He aha ka Honeycomb Ceramics?

I nā makahiki i hala iho nei, ua ulu nui ke koi no nā mea hana pili i ke kaiapuni a me ka pono ma nā ʻoihana like ʻole. ʻO kekahi mea hana hou i hopu i ka manaʻo o nā mea noiʻi a me nā ʻenekinia, ʻo ia nā keramika honeycomb. He ʻano honeycomb kūikawā kēia mea, e hāʻawi ana i nā pono he nui a me ka versatility i kāna mau noi. Hāʻawi ka ʻatikala ma lalo nei i kahi ʻimi hohonu o nā keramika honeycomb, e kūkākūkā ana i ko lākou ʻano, nā ʻano, ka haku mele kemika, ke kaʻina hana hoʻomākaukau, a me ka nui o nā noi i nā ʻoihana e like me ke kaʻa, kemika, ka mana uila, a me nā mea hou aku. Ma ka hoʻomaopopo ʻana i ka hiki o nā keramika honeycomb, hiki iā mākou ke hoʻohana maikaʻi i ko lākou mau pono a hoʻomākaukau i ke ala no kahi wā e hiki mai ana e hoʻomau a pono ma nā ʻāpana like ʻole.

1、He aha ka Honeycomb Ceramics

He huahana keramika hou nā keramika meli me kahi ʻano e like me ke ʻano o ka meli. Ua hoʻohana mua ʻia ia i ka hoʻomaʻemaʻe ʻana i ka ʻōpala kaʻa liʻiliʻi, a i kēia manawa ua hoʻohana nui ʻia ia i nā ʻoihana e like me ke kemika, ka mana uila, ka metallurgy, ka petroleum, nā mea uila, a me nā mīkini, me nā noi ākea a me nā manaʻolana hoʻohiki. Hiki ke hana ʻia nā keramika meli mai nā ʻano mea like ʻole, ʻo ia hoʻi me ka cordierite, mullite, alumina titanate, kalapona i hoʻāla ʻia, silicon carbide, alumina i hoʻāla ʻia, zirconia, silicon nitride, a me nā matrices composite.

2、Nā ʻano keramika meli

Hiki ke hoʻokaʻawale ʻia nā keramika meli i ʻehā mau ʻāpana nui e pili ana i kā lākou hoʻohana: nā kino mālama wela, nā mea hoʻopili, nā mea lawe catalyst, a me nā mea kānana.

ʻOi aku ka nui o ka wela o nā kino mālama wela o ka melaki meli ma mua o 1000 kJ/kg, me ka mahana hana kiʻekiʻe loa ma ka liʻiliʻi he 1700℃. Hiki iā lākou ke mālama i ka wahie ma mua o 40% i loko o nā umu e like me nā umu hoʻomehana, nā umu hoʻomoʻa, nā umu homogenizing, a me nā umu haki, hoʻonui i ka hana ma mua o 15%, a hoʻohaʻahaʻa i ka mahana o ka uahi i hoʻokuʻu ʻia i lalo o 150℃.

ʻOi aku ka nui o ka ʻili o nā mea hoʻopili keramika meli a ʻoi aku ka ikaika ma mua o nā mea hoʻopili ʻē aʻe, e hopena ana i ka hoʻolaha like ʻana o ke kinoea-wai, ka emi ʻana o ke kūpaʻa o ka moena, ka hana maikaʻi, a me ke ola lawelawe lōʻihi. Hoʻohana ʻia lākou ma ke ʻano he mau mea hoʻopili i nā ʻoihana petrochemical, lāʻau lapaʻau, a me nā kemika maikaʻi me ka holomua nui.

He mea maikaʻi loa nā keramika meli ke hoʻohana ʻia ma ke ʻano he mau mea hoʻoulu. Ma ka hoʻohana ʻana i nā mea keramika meli e like me nā mea lawe a me ka hoʻohana ʻana i nā mea uhi kū hoʻokahi, ua hoʻomākaukau ʻia lākou me nā metala makamae, nā metala honua laha ʻole, a me nā metala hoʻololi, e hopena ana i ka hana catalytic kiʻekiʻe, ke kūpaʻa wela maikaʻi loa, ke ola lawelawe lōʻihi, a me ka ikaika kiʻekiʻe.

3、Nā ʻano o nā keramika meli

ʻO ka ikaika kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa i ka pala, a me ke kūpaʻa ʻana i ka ʻaʻahu e kūpono ai nā keramika meli no nā ʻano kahua palekana kaiapuni like ʻole. ʻO kekahi mau waiwai:

ʻĀpana kiʻekiʻe

ʻO ke porosity kiʻekiʻe a me ke anawaena pore like

Haʻahaʻa kaomi haʻahaʻa

Ka helu hoʻonui wela haʻahaʻa

Ke kū'ē nei i ka haʻalulu wela kiʻekiʻe a me ka haʻalulu

Ke kūpaʻa kiʻekiʻe i ka pala kemika (anti-acid ≥99.8%)

Ikaika compressive kiʻekiʻe

4、Ka Hoʻohui Kemika o nā Seramika Honeycomb

Hana ʻia nā waihona meli seramika mai kaolin, talc, pauka alumini, a me ka pālolo. I kēia mau lā, ma ka hoʻohui ʻana i ka zeolite a me nā mea paʻakikī ʻē aʻe, hiki ke loaʻa nā waiwai ʻē aʻe no kēia mau mea.

