Polyethylene yolumikizidwa ndi mtandakutchinjiriza amapangidwa ndi mankhwala kapena njira zakuthupi kusintha polyethylene molekyulu kuchokera liniya maselo mapangidwe atatu azithunzithunzi maukonde dongosolo, kuchokera thermoplastic zakuthupi thermosetting zakuthupi, ndi kuonjezera kutentha ntchito 70 ℃ mpaka 90 ℃, amene kwambiri bwino zinthu ntchito. .
Polyethylene yolumikizidwa ndi mtandaili ndi zabwino zotsatirazi.
1, ntchito yosagwira kutentha;XLPE yokhala ndi mauna atatu-dimensional mesh ili ndi ntchito yabwino kwambiri yosamva kutentha.Sizidzaphwanyidwa ndikuyika mpweya pansi pa 200 ° C.
Kutentha kwa nthawi yayitali kumatha kufika 90 ℃, ndipo moyo wamafuta ukhoza kufika zaka 40.
2, Insulation performance: XLPE imasunga mikhalidwe yabwino yotchinjiriza ya PE, ndipo kukana kwa kutchinjiriza kumachulukitsidwa.Dielectric yake
Dielectric loss angle tangent mtengo ndi yaying'ono kwambiri, ndipo samakhudzidwa kwambiri ndi kutentha.
3, Mawotchi katundu: Chifukwa kukhazikitsidwa kwa zomangira zatsopano mankhwala pakati macromolecules, kuuma, stiffness, kuvala kukana ndi kukana mphamvu ya XLPE ndi bwino.
Kuuma, kuuma, kukana kwa abrasion ndi kukana kwa XLPE kumakhala bwino chifukwa cha kukhazikitsidwa kwa zomangira zatsopano zamakina pakati pa ma macromolecules, motero kubwezera zophophonya za PE zomwe zimasweka mosavuta ndi kupsinjika kwa chilengedwe.
4, Chemical kukana: XLPE ali amphamvu asidi ndi alkali kukana ndi kukana mafuta, ndi zinthu kuyaka ake makamaka madzi ndi mpweya woipa.
Ndizosavulaza zachilengedwe ndipo zimakwaniritsa zofunikira zachitetezo chamakono chamoto.
