ʻO ka ʻokoʻa ma waena o ka corundum brown a me keʻokeʻo

1.ʻO nā meaʻokoʻa'ē aʻe:ʻo ka mea maka o ka corundum brown he bauxite, me ka anthracite a me ka hao. ʻO ka mea maka o ka corundum keʻokeʻo he alumini oxide pauka.
2.ʻOkoʻa waiwai: brown corundum i nā hiʻohiʻona o ke kiʻekiʻe maʻemaʻe, maikaʻi crystallization, ikaika fluidity, haʻahaʻa coefficient o linear hoʻonui, corrosion kū'ē. Loaʻa i ka corundum keʻokeʻo nā hiʻohiʻona o ka maʻemaʻe kiʻekiʻe, ka hoʻomaʻamaʻa ponoʻī maikaʻi, ka ʻakika a me ka pale ʻana i ka corrosion alkali, ke kūpaʻa wela kiʻekiʻe a me ka hana thermal paʻa. I ka hoʻohālikelike ʻana, ʻoi aku ka paʻakikī o ka corundum keʻokeʻo ma mua o ka corundum brown.
3.ʻO nā meaʻokoʻa likeʻole:ʻoiaiʻo ka'ōleʻele a me ke keʻokeʻo keʻokeʻo i loko o ka alumina, keʻokeʻo keʻokeʻo i ka alumina,
4. Nā kala like ʻole: No ka mea, ʻoi aku ka kiʻekiʻe o ka alumina o ka corundum keʻokeʻo ma mua o ka corundum brown, ʻo ke kala o ka corundum keʻokeʻo keʻokeʻo, a ʻo ka corundum brown he ʻeleʻele ʻeleʻele.
5. ʻO ka hana like ʻole: hana ʻia ka corundum keʻokeʻo me ka pauka alumina (ʻo ia ka mea maka e like me ka alumini electrolytic), aʻo ka corundum brown i hana ʻia me ka calcined bauxite.
6.White corundum he ikaika ʻoki ikaika, hoʻohana ʻia no ka wehe ʻana i ka metala a i ʻole nā ​​​​mea hao ʻole, batch front burr, etc. Aia ka hana o ka polishing parts surface, brown corundum i hoʻohana ʻia e wehe i ke kila kila, ke kila kalapona, ka alumini alumini a me nā lako ʻē aʻe. ʻāpana ʻili burr
7. ʻO ka hoʻohanaʻana i nā mea likeʻole: hoʻohanaʻia ka corundum keʻokeʻo e kekahi mau mea hoʻohana kiʻekiʻe, no ka mea,ʻoi aku ka maikaʻi o kaʻokiʻana i ka ikaika, maikaʻi loa ka hopena polishing, hoʻohana nuiʻia no ke kila kalapona, ke kila kila, ka hao malleable, ke keleawe paʻakikī a pēlā aku. a ua hoʻohana nui ʻia ka corundum brown ma ka mākeke, akā ʻoi aku ka nui o ke ʻano o ka mākeke, hoʻohana nui ʻia no ke kila ahi, ke kila kiʻekiʻe, ke kila kalapona kiʻekiʻe a pēlā aku.
ʻO ka corundum keʻokeʻo he ikaika ʻoki ikaika, hoʻohana ʻia no ka wehe ʻana i ka metala a i ʻole nā ​​​​mea metala burr, batch front burr, a me nā mea ʻē aʻe. burr. ʻAʻole wili ʻia ka corundum ʻulaʻula e like me ka maikaʻi a me ka ʻulaʻula e like me ka corundum keʻokeʻo.
