E hoʻohana i nā seramika alumina kūpaʻa
ʻIke Huahana
ʻO ka alumini ceramic, i ʻike ʻia he alumini oxide a i ʻole Al2O3, he seramika oxide i hoʻohana nui ʻia i ka ʻoihana. ʻIke ʻia nā mea seramika alumina no ko lākou paʻakikī kiʻekiʻe a me ka conductivity thermal kiʻekiʻe. ʻO nā waiwai o nā seramika alumina e hoʻolilo iā ia i hoʻokahi o nā seramika i hoʻohana nui ʻia i ka hoʻolālā, ʻaʻahu a me nā kaiapuni corrosive.
Hōʻike ʻia ka alumini oxide e ka paʻakikī kiʻekiʻe, ka pale ʻana i ka corrosion, ke kūpaʻa wela, nā waiwai dielectric maikaʻi (no ka hoʻololi ʻana mai DC a hiki i nā alapine GHz), haʻahaʻa haʻahaʻa tangent a ʻoʻoleʻa.
Hoʻokaʻawale ʻia nā seramika alumina e like me ka ʻike Al2O3 i loko o ka mea. ʻO nā mea maʻamau: 75%, 95%, 99%, 99.5%, 99.7% alumina ceramics, etc. ʻO ka mea maʻamau, koho mākou i ka maʻemaʻe o nā alumina ceramics e pili ana i nā koi hana o nā huahana a mākou e hana ai.

1. Poepoe alumina
ʻO nā pōpō alumina he mau ʻāpana alumini oxide non-spherical i hoʻohana nui ʻia i ka ʻoihana petrochemical, mahiʻai a me nā ʻoihana uhi.
Hiki i nā pōpō alumina ke komo pololei i ka hopena, e hōʻemi nui i ka hopena i ka catalyst, a laila e hoʻolōʻihi i ke ola lawelawe o ka catalyst. Eia kekahi, hiki ke hoʻohana ʻia nā pōpō alumina e hana i nā uhi pale pale. Ma hope o ka pīpī ʻana i ka metala, ka plastic a me nā mea ʻē aʻe, hiki iā ia ke hoʻomaikaʻi i ka paʻakikī o ka ʻili, ka pale ʻana i ka corrosion, ke kūpaʻa ʻana a me ka retardancy ahi.
I loko o ka ʻoihana uila, he mea koʻikoʻi nā pōpō alumina spherical i ke kahua o ka ʻeke uila ma muli o kā lākou mau pono uila, wela a me nā mea hana.
Nui ka nui o nā ʻāpana: 0.3-0.4, 0.4-0.6, 0.6-0.8, 0.8-1.0, 1.0-1.2, 1.2-1.4, 1.4-1.6, 1.8-2.0, 2.0-2.2, 2.2-2.3, 2.2-2.3, 2.2-2.3 3.2, 3.2-3.5, 4.5-5.0, 5.0-5.5, 6.0-6.5, 6.5-7.0, 8, 10, 12, 15, 20.
Poepoe wili alumina
ʻO nā pōpō wili alumina he mau ʻāpana spherical i hana ʻia me ka alumina maʻemaʻe kiʻekiʻe a hoʻohana mau ʻia e like me nā abrasives a i ʻole nā mea wili. Ma muli o kona paʻakikī kiʻekiʻe a me ke kūpaʻa maikaʻi o ka lole, hoʻohana nui ʻia ia i nā ʻoihana me nā koi kiʻekiʻe no ka wili a me ke kūpaʻa ʻana.
