Pakadali pano, zida zotchinjiriza chingwe zomwe zimagwiritsidwa ntchito popanga chingwe zimagawidwa m'magulu atatu: PE, PVC, ndi XLPE.Zotsatirazi zikuwonetsa kusiyana pakati pa zida zotetezera PE, PVC, ndi XLPE zomwe zimagwiritsidwa ntchito pazingwe.
Explanation wa gulu ndi makhalidwe a chingwe insulating zipangizo
PVC: Polyvinyl kolorayidi, polima wopangidwa ndi polymerization yaulere ya vinyl kolorayidi monomers pansi pamikhalidwe yapadera.Lili ndi makhalidwe okhazikika, kukana kwa asidi, kukana kwa alkali, kukana kwa dzimbiri, ndi kukana kukalamba, ndipo amagwiritsidwa ntchito kwambiri muzomangamanga, zofunikira za tsiku ndi tsiku, mapaipi ndi mapaipi, mawaya ndi zingwe, ndi zipangizo zosindikizira.Zimagawidwa mofewa ndi zolimba: zofewa zimagwiritsidwa ntchito makamaka popanga zipangizo zonyamula katundu, mafilimu aulimi, ndi zina zotero, ndipo zimagwiritsidwa ntchito kwambiri popanga zigawo za waya ndi chingwe, monga zingwe zamphamvu za polyvinyl chloride;pamene zolimba nthawi zambiri zimagwiritsidwa ntchito kupanga mapaipi ndi mbale.Mbali yaikulu ya polyvinyl chloride material ndi retardancy flame, choncho amagwiritsidwa ntchito kwambiri m'munda wopewa moto ndipo ndi imodzi mwa zipangizo zotetezera zomwe zimagwiritsidwa ntchito popanga mawaya ndi zingwe zosagwira moto.
PE: Polyethylene ndi utomoni wa thermoplastic wopangidwa ndi polymerization wa ethylene.Ndizopanda poizoni komanso zopanda vuto, zimakhala ndi kutentha kochepa kwambiri, ndipo zimatha kupirira kukokoloka kwa ma acid ambiri ndi alkalis, ndipo zimakhala ndi ntchito yabwino kwambiri yamagetsi.Panthawi imodzimodziyo, chifukwa polyethylene ali ndi makhalidwe omwe si polarity, ali ndi makhalidwe otsika kwambiri komanso otsika kwambiri, choncho amagwiritsidwa ntchito ngati chinthu chotchinjiriza kwa mawaya othamanga kwambiri ndi zingwe.
XLPE: Polyethylene yolumikizidwa ndi mtanda ndi mtundu wapamwamba wa zinthu za polyethylene pambuyo pa kusinthika.Pambuyo pakusintha, mawonekedwe ake akuthupi ndi mankhwala asinthidwa kwambiri poyerekeza ndi zinthu za PE, ndipo nthawi yomweyo, kukana kwake kutentha kwasinthidwa kwambiri.Chifukwa chake, mawaya ndi zingwe zopangidwa ndi zinthu zomangira za polyethylene zolumikizana ndi mtanda zili ndi zabwino zomwe mawaya amtundu wa polyethylene ndi zingwe sizingafanane: kulemera kopepuka, kukana kutentha kwabwino, kukana dzimbiri, kukana kwamphamvu kwambiri, ndi zina zambiri.
Poyerekeza ndi thermoplastic polyethylene, kutchinjiriza kwa XLPE kuli ndi zotsatirazi:
1 Kupititsa patsogolo kukana kwa kutentha kwa kutentha, kusinthika kwamakina pa kutentha kwakukulu, kupititsa patsogolo kukana kupsinjika kwa chilengedwe komanso kukana kukalamba kutentha.
2 Kukhazikika kwamphamvu kwamankhwala ndi kukana zosungunulira, kutsika kozizira kozizira, kumakhalabe ndi mphamvu zamagetsi zoyambira, kutentha kwanthawi yayitali kumatha kufika 125 ℃ ndi 150 ℃, mawaya opangidwa ndi polyethylene olumikizidwa ndi zingwe, komanso kupititsa patsogolo mphamvu yanthawi yayitali, Kutentha kwakanthawi kochepa kumatha kufika 250 ℃, makulidwe omwewo a mawaya ndi zingwe, olumikizidwa ndi polyethylene pano amanyamula mphamvu zambiri.
3 XLPE mawaya insulated mawaya ndi zingwe zabwino makina, madzi ndi ma radiation kukana katundu, kotero iwo ankagwiritsa ntchito.Monga: mawaya olumikizira mkati mwazida zamagetsi, zowongolera zamagalimoto, zowongolera zowunikira, mawaya owongolera ma siginecha agalimoto otsika, mawaya oyendetsa sitima, mawaya apansi panthaka ndi zingwe, zingwe zoteteza zachilengedwe, zingwe zam'madzi, zingwe zoyakira magetsi a nyukiliya, mawaya a TV apamwamba kwambiri. , X-RAY kuwombera mawaya othamanga kwambiri, mawaya otumizira magetsi ndi zingwe ndi mafakitale ena.
Kusiyana pakati pa zida zotchinjiriza chingwe PVC, PE, ndi XLPE
PVC: kutentha kwapang'onopang'ono, kukalamba kwaufupi, kukalamba pang'ono, kutulutsa pang'ono, kuchulukirachulukira, ndi utsi waukulu ndi ngozi zamafuta a asidi pakayaka moto.Zogulitsa zonse mumakampani amawaya ndi zingwe, katundu wabwino wamakina ndi makina, magwiridwe antchito abwino, otsika mtengo komanso mtengo wogulitsa.Koma ili ndi ma halojeni, ndipo kugwiritsa ntchito sheath ndikokulirapo.
PE: Zamagetsi zabwino kwambiri, ndi zabwino zonse za PVC zomwe tazitchula pamwambapa.Amagwiritsidwa ntchito kwambiri pakutchinjiriza waya kapena chingwe, kutchinjiriza kwa mzere wa data, kutsika kwa dielectric pafupipafupi, koyenera mizere ya data, mizere yolumikizirana, ndi kutsekereza kwama waya osiyanasiyana apakompyuta.
XLPE: Pafupifupi bwino ngati PE muzinthu zamagetsi, pomwe kutentha kwanthawi yayitali kumakhala kokulirapo kuposa PE, zida zamakina ndizabwino kuposa PE, ndipo kukana kukalamba kuli bwino.Mtundu watsopano wazinthu zachilengedwe zokhala ndi kukana kutentha kwambiri komanso kukana zachilengedwe, pulasitiki ya thermosetting.Nthawi zambiri amagwiritsidwa ntchito mu mawaya apakompyuta ndi malo omwe ali ndi zofunikira zotsutsana ndi chilengedwe.
Kusiyana pakati pa XLPO ndi XLPE
XLPO (polyolefin yolumikizidwa pamtanda): EVA, utsi wochepa komanso wopanda halogen, wolumikizidwa ndi ma radiation olumikizana kapena olumikizidwa ndi mphira wa olefin polima.Mawu ambiri a gulu la ma resins a thermoplastic omwe amapezeka ndi polymerizing kapena copolymerizing α-olefins monga ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene, ndi ma cycloolefins ena. .
XLPE (polyethylene yolumikizidwa pamtanda): XLPE, polyethylene yolumikizidwa, silane yolumikizirana kapena kulumikizana ndi mankhwala, ndi utomoni wa thermoplastic wopangidwa ndi polymerization ya ethylene.M'makampani, amaphatikizanso ma copolymers a ethylene ndi pang'ono α-olefins.
