Paura Waikura Konumohe Ma WFA
He mea hanga te paura alumina mā kua hanumihia ki te paura alumina iti-konutai tino parakore, mā te rewa i te pāmahana tiketike, te whakamatao kia whakatiotia, kātahi ka kuru. Kei raro i te mana whakahaere pakari te paura waikura konumohe mā kua hanumihia kia mau tonu te tohatoha rahi o te kōpura me te āhua ōrite.
He whāiti te horapa o te rahi o te kōpura o te paura alumina mā kua hanumihia. I muri i te tukatuka āhua, he kōpura tino parakore te paura korundum mā, he koi ngā taha me ngā kokonga, he pai te huri, he kanapa te oro. He nui ake te pai o te huri i ngā mea whakakoi ngohengohe pērā i te silica.
Nā te āhua pai, he teitei te āhua o te mata o te mea kua orohia. He whānuitia te whakamahinga mō te huri me te whakakoi i ngā mea haurua-ira, ngā tioata, ngā papa hiko, te konumohe, te maitai, te kowiri tira, te kōhatu, te karāhe, me ētahi atu. Ina koa i roto i te umanga huri me te whakakoi i te kowiri tira, te konumohe, te parahi me ētahi atu rauemi whakarewa me te umanga karāhe, e whakaatu ana i te mahi tino pai.
Paura Alumina Ma kua Whakakotahitia
Mā, he karaihe α neke atu i te 99%, he parakore teitei, he pakeke teitei, he pakari teitei, he kaha tapahi kaha, he pumau matū kaha, ā, he kaha te whakamarumaru.
