He aha ke kūpaʻa wela kiʻekiʻe o ka zirconium i loaʻa i ka pākeke fiber ceramic?

He aha ke kūpaʻa wela kiʻekiʻe o ka zirconium i loaʻa i ka pākeke fiber ceramic? Aia ka Zirconiapākeke fiber seramikaʻO ia kahi mea hana insulation kiʻekiʻe kiʻekiʻe, ʻoi aku ka maikaʻi o ke kūpaʻa kiʻekiʻe ma mua o nā fiber seramika maʻamau (e like me nā fibers maʻamau a i ʻole ka maʻemaʻe kiʻekiʻe), ma muli o ka hoʻohui ʻana o ka zirconia (ZrO ₂), e hoʻomaikaʻi maikaʻi ana i ka paʻa o ke ʻano a me ke kū'ē ʻana i ka hoʻololi ʻana o ke aniani kristal i nā wela kiʻekiʻe.

Aia ka Zirconiapākeke fiber seramikahe mea hoʻopololei maʻalahi me ka papa mua o ke kū'ē wela kiʻekiʻe. ʻO ka hoʻohui ʻana o ka zirconia e loaʻa i kahi kaulike ma waena o ke kiʻekiʻe kiʻekiʻe creep kū'ē a me ka haʻahaʻa thermal conductivity. Ma nā kūlana hana ma lalo o 1300 ℃, ʻoi aku ka maikaʻi o kāna hana holoʻokoʻa (ka maikaʻi o ka insulation, kūpaʻa, a me ke ola lawelawe) ma mua o ka hapa nui o nā fibers refractory kuʻuna, e lilo ia i hoʻokahi o nā hopena i makemake ʻia no nā kaiapuni wela kiʻekiʻe. Ma ke koho maoli ʻana, pono e hoʻokō ʻia kahi loiloi piha e pili ana i ka pihi wela kikoʻī, ka ea lewa, a me ka waihona kālā.

• Haʻahaʻa thermal conductivity:e pili ana i 0.22 W /(m · K) ma 1000 ℃, me ka hana insulation kiʻekiʻe;
• Ka ikaika tensile kiʻekiʻe:≥ 21 MPa, ʻaʻole hiki ke haehae, ʻoi aku ka lōʻihi i ka wā o ke kūkulu ʻana a me ka hoʻohana ʻana;
• ʻO ke kūpaʻa wela maikaʻi a me ke kūpaʻa haʻalulu wela:ʻaʻole maʻalahi ka māwae a pulverize ma hope o ka piʻi pinepine ʻana o ka mahana a hāʻule;
• Paʻa kemika maikaʻi:kūpono no ka neutral a nāwaliwali oxidizing/hōʻemi i nā ea, akā ʻaʻole kūʻē i nā ʻakika ikaika a me nā kumu, e koi ana i kahi papa pale.
• Launa pale wela ākea:Hiki ke piʻi ka mahana hana lōʻihi ma kahi o 1350 ℃, a hiki ke kiʻekiʻe ka mahana hoʻohālikelike e like me 1430 ℃, hiki ke hoʻokō i nā pono o nā ʻano wela wela.
• Nā kahua ākea ākea:Ma muli o kona maikaʻi kiʻekiʻe wela kū'ē, zirconium i loko o ka ceramic fiber blanket ua hoʻohana nui 'ia i loko o kiʻekiʻe-mahana kahua e like me ka kiln lining, boiler insulation, wela lapaʻau wela mana, aniani kiln hale insulation, kapuahi pani puka, flue lining, pipeline insulation, etc. gaskets no nā mea hana hale.
