Wahi mua: I kēia manawa, i ka ʻoihana kaʻa i ka pōʻaiapili o ka electrification, ka naʻauao a me ka hoʻomaikaʻi ʻana i nā huahana automotive, ke piʻi mālie nei nā koi o ka ʻōnaehana brake, a ʻoi aku ka maikaʻi o nā disc brake carbon ceramic, e kamaʻilio kēia ʻatikala e pili ana i ka disc brake carbon ceramic. ʻoihana.
I. Kahua Hana
I kēia mau lā, ua hoʻokuʻu ʻo Azera i kāna SUV nui ʻelima mau noho, ʻo ka ES7, ka mea e hoʻohana ana i kahi pahu hoʻohui i hoʻohui ʻia a pau-aluminum hope, ʻo ka lua o ka manawa hoʻohana ʻo Azera i ka ʻenehana make-casting i hoʻohui ʻia i kāna mau huahana.Me ka hoʻomohala ʻana o ka māmā a me ka electrification, ke ʻimi ʻia nei ka ʻenehana make-casting i hoʻohui ʻia e nā mea hana kaʻa hou a me nā ʻoihana kaʻa maʻamau, a ʻo ka māmā o ke kaʻa kaʻa i kanalua ʻole i lilo i ʻāpana o ka hoʻolālā kaʻa hou.ʻO ka hoʻohana ʻana i nā disc brake carbon ceramic e hoʻoikaika ikaika i ke kaʻina hana o ka māmā māmā, ʻo ia ka mea e kamaʻilio e pili ana i kēia ʻoihana.
ʻElua, hoʻomaopopo i nā disc brake carbon ceramic
I kēia manawa, hoʻohana nui ʻia nā mea kīwaha i nā kaʻaahi kiʻekiʻe, nā kaʻa a me nā mokulele i ka pauka metallurgy a me ka carbon-carbon composite material.Eia nō naʻe, he mau hemahema ka pauda metalalurgy brake mea e like me ke kiʻekiʻe kiʻekiʻe wela maʻalahi paʻa, friction hana maʻalahi e emi, kiʻekiʻe wela ikaika emi nui, ilihune thermal haʻalulu kū'ē, pōkole lawelawe ola, etc.;ʻoiai he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka pulu kalapona nā mea hao kalapona, nui ka nui o ka mālama ʻana i ka wela, lōʻihi ka pōʻai hana a me ke kumu kūʻai kiʻekiʻe, e kaupalena ana i kona hoʻomohala hou ʻana a me ka noi.
Hoʻohui nā disc brake carbon ceramic i nā waiwai kino o ka fiber carbon a me ka polycrystalline silicon carbide.I kēia manawa, ʻo ke kaumaha māmā, ka paʻakikī maikaʻi, ke kūpaʻa ma lalo o ke kiʻekiʻe kiʻekiʻe a me ke kiʻekiʻe o ka wela, ke kū ʻana o ka haʻalulu wela a me nā ʻano ʻoki ʻoki ʻoki o ka paʻakikī like ʻaʻole e hoʻolōʻihi i ke ola lawelawe o ka disc brake, akā e pale pū i nā pilikia āpau mai ka ukana.
ʻO ke kolu, ke kūlana o ka ʻoihana i kēia manawa
1. ʻOi aku ka maikaʻi o ka hoʻokō ʻana o ka disc brake carbon ceramic ma mua o ka pahu pahu pahu hina hina maʻamau, akā ʻo ke kumu kūʻai o kona mau hemahema.
I kēia manawa, ʻo nā mea i hoʻohana nui ʻia i ka disc brake i ka hao maʻamau, ka hao haʻahaʻa haʻahaʻa, ke kila hoʻolele maʻamau, ke kila hoʻoheheʻe kūikawā, ke kila haʻahaʻa haʻahaʻa a me ka hao hoʻoheheʻe ʻia a me ke kila hoʻoheheʻe ʻia (forged steel) composite material, cast iron. ʻoi aku ka nui o nā mea i hoʻohana ʻia.He lōʻihi ka hana ʻana o nā mea hao hao, maikaʻi ʻole ka thermal conductivity a maʻalahi hoʻi e hana i nā māwae wela a me nā hemahema ʻē aʻe, no laila ke kalapona a me ka carbon ceramic composite mea no ka hoʻomohala ʻana i nā mea ʻoki.
