ʻO nā mea hoʻoheheʻe fiber refractory i hoʻohana ʻia i ke kūkulu ʻana i ka umu ahi 3

ʻO kēia pilikia e hoʻomau mākou i ka hoʻolauna ʻana i nā mea insulation fiber refractory i hoʻohana ʻia i ke kūkulu ʻana i ka umu

1) ka fiber refractory
ʻO ka fiber refractory, i ʻike ʻia ʻo ka fiber ceramic, he ʻano mea ʻole i hana ʻia e ke kanaka, he aniani a i ʻole crystalline phase binary compound i haku ʻia me Al2O3 a me SiO2 ma ke ʻano nui. Ma ke ʻano he mea insulation refractory māmā, hiki iā ia ke mālama i ka ikehu e 15-30% ke hoʻohana ʻia i nā umu ahi. Loaʻa nā hiʻohiʻona maikaʻi o ka fiber Refractory:
(1) Kūleʻa wela kiʻekiʻe. ʻO ka mahana hana o ka alumini silicate refractory fiber he 1200 ° C, a ʻo ka mahana hana o ka fiber refractory kūikawā e like me ke alumina fiber a me ka mullite he kiʻekiʻe e like me 1600-2000 ° C, aʻo ka mahana refractory o nā mea fiber maʻamau e like me ka asbestos a me ka huluhulu pōhaku ma kahi o 650 ° C wale nō.
(2) Hoʻopuʻi wela. He haʻahaʻa loa ka conductivity thermal o ka fiber refractory i ka wela wela, a ʻo ka conductivity thermal o ka alumini silicate refractory fiber maʻamau ma 1000 °C he 1/3 o nā pōhaku lepo māmā, a he liʻiliʻi kona wela wela, ʻoi aku ka maikaʻi o ka insulation wela. Hiki ke ho'emi 'ia ka mānoanoa o ka umu ahi i ho'ohālikelike 'ia me ka ho'ohana 'ana i nā pōhaku lepo māmā.
ʻO ka puke aʻe e hoʻomau mākou i ka hoʻolaunanā mea hoʻokuʻu fiber refractoryhoʻohana ʻia i ke kūkulu ʻana i ka umu ahi. E ʻoluʻolu e hoʻomau!
