I loko o ka ʻoihana hou, ʻoi aku ka waiwai o nā mea pono, pili kaiapuni, a me nā mea paʻa. ʻO ka silikoni carbide microporous ceramics, ma ke ʻano he mea porous hana kiʻekiʻe, ke pāʻani nei i kahi kuleana koʻikoʻi i nā kula e like me ka kānana wela kiʻekiʻe, ka mālama ʻana i ke kaiapuni, a me ka ʻenekini kemika pololei ma muli o kā lākou mau pono hana kūʻokoʻa.
1, He aha ka silicon carbide microporous ceramic?
Silika kalapona (SiC)he hui i haku ʻia me ka silikoni a me ke kalapona, nona ka paʻakikī kiʻekiʻe loa, ke kūpaʻa wela kiʻekiʻe, a me ka pale ʻana i ka corrosion, a ua ʻike ʻia ʻo ia ʻo "industrial diamond". ʻO ka micro porous ceramics nā mea i hoʻopiha ʻia me nā pores liʻiliʻi i loko, e hāʻawi iā lākou i ka kānana maikaʻi, adsorption, a me nā waiwai breathability.
Hoʻohui nā silicon carbide microporous ceramics i nā waiwai maikaʻi loa o ka silicon carbide me nā hiʻohiʻona o ka microporous structure, hiki ke hoʻomau i ka paʻa i nā kaiapuni koʻikoʻi a hoʻokō i ka kānana kūpono a me ka hoʻokaʻawale ʻana o nā kinoea a i ʻole nā wai, e hoʻolilo iā lākou i mea hana maʻalahi i ka ʻoihana ʻoihana.
2、 No ke aha i makemake ʻia ai nā seramika microporous silicon carbide?
1. ʻO ke kūpaʻa wela kiʻekiʻe, paʻa e like me ka pōhaku
Hiki i nā mea he nui ke deformation a i ʻole ka hāʻule ʻole i nā wela kiʻekiʻe, ʻoiai hiki i ka silicon carbide microporous ceramics 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 ke kiʻekiʻe wela. ʻO kēia ka mea i koho maikaʻi loa no ka hoʻomaʻamaʻa kinoea flue kiʻekiʻe i nā ʻoihana e like me ka metallurgy a me ka mana.
2. ʻO ka kānana pololei a me ka hoʻokaʻawale kūpono
Ma ke kaohi pono ʻana i ka nui o nā micropores, hiki i ka silicon carbide microporous ceramics ke hoʻopili i nā mea liʻiliʻi a me nā mea pae molekala. I ka hana kemika, hiki iā ia ke hoʻokaʻawale i nā catalysts; Ma ke kahua o ka mālama ʻana i ke kaiapuni, hiki iā ia ke hopu i ka lepo pōʻino i loko o ke kinoea ʻōpala ʻoihana a kōkua i ka hana ʻōmaʻomaʻo.
3. Paʻa a hoʻemi i nā kumukūʻai mālama
ʻO nā mea Silicon carbide ponoʻī he ikaika loa ke pale ʻana i ka ʻaʻahu a me ke kūpaʻa haʻalulu wela. ʻOiai i ka hoʻololi pinepine ʻana i ka wela a i ʻole nā kaiapuni erosion kiʻekiʻe, hiki i ka silicon carbide microporous ceramics ke mālama i ka paʻa, e hōʻemi nui ana i ka hoʻololi ʻana i nā mea hana a me ka hoʻohaʻahaʻa ʻana i nā kumukūʻai hana.
3、 Hoʻohana i nā hiʻohiʻona o ka silicon carbide microporous ceramics
ʻO ka hoʻomaʻemaʻe kinoea wela kiʻekiʻe: e like me ka hoʻoheheʻe ʻana i ka metala, ka ʻōpala ʻōpala, a me nā mea ʻē aʻe, hiki ke hoʻopaʻa maikaʻi i nā mea i loko o ke kinoea wela wela a hoʻihoʻi hou i ka ikehu wela.
Kemika pololei a me ka catalysis: Ma ke ʻano he mea lawe catalyst, hoʻomaikaʻi ia i ka maikaʻi o ka pane ʻana a hiki ke kū i nā kaiapuni paʻakikī e like me nā waikawa ikaika a me nā kumu.
Ma ke kahua o ka ikehu hou, hāʻawi ʻia ke kākoʻo diffusion gas paʻa i nā kaʻina hana e like me ka hoʻomākaukau ʻana i ka ikehu hydrogen a me ka sintering mea pākaukau.
ʻO ka mālama ʻana i ka wai kaiapuni: Ma o ka hoʻololi ʻana i ka ʻili, hiki ke hoʻohana ʻia no ka mālama ʻana i ka wai ʻaila hinu, adsorption metala kaumaha, etc., e kōkua i ka hana maʻemaʻe.
4、 Alakaʻi hoʻomohala e hiki mai ana
Me ka holomua o ka ʻenehana ʻenehana a me ka piʻi nui ʻana o ka noi no ka pale ʻana i ke kaiapuni, ke ulu nei ka silicon carbide microporous ceramics i ke kiʻekiʻe kiʻekiʻe a me ka naʻauao. No ka laʻana, ka hoʻonui ʻana i kāna hana ma o ka ʻenehana uhi hoʻohuihui, a i ʻole ka hoʻohui ʻana me nā ʻōnaehana mākaʻikaʻi naʻauao e hoʻokō i ka mana manawa maoli. I ka wā e hiki mai ana, manaʻo ʻia e ʻālohilohi i nā kula kiʻekiʻe e like me semiconductors a me biomedicine.
hopena
ʻOiai he mea maʻamau ka silicon carbide microporous ceramics, he hana koʻikoʻi lākou i ka hana ʻoihana a me ka pale ʻana i ke kaiapuni. Mālama mālie ʻo ia i ka maʻemaʻe a me ka maikaʻi o ka hana ʻoihana me ka hana paʻa, ka mana kānana maikaʻi, a me ka lōʻihi lōʻihi. I ka wā e hiki mai ana, me ka hoʻomau mau ʻana o ka ʻenehana, e hoʻomau ia i ke kōkua ʻana i ka hoʻonui ʻana i ka ʻoihana a me ka hoʻomohala ʻōmaʻomaʻo.
