Ua noʻonoʻo paha ʻoe e pili ana i nā ʻokoʻa ma waena o ke kalapona a menā sila mīkini silicon carbideMa kēia pou blog, e luʻu mākou i loko o nā waiwai kūikawā a me nā noi o kēlā me kēia mea. I ka hopena, e loaʻa iā ʻoe kahi ʻike maopopo i ka wā e koho ai i ke kalapona a i ʻole ka silicon carbide no kāu mau pono sila, e hoʻoikaika iā ʻoe e hana i nā hoʻoholo naʻauao i kāu mau papahana.
Nā Waiwai o nā ʻAoʻao Sila Kalapona
He mea hoʻohana pinepine ʻia ke kalapona nonā helehelena sila mīkinima muli o kona mau waiwai kūikawā. Hāʻawi ia i nā ʻano lubricating maikaʻi loa, e kōkua ana i ka hōʻemi ʻana i ka friction a me ka ʻaʻahu ma waena o nā ʻaoʻao sila i ka wā o ka hana. Hōʻike pū ʻo Carbon i ka conductivity thermal maikaʻi, e ʻae ana iā ia e hoʻokuʻu i ka wela me ka maikaʻi a pale i ka hōʻiliʻili ʻana o ka mahana nui ma ka interface sila.
ʻO kekahi pono o nā maka sila kalapona ʻo ko lākou hiki ke kūlike i nā hemahema liʻiliʻi a i ʻole nā kūlike ʻole i ka ʻili pili. Hōʻoia kēia hiki ke hoʻololi i kahi sila paʻa a hoʻemi i ka leakage. Kūpaʻa pū ke kalapona i nā ʻano kemika like ʻole, e kūpono ai no ka hoʻohana ʻana i nā noi ʻoihana like ʻole.
Nā Waiwai o nā ʻAoʻao Sila Silicon Carbide
ʻO Silicon carbide (SiC) kekahi koho kaulana no nā maka sila mechanical ma muli o kona paʻakikī koʻikoʻi a me ke kūpaʻa ʻana i ka ʻaʻahu. Hiki i nā maka sila SiC ke kū i nā kūlana hana koʻikoʻi, me nā kaomi kiʻekiʻe, nā mahana, a me nā mea abrasive. Kōkua ka conductivity thermal kiʻekiʻe o ka mea i ka hoʻokuʻu ʻana i ka wela, e pale ana i ka hoʻopilikia thermal a me ka mālama ʻana i ka pono o ka sila.
Hāʻawi pū nā helehelena sila SiC i ke kūpaʻa kemika maikaʻi loa, e kūpono ai no ka hoʻohana ʻana i nā wahi ʻino. ʻO ka ʻili laumania o SiC e hōʻemi ana i ka friction a me ka ʻaʻahu, e hoʻolōʻihi ana i ke ola o ka sila mechanical. Eia kekahi, ʻo ka modulus elasticity kiʻekiʻe o SiC e hāʻawi i ka paʻa dimensional, e hōʻoiaʻiʻo ana e noho pālahalaha a kūlike nā helehelena sila i ka wā o ka hana.
ʻOkoʻa ma waena o ke kalapona a me ka Silicon Carbide
Ka Hoʻohuihui a me ke ʻAno
Hana ʻia nā sila mīkini kalapona mai ka graphite, kahi ʻano kalapona i ʻike ʻia no kona mau waiwai lubrication ponoʻī a me ke kūpaʻa ʻana i ka wela a me ka hoʻouka kemika. Hoʻopiha pinepine ʻia ka graphite me ka resin a i ʻole ka metala e hoʻomaikaʻi i kona mau waiwai mechanical.
He mea keramika paʻakikī a kūpaʻa hoʻi ka Silicon carbide (SiC) i haku ʻia me ka silicon a me ke kalapona. He ʻano kristal kona e hāʻawi ana i kona paʻakikī maikaʻi loa, ka hoʻokele wela, a me ke kūpaʻa kemika.
Paʻakikī a me ke kūpaʻa ʻana i ka ʻaʻahu
ʻOi aku ka paʻakikī o ka silicone 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 ai iā SiC i ka ʻaʻahu abrasive, ʻoiai i nā noi koi me nā mea abrasive.
ʻOiai he palupalu nā sila kalapona, hāʻawi mau lākou i ke kūpaʻa maikaʻi i ka ʻaʻahu ʻana i nā wahi ʻaʻole e abrasive. ʻO ke ʻano lubrication ponoʻī o ka graphite e kōkua i ka hōʻemi ʻana i ka friction a me ka ʻaʻahu ma waena o nā ʻaoʻao sila.
Ke kū'ē ʻana i ka mahana
Loaʻa i ke kalapona a me ke silicon carbide nā waiwai wela kiʻekiʻe maikaʻi loa. Hiki i nā sila kalapona ke hana maʻamau i nā mahana a hiki i 350°C (662°F), ʻoiai hiki i nā sila silicon carbide ke kū i nā mahana kiʻekiʻe aʻe, pinepine ma mua o 500°C (932°F).
ʻOi aku ke kiʻekiʻe o ka conductivity thermal o ka silicon carbide ma mua o ke kalapona, e ʻae ana i nā sila SiC e hoʻokuʻu i ka wela me ka ʻoi aku ka maikaʻi a mālama i kahi mahana hana haʻahaʻa ma ka interface sealing.
