Alumina Bubble ua hana ia ma ka fusing kūikawā kiʻekiʻe maemae alumina.Th e hehee ai ua atomized me ka compressed ea e alakai aku ai i ka poʻe hakahaka. He paʻakikī akā paʻakikī loa e pili ana i kona ikaika ikaika. Hoʻohana ʻia ka pahu alumina i ka hana ʻana i nā refractory insulating māmā kahi e pono ai ka conductivity thermal haʻahaʻa a me nā pono wela kiʻekiʻe. Hoʻohana maikaʻi ʻia ia no nā refractory loose-fill.

Hoʻohana ʻia ʻo Alumina Bubble i ka hana ʻana i nā ractories insulating refr māmā kahi haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me nā waiwai wela kiʻekiʻe ka mea nui e pono ai a no ka hoʻopiha piha ʻana i nā refractories. Hiki ke hoʻohana ʻia ʻo C no ka hana lima lima a i ʻole nā puʻu seramika insulating kiʻekiʻe no ka hoʻolei kālā. Hiki ke hoʻohana ʻia e like me kahi moena i ke kaʻina hana o nā huila wili vitrified a ma ke ʻano he media e kānana ai i nā wai ʻino a hoʻoheheʻe paha.

Hana ʻia ʻo Bubble Alumina mai ka alumina maʻemaʻe kiʻekiʻe i loko o kahi umu ahi arc. I ka hoʻoheheʻe ʻia ʻana, hoʻoheheʻe ʻia ka alumina me ka ea paʻa, kahi e hoʻohua ai i nā pōʻai hollow. ʻO ka helu heheʻe o Bubble Alumina ma kahi o 2100ºC.

Kaʻina hana o ka hana a me ka noi

Hoʻokumu ʻia ʻo Fused Bubble Alumina ma ka puhi ʻana i ka hehee o ka alumina kaʻina Bayer maʻemaʻe kiʻekiʻe i loko o kahi lewa i hoʻomalu ʻia e hana i nā pōʻai ʻā. Ma muli o kona haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i hoʻohui ʻia i ka puʻupuʻu alumina he mea kūpono ia no ka alumina kiʻekiʻe e pili ana i ka Insulating Bricks a me nā castables.
