Ka mahi ngā oumu karāhe i roto i ngā taiao uaua me ngā pāmahana tino tiketike, te waikura kawakore me te ru wera pinepine. He mea nui ngā pereki ātete kounga teitei hei whakaū i te mahi o te oumu, hei whakamana i te kounga karāhe me te whakaroa i te roa o te ratonga taputapu. Mā te whiriwhiri tika i ngā pereki ātete oumu karāhe mā ngā rohe ka āwhina i ngā kaihanga karāhe ki te whakaiti i ngā utu tiaki me te whakatutuki i te whakaputanga tonu me te whai hua.
Ngā Pereki AZS Whakarewahia — He Ātete Matua mō ngā Rohe Rewa
Ko ngā pereki AZS whakarewa honohono te rauemi matua mō ngā rohe whakarewa karāhe. He mea hanga ki te alumina, te zirconia me te silica, he kaha te ātete ki te horo o te karāhe rewa, ā, he tino pumau te hanganga i te 1500°C ki te 1600°C. Ka taea te tu atu i te horoi wai karāhe pāmahana teitei me te waikura o te paipa kawakore mō te wā roa, he whānuitia te whakamahinga o ngā pereki AZS mō te whakarewa i ngā pakitara puna kaukau, ngā papa o te oumu me ngā wāhanga korokoro. Ka whakaitihia e rātou ngā mirumiru me ngā rārangi karāhe, kia pai ai te hanga hua karāhe kounga teitei.
Pereki Hiraka — Kōwhiringa Pai rawa atu mō ngā Karauna me ngā Hanganga o runga o te Oumu
Ko ngā pereki silica te mea tino pai mō ngā karauna oumu me ngā hanganga o runga. Neke atu i te 94% te nui o te silica, ā, he iti te horapa o te wera, he pumau te pāmahana teitei, ā, he ātete pai ki te waikura kawakore. Mā te pupuri i te kaha miihini pumau i runga ake i te 1600°C, ka ārai ēnei pereki i te hurihanga me te ngatata i te wā e whakamahia ana mō te wā roa. He mea whakamahi noa hoki i roto i ngā āwhata whakahou, i ngā paipa me ngā wāhi whare kuri hei whakapai ake i te roa o te oumu.
Ngā Pereki Hiraka Kua Whakakotahitia — Ngā Tūranga Motuhake Matua i roto i ngā Oumu Karāhe Hou
He tūranga motuhake ngā pereki silica hanumi i roto i ngā oumu karāhe hou. Mā te 99.5% o te silica parakore, ka tukuna e rātou he ātete tino pai ki ngā ru wera me te iti o te kawe wera. Ko te nuinga o te wā e whakamahia ana mō ngā kōhao hiko me ngā kōhao ine pāmahana, ko tō rātou whakamarumaru pai rawa atu ka ārai i te turuturu o te iahiko me te whakarite kia tika te aroturuki i te pāmahana, kia tutuki ai ngā paerewa mahi tino pakari mō ngā oumu karāhe hiko.
Pereki Alumina-Teitei me te Mullite — Ngā Āwhina Whakamātao Utu-Pai
He pai te utu mō ngā pereki konumohe-nui me ngā pereki mullite hei whakakapi i ngā pereki ātete ahi. He pumau te ātete ahi me te kaha miihini, ā, he pai mō ngā rohe pāmahana waenga me te pāmahana iti, tae atu ki ngā papa o mua, ngā pito mahi, ngā pakitara whakaora me ngā pereki tirotiro. He pai te ātete ki te ru wera me te waikura hau paru, me te whakataurite i te mahi pono me te utu whakataetae.
Mā te whakakotahitanga pūtaiao o ēnei pereki ātete-waikura ka tutuki pai ngā hiahia tiaki paparanga o ngā hanganga oumu karāhe. Mā ngā otinga ātete-waikura kua whakaritea kia ārai i te horo me te ngatata, ka whakaiti i te wā kore mahi me ngā utu tiaki, ā, ka roa ake te ora o te oumu.
I te mea he rerekē te taumaha o te oumu, te pāmahana me ngā tukanga whakaputa, ka ngāwari te whiriwhiri pereki kotahi-rahi-mō-te-katoa ki te whakaputa hapa me te ngaronga. Mena kei te hiahia koe ki ngā pereki ātete-wera mō te hanganga oumu hou, te whakahou, te whakakapi rānei, tēnā tukua mai he pātai. Kei a mātou ngā otinga ritenga takitahi, ngā whakatakotoranga tika, ngā utu wā-tūturu me te tautoko hangarau ngaio mō āu kaupapa oumu karāhe.
