Polyethylene pili keaHana ʻia ka insulation e ke kemika a i ʻole ke ʻano kino e hoʻololi i ka mole polyethylene mai ka linear molecular structure i ʻekolu-dimensional network structure, mai ka thermoplastic material a thermosetting material, a e hoʻonui i ka mahana hana mai 70 ℃ a 90 ℃, kahi e hoʻomaikaʻi nui ai i ka hana waiwai. .
Polyethylene pili keaLoaʻa iā ia nā pōmaikaʻi.
1、Hoʻokō wela-pale;ʻO XLPE me ʻekolu-dimension mesh structure he maikaʻi loa ka hana pale wela.ʻAʻole ia e hoʻoheheʻe a carbonize ma lalo o 200 ° C.
Hiki i ka mahana hana lōʻihi ke hiki i 90 ℃, a hiki i ke ola wela ke hiki i 40 mau makahiki.
2、Ka hana insulation: Mālama ʻo XLPE i nā hiʻohiʻona insulation maikaʻi mua o PE, a hoʻonui hou ʻia ke kūpaʻa insulation.ʻO kāna dielectric
He liʻiliʻi loa ka waiwai dielectric loss angle tangent, a ʻaʻole pili nui ʻia e ka wela.
3、 Nā waiwai mīkini: Ma muli o ka hoʻokumu ʻana i nā paʻa kemika hou ma waena o nā macromolecules, ʻoi aku ka paʻakikī, ka ʻoʻoleʻa, ke kūpaʻa a me ka hopena o ka XLPE.
Ua hoʻomaikaʻi ʻia ka paʻakikī, ka ʻoʻoleʻa, ka pale abrasion a me ka hopena o ka XLPE ma muli o ka hoʻokumu ʻana i nā mea paʻa kemika hou ma waena o nā macromolecules, no laila e uku ai i nā hemahema o ka PE i maʻalahi i ke koʻikoʻi o ke kaiapuni.
4、 Ke kū'ē kemika: Loaʻa i ka XLPE ka waikawa ikaika a me ke kūpaʻa alkali a me ka pale ʻana i ka aila, a ʻo kāna huahana hoʻopau he wai a me carbon dioxide.
He mea liʻiliʻi ka pōʻino i ke kaiapuni a hoʻokō i nā koi o ka palekana ahi hou.
