ʻO ka Alumina Tabular no ka Refractory Dry Ramming Mass Sintered Tabular Alumina no nā mea maka refractory
Ka Wehewehe ʻana o ka Alumina Tabular Sintered
ʻO ke korundum papa ʻaina, ʻike ʻia hoʻi ʻoalumina papa sintered, he ʻano maʻemaʻe kiʻekiʻe o ka alumina (Al2O3) i hana kūikawā ʻia e loaʻa kahiʻano papa kuhikuhi kūikawā, a pālahalaha pahaHana ʻia ia ma ka sintering (hoʻomehana ʻana me ka ʻole o ka hoʻoheheʻe ʻana) i ka pauka alumina kiʻekiʻe ma nā mahana ma luna o 1900°C, e hoʻoulu ana i nā ʻāpana alumina e ulu a hana i nā kristal nui, pālahalaha, e like me ka pā.

| HoʻohanaHoʻohana nui ʻia ka corundum tabular i nā mea refractory hana kiʻekiʻe ma nā kahua okila, hoʻolei ʻana, petrochemicals, nā piliki hanu, nā uhi ladle, nā mea i hoʻoheheʻe ʻia, nā ʻāpana i hana mua ʻia, nā keramika a me nā mahina ʻē aʻeHe mea maka refractory synthetic maikaʻi loa ia. Hoʻohana ʻia ka corundum tabular ma ke ʻano heʻAla hoʻohuihui kūpaʻahiki ke hoʻohana ʻia me ka spinel, ka alumina i hoʻāla ʻia i ka calcined a me nā mea hoʻopaʻa e like me ka sima, ka pālolo a i ʻole ka resin. ʻO nā piliki corundum maʻemaʻe kiʻekiʻe i hoʻomākaukau ʻia he haʻahaʻa ka haumia (e like me SiO2), ka nui o ka nui a me nā waiwai thermodynamic maikaʻi, e hana ana i nā piliki corundum. Kūpaʻa nā piliki i ka pōʻino thermal, kemika a me ke kūkulu ʻana i hoʻokumu ʻia e ka hana o nā gasifiers a me nā umu ʻoihana ʻē aʻe. | ||
