1.PE chitoliro dzimbiri kukana makhalidwe?
Polyethylene ndi zinthu zopanda pake zomwe zimatha kupirira dzimbiri zama media osiyanasiyana.Palibe dzimbiri electrochemical, palibe odana ndi dzimbiri wosanjikiza.
2. Makhalidwe osatulutsa a PE chubu?
Chitoliro cha polyethylenemakamaka utenga kuwotcherera kugwirizana (kulumikizana otentha maphatikizidwe kapena maphatikizidwe magetsi maphatikizidwe), amene makamaka amaonetsetsa chizindikiritso cha zinthu mawonekedwe, kapangidwe ndi chitoliro thupi, ndipo amazindikira kusakanikirana olowa ndi chitoliro.Kuyesera kumatsimikizira kuti kulimba kwamphamvu ndi kuphulika kwamphamvu kwa mawonekedwe ndi apamwamba kuposa thupi la chitoliro, ndipo palibe vuto lotayikira poyerekeza ndi mfundo za mphira kapena mfundo zina zamakina.
3.PE chitoliro mkulu kulimba makhalidwe?
Chitoliro cha polyethylene ndi mtundu wa chitoliro cholimba kwambiri, elongation yake yopuma nthawi zambiri imakhala yoposa 500%, luso lotha kusintha kukhazikika kwa chitoliro champhamvu kwambiri.Ndi mtundu wa chitoliro chomwe chili ndi ntchito zabwino kwambiri zotsutsana ndi seismic.Mu 1995 chivomezi cha Kobe ku Japan, chitoliro cha gasi cha polyethylene ndi chitoliro chamadzi ndi chitoliro chopulumutsira.Choncho, Japan pambuyo chivomezi mwamphamvu kulimbikitsa ntchito Pe chitoliro m'munda mpweya.
4.PE chubu ali ndi makhalidwe abwino kusinthasintha?
Kusinthasintha kwa polyethylene kumapangitsa kuti mapaipi a polyethylene abwezeretsedwe ndikuperekedwa kwautali wautali popanda kufunikira kophatikizana kosiyanasiyana.Kumanga kwa trenchless, mayendedwe a chitoliro cha polyethylene angasinthidwe mosavuta malinga ndi zofunikira za njira yomanga, ndipo kukula koyambirira ndi kukula kwake kumatha kubwezeretsedwa pambuyo pomanga.
5. Kodi mungamvetse bwanji mawonekedwe a chubu cha PE chokhala ndi kukana bwino kukwapula?
Zikwapu zimayambitsa kupsinjika maganizo muzinthu, zomwe zimayambitsa kulephera kwa chitoliro.Ukadaulo wopanda trenchless ukagwiritsidwa ntchito, zokopa zimakhala zovuta kuzipewa, kaya chitoliro chatsopano chayikidwa kapena chitoliro chakale chimasinthidwa.M'zaka zaposachedwa, zatsimikiziridwa kuti PE80 kalasi polyethylene chitoliro ali kukana bwino kuchepetsa mng'alu kukula ndi zikande kukana, ndi PE100 polyethylene chitoliro ali bwino zikande kukana.Chifukwa chake, chitoliro cha polyethylene chimagwiritsidwa ntchito kwambiri pomanga ukadaulo wopanda trenchless.
6. PE chitoliro ali ndi makhalidwe abwino mofulumira mng'alu kufala kukana.
Kusweka kofulumira kwa mapaipi ndi mtundu wangozi wangozi.Mng’aluyo umakula mofulumira pa liŵiro linalake, kuchititsa kuphulika kwa mapaipi makumi a mamita kapena ngakhale zikwi zikwi za mamita a mapaipi nthawi yomweyo, ndipo zotsatira zake zimakhala zoopsa.Kumayambiriro kwa zaka za m’ma 1950, panali ngozi zingapo zong’ambika mofulumira mu chitoliro cha gasi cha United States.Kuphulika kofulumira kwa chitoliro cha gasi cha polyethylene sikunapezeke pochita.M'zaka zaposachedwa, kafukufuku wambiri wachitika pa kung'ambika kofulumira kwa chitoliro padziko lapansi.Zotsatira zikuwonetsa kuti kukana kwa chitoliro cha polyethylene kufalitsa kusweka ndi chimodzi mwazabwino kwambiri.
