ʻO ka Alumina Tabular no nā mea hoʻoheheʻe maloʻo ʻo Refractory Dry Ramming Mass Sintered Tabular Alumina for Refractory Raw Materials.
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 (hoʻomaʻamaʻa ʻole me ka hoʻoheheʻe ʻana) kiʻekiʻe kiʻekiʻe alumina pauka ma nā mahana ma luna o 1900 ° C, e hoʻoulu ai i nā ʻāpana alumina e ulu 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 maʻemaʻe 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 Kūʻē nā pōhaku i ka wela, kemika a me ka pōʻino i hana ʻia e ka hana ʻana o nā gasifiers a me nā umu ʻoihana ʻē aʻe. | ||
