Ka hoʻokaʻawale ʻana o ka bauxite

ʻO ka Bauxite, ka mea i kapa ʻia ʻo ka bauxite a i ʻole ka bauxite, ka mea nui o ka alumini oxide a loaʻa nā mea haumia. He ʻano paʻakikī loa ka Bauxite a he huaʻōlelo maʻamau ia no nā ʻano ores alumina hydrous me nā kumu honua ʻokoʻa loa.

Wahi a ka hoʻohana ʻana i ka bauxite, ua māhele ʻia i loko o ka metallurgical grade, chemical grade, refractory grade, grinding grade, cement grade, etc. Hoʻohana ʻia ʻo Bauxite clinker me nā ratio kūpono o AL2O3 / Fe2O3 a me AL2O3 / SiO2 e hoʻoheheʻe i ka alumina.

1. Kiʻekiʻe refractory mahana, ikaika thermal paʻa, a me ka pohā. ʻO ke one alumini mullite kahi huahana aluminika-silikona. Ma hope o ka calcination, ʻoi aku ka nui o kona refractoriness a me ke kūpaʻa haʻalulu wela ma mua o ke one quartz me kahi ʻano hana aniani i haku ʻia me ka silika aniani hoʻokahi. ʻAʻole hiki ke hoʻomaʻemaʻe ʻia e ka metala wai e hoʻoheheʻe haʻahaʻa, hiki ke lanakila i ke one Quartz he nui ka nui o ka hoʻonui ʻana i ka wela a me ka hopena maikaʻi ʻole i ka wā condensation, e hopena i nā hemahema e like me ka haʻahaʻa o ka hoʻolei ʻana a me ke one pipili.

2. ʻOkoʻa ʻāpana gradation, maikaʻi breathability. Hoʻopili ʻia ke one Foundry e Raymond mill a hui pū ʻia e like me ka hoʻokaʻawale ʻana o nā ʻāpana kikoʻī i ka wā o ka hana ʻana e hoʻomaikaʻi i ka permeability o ka pena. Eia kekahi, ʻoi aku ka maikaʻi o ka mālama ʻia ʻana o nā huahana e nā wili pōpō, nā ʻāpana one hoʻoheheʻe ʻia e nā wili ʻo Raymond, a ʻoi aku ka ʻepekema o ka nui o ka bauxite clinker.

3. He kiʻekiʻe ka fusion, ka ikaika kiʻekiʻe a me ka demoulding maʻalahi nā uhi. Hoʻohana ʻia nā mea hoʻoheheʻe refractory ʻē aʻe i nā huahana alumini-silicon clinker, pauka maikaʻi bauxite clinker i nalowale, e like me nā ʻāpana ʻāpana like ʻole mai loko waho. ʻO ka huiʻana mai ka maikaʻi a hiki i ke koʻikoʻi ka hopena i kahi kiʻekiʻe o ka hoʻohuiʻana ma waena o nā pale; ʻoiai e hoʻonui ana i ka ikaika o ka uhi a me ka pale ʻana i ka erosion e pale ai i nā pilikia e like me ka hāʻule ʻana, ʻoi aku ka maʻalahi o ka demould. A ʻo ka bauxite mullite kahi mea kūʻokoʻa, a hiki ke hoʻohana ʻia ka bauxite clinker e like me nā mea hoʻopaʻa ʻakika a me ka alkali.
