• Brown fused alumina

ʻO ke alumina i hoʻohuihui ʻia

Brown jade, ka inoa maʻamau i ʻike ʻia e like me ke one daimana, he kanaka ʻeleʻele i hoʻopaʻa ʻia me ka alumina, carbon material, a me ʻekolu mau mea maka i hoʻoheheʻe ʻia a hoʻemi ʻia i ka umu ahi arc uila, no laila ʻo ia ka inoa.ʻO nā mea kemika nui o ka jade brown he Al2O3, a he 95.00% -97.00% kona maʻiʻo, a aia kekahi mea liʻiliʻi o Fe, Si, Ti, etc. ʻO ka jade brown ka mea abrasive kumu, no ka mea, ʻo kāna hana wili. maikaʻi, ākea ka hoʻohana ʻana, ʻuʻuku, a hoʻohana nui ʻia.

ʻO ka jade brown ka mea nui maka me ka alumini aluminous, coke (anthracite), a he kiʻekiʻe ka wela o ka hoʻoheheʻe ʻana i ka umu ahi arc.He kūpono ia no ka wili metala kiʻekiʻe, e like me ke kila maʻamau., Hiki ke hana i ka hao hao, keleawe paakiki, etc., hiki no hoi ke hana i na refractory holomua.ʻO ka brown grungy nā hiʻohiʻona o ka maʻemaʻe kiʻekiʻe, ka crystallization maikaʻi, ka wai ikaika, ka coefficient hoʻonui uea haʻahaʻa, a me ka pale ʻana i ka corrosion.Me ka nui o nā mea hana pale ahi, loaʻa i ka huahana nā hiʻohiʻona o ka pahū, ʻaʻohe pauka, a me ka haki ʻole i ka noi.ʻO ka mea nui, ʻoi aku ka kiʻekiʻe ma mua o ke kumu kūʻai o ka jasteas brown maʻamau, kahi mea e hoʻohui maikaʻi ai a me ka hoʻopiha ʻana i nā mea refractory brown jade.
