E kamaʻilio e pili ana i ka ʻeleʻele Honeycomb

Hōʻike huahana:

ʻO nā ʻano melemele he ʻano huahana seramika hou me kahi ʻano like me ka honeycomb. Hana ʻia ia me nā mea maka e like me kaolin, talc, alumini pauka, a me ka pālolo. Loaʻa iā ia nā ʻano like ʻole i haku ʻia me nā lua like ʻole. ʻO ka helu kiʻekiʻe o nā puka i hiki i ka 120-140 no ka square centimeter, ʻo ka nui o ka 0.3-0.6 grams no ka cubic centimeter, a ʻo ka nui o ka absorption wai e like me 20%. Hoʻonui nui kēia ʻano porous i ka ʻili o ka mea lawe a hoʻomaikaʻi i ke kūpaʻa haʻalulu wela. ʻO nā puka mesh o nā seramika honeycomb he triangular a me ka huinahā, ma waena o nā puka triangular i ʻoi aku ka maikaʻi o ka lawe ʻana ma mua o nā lua square a me nā lua hou aʻe, ʻo ia ka mea koʻikoʻi ma ke ʻano he catalytic carrier. Me ka hoʻonui ʻana o ka nui o nā lua ma kēlā me kēia ʻāpana a me ka emi ʻana o ka mānoanoa o ka pā pore lawe, ua hoʻomaikaʻi ʻia ke kūpaʻa haʻalulu wela o ka mea lawe seramika, a ua hoʻonui pū ʻia ka mahana o ka pōʻino wela. No laila, pono e hoʻemi ka honeycomb ceramics i ka hoʻonui ʻana a hoʻonui i ka nui o nā lua i kēlā me kēia ʻāpana.

Nā mea nui:

Cordierite, mullite, alumini porcelain, alumina kiʻekiʻe, corundum, etc.

noi huahana:

1) Ma ke ʻano he kino mālama wela: ʻO ka nui o ka wela o ka honeycomb ceramic heat storage body ma mua o 1000kJ / kg, a ʻo ka mahana hana kiʻekiʻe o ka huahana ʻo ≥1700 ℃. Hiki iā ia ke ho'ōla ma mua o 40% o ka wahie i nā kapuahi hoʻomehana, nā mea hoʻoheheʻe, nā kapuahi hoʻoheheʻe, nā kapuahi a me nā kiln ʻē aʻe, e hoʻonui i ka hana ma mua o 15%, a ʻoi aku ka haʻahaʻa o ka wela kinoea ma mua o 150 ℃.

2) Ma ke ʻano he mea hoʻopihapiha: Loaʻa i nā mea hoʻopihapiha honeycomb ceramic nā pōmaikaʻi e like me ka ʻāpana kikoʻī kikoʻī nui a me ka ikaika ʻoi aku ka maikaʻi ma mua o nā ʻano hoʻopihapiha. Hiki iā lākou ke hana i ka hāʻawi ʻana i ke kinoea i ʻoi aku ka lole, hoʻemi i ka pale moe, loaʻa nā hopena maikaʻi aʻe, a hoʻonui i ke ola lawelawe. He mea maikaʻi loa lākou e like me nā mea hoʻopiha i ka petrochemical, pharmaceutical a me nā ʻoihana kemika maikaʻi.

3) Ma ke ʻano he mea lawe catalyst: ʻOi aku ka maikaʻi o ka honeycomb ceramics i nā catalysts. Ke hoʻohana nei i nā mea honeycomb ceramic e like me nā mea lawe, me ka hoʻohana ʻana i nā mea hoʻonaninani kūʻokoʻa, a hoʻomākaukau ʻia me nā metala makamae, nā metala honua ʻole a me nā metala hoʻololi, loaʻa iā lākou nā pōmaikaʻi o ka hana catalytic kiʻekiʻe, ke kūpaʻa wela maikaʻi, ke ola lōʻihi, ka ikaika kiʻekiʻe, etc.

4) E like me ka mea kānana: maikaʻi kemika kūpaʻa, kū'ē i ka waika, alkali a me ka organic solvents; kū'ē maikaʻi loa i ka hoʻomehana wikiwiki a me ka hoʻomaha, hiki ke kiʻekiʻe ka mahana hana e like me 1000 ℃; nā waiwai antibacterial maikaʻi, ʻaʻole hiki ke hoʻohaʻahaʻa ʻia e ka maʻi bacteria, ʻaʻole maʻalahi ke kāohi ʻia a maʻalahi hoʻi e hana hou; paʻa paʻa paʻa, hāʻawi ʻia ka nui o ka pore, permeability kiʻekiʻe; ʻaʻohe mea ʻawaʻawa, kūpono loa no ka meaʻai a me ka hana lāʻau.
