Pēpi-pōhīte

Ko te pseudo-boehmite te matū pai rawa atu i te wā e hangaia ana te gamma alumina, nā te mea ko te tango noa i te wai mā te whakapūkara i te 447 C pea te mea e hiahiatia ana. Ko te whakahaere i ngā taurangi mahi i te wā e hangaia ana te pseudo-boehmite: ko te supersaturation o ngā otinga he mea nui rawa atu, me te pH, te pāmahana, ngā poke me te āhua o ngā tauhohenga [3,4]. Kia tika te parakore o tēnei rauemi, ā, ko ēnei taurangi ka whakatau i te āhua, te kakano me ōna hanganga o te matū. Nō reira, he mea tika kia whai i ngā āhuatanga e puta ana i te wā e hangaia ana, kia taea ai te matapae i te hua me te kounga o te hua whakamutunga. I roto i tēnei mahi, i whakawhanakehia te hanganga o te pseudo-boehmite mā te tikanga o te whakamakuku, mā te whakamahi i te otinga konumohe sulfate supersaturated kounga ahumahi me te haukinia hauwai kukū (28%) hei matū tauhohenga; i whakapaitia tēnei tikanga e mōhiotia ana mā te whakaiti i te pāmahana tauhohenga i raro i te pūwāhi kohua o te haukini. I tutuki te whakahaere pāmahana o te reo tauhohenga mā te kohikohi raraunga me te whakahaere aunoa i te reo whakamahana. E whakaatuhia ana ko te whakahaere i te tauhohenga i ngā āhuatanga isothermal ka whakarite i te kounga whakamutunga o te pseudo-boehmite i hangaia.
