana Nezinto Eziphilayo
Iipayipi ze-PE zinokonakala ngenxa yemithombo yezinto eziphilayo ezifana neembovane okanye iimpuku. Ukumelana nohlaselo kuxhomekeka kubunzima be-PE esetyenzisiweyo, ijiyometri yeendawo ze-PE, kunye neemeko zokufakelwa. Kwiipayipi ezincinci ezinobubanzi, iindawo ezincinci zodonga zinokonakala ngenxa yeentubi kwiimeko ezigqithisileyo. Nangona kunjalo, umonakalo odla ngokubangelwa kukuhlaselwa kweentubi kwi-PE ufunyenwe kamva ngenxa yeminye imithombo yomonakalo woomatshini.
Iinkqubo zemibhobho ye-PE ngokubanzi azichaphazeleki zizinto eziphilayo emhlabeni, nakwiindawo zaselwandle, kwaye i-paraffinic yemibhobho ye-PE ithintela ukwakheka kwemibhobho yaselwandle esebenza.
Iipropati zoMbane
Ngenxa yokufunxwa kwamanzi okuncinci kwe-PE, iipropati zayo zombane azichaphazeleki kakhulu kukudibana kwamanzi rhoqo. Ekubeni i-PE iyi-polymer ye-hydrocarbon engeyiyo i-polar, sisivikelo esibalaseleyo. Nangona kunjalo, ezi mpawu zinokuba mandundu kakhulu ngenxa yongcoliseko, iziphumo ze-oxidizing media okanye i-weathering. Ukumelana nomthamo othile yi>1017 Ωcm; amandla e-dielectric yi-220 kV/mm.
Ngenxa yophuhliso olunokwenzeka lwee-electrostic charges, kuyacetyiswa ukuba uqaphele xa usebenzisa i-PE kwiindawo apho kukho ingozi yomlilo okanye ukuqhuma.
