I ka ʻoihana hou, ke hoʻonui ʻia nei ka waiwai o nā mea hana pono, pili i ke kaiapuni, a paʻa. ʻO nā keramika microporous Silicon carbide, ma ke ʻano he mea porous hana kiʻekiʻe, ke pāʻani nei i kahi hana koʻikoʻi i nā kahua e like me ka kānana wela kiʻekiʻe, ka palekana o ke kaiapuni, a me ka ʻenekinia kemika pololei ma muli o ko lākou mau pono hana kūikawā.
1, He aha ka silicon carbide microporous ceramic?
Kalaka silika (SiC)he hui i haku ʻia me ka silicon a me ke kalapona, nona ka paʻakikī kiʻekiʻe loa, ke kūpaʻa wela kiʻekiʻe, a me ke kūpaʻa i ka pala, a ua kapa ʻia ʻo "daimana ʻoihana". ʻO nā keramika micro porous nā mea i piha i nā pores liʻiliʻi i loko, e hāʻawi ana iā lākou i nā waiwai kānana maikaʻi loa, adsorption, a me ka breathability.
Hoʻohui nā keramika microporous Silicon carbide i nā waiwai maikaʻi loa o ka silicon carbide me nā ʻano o ke ʻano microporous, hiki ke mālama i ke kūpaʻa i nā wahi koʻikoʻi a hoʻokō i ka kānana kūpono a me ka hoʻokaʻawale ʻana o nā kinoea a i ʻole nā wai, e lilo ana lākou i mea hana maʻalahi i ke kahua ʻoihana.
2, No ke aha i makemake nui ʻia ai nā keramika microporous silicon carbide?
1. Ke kūpaʻa wela kiʻekiʻe, e like me ka paʻa o ka pōhaku
He nui nā mea i maʻalahi i ka deformation a i ʻole ka hāʻule ʻana i nā mahana kiʻekiʻe, ʻoiai hiki i nā keramika microporous silicon carbide ke hana paʻa i nā wahi ma luna o 1200 ℃ no ka manawa lōʻihi me ka ʻole o ka hoʻopilikia ʻana i kā lākou hana ma muli o nā mahana kiʻekiʻe. ʻO kēia ka mea e lilo ai i koho kūpono no ka mālama ʻana i ke kinoea flue wela kiʻekiʻe i nā ʻoihana e like me ka metallurgy a me ka mana.
2. Kānana pololei a me ka hoʻokaʻawale pono
Ma ka hoʻomalu pono ʻana i ka nui o nā micropores, hiki i nā keramika microporous silicon carbide ke kāohi i nā ʻāpana liʻiliʻi a me nā mea pae molekala. I ka hana kemika, hiki iā ia ke hoʻokaʻawale pono i nā mea hoʻoulu; Ma ke kahua o ka palekana o ke kaiapuni, hiki iā ia ke hopu i ka lepo ʻino i loko o ke kinoea ʻōpala ʻoihana a kōkua i ka hana ʻōmaʻomaʻo.
3. Paʻa a hoʻemi i nā kumukūʻai mālama
He ikaika loa ka pale ʻana o ka mea silicon carbide i ka ʻaʻahu a me ke kūʻē ʻana i ka haʻalulu wela. ʻOiai i nā loli pinepine o ke anu a me ka wela a i ʻole nā wahi erosion kiʻekiʻe, hiki i nā keramika microporous silicon carbide ke mālama i ke kūpaʻa, e hōʻemi nui ana i ka pinepine o ka hoʻololi ʻana i nā lako a me ka hoʻohaʻahaʻa ʻana i nā kumukūʻai hana ʻoihana.
3, Nā hiʻohiʻona noi o nā keramika microporous silicon carbide
ʻO ka hoʻomaʻemaʻe kinoea wela kiʻekiʻe: e like me ka hoʻoheheʻe ʻana i ka metala, ka puhi ʻana i nā ʻōpala, a pēlā aku, hiki ke hopu pono i nā mea particulate i loko o ke kinoea flue wela kiʻekiʻe a hoʻihoʻi i ka ikehu wela.
Kemika kikoʻī a me ka catalysis: Ma ke ʻano he mea lawe catalyst, hoʻomaikaʻi ia i ka pono o ka hopena a hiki ke kū i nā ʻano ʻino e like me nā waikawa ikaika a me nā kumu.
Ma ke kahua o ka ikehu hou, hāʻawi ʻia ke kākoʻo hoʻolaha kinoea paʻa i nā kaʻina hana e like me ka hoʻomākaukau ʻana i ka ikehu hydrogen a me ka sintering mea pila.
Ka mālama ʻana i ka wai o ke kaiapuni: Ma o ka hoʻololi ʻana i ka ʻili, hiki ke hoʻohana ʻia no ka mālama ʻana i ka wai ʻino ʻaila, ka adsorption metala kaumaha, a me nā mea ʻē aʻe, e kōkua i ka hana maʻemaʻe.
4. Ke kuhikuhi hoʻomohala e hiki mai ana
Me ka holomua o ka ʻenehana ʻoihana a me ka hoʻonui ʻia ʻana o ke koi no ka palekana o ke kaiapuni, ke ulu nei nā keramika microporous silicon carbide i ka pololei a me ka naʻauao kiʻekiʻe. No ka laʻana, ka hoʻomaikaʻi ʻana i kāna hana ma o ka ʻenehana uhi composite, a i ʻole ka hoʻohui ʻana me nā ʻōnaehana nānā naʻauao e hoʻokō i ka mana manawa maoli. I ka wā e hiki mai ana, manaʻo ʻia e ʻālohilohi i nā kahua kiʻekiʻe e like me nā semiconductors a me ka biomedicine.
hopena
ʻOiai ke ʻano maʻamau o nā keramika microporous silicon carbide, he kuleana koʻikoʻi ko lākou i ka hana ʻoihana a me ka palekana o ke kaiapuni. Mālama mālie ia i ka maʻemaʻe a me ka pono o ka hana ʻoihana me ka hana paʻa, ka hiki ke kānana pono, a me ke kūpaʻa lōʻihi. I ka wā e hiki mai ana, me ka hana hou o ka ʻenehana, e hoʻomau ia i ka hāʻawi ʻana i ka hoʻomaikaʻi ʻana i ka ʻoihana a me ka hoʻomohala ʻōmaʻomaʻo.
