Ka werohia e te ngongo alumina ātete-kakahu he kaha hou ki roto i te umanga kawe hau

I roto i te hanga ahumahi, he whānuitia te whakamahinga o te kawe hau i roto i te hiko, te matū me ētahi atu ahumahi, engari he raruraru tonu te pakaru o ngā paipa i roto i te ahumahi, e piki ake ana ngā utu, e pā ana hoki ki te hanga. Nā te putanga mai o ngā ngongo alumina ātete-kakahu kua ea tēnei raruraru, ā, kua waiho hei whiringa hou mō te ahumahi.

Ko ngā ngongo alumina ātete-kakahu he mea whakakikorua ki ngā uku alumina tino parakore, he tata ki te 90HRA te pakeke, ā, he maha ki te tekau ngā wā o te ātete-kakahu i ngā paipa rino noa. Ina panaia ngā rauemi e te hau tere-tere ki te pakitara o roto o te paipa, ka taea e ia te ātete ki te kakahu me te whakaroa i te roa o te mahi. Hei tauira, i roto i tētahi kamupene matū, ka tino kakahuria ngā paipa rino noa i roto i ētahi marama i te wā e kawe ana i ngā rauemi kei roto ngā matūriki totoka, ā, me whakakapi pinepine; i muri i te whakakapinga ki ngā ngongo alumina ātete-kakahu, ka iti te kakahu i muri i ngā tau maha o te mahi.

He pai hoki tōna ātete ki ngā pāmahana teitei. Ka taea e te arai uku te tu atu i ngā pāmahana teitei neke atu i te 1200℃, ā, he teitei ake te ātete ki te pāmahana i raro i ngā tukanga motuhake. Ka taea e ia te mahi pumau i roto i te kawe rauemi pāmahana teitei hei whakarite i te haumaru o te pūnaha kawe hau. Heoi anō, he kaha te pumau matū. Ina kawe rauemi waikura i roto i te umanga matū, ka taea e ia te ātete ki te waikura o ngā mea pērā i te waikawa, te kawakore, me te tote hei whakarite i te kawe o ngā hua matū.

Hei tāpiritanga, he māmā te ngongo alumina ātete-kakahu, ka taea te whakaiti i te kawenga ki te pūnaha paipa, he ngāwari ki te tāuta me te tiaki, ā, ka whakaiti i te whakapaunga pūngao. He maha ngā tikanga tāutanga, ā, ka taea te whiriwhiri i te tikanga hononga kia rite ki ngā hiahia kia urutau ki ngā taiao hangarau uaua.

I te whanaketanga o te hangarau ahumahi, kua piki ake ngā whakaritenga mō ngā pūnaha kawe hau. Nā tōna mahi tino pai, he whānui ngā tono mō te ngongo alumina ātete-kakahu. Ka taea e ia te whakaoti rapanga kakahu, te whakapai ake i te pai o te whakaputa, te whakaiti i ngā utu, te whakatairanga i te whanaketanga o te hangarau kawe hau, me te āwhina i ngā momo ahumahi kia whanake me te kounga teitei. Ka whai wāhi nui ia i roto i ngā āhuatanga maha atu i te heke mai.
