ʻO nā huahana alumina me ka pauka alumina calcined e like me ka mea maka i loaʻa ka ikaika mechanical maikaʻi loa, kiʻekiʻe paʻakikī, kiʻekiʻe ka pale uila a me ka conductivity thermal maikaʻi.Hiki ke hoʻohana nui ʻia ka micropowder alumina calcined i nā lako uila, nā seramika i kūkulu ʻia, refractories, abrasives, polishing material, etc.

ʻO nā alumina Calcined he alpha-aluminas ka mea nui o nā agglomerates sintered o nā kristal alumina pākahi.ʻO ka nui o kēia mau kristal mua e pili ana i ke degere o ka calcination a me ka nui agglomerate ma nā ʻanuʻu wili ma hope.ʻO ka hapa nui o nā alumina calcined i hoʻolako ʻia i ka lepo (<63μm) a i ʻole ka lepo maikaʻi (<45μm).ʻAʻole hoʻopau piha ʻia nā agglomerates i ka wā o ka wili ʻana, he ʻokoʻa nui ia mai nā alumina reactive i hoʻoheheʻe piha ʻia e kahi kaʻina wili puʻupuʻu.Hoʻokaʻawale ʻia nā alumina calcined e ka maʻi soda, ka nui o ka ʻāpana a me ke degere o ka calcination.Hoʻohana ʻia nā alumina calcined lepo a me ka lepo maikaʻi ma ke ʻano he hoʻopiha matrix e hoʻomaikaʻi i ka hana huahana o nā ʻano hoʻohālikelike e hoʻokumu nui ʻia i nā mea kūlohelohe.

ʻO ka nui o nā alumina calcined e like me nā ʻāpana mineral lepo a no laila hiki ke hoʻololi maʻalahi i nā aggregates me ka maʻemaʻe haʻahaʻa.Ma ka hoʻonui ʻana i ka ʻike alumina holoʻokoʻa o nā hui ʻana a me ka hoʻomaikaʻi ʻana i kā lākou ʻāpana ʻāpana ma o ka hoʻohui ʻana i ka alumina maikaʻi, ua hoʻomaikaʻi ʻia ka refractoriness a me nā waiwai mechanical, e like me ka modulus wela o ka rupture a me ke kūpaʻa abrasion.ʻO ka koi wai o nā alumina calcined i wehewehe ʻia e ka nui o nā koena agglomerates a me ka ʻili o ka ʻili.No laila, ʻoi aku ka maikaʻi o nā alumina calcined me kahi haʻahaʻa haʻahaʻa e like me nā mea hoʻopiha i nā pōhaku lepo a me nā castables.ʻO nā alumina calcined kūikawā me kahi kiʻekiʻe o ka ʻili, hiki ke hoʻololi i ka pālolo e like me ka plasticizer i ka hui pū ʻana a me ka ramming.ʻO nā huahana refractory i hoʻololi ʻia e kēia mau huahana e mālama i kā lākou mau hiʻohiʻona hoʻonohonoho maikaʻi akā hōʻike i ka emi nui ʻana ma hope o ka maloʻo ʻana a me ke kī ʻana.

Alumina Calcined

Nā Alumina Calcined no nā Refractory

Ma muli o nā waiwai wela kiʻekiʻe o a-Alumina, ua hoʻohana ʻia nā Calcined Aluminas i nā noi refractory he nui, ma nā huahana monolithic a me ke ʻano.

Hana Huahana
Ma muli o ke kiʻekiʻe o ka milling a me ka nui aniani, lawelawe ʻo Calcined Aluminas i nā ʻano hana like ʻole i nā formulations refractory.

ʻO nā mea nui loa:
• Hoʻomaikaʻi i ka hana huahana ma o ka hoʻonui ʻana i ka ʻike alumina holoʻokoʻa o kēia mau mea hoʻohui me ka hoʻohana ʻana i nā mea maka maoli i mea e hoʻomaikaʻi ai i ka refractoriness a me nā waiwai mechanical.
• E hoʻomaikaʻi i ka hoʻopili ʻana i nā ʻāpana ma o ka hoʻonui ʻana i ka nui o nā ʻāpana maikaʻi e loaʻa ai ka ikaika ʻoi aku ka ikaika a me ke kūpaʻa abrasion.
• E hoʻokumu i ka matrix o ka refractoriness kiʻekiʻe a me ka maikaʻi o ka hoʻopū ʻana i ka wela ma ka hana ʻana me nā mea hoʻopili e like me ka Calcium Aluminate Cement a / a i ʻole nā pālolo.