Ma muli o ke kumukūʻai kiʻekiʻe o ka carbon-carbon composite material, i hoʻohana nui ʻia no nā mokulele mokulele, me ka hoʻomohala ʻana i nā kaʻaahi kiʻekiʻe kiʻekiʻe i nā makahiki i hala iho nei, ua hoʻomaka nā ʻepekema kūloko a me nā ʻāina ʻē e hoʻomohala i ka hoʻomohala ʻana i nā ala kaʻa kiʻekiʻe no ka carbon ceramic composite friction vice. , carbon ceramic composite material mea he international focus on the development of friction materials , Kina no hoi i ka papa mua, carbon ceramic brake discs i ka wā e hiki mai ana e hoemi i ke kumu kūʻai o ka nui, ua manaoia e lilo i ka ulu nui o ka pahu huahana Ua manaʻo ʻia e lilo i alakaʻi hoʻomohala nui o nā huahana brake.
2. He ha'aha'a loa ke kumu kū'ai o nā disc brake carbon ceramic, a he wahi nui no ka ho'emi 'ana i ka 'enehana a me ka unahi.
I ka makahiki 2021, he 370,000 yuan/ton ke kumu kūʻai hoʻokahi ton o nā huahana kahua wela o ka ʻoihana, ma lalo o 20% mai 460,000 yuan/ton i ka makahiki 2017, a ʻo ke kumu kūʻai hana hoʻokahi-ton he 11.4 miliona yuan i 2021, iho 53.8% mai ʻO 246,800 yuan i ka makahiki 2017, he hōʻemi koʻikoʻi koʻikoʻi.I ka makahiki 2021, ʻo 52% ke kumukūʻai kumu kūʻai.Me ka hoʻonui ʻana i ka pālākiō, ka hoʻonui ʻana i ka ʻenehana, ka hoʻomaikaʻi ʻana i ka pae automation a me ka emi ʻana o ke kumukūʻai carbon fiber, aia kahi wahi nui no ka hōʻemi ʻana i nā kumukūʻai huahana.ʻO ke kumukūʻai ʻāpana kalapona kalapona i kēia manawa ma kahi o 2500-3500 yuan, no ka mea me ka papa C a ma luna o ka mākeke kaʻa kaʻa, ua manaʻo ʻia i ka makahiki 2025 e hāʻule ka waiwai hoʻokahi ma kahi o 1000-1200 yuan. i ka papa B a ma luna o ka mākeke kaʻa kaʻa.
ʻEhā, manaʻolana ʻoihana
1. Loaʻa i nā disc brake carbon ceramic kahi ākea no ka pani hale
Ma muli o ka paʻakikī o ke kaʻina hana, ka paʻakikī o ka hana ʻana, ka lōʻihi o ka hana ʻana a me nā paepae ʻē aʻe, ʻoi aku ka liʻiliʻi o nā ʻoihana kūloko e hiki ke hana nui i nā disc carbon ceramic.ʻO nā mea hoʻolako nui o ka carbon ceramic composite brake discs me Brembo (Italia), Surface Transforms Plc (UK), Fusionbrakes (USA), a pēlā aku. he wahi nui no ka pani hale.
ʻO nā mea kūʻai nui o nā mea hana kaʻa kalapona ceramic brake disc ma waho he mau mea hana kaʻa haʻuki kiʻekiʻe, a ʻoi aku ka kiʻekiʻe o ke kumukūʻai o nā huahana.E lawe i ka hui o nā ʻāina ʻē ʻo Brembo ma ke ʻano he laʻana, ʻoi aku ke kumukūʻai o ka disc carbon ceramic hoʻokahi ma mua o 100,000 RMB, ʻoiai ʻo ka waiwai o kahi disc carbon ceramic home e pili ana i 0.8-12,000 RMB, a he hana kiʻekiʻe loa.Me ka hoʻomau ʻana o ka ʻenehana ʻenehana o nā ʻoihana kūloko ma kēia kahua, a me ka hoʻomau mau ʻana o ke ʻano o nā kaʻa ikaika hou "hoʻohui, kiʻekiʻe, naʻauao", e hoʻomau ka piʻi ʻana o ka piʻi ʻana o nā disc carbon ceramic no nā kaʻa ikehu hou.
