Ko te papanga arai tika e tautuhi ana i te pono o te ahumahi—ina koa i ngā āhuatanga tino kino.Ngā pereki arai konumohe, i hangaia me te ihirangi 75–99.99% Al₂O₃, kua waiho hei whiringa matua puta noa i ngā rāngai matua, e whakaoti ana i ngā raruraru e kore e taea e ngā raina tuku iho te whakatika. Mai i ngā oumu sima wera-teitei ki ngā tipu matū waikura, ka tukuna e ā rātou tono maha he uara kore e taea te whakataurite i te mea e tino hira ana te mahi. Tūhurahia ō rātou pānga whakarerekētanga i roto i ngā ahumahi matua e rima.
Te Hanga Sima
Ka pāngia ngā oumu hurihuri me ngā whakamahana-mua e te pāmahana 1400°C+, te kiripaka whakakoi, me te whakaeke kawakore. Ko ngā pereki alumina (85–95% Al₂O₃) he pakeke Mohs 9 me te ātete wera teitei, e ātete ana ki te kakahu me te whakaiti i te ngaronga wera mā te 25–30%.
Te Keri me te Tukatuka Kohuke
Ka tere te pirau o ngā taputapu maitai i te konganuku, te kirikiri, me ngā paru. Ka whakaratohia e ngā arai konumohe (90%+ Al₂O₃) te ātete kakahu 10–20x atu i te maitai manganese, he mea pai mō ngā paipa, ngā mira pōro, me ngā awaawa. Ka whakaitihia e rātou te whakamahinga o ngā pāpāho mā te 30% me te ārai i te poke o ngā hua, he mea nui mō ngā kohuke parakore teitei. I whakaroahia e tētahi maina parahi o Amerika ki te Tonga te roa o te ora o ngā paipa paru mai i te 3 marama ki te 4 tau, ka whakakorea ngā utu whakakapinga ia marama me ngā kati kore i whakaritea.
Te Whakaputa Mana
Me whai arai ngā tipu wera, koiora, me ngā tipu para-ki-te-pūngao e ātete ana ki te wera nui, ki ngā hau paipa, me te horo o te pungarehu. Ka ātete ngā pereki konumohe ki ngā ru wera 500°C+ me te SOx/NOx waikura, ka pai ake i te maitai koranu.
Ahumahi Matū me te Hinu
Ka whakangaromia ngā arai tuku iho e ngā waikawa kaha, ngā kawakore, me ngā tote rewa. He koretake ngā matū o ngā pereki alumina tino parakore (99%+ Al₂O₃), ā, ka ātete ki te 98% waikawa whanariki me te 50% hauwai konutai.
Ārahi-ārahi me te Hangarau-Tirohia
Mā ngā pereki alumina tino parakore (99.99% Al₂O₃) ka taea te hanga i ngā haurua-ā-ira kore poke. Kāore he pūwero, kāore hoki e tauhohe, ka ārai i te tangohanga o ngā katote konganuku, ka pupuri i te ihirangi konganuku wafer ki raro i te 1ppm mō ngā maramara 7nm/5nm.
Mō ngā tono katoa, ka tukuna e ngā pereki arai alumina he parenga roa, he parenga whai hua hoki e ārahi ana i te hiranga o te mahi. Nā te ngāwari ki te urutau ki te wera, te pakū, te waikura, me te poke, he haumitanga mohio tēnei hei whakaiti i ngā utu me te whakanui ake i te hua.
Kua rite koe ki te kimi i tāu otinga e tika ana? Ka aromatawaihia e ā mātou tohunga ō hiahia—mai i ngā oumu sima pāmahana teitei ki ngā taputapu haurua-parakore tino parakore—ā, ka tukuna atu hoki he arai alumina kua whakaritea. Whakapā mai ki a mātou i tēnei rā mō tētahi whakatau utu, mō tētahi kōrero hangarau rānei. He kōrero noa iho te otinga arai tino pakari o tō umanga.
