Ua noʻonoʻo paha ʻoe i ka ʻokoʻa ma waena o ke kalapona a mesilaka carbide mechanical sila? Ma kēia moʻomanaʻo moʻomanaʻo, e luʻu mākou i nā waiwai kūʻokoʻa a me nā noi o kēlā me kēia mea. Ma ka hopena, e ʻike maopopo ʻoe i ka wā e koho ai i ke kalapona a i ʻole ka silicon carbide no kāu mau mea e hoʻopaʻa ai, e hāʻawi ana iā ʻoe i ka manaʻo e hoʻoholo i kāu mau papahana.
Pono o na helehelena sila kalapona
He mea maʻamau ka carbon nomaka maka sila mechanicalma muli o kona mau waiwai kū hoʻokahi. Hāʻawi ia i nā hiʻohiʻona lubricating maikaʻi loa, e kōkua i ka hōʻemi ʻana i ka friction a me ka ʻaʻahu ma waena o nā maka sila i ka wā o ka hana. Hōʻike pū ʻo Carbon i ka conductivity thermal maikaʻi, e ʻae iā ia e hoʻopau maikaʻi i ka wela a pale i ke kūkulu ʻana o ka wela ma ke kikowaena sila.
ʻO kekahi pōmaikaʻi ʻē aʻe o nā maka sila kalapona ʻo ko lākou hiki ke hoʻohālikelike i nā hemahema liʻiliʻi a i ʻole nā kuhi hewa ʻana i ka ʻili male. Mālama kēia adaptability i kahi sila paʻa a hōʻemi i ka leakage. ʻAʻole kūʻē ʻo Carbon i nā ʻano kemika nui, kūpono ia no ka hoʻohana ʻana i nā noi ʻoihana like ʻole.
ʻO nā hiʻohiʻona o nā maka sila silika karbida
ʻO Silicon carbide (SiC) kahi koho kaulana ʻē aʻe no nā maka seal mechanical ma muli o kona ʻano paʻakikī a me ke kūpaʻa ʻana. Hiki i nā maka sila SiC ke kū i nā kūlana hana koʻikoʻi, me nā kaomi kiʻekiʻe, nā mahana, a me nā media abrasive. ʻO ke koʻikoʻi wela o ka mea e kōkua i ka hoʻopau ʻana i ka wela, ka pale ʻana i ka distortion thermal a me ka mālama pono ʻana i ka sila.
Hāʻawi pū nā maka sila SiC i ke kūpaʻa kemika maikaʻi loa, e kūpono iā lākou no ka hoʻohana ʻana i nā kaiapuni corrosive. ʻO ka hoʻopau maʻemaʻe o ka SiC e hōʻemi i ka friction a me ka lole, e hoʻolōʻihi i ke ola o ka sila mechanical. Hoʻohui ʻia, hāʻawi ka modulus kiʻekiʻe o ka elasticity o SiC i ke kūpaʻa dimensional, e hōʻoiaʻiʻo ana i nā maka sila e palahalaha a kūlike i ka wā o ka hana.
ʻOkoʻa ma waena o Carbon a me Silicon Carbide
Hoʻohui a me ka hoʻolālā
Hana ʻia nā sila mīkini kalapona mai ka graphite, kahi ʻano kalapona i ʻike ʻia no kāna mau waiwai lubricating ponoʻī a me ke kūpaʻa ʻana i ka wela a me ka hoʻouka kaua. Hoʻokomo pinepine ʻia ka graphite me ka resin a i ʻole metala e hoʻomaikaʻi ai i kona mau pono mechanical.
ʻO ka silikoni carbide (SiC) he mea paʻakikī a paʻa i ka ʻaʻahu i haku ʻia me ke silikoni a me ke kalapona. Loaʻa iā ia kahi ʻano crystalline e hāʻawi i kona paʻakikī maikaʻi loa, ka conductivity thermal, a me ke kūpaʻa kemika.
Paʻa Paʻa a Wear
ʻOi aku ka paʻakikī o Silicon carbide ma mua o ke kalapona, me ka paʻakikī Mohs o 9-9.5 i hoʻohālikelike ʻia me 1-2 no ka graphite. ʻO kēia paʻakikī kiʻekiʻe e hoʻoikaika loa iā SiC i ka lole abrasive, ʻoiai i nā noi noi me ka media abrasive.
ʻO nā sila kalapona, ʻoiai ʻoi aku ka palupalu, ke hāʻawi mau nei i ke kūpaʻa maikaʻi i ka ʻaʻahu ʻana i nā kaiapuni non-abrasive. ʻO ke ʻano lubricating ponoʻī o ka graphite e kōkua i ka hōʻemi ʻana i ka friction a me ka ʻaʻahu ma waena o nā maka sila.
Kūleʻa wela
Loaʻa i nā ʻāpana kalapona a me ka silicon carbide nā waiwai wela kiʻekiʻe. Hiki i nā sila kalapona ke hana maʻamau i nā mahana a hiki i 350°C (662°F), aʻo nā sila carbide silicon hiki ke kū i nā mahana kiʻekiʻe, ʻoi aku ma mua o 500°C (932°F).
ʻOi aku ka kiʻekiʻe o ka conductivity thermal o ka silicon carbide ma mua o ke kalapona, e ʻae ana i nā sila SiC e hoʻopau maikaʻi i ka wela a mālama i kahi haʻahaʻa haʻahaʻa haʻahaʻa ma ke kikowaena sealing.
