I loko o nā kaula mana voltage waena a me ke kiʻekiʻe, he kuleana koʻikoʻi nā hui pale semi-conductive i ka hōʻoia ʻana i ka hoʻolaha like ʻana o ke kahua uila a me ka hoʻomaikaʻi ʻana i ka pilina ma waena o ke alakaʻi, ka insulation, a me nā papa pale. Hoʻopili pinepine ʻia kēia mau hui me kahi resin kumu, ka ʻeleʻele kalapona conductive, a me nā mea hoʻohui hana like ʻole. Ma waena o kēia mau ʻāpana, he mana koʻikoʻi ko ka resin kumu i ka hiki ke hana, ke kūpaʻa uila, ka hoʻohālikelike interface, ka hana ʻelemakule thermal, a me ka hilinaʻi lōʻihi o ke kaula.
I nā makahiki i hala iho nei, ua lilo ʻo Ethylene Butyl Acrylate (EBA) i hoʻokahi o nā resins kumu i makemake ʻia no nā hui pale semi-conductive i hoʻohana ʻia i nā kaula uila waena a me ke kiʻekiʻe, mahalo i kāna hana holoʻokoʻa kaulike maikaʻi.
He aha ka EBA Resin?
ʻO EBA (Ethylene Butyl Acrylate) kahi copolymer thermoplastic i hana ʻia mai ka ethylene a me ka butyl acrylate (BA). ʻO ka hoʻokomo ʻana o nā hui butyl acrylate i loko o ke kaulahao polymer e hāʻawi i ka polarity kūpono, e ʻae ana iā EBA e hoʻohui i nā ʻano hana maikaʻi loa o nā polyolefins me ka hoʻomaikaʻi ʻana i ka hoʻohālikelike me nā mea polar.
Ke hoʻohālikelike ʻia me ka polyethylene maʻamau, hāʻawi ʻo EBA i kekahi mau pono:
Ka maʻalahi maikaʻi loa a me ka paʻakikī haʻahaʻa haʻahaʻa
ʻO ke kūpaʻa wela maikaʻi a me ke kū'ē ʻana i ka ʻelemakule wela
Hoʻomaikaʻi ʻia ka hoʻopuehu ʻana o ka ʻeleʻele kalapona alakaʻi
Hoʻohui maikaʻi ʻia me ka polyethylene,XLPE, a me nā mea hoʻomehana ʻē aʻe
ʻO kēia mau ʻano e hoʻolilo iā EBA i resin kumu hoihoi no nā hui pale semi-conductive.
No ke aha i kūpono ai ʻo EBA no nā hui pale semi-conductive?
Hoʻomaikaʻi ʻia ka hoʻopuehu ʻeleʻele kalapona
ʻO ka hana uila o kahi hui pale semi-conductive e hilinaʻi nui ʻia i ka hiki i ka conductive carbon black ke hana i kahi pūnaewele conductive like a hoʻomau.
Hoʻoikaika nā hui polar ma EBA i ka pilina ma waena o ka resin a me ke kalapona ʻeleʻele conductive, e kōkua ana i ka ʻeleʻele kalapona e hoʻopuehu like ʻia ma loko o ka matrix polymer. ʻOi aku ka maikaʻi o ka hoʻopuehu ʻana e kōkua i ka resistivity volume haʻahaʻa a paʻa hoʻi me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka ʻili o ka papa pale, e hōʻemi ana i nā hemahema interface a me ka hoʻolaha ʻana i ka pilina maikaʻi me ka papa insulation.
Hana Uila Paʻa
I ka wā o ka lawelawe ʻana, ʻike nā uwea mana uila waena a me ke kiʻekiʻe i nā loli mau o ka mahana i ka wā e loli ai nā ukana hana. No laila, pono ka papa pale semi-conductive e mālama i nā waiwai uila paʻa ma luna o kahi pae mahana ākea.
Me kahi ʻano hana i hoʻonohonoho pono ʻia, hiki i nā hui pale semi-conductive i hoʻokumu ʻia ma EBA ke hāʻawi i kahi pūnaewele conductive paʻa a hōʻemi i nā loli resistivity i hoʻokumu ʻia e nā loli mahana. Kōkua kēia i ka mālama ʻana i kahi kahua uila like a hāʻawi i ka hilinaʻi lōʻihi o ke kaula.
Ke kūpaʻa wela maikaʻi loa
Ua hoʻolālā ʻia nā uwea mana e hana mau ma nā mahana kiʻekiʻe no nā makahiki he nui, e lilo ana ke kūpaʻa ʻana i ka wela i waiwai nui o nā mea pale semi-conductive.
