Ko te Alumina Ma Whakakotahi Paerewa JIS mō ngā Kakahu Panipani Ko te Alumina Ma Whakakotahi WFA
Whakataki Alumina Whakakotahi Ma
Alumina hanumi mā (WFA)he rauemi whakakoi hangai i hangaia mā te whakakotahi i te parakore teiteikonumohei roto i te oumu hiko pewa i ngā pāmahana teitei. He hanganga tioata tōna e titoa ana i te corundum (Al2O3) ā, e mōhiotia ana mō ōnatino pakari, kaha, me te parakore teiteiKei te wātea te alumina mā kua whakaranua i roto i ngā āhua rerekē, tae atu kikirikiri, onepu, me te paura, ā, e whakamahia ana i roto i ngā momo tono:Te Huri me te Whakakanapa, te Whakarite Mata, ngā Mea Whakakākā, te Maka Tika, te Whakakākā Ārai, ngā Mea Ārai Tino Ārai, ngā Mea Uku me ngā Tāera, me ētahi atu.

Te Huri me te Whakakanapa: ngā wira whakakoi, ngā whitiki, me ngā kōpae mō te huri tika i ngā konganuku, ngā uku, me ngā mea hiato.
-
Te Whakarite i te Mata: te tango i te unahi, te waikura, te peita, me ētahi atu poke mata mai i ngā papa whakarewa
-
Ngā pereki mura: ngā pereki ahi, ngā pereki whakarewa mura, me ētahi atu hua mura āhua, āhua kore rānei
-
Te Maka Tika: he tino tika te āhua, he maeneene ngā mata, ā, he pai ake te kounga o te maka.
-
Te Whakapūtanga Whakakā: te tango i te waikura, te peita, te unahi me ētahi atu poke i ngā mata, me te kore e kino.
-
Ngā mea whakakoi tino kaha: ngā maitai tere-rahi, ngā maitai taputapu, me ngā uku
-
Ngā uku me ngā tāera
