ʻO nā pad brake Ceramic kahi ʻano o ka pahu pahu e komo pū ana me ka fiber mineral, ka fiber aramid a me ka fiber ceramic (no ka mea hiki i ke kaula kila ke ʻōpala, hana i ka walaʻau a me ka lepo, a no laila ʻaʻole hiki ke hoʻokō i nā koi o nā ʻano ʻano ceramic).
He nui nā mea kūʻai aku e kuhi mua i ka ceramic i hana ʻia me ka ceramic, akā ʻo ka mea ʻoiaʻiʻo, ua hana ʻia nā pā palaka ceramic mai ke kumu o nā ceramics metala ma mua o nā ceramics non-metal.Ma kēia wela kiʻekiʻe, e hoʻoheheʻe ʻia ka ʻili o ka pahu pahu i ka metala-ceramic e like me ka hopena, no laila ke kūpaʻa maikaʻi ka pahu pahu i kēia mahana.ʻAʻole hana nā pad brake kuʻuna i nā hopena sintering i kēia mahana, a ʻo ka piʻi nui ʻana o ka mahana o ka ʻili e hiki ke hoʻoheheʻe i ka mea ʻili a hoʻoheheʻe paha i kahi cushion o ka ea, hiki ke hoʻohaʻahaʻa i ka hana brake ma hope o ka hoʻomau mau ʻana a i ʻole ka pau ʻana. o ke kaa ana.
Loaʻa i nā pad brake ceramic nā mea maikaʻi ma mua o nā ʻano ʻano ʻē aʻe.
(1) ʻO ka ʻokoʻa nui loa ma waena o nā pad brake ceramic a me nā pad brake kuʻuna ʻo ka nele o ka metala.I loko o nā pad brake maʻamau, ʻo ka metala ka mea nui e hoʻoulu ai i ka friction, he ikaika ka braking kiʻekiʻe, akā hiki ke ʻaʻahu a me ka walaʻau.Ke hoʻokomo ʻia nā pā palaka ceramic, ʻaʻohe hoʻopaʻapaʻa ʻokoʻa (ʻo ia hoʻi ke kani ʻana o ke kani) i ka wā o ka hoʻokele maʻamau.No ka loaʻa ʻole o nā ʻāpana metala i loko o nā pad brake seramika, ua pale ʻia ke kani kani ʻana o nā pad brake metala kuʻuna e ʻānai ana kekahi i kekahi (ʻo ia hoʻi nā pale pahu a me nā disc brake).
(2) Paʻa paʻa kuʻi.ʻO ke koena friction ka hōʻailona hana koʻikoʻi o nā mea friction, pili i ka maikaʻi a maikaʻi ʻole paha o ka brake pads.I ke kaʻina hana braking ma muli o ka wela i hana ʻia e ka friction, piʻi ka mahana hana, ʻo ka mea friction maʻamau o ka pahu pahu e ka mahana, hoʻomaka ka emi ʻana o ka coefficient o ka friction.I ka hoʻohana maoli ʻana, e hōʻemi ia i ka ikaika friction, pēlā e hōʻemi ai i ka hopena braking.ʻAʻole i oʻo ka mea friction o nā pad brake maʻamau, a ʻoi aku ka kiʻekiʻe o ka friction coefficient e kumu i nā kumu palekana e like me ka nalowale o ke kuhikuhi i ka wā e hoʻopaʻa ʻia ai, nā pad i puhi ʻia a me nā disc brake scratched.ʻOiai ke kiʻekiʻe o ka wela o ka disc brake e like me 650 degere, ʻo ka friction coefficient o nā pad brake ceramic ma kahi o 0.45-0.55, hiki ke hōʻoia i ka hana braking maikaʻi o ke kaʻa.
(3) He ʻoi aku ka maikaʻi o ke kūpaʻa wela a me ka conductivity thermal haʻahaʻa, a me ke kūpaʻa maikaʻi ʻana.ʻO ka mahana hoʻohana lōʻihi ma 1000 degere, hiki i kēia hiʻohiʻona ke kūpono i nā ʻano mea hana kiʻekiʻe kiʻekiʻe, nā koina hana kiʻekiʻe, hiki ke hoʻokō i ka pahu pahu kiʻekiʻe kiʻekiʻe, palekana, pale lole kiʻekiʻe a me nā koi ʻenehana ʻē aʻe.