Palekana Kemika
ʻO ka silikoni carbide he mea kemika a kūpaʻa i ka hoʻouka ʻana mai ka hapa nui o nā waikawa, nā kumu, a me nā solvents. He koho maikaʻi loa ia no ka hoʻopaʻa ʻana i ka media corrosive a i ʻole ka hoʻopaʻapaʻa.
Hāʻawi pū ʻo Carbon i ke kūpaʻa kemika maikaʻi, ʻoi aku ka nui o nā pūhui organik a me nā ʻakika non-oxidizing a me nā kumu. Eia nō naʻe, ʻaʻole kūpono ia no nā kaiapuni hoʻoneʻe ikaika a i ʻole nā noi me ka media pH kiʻekiʻe.
Uku a me ka Loaʻa
ʻOi aku ka liʻiliʻi o nā sila mīkini kalapona ma mua o nā sila carbide silicon ma muli o ke kumu kūʻai haʻahaʻa o nā mea maka a me nā kaʻina hana maʻalahi. Loaʻa nui nā sila kalapona a hiki ke hana ʻia ma nā ʻano papa like ʻole a me nā hoʻonohonoho.
ʻOi aku ka loea o nā sila silikoni carbide a hele mai ma ke kumu kūʻai kiʻekiʻe. Pono ka hana ʻana o nā ʻāpana SiC kiʻekiʻe i nā ʻenehana hana kiʻekiʻe a me ka mana koʻikoʻi koʻikoʻi, e hāʻawi ana i ka piʻi ʻana o ke kumukūʻai.
ʻO ka wā e hoʻohana ai i ka sila kalapona
He kūpono nā alo o ka carbon sila no nā noi e pili ana i nā haʻahaʻa haʻahaʻa a haʻahaʻa haʻahaʻa a me nā mahana. Hoʻohana maʻamau ʻia lākou i loko o nā pā wai, nā mea hui, a me nā mea hoʻouluulu kahi i hoʻopaʻa ʻole ʻia ai ka mea hoʻopaʻa paʻa. He kūpono hoʻi nā sila kalapona no ka hoʻopaʻa ʻana i nā wai me nā waiwai lubricating maikaʻi ʻole, ʻoiai ʻo ka mea kalapona ponoʻī e hāʻawi i ka lubrication.
Ma nā noi me nā pōʻai hoʻomaka pinepine a i ʻole kahi e ʻike ai ka lāʻau i ka neʻe axial, hiki i nā alo o ke kalapona ke hoʻokipa i kēia mau kūlana ma muli o ko lākou mau pono lubricating a me ka hiki ke hoʻohālikelike i nā hewa liʻiliʻi i ka ʻili male.
I ka manawa e hoʻohana ai i ka Sila Silicon Carbide
ʻOi aku ka maikaʻi o nā maka sila silikoni carbide i nā noi e pili ana i nā kaomi kiʻekiʻe, nā mahana, a me nā media abrasive a corrosive. Hoʻohana pinepine ʻia lākou i ke koi ʻana i nā kaʻina hana ʻoihana, e like me ka hana ʻaila a me ke kinoea, ka hana kemika, a me ka hana mana.
He kūpono hoʻi nā sila SiC no ka hoʻopaʻa ʻana i nā wai maʻemaʻe kiʻekiʻe, no ka mea ʻaʻole lākou e hoʻohaumia i ka media i hoʻopaʻa ʻia. Ma nā noi kahi i loaʻa ai nā waiwai lubricating maikaʻi ʻole o ka media sealing, ʻo ka coefficient haʻahaʻa o ka friction a me ke kūpaʻa ʻana o SiC he koho maikaʻi loa ia.
Ke hoʻokau ʻia ka sila mechanical i ka hoʻololi pinepine ʻana i ka wela a i ʻole nā haʻalulu wela, ʻo ka conductivity thermal kiʻekiʻe o SiC a me ke kūpaʻa dimensional e kōkua i ka mālama ʻana i ka hana sila a me ka lōʻihi. Hoʻohui ʻia, kūpono nā sila SiC no nā noi e koi ana i ke ola lawelawe lōʻihi a me ka mālama liʻiliʻi ma muli o ko lākou kūpaʻa kūʻokoʻa a me ke kūpaʻa ʻana i ka lole.
FAQs
ʻO wai ka mea hoʻohana i hoʻohana pinepine ʻia?
Hoʻohana pinepine ʻia ʻo Carbon i nā sila mechanical ma muli o kona kumukūʻai haʻahaʻa a me ka hana kūpono i nā noi he nui.
Hiki ke hoʻohana like ʻia nā sila kalapona a me ka silika?
I kekahi mau hihia, ʻae, akā pili ia i nā koi noi kikoʻī, e like me ka mahana, ke kaomi, a me ka pili ʻana o ka wai.
I ka hopena
I ke koho ʻana ma waena o ka carbon a me ka silicon carbide mechanical seal, e noʻonoʻo i nā koi noi kikoʻī. Hāʻawi ʻo Silicon carbide i ka paʻakikī a me ke kūpaʻa kemika, ʻoiai ke hāʻawi nei ke kalapona i ka hiki ke holo maloʻo maikaʻi.
