Hoʻolālā kūikawā ʻia nā alumina reactive no ka hana ʻana i nā refractory hana kiʻekiʻe kahi i wehewehe ʻia ai ka paʻi ʻāpana, rheology a me nā hiʻohiʻona hoʻonohonoho kūlike e like me nā waiwai kino o ka huahana hope. Hoʻopili piha ʻia nā alumina reactive a hiki i nā kristal mua (hoʻokahi) e nā kaʻina wili maikaʻi loa. ʻO ka awelika nui o nā ʻāpana, D50, o nā alumina reactive mono-modal, no laila ua aneane like me ke anawaena o kā lākou mau kristal hoʻokahi. ʻO ka hui pū ʻana o nā alumina reactive me nā mea matrix ʻē aʻe, e like me ka tabular alumina 20μm a i ʻole spinel 20μm, e ʻae i ka mana o ka puʻupuʻu nui o ka particle e hoʻokō i ka rheology hoʻokomo i makemake ʻia.

ʻO nā alumina reactive mai ka sub-micron a hiki i ka 3 micron ka nui ʻāpana. ʻO ka hāʻawi ʻana i ka nui o nā ʻāpana, mai ka mono-modal a i ka bi-modal a me nā multi-modal, e ʻae i ka maʻalahi piha i ka hoʻolālā ʻana a hāʻawi i ka ʻoluʻolu o nā alumina reactive co-milled engineered.

ʻO nā micro-powders alumina reactive, i hana ʻia ma o ke kaʻina sintering kūikawā, ke kaʻina wili a me ka hoʻokaʻawale ʻana i ka nui o ka mana multistage, he kiʻekiʻe ka maʻemaʻe, maikaʻi ka puʻupuʻu nui a me ka hana sintering maikaʻi loa, i kūpono no ka noi i ka hana ʻana i nā mea refrac-tory kiʻekiʻe. , a me nā huahana seramika uila . Hiki ke hoʻomalu maikaʻi ʻia ka reactive alpha alumina micropowerd i ka puʻunaue ʻana i ka nui o nā ʻāpana i loko o ke ʻano o ka submicron, e alakaʻi ana me ka maikaʻi o ka palaoa packing density maikaʻi rheological waiwai a me ka hana paʻa a me ka hana sintering maikaʻi. kuleana ma refractory:

Nā Alumina Reactive no nā Refractory Hana Kiʻekiʻe

Hoʻolālā kūikawā ʻia nā alumina reactive lepo piha no ka hana ʻana i nā refractory hana kiʻekiʻe, kahi i wehewehe ʻia ai ka paʻipaʻi ʻāpana, rheology a me nā ʻano hoʻonohonoho kūlike e like me nā pono kino o ka huahana hope.

Hana Huahana
ʻO ka hāʻawi ʻia ʻana o ka nui o nā ʻāpana maikaʻi i hoʻomalu ʻia a hiki i ka pae sub-micron a me kā lākou hana hoʻoheheʻe sintering maikaʻi loa e hāʻawi i ka Reactive Aluminas i nā hana kūʻokoʻa i loko o nā hana refractory.

ʻO nā mea nui loa:
• E ho'ēmi i ka hui ʻana o ka wai monolithic refractory ma ke kōkua ʻana i ka hoʻonui ʻana i ka paʻi ʻāpana.
• Hoʻonui i ke kū'ē abrasion a me ka ikaika mechanical ma o ka hoʻokumuʻana i nā mea paʻa seramika ikaika.
• Hoʻonui i ka hana mīkini wela kiʻekiʻe ma o ka hoʻololi ʻana i nā mea superfine oflower refractoriness.
