He aha ka ʻokoʻa ma waena o nā mea hoʻokaʻawale kelepona PE, PVC, a me XLPE?

I kēia manawa, hoʻokaʻawale ʻia nā mea insulation cable i hoʻohana ʻia i ka hana kelepona i ʻekolu mau ʻāpana: PE, PVC, a me XLPE.Hōʻike ka mea aʻe i nā ʻokoʻa ma waena o nā mea insulating PE, PVC, a me XLPE i hoʻohana ʻia i nā kaula.

Explanation o ka hoʻokaʻawale ʻana a me nā ʻano o nā mea insulating cable

PVC: Polyvinyl chloride, he polymer i hana ʻia e ka polymerization manuahi o nā monomers vinyl chloride ma lalo o nā kūlana kikoʻī.Loaʻa iā ia nā hiʻohiʻona o ke kūpaʻa, ke kūpaʻa waikawa, ke kūpaʻa alkali, ka pale ʻana i ka corrosion, a me ke kūpaʻa ʻelemakule, a hoʻohana nui ʻia i nā mea kūkulu hale, nā mea e pono ai i kēlā me kēia lā, nā paipu a me nā paipu, nā uwea a me nā kaula, a me nā mea hoʻopaʻa.Hoʻokaʻawale ʻia ia i ka palupalu a me ka paʻakikī: hoʻohana nui ʻia nā mea palupalu e hana i nā mea hoʻopihapiha, nā kiʻiʻoniʻoni mahiʻai, a me nā mea ʻē aʻe, a hoʻohana nui ʻia i ka hana ʻana i nā uea a me nā ʻāpana insulation cable, e like me nā polyvinyl chloride insulated power cables;ʻoiai ua hoʻohana mau ʻia nā mea paʻakikī e hana i nā paipu a me nā papa.ʻO ka hiʻohiʻona nui loa o ka polyvinyl chloride material he flame retardancy, no laila ua hoʻohana nui ʻia i ke kahua o ka pale ahi a ʻo ia kekahi o nā mea insulating maʻamau i hoʻohana ʻia no ka lapalapa ahi a me ke ahi-pale a me nā kaula.

PE: ʻO ka polyethylene kahi resin thermoplastic i hana ʻia e ka polymerization o ka ethylene.ʻAʻole ia he mea ʻawaʻawa a maikaʻi ʻole, he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa maikaʻi loa, a hiki ke kūpaʻa i ka erosion o ka hapa nui o nā waikawa a me nā alkalis, a he maikaʻi loa ka hana insulation uila.I ka manawa like, no ka mea he polyethylene nā hiʻohiʻona o ka non-polarity, loaʻa iā ia nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa a me ka conductivity kiʻekiʻe, no laila e hoʻohana mau ʻia ia ma ke ʻano he mea insulation no nā uea kiʻekiʻe-voltage a me nā kaula.

XLPE: ʻO ka polyethylene i hoʻopili ʻia ke ʻano he ʻano kiʻekiʻe o ka mea polyethylene ma hope o ka hoʻololi ʻana.Ma hope o ka hoʻomaikaʻi ʻana, ua hoʻomaikaʻi maikaʻi ʻia kona mau kino kino a me nā mea kemika i hoʻohālikelike ʻia me ka mea PE, a i ka manawa like, ua hoʻomaikaʻi nui ʻia kona pae pale wela.No laila, ʻo nā uea a me nā kaula i hana ʻia me ka polyethylene insulation material i hoʻopili ʻia he mau mea maikaʻi ʻaʻole hiki ke hoʻohālikelike ʻia nā uea a me nā uwea polyethylene insulation: ke kaumaha māmā, ke kūpaʻa wela maikaʻi, ke kū ʻana o ka corrosion, ke kūpaʻa insulation nui, etc.

Ke hoʻohālikelike ʻia me ka polyethylene thermoplastic, XLPE insulation he mau pono kēia:

1 Hoʻomaikaʻi i ka pale ʻana i ka wela, hoʻomaikaʻi i nā waiwai mechanical i ka wela kiʻekiʻe, hoʻomaikaʻi i ke koʻikoʻi o ke kaiapuni i ke kū ʻana a me ka pale ʻana i ka wā kahiko.