Ke hoʻohālikelike ʻia me kekahi mau ʻōnaehana polymer maʻamau, hāʻawi ʻo EBA i ka paʻa wela maikaʻi. Ma hope o ka hoʻolōʻihi ʻana o ka wela, hiki i nā hui i hoʻokumu ʻia e EBA ke mālama maikaʻi i ko lākou mau waiwai mechanical a me ke kūpaʻa kūkulu, e kōkua ana i ka hoʻolōʻihi ʻana i ke ola lawelawe o ka papa pale a me ka ʻōnaehana kaula holoʻokoʻa.
He Kaulike Maikaʻi o ka Ikaika a me ka Maʻalahi
Ma o ka hoʻokuʻu ʻana o ke kaula, ke kaula ʻana, ka halihali ʻana, ke kau ʻana, a me ka lawelawe lōʻihi, ua kau ʻia ka papa pale semi-conductive i nā ʻano kaumaha mechanical like ʻole, me ke kaomi, ke kūlou ʻana, a me ke kaʻapuni thermal.
Hāʻawi nā hui pale i hoʻokumu ʻia e EBA i kahi hui kaulike o ka ikaika mechanical a me ka elongation, e hāʻawi ana i ka maʻalahi maikaʻi loa me ka mālama ʻana i ke kūpaʻa maikaʻi i ka haki ʻana. Kōkua kēia mau waiwai i ka hoʻokō ʻana i nā koi hana a me ka hana lōʻihi o nā kaula mana waena a me ke kiʻekiʻe.
Ka Hiki i ka Wā E Hiki Mai Ana ma nā Hoʻohana Uea HVDC
I ka hoʻomau ʻana o ka hoʻomohala ʻana o ka ʻenehana hoʻoili High-Voltage Direct Current (HVDC), pono ka hana kiʻekiʻe aʻe mai nā mea pale semi-conductive.
Ma waho aʻe o ka hāʻawi ʻana i ka conductivity uila paʻa, he kuleana koʻikoʻi nō hoʻi ka papa pale semi-conductive i ka hōʻemi ʻana i ka hoʻokomo ʻana o ka uku hakahaka i loko o ka ʻōnaehana insulation. I nā makahiki i hala iho nei, ua huki nā mea semi-conductive i hoʻokumu ʻia e EBA i ka nānā nui ʻana no nā noi kaula HVDC. Ma o ka hoʻonui ʻana i nā ʻōnaehana resin a me nā ʻano hoʻopihapiha hana, loaʻa i nā hui EBA ka hiki ke hoʻomaikaʻi hou aku i ke ʻano o ka uku hakahaka a hāʻawi i nā ʻōnaehana insulation hilinaʻi no nā kaula HVDC.
Nā Manaʻo Koʻikoʻi i ka Hoʻohana ʻana iā EBA
ʻOiai hāʻawi ʻo EBA i nā pono he nui, pono e noʻonoʻo ʻia kona mau waiwai i ka wā o ka hoʻomohala ʻana a me ka hana ʻana i ka hoʻohuihui ʻana.
Eia kekahi laʻana, hiki i ka ʻeleʻele kalapona alakaʻi ke omo maʻalahi i ka makū, no laila he mea nui ka kaohi pono ʻana i ka makū i ka wā e mālama ai, lawelawe ʻana, a me ka hana ʻana. Eia kekahi, hōʻike ʻo EBA i nā ʻano kahe hoʻoheheʻe like ʻole mai nā mea insulation polyethylene-based, e koi ana i ka hoʻonui kūpono ʻana o nā kūlana hana co-extrusion. Hoʻopilikia pū ka ʻike butyl acrylate (BA) i ka maʻalahi, ka hiki ke hana, a me ka hoʻohālikelike interface, no laila he mea nui ke koho ʻana i ka papa EBA kūpono no nā ʻano kaula like ʻole a me nā koi noi.
Hopena
I ka hoʻomau ʻana o ka ulu ʻana o nā uwea mana voltage waena a me ke kiʻekiʻe, nā uwea ikehu hou, a me nā ʻōnaehana hoʻoili HVDC, manaʻo ʻia nā hui pale semi-conductive e hāʻawi i nā pae kiʻekiʻe o ke kūpaʻa uila, ka hoʻohālikelike ʻana o ka interface, ke kū'ē ʻana i ka ʻelemakule thermal, a me ka hana hana.
Me kona hoʻopuehu ʻeleʻele kalapona maikaʻi loa, ka hana uila paʻa, ke kūpaʻa ikaika i ka ʻelemakule wela, a me nā ʻano hana hana koʻikoʻi, ua lilo ka resin EBA i hoʻokahi o nā resins kumu koʻikoʻi no nā hui pale semi-conductive hana kiʻekiʻe a manaʻo ʻia e pāʻani i kahi kuleana koʻikoʻi i ka hoʻomohala ʻana i nā mea kaula hanauna e hiki mai ana.
