Me ka hoʻonui mau ʻana o ka noi ikehu hou, ua manaʻo ʻia e komo hou ka mākeke capacitor kiʻiʻoniʻoni o Kina i kahi wā ulu kiʻekiʻe i nā makahiki e hiki mai ana.ʻO ka kiʻiʻoniʻoni polypropylene, ka mea nui o nā capacitors kiʻiʻoniʻoni, ke hoʻomau nei ka hoʻonui ʻana i kāna lako a me ke koi ʻana ma muli o ka hoʻonui wikiwiki ʻana o ka noi a me ka hoʻokuʻu lohi ʻana o ka hiki ke hana.E nānā ka ʻatikala o kēia pule i ka mea nui o nā capacitors kiʻiʻoniʻoni- polypropylene film (PP film).

I ka hopena o nā makahiki 1960, ua lilo ke kiʻi uila polypropylene i hoʻokahi o nā kiʻi ʻoniʻoni uila nui ʻekolu ma muli o kāna mau hiʻohiʻona uila a me ka hoʻoponopono ʻana a me ka maikaʻi o ke kumu kūʻai, a ua hoʻohana nui ʻia i ka ʻoihana capacitor.I nā makahiki 1980, ua hoʻomaka mua ka hana ʻana i nā capacitors kiʻiʻoniʻoni polypropylene metallized ma nā ʻāina i kūkulu ʻia ma ʻEulopa a me ʻAmelika, ʻoiai ʻo Kina i ka pae hoʻomohala o nā metallized polypropylene film capacitors.Ma o ka hoʻokomo wale ʻana i ka ʻenehana hana ʻenehana polypropylene film capacitor a me nā lako kī i loaʻa ai iā mākou nā metallized polypropylene film capacitor i ke ʻano maoli.

E ʻike kākou i ka hoʻohana ʻana i ka kiʻiʻoniʻoni polypropylene i nā capacitors kiʻiʻoniʻoni a me kahi hoʻolauna pōkole.ʻO nā capacitors kiʻiʻoniʻoni polypropylene no ka papa capacitor kiʻiʻoniʻoni organik, ʻo kona ʻano he kiʻiʻoniʻoni polypropylene, electrode he ʻano mea hoʻokipa metala a me ke ʻano kiʻiʻoniʻoni metala, ua uhi ʻia ke kumu o ka capacitor me ka resin epoxy a i hoʻopili ʻia i loko o ka pahu plastik a me ka pahu.ʻO ka capacitor polypropylene i hana ʻia me ka electrode kiʻiʻoniʻoni metala i kapa ʻia ʻo metallized polypropylene film capacitor, i ʻike maʻamau ʻia ʻo ka capacitor film.ʻO ke kiʻiʻoniʻoni polypropylene kahi resin thermoplastic i hana ʻia e ka polymerizing propylene.ʻOi aku ka mānoanoa, ʻoi aku ka paʻakikī, a ʻoi aku ka ikaika o ka tensile, a hiki ke hoʻohana ʻia no nā kiʻi ʻoniʻoni ʻōmaʻomaʻo, nā ʻeke ukana, a me nā mea ʻē aʻe. 0. 90-0.91g/cm³.ʻO ia kekahi o nā ʻano māmā loa o nā plastics āpau i loaʻa.He paʻa loa ia i ka wai, ʻo ka nui o ka absorption wai i ka wai he 0. 01% wale nō, ke kaumaha o ka molekala ma kahi o 80,000-150,000.

ʻO ke kiʻiʻoniʻoni polypropylene ka mea nui o nā capacitors kiʻiʻoniʻoni.ʻO ke ʻano hana o ka capacitor kiʻiʻoniʻoni i kapa ʻia he kiʻi ʻoniʻoni metallized, i hana ʻia e ka vacuum vaporizing i kahi ʻāpana lahilahi o ka metala ma ke kiʻi ʻoniʻoni e like me ka electrode.Hiki i kēia ke ho'ēmi i ka leo o ka capacitor unit capacity, no laila ua maʻalahi ke kiʻiʻoniʻoni e hana i nā capacitors liʻiliʻi, kiʻekiʻe.ʻO ka upstream o ka capacitor kiʻiʻoniʻoni ka mea nui e pili ana i ke kiʻiʻoniʻoni kumu, metala foil, ka uwea, ka pahu waho, a me nā mea ʻē aʻe.Hoʻokaʻawale ʻia ke kiʻi kumu i ka polypropylene a me ka polyester.ʻOi aku ka mānoanoa o ke kiʻi kumu, ʻoi aku ka kiʻekiʻe o ka volta hiki ke kū, a ʻo ia hoʻi, ʻo ka haʻahaʻa o ka volta hiki ke kū.ʻO ke kiʻi ʻoniʻoni kumu ke kiʻi uila uila, ʻoiai ʻo ka dielectric o nā capacitors kiʻiʻoniʻoni ka mea koʻikoʻi i ka upstream raw material, e hoʻoholo ana i ka hana o nā capacitors kiʻiʻoniʻoni a noho i 60% -70% o ke kumu kūʻai.Ma ke ʻano o ke ʻano o ka mākeke, loaʻa i nā mea hana Kepani ke alakaʻi maopopo i nā mea waiwai no nā capacitors kiʻiʻoniʻoni kiʻekiʻe, me Toray, Mitsubishi a me DuPont ʻo ia ka mea hoʻolako kiʻiʻoniʻoni kumu kiʻekiʻe o ka honua.

ʻO nā kiʻiʻoniʻoni polypropylene uila no nā kaʻa ikehu hou, photovoltaic a me ka makani makani ka mea nui ma waena o 2 a me 4 microns, a ua hoʻemi ʻia ka mana hana ma mua o ka hapalua i ka manawa like i hoʻohālikelike ʻia me 6 a 8 microns no nā mea hana hale maʻamau, ka hopena. i ka emi nui o ka huina hoonui a me ka hoohuli ana i ka lako kuai a me ka koi.E kaupalena ʻia ka lako o nā kiʻiʻoniʻoni polypropylene uila i nā makahiki e hiki mai ana.I kēia manawa, hana ʻia nā mea hana nui o ka kiʻiʻoniʻoni polypropylene uila honua ma Kelemania, Iapana a me nā ʻāina ʻē aʻe, a ʻo ke kaʻina hana o ka mana hou he 24 a 40 mau mahina.Eia hou, ua kiʻekiʻe nā koi hana o nā kiʻiʻoniʻoni automotive hou, a he mau hui liʻiliʻi wale nō e hiki ke hoʻopaʻa i ka hana nui o nā kiʻi polypropylene uila uila hou, no laila ma ka honua holoʻokoʻa, ʻaʻohe hiki ke hana kiʻi polypropylene hou i 2022. aia nā laina hana ma lalo o ke kūkākūkā ʻana.No laila, ʻoi aku ka nui o ke kaʻe o ka mana no ka ʻoihana holoʻokoʻa i kēia makahiki aʻe.
