I roto i te whakaputanga ahumahi, he mahi nui tā ngā paipa ki te kawe rauemi. I te wā e kawe ana i ngā rauemi he pakeke rawa, he waikura nui, he tere rere nui rānei, he wero nui te raruraru o te pakaru o ngā paipa mō ngā umanga. Nā te kore e tino ātete ki te pakaru, me whakakapi pinepine ngā paipa tuku iho, ā, ehara i te mea ka piki ake ngā utu engari ka arahi pea ki ngā whakararuraru whakaputanga. Hei whakaoti pai i tēnei raruraru, ka taea te whiriwhiri i ngā paipa kua whakakikoruatia ki te uku alumina. Ka taea e te ātete ki te pakaru pai te whakanui ake i te roa o te mahi a ngā paipa, ā, ka puta he painga nui ki te whakaputanga ahumahi.
Ngā uku arumina he rauemi kore-whakarewa kore-waro, he mea hanga nui ki te alumina (Al2O3), he tino pakeke, he ātete ki te kakahu me te waikura. He rauemi tino pai ēnei mō te whakaoti rapanga kakahu o ngā paipa.
1. He ātete kakahu pai rawa atu
Ko te pakeke o ngā uku alumina kei muri i te taimana, me te pakeke Mohs tae atu ki te 9, he nui ake i te maitai noa (me te pakeke Mohs tata ki te 5.5 ki te 6.5). Ko tōna ātete ki te kakahu he tekau, he rau rānei ngā wā i te maitai noa, ā, ka taea e ia te ātete pai ki te horo me te kakahu o ngā rauemi. I raro i ngā āhuatanga mahi ōrite, ko te roa o te ora o te paipa kua whakakikoruatia ki te uku alumina he 5 ki te 10 ngā wā i te paipa tuku iho, ka whakaiti nui i te auau o te whakakapinga paipa.
2. Ātete pai ki te waikura
He tino pai te pumau o ngā uku alumina, ā, ka taea te ātete ki te mimiti o ngā momo waikura pērā i te waikawa, te kawakore me te tote. I roto i ngā ahumahi pērā i te miihini matū me te rongoā, i te wā e kawe ana i ngā waikura, ka taea e ngā paipa kua whakakikoruatia ki te uku alumina te mahi pumau mō te wā roa, me te karo i ngā raruraru turuturu me te parahanga i puta mai i te waikura o ngā paipa.
3. Ātete pāmahana teitei
He teitei te ira rewa o ngā uku alumina (tata ki te 2050℃) ā, he tino pai te ātete ki te pāmahana teitei, e āhei ai te whakamahi mō te wā roa i roto i ngā taiao pāmahana teitei me te kore e rerekē te āhua, e pakaru rānei. I roto i ngā ahumahi pēnei i te hiko me te whakarewa, i te wā e kawe ana i ngā rauemi pāmahana teitei, ka taea e ngā paipa kua whakakikoruatia ki te uku alumina te tu atu ki ngā whakamātautau pāmahana teitei, kia mau tonu ai te mahi whakaputa.
4. Mata maeneene
He maeneene te mata o roto o te paipa uku alumina, ā, he iti te taratara, ka taea te whakaiti i te ātete rere o ngā rauemi i roto i te paipa, me te whakaiti i te whakapaunga pūngao. I taua wā, he iti ake te tūponotanga o te mata maeneene ki te piri ki ngā rauemi, ka whakaiti i te tūponotanga o te aukati i roto i te paipa.
Ko ngā paipa uku-ā-konumohe, me ō rātou ātete tino pai ki te kakahu, ki te waikura, ki te ātete ki te pāmahana teitei me te mata maeneene, kua waiho hei otinga whai hua mō te raruraru o te kakahu o ngā paipa. Ka taea e ia te whakanui ake i te roa o te mahi a ngā paipa, te whakaiti i ngā utu tiaki, te whakarei ake i te pai o te whakaputa, me te whakarite i te pumau me te ōhanga o te whakaputanga ahumahi. I te whanaketanga tonu o te hangarau ahumahi, kei te piki haere ngā whakaritenga mō te mahi paipa. Ka whakamahia whānuitia ngā paipa uku-ā-konumohe i roto i ngā ahumahi me ngā mara maha atu.