Ke kū'ē kemika
He inert kemika ʻo Silicon carbide a kūpaʻa i ka hoʻouka ʻia mai ka hapa nui o nā waikawa, nā kumu, a me nā mea hoʻoheheʻe. He koho maikaʻi loa ia no ka sila ʻana i nā mea ʻino loa a i ʻole nā mea hoʻonāukiuki.
Hāʻawi pū ke kalapona i ke kūpaʻa kemika maikaʻi, ʻoi aku hoʻi i nā hui organik a me nā waikawa a me nā kumu non-oxidizing. Eia nō naʻe, ʻaʻole paha kūpono no nā wahi oxidizing ikaika a i ʻole nā noi me nā media pH kiʻekiʻe.
Kumukūʻai a me ka Loaʻa
ʻOi aku ka liʻiliʻi o ke kumukūʻai o nā sila mechanical carbon ma mua o nā sila silicon carbide ma muli o ke kumukūʻai haʻahaʻa o nā mea maka a me nā kaʻina hana maʻalahi. Loaʻa nā sila carbon i nā wahi ākea a hiki ke hana ʻia i nā ʻano papa like ʻole a me nā hoʻonohonoho.
ʻOi aku ka kūikawā o nā sila carbide Silicon a loaʻa pinepine i ke kumukūʻai kiʻekiʻe. Pono ka hana ʻana o nā ʻāpana SiC kiʻekiʻe i nā ʻenehana hana holomua a me ka kaohi maikaʻi koʻikoʻi, e kōkua ana i ka hoʻonui ʻia o ke kumukūʻai.
I ka manawa hea e hoʻohana ai i ka sila kalapona
He kūpono nā helehelena sila kalapona no nā noi e pili ana i nā kaomi a me nā mahana haʻahaʻa a waena. Hoʻohana pinepine ʻia lākou i nā pamu wai, nā mea hui, a me nā mea hoʻonāukiuki kahi ʻaʻole i abrasive a corrosive paha ka mea sila. He kūpono nō hoʻi nā sila kalapona no ka sila ʻana i nā wai me nā waiwai lubricating maikaʻi ʻole, ʻoiai ʻo ka mea kalapona ponoʻī e hāʻawi i ka lubrication.
I nā noi me nā pōʻaiapuni hoʻomaka-hoʻōki pinepine a i ʻole kahi e neʻe ai ke koʻokoʻo i ke axial, hiki i nā ʻaoʻao sila kalapona ke hoʻokō i kēia mau kūlana ma muli o ko lākou mau waiwai lubrication ponoʻī a me ka hiki ke kūlike i nā ʻano hewa iki ma ka ʻili pili.
I ka manawa hea e hoʻohana ai i ka sila Silicon Carbide
ʻOi aku ka makemake ʻia o nā helehelena sila silicone carbide i nā noi e pili ana i nā kaomi kiʻekiʻe, nā mahana, a me nā mea abrasive a corrosive paha. Hoʻohana pinepine ʻia lākou i nā kaʻina hana ʻoihana koʻikoʻi, 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 ke sila ʻana i nā wai maʻemaʻe kiʻekiʻe, ʻoiai ʻaʻole lākou e haumia i ka media e sila ʻia ana. I nā noi kahi i loaʻa ai i nā waiwai lubricating maikaʻi ʻole o ka media sila, ʻo ke koina haʻahaʻa o ka friction a me ke kū'ē ʻana i ka ʻaʻahu o SiC e lilo ia i koho maikaʻi loa.
Ke hoʻopilikia pinepine ʻia ka sila mechanical e nā loli pinepine o ka mahana a i ʻole nā haʻalulu wela, kōkua ke alakaʻi wela kiʻekiʻe o SiC a me ke kūpaʻa dimensional i ka mālama ʻana i ka hana sila a me ke ola lōʻihi. Eia kekahi, kūpono nā sila SiC no nā noi e pono ai ke ola lawelawe lōʻihi a me ka mālama liʻiliʻi ma muli o ko lākou kūpaʻa kūikawā a me ke kūpaʻa i ka ʻaʻahu.
Nā nīnau i nīnau pinepine ʻia
ʻO wai ka mea sila mechanical i hoʻohana nui ʻia?
Hoʻohana nui ʻia ke kalapona i nā sila mechanical ma muli o kona kumukūʻai haʻahaʻa a me ka hana kūpono i nā noi he nui.
Hiki ke hoʻohana ʻia nā sila kalapona a me ka silicon carbide me ke ʻano like ʻole?
I kekahi mau hihia, ʻae, akā hilinaʻi ia i nā koi noi kikoʻī, e like me ka mahana, ke kaomi, a me ka launa pū ʻana o ka wai.
I ka hopena
I ke koho ʻana ma waena o nā sila mechanical carbon a me silicon carbide, e noʻonoʻo i nā koi noi kikoʻī. Hāʻawi ka Silicon carbide i ka paʻakikī kiʻekiʻe a me ke kūpaʻa kemika, ʻoiai ʻo ke kalapona e hāʻawi i nā hiki ke holo maloʻo maikaʻi.
