Ngā Pereti Whakatakotoranga Arumina
Pereti arai konumohe (pereti arai uku ātete-mau konumohe)He hua tiaki ātete-mau, he mea hanga te nuinga ki te 92%/95% uku alumina hei rauemi mata. He whānuitia te whakamahinga i roto i ngā pūnaha whakahaere rauemi o te keri, te sima, te maitai, te hiko, te waro me ētahi atu ahumahi, ko te whāinga he whakaoti i te raruraru mau o ngā pakitara o roto o ngā taputapu i puta mai i te horoinga rauemi papatipu, te whakaroa i te roa o te ratonga taputapu me te whakaiti i ngā utu tiaki.
Whakarōpūtanga Hua Matua (Ngā Momo Matua)
1. Te Pereti Whakapiripiri:Ka whakamahia he kāpia whakamuri, he whakapiripiri rānei hei tāuta, he mea e tika ana mō ngā pakitara o roto o ngā taputapu papatahi me ngā āhuatanga mahi e memeha ana. He watea, he whai hua hoki te hanganga, ā, kāore he taputapu hanga uaua e hiahiatia ana.
2. Te Raina Whakarewa:He turanga whakarewa, he poraka whakarewa uku rānei tōna, he pai mō ngā mahi taumaha me te kaha o te pānga me te horoi rauemi taumaha. He pūmau, kāore e ngāwari te taka, ā, he roa ake te ora mahi.
3. Te Ārai Waiporoporo Āhua-Āwhata:He pereti arai pewa motuhake tēnei, he āhua motuhake kua whakaritea kia rite ki te mata pewa porowhita o te hydrocyclone. He rerekē i te pereti arai papatahi tuku iho, ka taea te whakauru pai i te pakitara o roto o te hydrocyclone, ā, ka taea hoki te whakaoti i te raruraru kakahu o te hydrocyclone.
Tuhipoka:Ko tēnei whakarōpūtanga e hangai ana ki te huinga o te tikanga tāutanga me te āhua tono, koinei te whakarōpūtanga matua i roto i te umanga. Ka taea hoki e mātou te whakarato i te whakarōpūtanga ritenga me te kōwhiringa hua e ai ki ngā whakaritenga pēnei i te ihirangi alumina, te matotoru me te tukanga rauemi.
Te Mahi Matua me ngā Āhuatanga:
1. Ātete Pakakahu Tino Pai me te Pakari Nui:Me te pakeketanga Mohs tae atu ki te 9, he nui ake i te maitai me ngā pereti koranu, ko tōna roanga mau he 10-20 ngā wā i te maitai waro noa, e kaha ana ki te ātete i te horoinga me te mau o ngā rauemi papatipu.
2. Mama me te Ātete Pānga:He iti te taumaha motuhake, ka taea te whakaiti i te kawenga o ngā taputapu me te kore e whakanui i te taumaha katoa o ngā taputapu. Mā te tukanga whakapakeketanga motuhake, ka tino pai ake tōna pakari pakaru, ā, ka taea te urutau ki ngā āhuatanga mahi uaua me te pānga o ngā rauemi.
3. Mata Maeneene me te Tino Whai Hua:He iti te tauwehenga waku o te hua, ka taea te whakaiti i te piri me te aukati o ngā rauemi, te whakapai ake i te whai huatanga o te kawe rauemi, me te whakaiti i te wā kore mahi o ngā taputapu i puta mai i te aukati.
4. Ngā Tāutanga me ngā Whakaritenga Kanorau:Ka tautokohia e ia ngā tikanga tāutanga maha pērā i te here piri, te whakarewa me te honohono hiku. I taua wā anō, ka taea te whakarite kia tapawhā, kia tapawhā rite, kia trapezoidal, kia āhua pā me ētahi atu āhua kia pai ai te whakauru i ngā paipa, ngā awaawa, ngā pekepeke, ngā awhiowhio me ētahi atu taputapu.
5. Te Mahi Pūmau me te Āheitanga ki te Taiao Kino:He pumau ōna āhuatanga matū, he ātete ki te waikura, he ātete ki te waikawa me te kawakore, kāore e paitini, ā, kāore hoki e poke. He pai hoki te pumau o te wera, e mau tonu ana te mahi pumau i raro i te āhua mahi mai i te -50℃ ki te 400℃, ā, he pai mō ngā taiao ahumahi me te keri maina uaua.
