Ka tiakina e te uku alumina te pūwero rokiroki mai i te pānga o te waikura

I te wāhanga whakahaere rauemi o te hanga ahumahi, ko ngā silo me ngā hoppers, hei taputapu matua mō te rokiroki me te kawe rauemi, he mana whakahaere tō rātou e pā tika ana ki te whai huatanga me te pumau o te tukanga whakaputa katoa. Heoi, ko te rere pinepine me te waku o ngā rauemi i roto i ngā silo me ngā hoppers ka tino ngawari te pakaru o ngā pakitara o roto o ngā taputapu. Ehara i te mea ka whakapoto noa i te roa o te mahi a ngā taputapu, ka piki ake hoki ngā utu tiaki, engari ka arahi pea ki ngā aukati whakaputa nā te ngoikore o ngā taputapu, ka hua ake he mate ōhanga nui mō ngā umanga.

He rauemi uku mahi matatau te uku alumina, ā, he tino pakari, he tino ātete hoki ki te kakahu. Mā te whakatauranga pakeke o te HRA85, neke atu rānei, koia te tuarua ki ngā rauemi tino-pakari pērā i te taimana me te nitride boron cubic, ā, he nui ake tōna pakeke i ngā rauemi konganuku noa. Mā tēnei pakeke teitei ka taea e ngā arai uku alumina te pupuri i te āhua o te mata ina pāngia e te horoinga me te karawarawa nui mai i ngā rauemi rerekē, ā, ka tino ātete ki te kakahu.

I roto i ngā mahi whaihua, ahakoa kei te anga atu ki ngā konganuku me ngā waro kei roto ngā matūriki koi, ngā rauemi mata matū waikura rānei, he tino ātete ngā arai uku alumina ki te kakahu. Ki te whakatauritea ki ngā arai whakarewa tuku iho, ka taea te whakaroa i te roa o te ora o ngā arai uku alumina mā te maha o ngā wā ki te tekau ngā wā. Hei tauira, i roto i ngā whare tukatuka konganuku o tētahi kamupene keri, me whakakapi ngā arai whakarewa i whakamahia tuatahitia i ia 3 ki te 6 marama i te toharite. Whai muri i te huri ki ngā arai uku alumina, ka whakaroahia te roa o te ora ki te 2 ki te 3 tau, ka tino whakaiti i te auau me ngā utu tiaki taputapu.

Ngā arai uku aluminaka taea te hanga ritenga kia rite ki ngā rahi me te āhua tuturu o ngā silo me ngā hoppers, kia māmā ai, kia tere ai hoki te tāutanga. Mō te tiaki, me tirotiro noa i ngā wā katoa mō te pakaru, me whakakapi wāhanga ina hiahiatia. Ko te hua o tēnei he iti ngā utu tiaki, ā, he māmā noa iho ngā mahi.