2 Hoʻonui i ka paʻa kemika a me ka pale pale, hoʻemi i ke kahe anuanu, mālama pono i nā waiwai uila, hiki i ka mahana hana lōʻihi ke hiki i 125 ℃ a me 150 ℃, nā kaula polyethylene insulated cross-linked a me nā kaula, hoʻomaikaʻi ʻia hoʻi i ka hiki ke halihali pōkole, kona Hiki ke piʻi ka mahana wela o ka wā pōkole i 250 ℃, ka mānoanoa like o nā uea a me nā kaula, ʻoi aku ka nui o ka hiki ke halihali i ka polyethylene i kēia manawa.

3 XLPE insulated uwea a me ka uwea i maikai mechanical, wai a me ka radiation ku'eku'e waiwai, no laila, ua hoohana nui ia.E like me: nā uwea pili i loko o nā mea uila, nā alakaʻi kaʻa, nā alakaʻi kukui, nā kaʻa kaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa hoʻomalu uea, nā locomotive uea, subway uwea a me nā uwea, mining kaiapuni pale uwea, moana uwea, nukelea kau kau uwea, TV high-voltage uwea , X-RAY e puhi ana i na uwea uwea ki'eki'e, a me na uwea lawe mana a me na uwea a me na oihana e ae.

ʻO nā ʻokoʻa ma waena o nā mea hoʻokaʻawale kelepona PVC, PE, a me XLPE

PVC: haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, pōkole ke ola ʻelemakule wela, hiki ke hoʻouna liʻiliʻi, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, a me ka nui o ka uahi a me nā pōʻino kinoea i ke ahi.ʻO nā huahana maʻamau i ka uea a me ka ʻoihana kelepona, nā waiwai kino a me nā mīkini maikaʻi, nā hana hoʻoponopono maikaʻi, nā kumu kūʻai haʻahaʻa a me ke kumu kūʻai.Akā aia nā halogens, a ʻo ka hoʻohana ʻana i ka pū ka mea nui loa.

PE: ʻO nā waiwai uila maikaʻi loa, me nā pono āpau o PVC i ʻōlelo ʻia ma luna.Hoʻohana maʻamau ʻia i ka uea a i ʻole ka hoʻokaʻawale ʻana i ke kaula, ka hoʻokaʻawale ʻana i ka laina ʻikepili, ka haʻahaʻa dielectric mau, kūpono no nā laina ʻikepili, nā laina kamaʻilio, a me nā ʻano ʻokoʻa ʻokoʻa o ka computer peripheral wire core insulation.

XLPE: Kokoke e like me ka PE i nā waiwai uila, ʻoiai ʻoi aku ka kiʻekiʻe o ka mahana hana lōʻihi ma mua o PE, ʻoi aku ka maikaʻi o nā waiwai mechanical ma mua o PE, a ʻoi aku ka maikaʻi o ke kūpaʻa ʻelemakule.He ʻano hou o nā huahana pili i ke kaiapuni me ke kūpaʻa kiʻekiʻe kiʻekiʻe maikaʻi a me ke kūpaʻa kūlohelohe, kahi plastic thermosetting.Hoʻohana maʻamau i nā uwea uila a me nā wahi me nā koi kūʻē kūlohelohe kiʻekiʻe.

ʻO ka ʻokoʻa ma waena o XLPO a me XLPE

XLPO (polyolefin pili kea): EVA, uahi haʻahaʻa a me ka halogen-ʻole, hoʻoheheʻe ʻia a i ʻole polimer olefin i hoʻopaʻa ʻia.He huaʻōlelo maʻamau no kahi papa o nā resins thermoplastic i loaʻa ma ka polymerizing a i ʻole copolymerizing α-olefins e like me ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene, a me kekahi mau cycloolefins. .

XLPE (polyethylene i hoʻohui ʻia): XLPE, polyethylene i hoʻopaʻa ʻia, silane cross-linking a i ʻole ka hoʻopili kemika, he resin thermoplastic i hana ʻia e ka polymerization o ka ethylene.Ma ka ʻoihana, loaʻa pū kekahi copolymers o ka ethylene a me kahi liʻiliʻi o nā α-olefins.