(4) Loaʻa iā ia ka ikaika mechanical a me nā waiwai kino.Hiki ke pale i ke kaomi nui a me ka ikaika ʻā.ʻO nā huahana friction material i loko o ka hui ma mua o ka hoʻohana ʻana, pono ka wili ʻana, ka hui ʻana a me nā hana ʻenehana ʻē aʻe, i mea e hana ai i ka hui ʻana o ka brake pad.No laila, pono e loaʻa i ka mea friction ka ikaika mechanical e hōʻoia i ka ʻike ʻole ʻana o ka hana ʻana a i ʻole ka hoʻohana ʻana o ke kaʻina hana i ka haki a haki.
(5) Loaʻa ka waiwai palaho wela haʻahaʻa loa.
(6) Hoʻonui i ka hana o nā pale pale.Ma muli o ka wikiwiki o ka wela o nā mea seramika, hoʻohana ʻia ia i ka hana ʻana i nā kaʻa, a ʻoi aku ka kiʻekiʻe o kāna coefficient o ka friction ma mua o nā pad brake metala.
(7) Palekana.Hoʻopuka nā pad brake i ka wela kiʻekiʻe koke i ka wā e haʻi ai, ʻoi aku ka wikiwiki a i ʻole ka ulia pōpilikia.I ke kūlana wela kiʻekiʻe, e hāʻule ka heluna friction o nā pad friction, i kapa ʻia ʻo thermal recession.Hoʻohaʻahaʻa haʻahaʻa haʻahaʻa kiʻekiʻe a me ka ulia pōpilikia i ka wā e piʻi ai ka mahana o ka pahu pahu i mea e lohi ai ka brake braking, a i ʻole ka nalo ʻana o ke kumu palekana hopena braking.
(8) hōʻoluʻolu.Ma waena o nā hōʻailona hōʻoluʻolu, hopohopo pinepine ka poʻe nona ka leo o nā pad brake, ʻoiaʻiʻo, ʻo ka walaʻau kekahi pilikia lōʻihi ʻaʻole hiki ke hoʻoponopono ʻia e nā pad brake maʻamau.Hoʻokumu ʻia ka walaʻau e ka friction maʻamau ma waena o ka friction pad a me ka friction disc, a ʻo nā kumu o kāna hana ʻana he paʻakikī loa, e like me ka ikaika braking, ka mahana o ka disc brake, ka wikiwiki o ke kaʻa a me nā kūlana climatic. ʻO nā kumu kūpono no ka walaʻau.
(9) Nā hiʻohiʻona waiwai maikaʻi loa.Hoʻohana ʻia nā pāpaʻi seramika i nā ʻāpana nui o ka graphite/brass/advanced ceramic (non-asbestos) a me semi-metal a me nā mea ʻenehana kiʻekiʻe me ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa ʻana, ka paʻa paʻa, ka hoʻoponopono ʻana i ka ʻeha disc brake, ka palekana o ke kaiapuni, ʻaʻohe leo lōʻihi. ʻO ke ola lawelawe a me nā pono ʻē aʻe, e lanakila ai i nā mea pad brake kuʻuna a me nā hemahema kaʻina hana, ʻo ia ka mea maʻalahi loa o ka honua holomua ceramic brake pads.Eia kekahi, hiki i ka haʻahaʻa haʻahaʻa o ka pōpō slag ceramic a me ka hoʻonui maikaʻi ke hōʻemi i ka ʻaʻahu a me ka walaʻau o nā pad brake.
(10) Ke ola lawelawe lōʻihi.ʻO ke ola lawelawe kahi hōʻailona o ka hopohopo nui.ʻO ke ola lawelawe o nā pad brake maʻamau ma lalo o 60,000 km, ʻoiai ʻo ke ola lawelawe o nā pad brake ceramic ma luna o 100,000 km.ʻO ia no ka hoʻohana ʻana o nā pad brake ceramic i kahi ʻano kūʻokoʻa o 1 wale nō i 2 mau ʻano o ka pauka electrostatic, ʻo nā mea ʻē aʻe he mau mea non-static, no laila e lawe ʻia ka pauda e ka makani me ka neʻe ʻana o ke kaʻa, ʻaʻole e pili. i ka huila huila e pili i ka nani.ʻOi aku ka nui o ke ola o nā mea seramika ma mua o 50% ma mua o nā mea semi-metal maʻamau.Ma hope o ka hoʻohana ʻana i nā pad brake ceramic, ʻaʻole e ʻoki ʻia nā ʻōpala (ʻo ia hoʻi nā ʻōpala) ma nā disc brake, e hoʻolōʻihi i ke ola lawelawe o nā disc kumu e 20%.
