ʻO ka pōmaikaʻi o ka fiber ceramic refractory i ka umu ahi 3

E hoʻomau mākou i kēia pilikia e hoʻolauna i nā pono o ka fiber ceramic refractory.

ʻAʻohe pono no ka umu hoʻomaʻamaʻa a hoʻomaloʻo ma hope o ke kūkulu ʻana
Inā he mau brick refractory a me nā castable refractory, pono e hoʻomaloʻo ʻia ka umu ahi a preheated no kekahi manawa e like me ke koi. A ʻoi aku ka lōʻihi o ka manawa maloʻo no ka refractory castable, maʻamau 4-7 mau lā, e hōʻemi ana i ka helu hoʻohana o ka umu. Inā hoʻohana ka umu ahi i ka hoʻolālā ʻana o ka fiber lining, ʻaʻole i kaupalena ʻia e nā mea metala ʻē aʻe, hiki ke hoʻonui koke ʻia ka mahana o ka umu i ka wela hana ma hope o ke kūkulu ʻana. ʻAʻole kēia e hoʻomaikaʻi wale i ka nui o ka hoʻohana ʻana i nā umu ahi, akā e hōʻemi ana i ka hoʻohana ʻana i ka wahie hana ʻole.
Haʻahaʻa haʻahaʻa thermal conductivity
ʻO ka fiber ceramic refractory kahi hui pū me ke anawaena o 3-5um. Nui nā puka i loko o ka masonry a haʻahaʻa loa ka conductivity thermal. Eia nō naʻe, ma nā ʻokoʻa like ʻole, ʻo ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa e pili ana i ka nui o ka nui, a me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka puʻupuʻu puʻupuʻu e hoʻonui ʻia me ka piʻi ʻana o ka mahana. Wahi a ka ʻike o ka hoʻohana ʻana i ka umu hoʻoheheʻe ʻana o ka fiber i nā makahiki i hala iho nei, ʻoi aku ka maikaʻi i ka wā e hoʻomalu ʻia ai ka puʻupuʻu nui ma 200 ~ 220 kg / m3.
Loaʻa iā ia ke kūpaʻa kemika maikaʻi a me ke kūʻē ʻana i ka ea erosion:
ʻO ka waikawa phosphoric wale nō, ka waika hydrofluoric a me ka alkali wela hiki ke corrodefiber ceramic refractory. Paʻa ka fiber ceramic refractory i nā media corrosive ʻē aʻe.
