Pereki Arai Ukume Alumina me te Awaawa
Ngā Āhuatanga Matua
1) He pai te mau: Ko te paparanga uku chemshun i roto i te tāera uku ātete-mau kua whakakikoruatia ki te paipa tuke he uku pakū, he pakeke (HRA) ≥84, he 10 ngā wā te ātete mau atu i ngā hononga paipa rino maka konukōre teitei.
2) Ātete ki te waikura: he rauemi uku ātete ki te kakahu, he ātete ki te waikura, he waikawa, he kawakore, he tote me te tote halogen he āhuatanga pai rawa atu.
3) Te mahi pāmahana teitei: he kaha ake te kaha o ngā uku ātete ki te kakahu ki te pāmahana neke atu i te 1200 nekehanga Celsius.
4) Whakaitihia te utu o te kaupapa: e whakamahia ana mō te kawe i ngā matūriki, ngā wai me ngā rauemi waikura. te whakakapi i te maitai kore waikura utu nui, te paipa maitai whakarewa konukōre teitei, te ngongo koranu ātete-kakahu, ka taea te whakaiti tika i ngā utu kaupapa paipa.
He tino pai te ātete ki te mau me te pakaru
1) Ki te whakatauritea ki te raina paipa whakauru, he pai ake te utu hoko o te raina pereki paipa uku chemshun
2) He ngāwari ki te tāuta ki ngā taputapu
3) He ngāwari ki te whakatika ina pakaru tetahi wahi uku
4) Ka taea te whakakotahi noa i tetahi rahi ki te paipa whakauru
