ʻO ka pauka alumina/ʻa-Alumina Micropowder
wehewehe
ʻO ka pauka alumina he mea ʻole me ke ʻano kemika Al2O3.He pūhui paʻakikī kiʻekiʻe me ka helu heheʻe o 2054°C a me kahi helu hoʻolapalapa o 2980°C.He aniani ionic ia e hiki ke ionize ma ke kiʻekiʻe wela a hoʻohana pinepine ʻia i ka hana ʻana i nā mea refractory.
ʻO ka pauka alumina he alumina Al2O3 paʻa paʻa, hana maʻamau no ka pauka alumina α-al2o3, β-al2o3 alumina pauka, γ-al2o3 alumina pauka ma ke ʻano he hoʻohana ʻokoʻa.
α-Alumina micropowder
ʻO ka α alumina pauka he paʻa loa ke kino a me nā waiwai kemika, paʻakikī kiʻekiʻe, ke kūpaʻa ʻana, ka ikaika mechanical kiʻekiʻe, ka insulation, ke kūpaʻa wela kiʻekiʻe, ka haʻahaʻa haʻahaʻa o ke ahi, ka haʻahaʻa haʻahaʻa o ka hoʻonui ʻana i ka wela, ka conductivity thermal maikaʻi a me nā ʻano ʻē aʻe.
Hoʻohana pinepine ʻia ʻo α alumina ma ke ʻano he abrasive, toughening agent, refractory material, polishing material, etc.
Kaʻina Hana Hana
1. ʻO ka wili pōleʻa mea maka: kōkua i ka wehe ʻana i nā haumia, hoʻomaikaʻi i ka hoʻololi ʻana o ke kaʻina hana kī, a hoʻonui i ka wikiwiki o ka pane;
2. ʻO ka hoʻomoʻa ʻana o ka tunnel kiln: hiki ke hoʻokō ʻia ka hana hoʻomau a paʻa, a hiki ke hoʻomalu pono ʻia ka mahana wela;
3. Mea wili kinipopo Clinker: E wili i ka clinker i loko o ka nui o nā mea i makemake ʻia.
