ʻO nā pākeke fiber ceramic nā mea hoʻokalakupua kaulana i ʻike ʻia no ko lākou mau waiwai wela. Hoʻohana nui ʻia lākou i nā ʻoihana like ʻole, me ka aerospace, ka mana hana, a me ka hana ʻana, ma muli o ko lākou hiki ke kiʻekiʻe. ʻO kekahi o nā mea koʻikoʻi e kōkua i kā lākou hopena ʻo kā lākou conductivity thermal haʻahaʻa.
ʻO ka hoʻoili wela he ana ia o ka hiki ke hoʻokele wela. He like ia me ka nui o ka wela e kahe ana ma kahi ʻāpana ʻāpana o kahi mea i loko o ka ʻāpana manawa o kēlā me kēia ʻokoʻa wela. Ma nā huaʻōlelo maʻalahi, hoʻoholo ka conductivity thermal i ka maikaʻi o ka mea hiki ke hoʻololi i ka ikehu wela.
He haʻahaʻa loa ka haʻahaʻa haʻahaʻa o nā pākeke fiber Ceramic, kahi mea makemake i nā noi insulating. ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o kēia mau pākeʻe ke kumu nui ʻia i ke ʻano hana ʻokoʻa o nā fiber ceramic.
Hana ʻia nā fiber Ceramic mai ka hui ʻana o nā alumina a me nā mea silica, nona ka haʻahaʻa haʻahaʻa haʻahaʻa. He lahilahi a māmā kēia mau fiber, me ka ratio kiʻekiʻe, ʻo ia hoʻi, ʻoi aku ko lākou lōʻihi ma mua o ke anawaena. Hiki i kēia hale ke hoʻonui i ka ea a me nā hakahaka i loko o ka pākeʻe, e hana ana i mea pale wela a keakea i ka hoʻoili ʻana o ka wela.
Hiki ke ʻokoʻa ka conductivity thermal o kahi pākeke fiber ceramic ma muli o ke ʻano kikoʻī a me ka hoʻohui ʻana o ka pākeke, a me kona ʻano. ʻO ka maʻamau, ʻo ka conductivity thermal o nā pākeke fiber ceramic mai 0.035 a 0.08 W / m.·K. Hōʻike kēia laulima he maikaʻi nā ʻano hoʻokaʻawale ʻana o nā pākeke fiber ceramic, no ka mea, he haʻahaʻa haʻahaʻa loa ko lākou conductivity wela i hoʻohālikelike ʻia me nā mea hoʻolale maʻamau e like me ka fiberglass a i ʻole ka huluhulu pōhaku.
Ka haahaa thermal conductivity opākeke fiber seramikahāʻawi i nā pono he nui i nā noi. ʻO ka mea mua, kōkua ia e hōʻemi i ka nalowale o ka wela a i ʻole ka loaʻa ʻana, e hōʻoia i ka pono o ka ikehu i nā kaʻina hana a me nā hale. Ma ka pale ʻana i ka hoʻololi ʻana o ka wela, kōkua nā pākeke fiber ceramic i ka mālama ʻana i kahi kaiapuni paʻa a hoʻopaʻa ʻia e hōʻemi ana i ka ikehu e pono ai e wela a hoʻomaha paha i kahi ākea.
Hoʻohui ʻia, ʻo ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o nā pākeke seramika e hāʻawi i ko lākou kūpaʻa maikaʻi i nā wela kiʻekiʻe. Hiki i kēia mau pale ke kū i ka mahana a hiki i 2300°F (1260°C) ʻoiai e mālama ana i ko lākou kūpaʻa a me nā waiwai insulating. He mea maikaʻi kēia no nā noi e pili ana i nā kaiapuni wela kiʻekiʻe, e like me nā lining umu a i ʻole kiln.