Nā mea hana hale (MOC):

ʻO Cordierite

Ka hoʻohuihui kemika Cordierite:

ʻAlumina: 35.2 ± 1.5%

Silika: 50.9±1.5%

Magnesia: 13.9 ± 1.5%

5、Kaʻina Hana Hoʻomākaukau o nā Seramika Honeycomb

Hiki ke hana ʻia nā keramika meli mai nā ʻano mea like ʻole. ʻO nā mea nui e komo pū ana me ka cordierite, mullite, alumini titanate, kalapona i hoʻāla ʻia, silicon carbide, alumina i hoʻāla ʻia, zirconia, silicon nitride, a me nā substrates i hui pū ʻia o cordierite-mullite a me cordierite-aluminum titanate.

Ma hope o ke kālai ʻana i ka pauka kalapona i hoʻāla ʻia a i ʻole nā ​​granules i loko o kahi ʻano keramika meli, ua hoʻomaikaʻi nui ʻia ka hiki ke hoʻomaʻemaʻe a me ka mālama ʻana i ka wai ʻino, ʻoi aku hoʻi i ka ʻoihana lāʻau lapaʻau no ka wehe ʻana i nā haumia, ka maloʻo ʻana, a me ka decolorization o nā antibiotics, hormones, vitamins, nucleic acid injections, a me nā ʻano inikini a me nā lāʻau lapaʻau like ʻole. I ka wā e hana ʻia ai nā keramika meli ma o ka extrusion, pono e hoʻohui ʻia nā mea hoʻohui like ʻole i nā mea maka nui e hoʻonui i ka plasticity a me ka fluidity o ke kino lepo. ʻO kēia mau mea hoʻohui nui e pili ana i nā mea hoʻopaʻa, nā plasticizers, nā deflocculants, nā lubricants, a me nā mea hoʻomaʻū. Eia kekahi, aia kekahi mau mea hoʻopaʻa wai, nā mea chelating, nā mea antistatic, nā mea pale colloidal, a me nā surfactants. I kēia manawa, hoʻohana nui ʻia ka starch, carboxymethyl cellulose, a me ka polyvinyl alcohol ma ke ʻano he mea hoʻopaʻa, ka ʻaila tung a me ka stearic acid ma ke ʻano he lubricants, a me ka glycerin ma ke ʻano he plasticizer.

6、Nā noi o nā keramika meli

Nā mea lawe mea hoʻoulu

Ke hoʻohana ʻia ma ke ʻano he mea lawe catalyst, hoʻohana nui ʻia nā keramika honeycomb i ka hoʻomaʻemaʻe ʻana i ka hoʻopau ʻana i nā kaʻa, ka denitration gas flue boiler (NOx), ka wehe ʻana i ke ʻala o ka hoʻopau ʻoihana, a me ka hoʻopau ʻana i nā kinoea ʻawahia a me nā mea ʻino. ʻO nā mea lawe catalyst keramika honeycomb i hoʻohana ʻia i ka hoʻomaʻemaʻe ʻana i nā hoʻopau kaʻa he mau keramika honeycomb cordierite i uhi ʻia me γ-Al2O3.

Nā Lako Uila Refractory

ʻOi aku ka māmā o nā lako hale umu honeycomb i hoʻopili ʻia he 60%-75% ma mua o nā lako umu kuʻuna, e ʻae ana i ka hoʻoili wela wikiwiki a me ke ahi wikiwiki. ʻO ka hoʻohana ʻana i nā keramika honeycomb ma ke ʻano he kākoʻo no ke ahi ʻana i nā ferrites a i ʻole nā ​​​​ceramic uila ʻē aʻe e kōkua i ka hoʻomaikaʻi ʻana i ka hana o nā huahana.

Nā Kānana Kahe o ka Pā

Hiki ke hoʻohana ʻia nā keramika honeycomb porous me ka paia lahilahi e kānana a hoʻomaʻemaʻe i nā ʻāpana kalapona i loko o nā kinoea hoʻopau o ka mīkini diesel (ma kahi o 500 ℃).

7、I ka hopena, he mau mea hana like ʻole a me nā mea hou nā keramika meli me kahi ʻano meli kū hoʻokahi e hāʻawi ana i nā pono like ʻole. Hoʻohana ʻia lākou i nā ʻano ʻoihana like ʻole, me ke kaʻa, kemika, ka mana uila, ka metallurgy, ka petroleum, nā mea uila, a me nā mīkini. ʻO ko lākou mau waiwai maikaʻi loa, e like me ka ikaika kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa i ka pala, a me ke kūpaʻa ʻana i ka ʻaʻahu, e kūpono iā lākou no nā noi like ʻole, me nā kino mālama wela, nā mea hoʻopaʻa, nā mea lawe catalyst, a me nā mea kānana. Me ka holomua mau ʻana i ka ʻepekema mea a me ka ulu ʻana o ke koi no nā mea aloha i ke kaiapuni a me ka pono, e pāʻani paha nā keramika meli i kahi kuleana koʻikoʻi i nā ʻoihana like ʻole, e hoʻohiki ana i kahi wā e hiki mai ana no kā lākou hoʻomohala ʻana a me nā noi.
