ʻO White Corundum Grit White Fused Alumina me ke kūlana kiʻekiʻe
ALUMINA HOʻOPIHA KEʻOKEʻO
ʻO ka alumina hoʻoheheʻe keʻokeʻo (WFA) kahi mea maka no ka hana ʻana i nā mea refractories. Ua kapa ʻia hoʻi ʻo ia he corundum keʻokeʻo a i ʻole ka oxide alumini keʻokeʻo. Ke hoʻohālikelike ʻia me ka alumina hoʻoheheʻe ʻeleʻele, ʻoi aku ka like ma ke ʻano o ka haku mele kemika, ka hoʻonohonoho a me nā waiwai. ʻO ka hopena he huahana me ka paʻakikī kiʻekiʻe, ka friability kiʻekiʻe, ka maʻemaʻe kiʻekiʻe, ke kiko heheʻe kiʻekiʻe, a me ka nui o ke aniani nui. Hoʻohana nui ʻia ia i ka ʻoihana refractory, hiki ke hoʻohana ʻia i nā ʻano keramika wili huila, pepa one, nā mea pahū, ka hoʻomākaukau metala, nā uhi laminates, ka lapping, ka polishing, ka wili a me nā haneli o nā noi ʻē aʻe.

NĀ HIʻOHANA ALUMINA I HOʻOPIHA ʻIA KEʻOKEʻO
Hana ʻia ka alumina fused keʻokeʻo (WFA) mai ka pauka alumini oxide kiʻekiʻe/ pauka alumina nona ka wahi hoʻoheheʻe ma luna o 2200°CʻO wauhe paʻakikī kiʻekiʻe ko t, friability kiʻekiʻe, maʻemaʻe kiʻekiʻe. Me ke kūpaʻa wela maikaʻi o ka alumina White fused, hiki ke hoʻohana ʻia no nā mea refractory makau, nā mea hoʻoheheʻe refractory a me nā mea refractory ʻē aʻe.
Nā Pōmaikaʻi o ka Alumina i Hoʻohui ʻia i ke Keʻokeʻo
1. Hoʻomaʻemaʻe i nā ʻili metala me ka wehe ʻana i nā mea (hopena abrasive)
2. Ke wehe ʻana i ka ʻōpala a me ka unahi mai nā ʻili metala
3. Ke wehe nei i ke kala hoʻomehana
Nā noi ALUMINA FUSED KEʻOKEʻO
ʻO ka alumina keʻokeʻo i hoʻoheheʻe ʻia he ʻano maʻemaʻe loa ia o ka alumini oxide i kūpono no ka hoʻohana ʻana me ke kila kila a me ka alumini. He kihi, palupalu a paʻakikī kēia mea hoʻoheheʻe hao ʻole. Loaʻa iā ia kahi hopena abrasive ikaika ma ka ʻili e hoʻoheheʻe ʻia ana. No ka hui o ka alumina i hoʻoheheʻe ʻia ka alumina keʻokeʻo.
1. Ke one ʻana, ka hoʻowali ʻana a me ka wili ʻana i ka metala a me ke aniani.
2. Hoʻopiha ʻana i ka pena, ka uhi pale ʻaʻahu, ka seramika, a me ka glaze.
3. Hana ʻana i ka pōhaku ʻaila, ka pōhaku wili, ka huila wili, ka pepa one a me ka lole emery.
4. Hana ʻana o nā membrane kānana seramika, nā paipu seramika, nā papa seramika.
5. Hana ʻana o ka wai wili, ka waki paʻa a me ka waki wai.
6. No ka hoʻohana ʻana i ka papahele kūpaʻa.
7. ʻO ka wili ʻana a me ka poli ʻana o nā kristal piezoelectric, semiconductors, kila kila, alumini a me nā metala ʻē aʻe a me nā metala ʻole.
8. Nā kikoʻī a me ka haku mele ʻana