2. Loaʻa nā disc brake carbon ceramic i ke ʻano o ka māmā māmā
Hōʻike nā hōʻike hoʻokolohua he 10% ka emi ʻana o ke kaumaha o ke kaʻa hiki ke hoʻonui i ka pono wahie e 6% - -8%;no kēlā me kēia 100 kg ka emi ʻana o ka nui o ke kaʻa, hiki ke hoʻemi ʻia ka hoʻohana wahie e 0.3 - -0.6 lita no 100 km, no laila ʻo ka ʻenehana māmā ke kuhikuhi hoʻomohala nui no nā kaʻa e hiki mai ana.
E ho'ēmi i ka nui ma lalo o ka ʻōnaehana hoʻokuʻu me ka hapalua o ka hoʻoikaika ʻana, ʻo carbon ceramic brake disc ka mea nui e hōʻemi i ke kaumaha.ʻO kēlā me kēia hōʻemi 1kg ma lalo o ka ʻōnaehana hoʻokuʻu e like me ka hoʻemi ʻana he 5kg ma luna o ka ʻōnaehana hoʻomaha.ʻO kahi pālua o 380mm nui carbon ceramic discs ma kahi o 20kg ka māmā ma mua o nā disiki hao hina hina, ua like ia me ka ho'ēmi kaumaha 100kg i ka ʻōnaehana hoʻokuʻu o ke kaʻa.Eia hou, ua hele ka Toyota Lexus RCF ma o ka CFRP mea a me carbon ceramic brake discs e hoemi i ke kaumaha o 70kg ma na mea he nui, o ka 22kg i haawiia e ka carbon ceramic brake discs, no laila, carbon ceramic brake discs no ka nā māhele koʻikoʻi o ka hoʻemi kaumaha o ke kaʻa.

ʻO ka hoʻololi ʻana i ka disc brake metallurgy pauda kumu ʻo ia ke ʻano hiki ʻole o kēia ʻoihana: ʻo ka mua, e emi mālie ke kumukūʻai o ke kalapona kalapona e hoʻoiho i ke kumu kūʻai pololei o ka huahana ponoʻī;ʻO ka lua, me ka piʻi ʻana o ka hana a me nā mea kūʻai aku, ʻo ka optimization o ka loulou kaʻina hana, e hoʻohaʻahaʻa ka hoʻokele waiwai i ke kumukūʻai o ka disc brake carbon ceramic;ʻO ke kolu, ʻo ka ʻike hoʻokele palekana e paipai i ka hoʻonui ʻana i nā huahana i ka ʻoihana kaʻa.Manaʻo ʻia ʻo 2023 ka makahiki mua o ka hoʻolaha disc brake carbon ceramic.ʻO ka makahiki mua o ka hoʻolaha ʻana i ka disc brake, ua manaʻo ʻia ka mākeke kūloko a hiki i 7.8 biliona yuan i 2025, a ʻo ka nui o ka mākeke kūloko e manaʻo ʻia e ʻoi aku ma mua o 20 biliona yuan i 2030.
Ma ka makahiki 2025, he 90 biliona yuan ka nui o ka mākeke o nā disc brake metallurgy maʻamau e like me ke kumukūʻai o 1000 yuan no ka kaʻa hoʻokahi a me 90 miliona mau kaʻa i kūʻai ʻia ma ka honua holoʻokoʻa, a kokoke ka mākeke kūloko i 30 biliona yuan.Me ka wikiwiki o ka electrification, ʻoi aku ka nui o ke komo ʻana o nā disc brake carbon ceramic ma mua o kā mākou mau manaʻo.He mākeke hou kēia i kūpono i ke ʻano maʻamau o ka hoʻomohala ʻana i ka naʻauao uila a he holomua o 0-1.A no ka noʻonoʻo ʻana i ka palekana automotive, i ka manawa e lilo ai ka breakthrough i wahi kūʻai aku no ka palekana automotive, manaʻo ʻia ka nui o ka hoʻomohala ʻana ma mua o nā mea i manaʻo ʻia, a e manaʻo ʻia ka loaʻa kālā o ka mākeke holoʻokoʻa e hoʻokokoke i 200-300 billion yuan.
