Ke koho mākou i kahi huahana fiber ceramic, e nīnau mākou i ka mea hana no ka ʻikepili hana nui o ka huahana a hoʻomaopopo i ka waiwai ʻikepili no ke kuhikuhi ʻana i ke koho, akā ʻaʻole maopopo loa ka mea kūʻai aku i ke ʻano o ka waiwai a i ʻole kekahi mea hou. ʻAʻole maopopo nā mea kūʻai i ke ʻano o ka ʻikepili, e nīnau mau iā mākou e pili ana i ke ʻano o ka ʻikepili.I kēia lā 100 nānā iā ʻoe e wehewehe i nā huahana fiber ceramic o kēia ʻike liʻiliʻi, manaʻo wau e kōkua iā ʻoe!
1 ʻO ka ʻokoʻa ma waena o nā mea insulation thermal a me nā mea refractory
ʻO ka ʻōlelo maʻamau, ma lalo o 1570 ℃ ua kapa ʻia ʻo ka insulation material;Ma luna o 1570 ℃ mea refractory mea.ʻO nā mea refractory kuʻuna maʻamau e pili ana i ke ahi ahi kaumaha, castable, a me nā mea ʻē aʻe, ʻo ka nui o ka leo he 1000-2000kg/m3.
ʻO nā mea maikaʻi o ka fiber ceramic he mea maopopo loa, ma lalo o ka manaʻo o ka hana insulation thermal maikaʻi loa, akā maikaʻi nō hoʻi ke kūpaʻa ahi, a no ka mea māmā, hoʻemi i ka ukana o ka umu, hoʻemi nui i ka hoʻonohonoho kuʻuna ma muli o ke kākoʻo o ke kaumaha. nā mea i pau i ka nui o ke kila.
2 uwea wela shrinkage
Papa kuhikuhi no ka loiloi ʻana i ke kūpaʻa wela (wela lawelawe) o nā huahana fiber ceramic.ʻO nā koi i hui pū ʻia o nā huahana ceramic fiber ma lalo o ka hoʻomehana ʻole ʻana i kahi mahana, mālama ʻia ka wela no nā hola 24 o ka laina wela wela e hōʻike ana i ka pale wela o ka fiber ceramic.
ʻO ka mahana ho'āʻo o ka helu shrinkage uea wela ≤3% ʻo ia ka mahana lawelawe mau o nā huahana ceramic fiber.I kēia mahana, hoʻomaloʻo a ulu mālie nā fibers ceramic amorphous, a paʻa a elastic ka waiwai o ka fiber.
Heating uea shrinkage waiwai ≤4% ho'āʻo wela no ka ceramic fiber huahana hoʻohana wela.
3 Ka hoʻoili wela
ʻO ka conductivity thermal kahi ʻano waiwai kino o nā mea, ʻo ia ka helu o ka waiwai insulation thermal o ka fiber ceramic.
Aia i ke ʻano o nā huahana fiber ceramic, ka nui o ka nui, ka mahana, ka lewa umu, ka haʻahaʻa a me nā mea ʻē aʻe.
ʻO ka fiber Ceramic kahi hui o ka fiber paʻa a me ka ea me kahi porosity o 93%.Hoʻopiha ʻia ka nui o ka ea me ka haʻahaʻa haʻahaʻa haʻahaʻa i loko o nā pores, a ua luku ʻia ka ʻōnaehana hoʻomau o nā molekole paʻa, i loaʻa ai ka hana adiabatic maikaʻi loa.A ʻo ka liʻiliʻi o ke anawaena pore, ma ke ala o ke kahe wela e ka fiber paʻa i hoʻokaʻawale ʻia i loko o kahi kūlana pani o ka helu o nā pores, ʻoi aku ka maikaʻi o ka hana insulation thermal o ka fiber ceramic.
4. Ka hopena o ka haku mele
Hoʻoholo pololei ka haku melemele i ka pale wela o ka fiber:
(1) Al2O3, SiO2, ZrO2, Cr2O3 a me nā mea pono ʻē aʻe ≥99%, kiʻekiʻe kiʻekiʻe o ka oxide content, hoʻoholo pololei i ka hana o ka fiber ceramic.
(2) Fe2O3, Na2O, K2O, MgO a me nā mea haumia ʻē aʻe ma lalo o 1%, pili i nā haumia ʻino, alakaʻi pololei i ka deterioration o ka hana ceramic fiber.
