Ka taea e te kōrunuma parauri te whakakapi i te kōrunuma mā i roto i ngā mea whakakoi me ngā taputapu huri? ——Ngā Pātai me ngā Whakautu Mātauranga
P1: He aha te kōrundum parauri me te kōrundum mā?
Korunuma paraurihe mea whakakoi i hangaia mai i te bauxite hei rauemi mata matua, ā, ka whakarewaina i te pāmahana teitei. Ko tōna wāhanga matua kowaikura konumohe(Al₂O₃), me te ihirangi tata ki te 94%, neke atu rānei, ā, he iti noa te waikura rino me te waikura silicon kei roto. He mea whakakoi parakore te kōrunuma mā, ā, ko tōna wāhanga matua he waikura konumohe, engari he parakore ake (tata ki te 99%), ā, tata kore he poke.
P2: He aha te rerekētanga o te pakeke me te pakari i waenganui i te kōrunuma parauri me te kōrunuma mā?
Pakeke: He nui ake te pakeke o te kōrunuma mā i tekōrunuma parauri, nō reira he pai mō te tukatuka i ngā rauemi tino pakeke. Pakari: He kaha ake te pakari o te kōrunuma parauri i te kōrunuma mā, ā, he pai mō ngā wāhanga he nui te ātete ki te pānga pērā i te huri taratara, te huri taumaha rānei.
Q3: He aha ngā wāhi matua e whakamahia ai te kōrundum parauri?
Nā tōna pakari nui me tōna pakeketanga taurite, ka whakamahia te kōrunuma parauri ki: ngā mea tino kahahuringā āhuatanga pēnei i te huri taratara me te huri taumaha. Te tukatuka i ngā rauemi he pakeke taurite, pēnei i te maitai, te whakarewa, me te rakau. Te whakakanapa me te pupuhi onepu, inā koa te whakataratara i te mata.
P4: He aha ngā whakamahinga noa o te kōrundum mā?
Nā te mea he tino pakeke, he tino parakore hoki, ka whakamahia te kōrunuma mā mō: te huri me te whakakanapa tika, pērā i te tukatuka i ngā konganuku tino pakeke me te maitai kore waikura. Te tukatuka i ngā wāhanga hiko me ngā uku me ngā mata e hiahiatia ana he nui. Ngā mara tukatuka tino tika pērā i ngā taputapu hauora me ngā taputapu whatu.
P5: I roto i ēhea āhuatanga ka taea e te kōrundum parauri te whakakapi i te kōrundum mā?
Ngā āhuatanga ka taea te whakakapi i te korundum paraurikōrunuma mātae atu ki: he iti te pakeke o te rauemi tukatuka, ā, kāore e hiahiatia kia tino teitei te pakeke o te mea whakakoi. Kāore i te teitei ngā whakaritenga tika o te tukatuka, pērā i te huri mata, te tango rānei i ngā pakaru. Mēnā he iti ngā utu ōhanga, ka taea e te whakamahinga o te kōrunuma parauri te whakaiti i ngā whakapaunga.
P6: I roto i ēhea āhuatanga kāore e taea te whakakapi i te kōrundum mā ki te kōrundum parauri?
Ko ngā āhuatanga e kore e taea te whakakapi i te kōrunuma mā ki te kōrunuma parauri ko: te tukatuka tika o ngā rauemi pakeke-teitei, pērā i te maitai waro-teitei me te maitai kore waikura. Ngā āhuatanga tukatuka me ngā whakaritenga mata tino teitei, pērā i te oro whakaata whatu. Ngā tono e pāngia ana e ngā poke whakakoi, pērā i ngā taputapu hauora, te tukatuka haurua-ira rānei.
Q7: He aha te rerekētanga o te utu i waenga i te kōrundum parauri me te kōrundum mā?
Ko ngā rauemi matua o te kōrunuma parauri me te kōrunuma mā he kōhatu konumohe; engari nā te rerekētanga o ngā tikanga tukatuka, he iti ake te utu whakaputa o te kōrunuma parauri, nō reira he iti ake te utu i te kōrunuma mā. Mō ngā kaupapa he iti te tahua, he otinga ōhanga ake te whiriwhiri i te kōrunuma parauri.
Q8: Hei whakarāpopototanga, me pēhea te whiriwhiri i te mea whakakoi tika?
Me whakatau te kōwhiringa o te kōrunuma parauri, te kōrunuma mā rānei, kia rite ki ngā hiahia motuhake:
Mena he huri taratara, he whakahaere utu rānei ō hiahia tukatuka, he pai ake te whakamahi i te kōrunuma parauri. Mena he nui ngā whakaritenga tika mō te tukatuka, ā, he konganuku pakeke ake, he wāhanga tika rānei te mea tukatuka, me whiriwhiri te kōrunuma mā. Mā te tātari tika i ngā āhuatanga o ngā mea e rua, ka kitea e koe te taurite pai i waenga i te mahi me te utu. Mena he pātai tonu āu, ka taea e koe te kōrero atu ki ngā tohunga i runga anō i te horopaki tono tūturu.
