Ua hoʻomohala ʻo DuPont i ka ʻenehana patent no ka hoʻohui ʻana a me ka hana ʻana o nā resins foam fluoropolymer.ʻO ke kaʻina hana ʻōhū e pili ana i ka hoʻokomo mau ʻana o kahi kinoea e like me ka nitrogen i loko o kahi extruder i hoʻopiha ʻia me ka resin hehee.Hoʻohana maʻamau ʻia kahi wili extruder i hoʻolālā ʻia e hana i ka hui kinoea polymer me kahi pūʻolo nucleating inert i loko o ka resin e kōkua i ka ulu ʻana o ke kelepona.Ua hōʻike ʻia nā ʻōpala a hiki i ka 60% void ma o ka hoʻohana ʻana i kēia kaʻina hana.
Nā noi no nā resins perfluorinated hehee
Loaʻa i nā resins perfluorinated FEP a me PFA nā viscosities hoʻoheheʻe haʻahaʻa no ka hana ʻana i nā extruder hoʻoheheʻe.Hoʻohui ʻia, kūpono ʻo FEP a me PFA no ka extrusion foaming aʻo ka mālama ʻana i kā lākou mau dielectric haʻahaʻa a me nā mea hoʻohaʻahaʻa haʻahaʻa, pono ʻelua no nā hui wili a me nā insulations cable coaxial.
Hoʻohana ʻia nā kelepona ʻikepili i ka lawe ʻana i nā hōʻailona uila ma nā ʻano hoʻonohonoho a me nā noi.ʻO nā waiwai uila koʻikoʻi e pono ai no kēia mau uwea he haʻahaʻa haʻahaʻa dielectric a me kahi kumu hoʻoheheʻe haʻahaʻa.Hiki ke hoʻonui ʻia kēia mau waiwai ma ka hoʻoulu ʻana i ka insulation.Ma muli o ka resin i hoʻohana ʻia, ʻo nā kaula i loaʻa i ka ʻūhā ʻana e ʻae i ka miniaturization o ke kaula, ka hoʻemi ʻana i ke kaumaha o ka huahana hope, a me ka hoʻouna ʻana i nā hōʻailona uila kiʻekiʻe kiʻekiʻe i nā wikiwiki hōʻailona kiʻekiʻe.
Ua kaulana loa nā kaula hū i hana ʻia mai DuPont fluoropolymer resins i ka hana kamepiula a me ka hoʻokomo ʻana i nā ʻōnaehana pūnaewele.ʻO nā uwea i hana ʻia me FEP a i ʻole PFA he mau hiʻohiʻona ahi haʻahaʻa a me ka uahi haʻahaʻa.Hiki ke hoʻokuʻu ʻia kēia mau uwea ma o nā plenums a me nā ʻauwaʻa mālama ea ʻē aʻe, e hōʻemi ana i ka pono no ka hoʻokomo ʻana i ke kumu kūʻai uila.
Hoʻolālā a me nā ʻano o nā Fluoropolymers
Ua ʻike ʻia ka PTFE e DuPont i ka makahiki 1930, akā i kēlā manawa, ʻaʻole hiki ke hoʻoheheʻe ʻia ka resin perfluorinated hou.ʻO ka noiʻi hou aʻe a DuPont i ka hoʻololi ʻana o ka hale hoʻolālā polymer i alakaʻi i ka hoʻomohala ʻana i kahi pūʻulu o nā fluoropolymers hiki ke hoʻoheheʻe ʻia e like me FEP, PFA, a me ETFE, e hoʻoikaika ana iā DuPont ma ke ʻano he alakaʻi honua i ka noiʻi fluoropolymer.
ʻO ka hiki ke hoʻoheheʻe i ka extrude i kēia mau polymers, i hui pū ʻia me nā hiʻohiʻona e like me ka haʻahaʻa dielectric mau a me ka haʻahaʻa haʻahaʻa i hana ʻia ʻo FEP a me PFA i kūpono no nā noi uea a me nā kelepona.
Nā ʻano kino maʻamau o PTFE, PFA, FEP, a me ETFE
