ʻO ka alumina papa no ka mea hoʻomaʻamaʻa maloʻo Ramming Mass Sintered Tabular Alumina no nā lako maka.
Hōʻike ʻia ʻo Tabular Alumina Sintered
ʻO ka corundum tabular, i ʻike ʻia ʻoalumina tabular sintered, he ʻano alumina maʻemaʻe kiʻekiʻe (Al2O3) i hana pono ʻia e loaʻa i kahiʻano papa kūʻokoʻa, a pālahalaha paha.Hana ʻia ia e ka sintering (hoʻoheheʻe ʻole me ka hoʻoheheʻe ʻana) kiʻekiʻe kiʻekiʻe alumina pauka ma nā mahana ma luna o 1900 ° C, e ulu ai nā ʻāpana alumina a hana i nā kristal nui, pālahalaha, e like me ka pā.

| Hoʻohana: Hoʻohana nui ʻia ʻo Tabular corundum i nā mea refractory hana kiʻekiʻe ma nā kula okila, hoolei, petrochemicals, breathable bricks, ladle linings, castables, prefabricated parts, ceramics and other fields.He mea maikaʻi synthetic refractory maka.Hoʻohana ʻia ʻo Tabular corundum e like meHōʻuluʻulu refractoryhiki ke hoʻohana pū me ka spinel, calcined activated alumina a me nā mea hoʻopaʻa e like me ka sima, ka pālolo a i ʻole resin.ʻO nā pōhaku lepo corundum hoʻomaʻemaʻe kiʻekiʻe i hoʻomākaukau ʻia he haʻahaʻa haʻahaʻa haʻahaʻa (e like me SiO2), kiʻekiʻe ka nui o ka nui a me nā waiwai thermodynamic maikaʻi, ka hana ʻana i nā pōhaku corundum Ua kū kūʻē nā pōhaku i ka wela, kemika a me ka pōʻino i hoʻokumu ʻia e ka hana o nā gasifiers a me nā kapuahi ʻoihana ʻē aʻe. | ||
