Ko te paura alumina te rauemi matua o te kirikiri alumina ma me ētahi atu mea whakakoi, he āhuatanga ātete ki te pāmahana teitei, te ātete ki te waikura me ngā āhuatanga pumau. Ko te Nano-alumina XZ-LY101 he wai mārama, kāore he tae, he wai korekore, e whakamahia whānuitia ana hei tāpiri i roto i ngā momo kapia kiriaku, kapia polyurethane, kapia epoxy, me ētahi atu. Ka taea hoki te waiho hei whakarewa wai, hinu rānei, ā, ka taea te pani ki ngā rauemi paninga karāhe, ngā kōhatu utu nui, ngā rauemi taputapu tika, me ētahi atu; ā, he rerekē ngā whakamahinga o ngā momo paura alumina rerekē. Ko te kaupapa e whai ake nei ko te whakauru i te whakamahinga o te paura alumina momo-α, γ, me te β.
1. paura α-alumina
I roto i te whatunga o te paura alumina momo-α, he piri ngā katote hāora ki te āhua hexagonal, he taurite te tohatoha o te Al3+ i roto i te pokapū taunga octahedral e karapotia ana e ngā katote hāora, ā, he tino nui te kaha whatunga, nō reira he tino teitei te ira rewa me te ira kohua. Kāore te waikura momo-α e rewa i roto i te wai me te waikawa. E kiia ana hoki ko te waikura konumohe i roto i te ahumahi. Koinei te rauemi mata taketake mō te hanga konumohe whakarewa; e whakamahia ana hoki hei hanga i ngā pereki ātete, ngā oko ātete, ngā paipa ātete, me ngā taputapu whakamātautau pāmahana teitei; ka taea hoki te whakamahi hei mea whakakoi, hei mea aukati mura. Ko te alfa alumina parakore teitei te rauemi mata mō te hanga korundum horihori, te rupi horihori me te hapaira horihori; e whakamahia ana hoki hei hanga i te papa o ngā ara iahiko whakauru nui o ēnei rā.
2. paura γ-alumina
Ko te alumina momo-γ he konumohe hauwaiwai i roto i te pūnaha whakamaroke taiao pāmahana-iti 140-150 ℃, e kiia ana hoki ko te ahumahi ko te alumina hohe, ko te kāpia konumohe. Ko te hanganga o te katote hāora e tata ana ki te taha poutū o te pokapū e piri tata ana, ko te Al3 + e tohatohahia ana i roto i te katote hāora e karapotia ana e ngā āputa octahedral me te tetrahedral. Ko te alumina momo-γ kāore e rewa i roto i te wai, ka taea te rewa i roto i te waikawa kaha, i te otinga kawakore kaha rānei, ka werahia ki te 1200 ℃ ka hurihia katoa ki te alumina momo-α. Ko te alumina momo-γ he rauemi porotaka, ko te horahanga o roto o ia karamu tae atu ki te rau mita tapawha, he kaha te kaha o te adsorption. Ko te hua ahumahi he matūriki porotaka kore tae, he paku māwhero rānei me te ātete pēhanga pai. I roto i te ahumahi hinu me te ahumahi petrochemical e whakamahia whānuitia ana hei adsorbent, catalyst me te carrier carrier; i roto i te ahumahi he hinu whakawhiti, he kaihoko deacidification hinu turbine, e whakamahia ana hoki mo te tātari paparanga tae; I roto i te taiwhanga, he kaha te whakamaroke, ā, kāore tōna kaha whakamaroke i iti iho i te phosphorus pentoxide, ā, i muri i te whakamahinga i roto i te 175 ℃ wera mō te 6-8h ka taea hoki te whakaora me te whakamahi anō.
3.β-alumina paura
Ka taea hoki te kī ko te paura alumina momo-β he paura alumina hohe. He kaha te kaha ā-mīhini o te paura alumina hohe, he kaha te waikura, kāore e pupuhi, e ngatata rānei i muri i te mimiti i te wai, kāore he paitini, kāore he kakara, kāore e wairewa i roto i te wai me te etanoru, he kaha te mimiti mō te fluorine, e whakamahia ana mō te tango i te fluoride i roto i te wai inu i ngā wāhi he nui te fluorine.
Ka taea e te alumina whakahohe te mimiti i te wai mai i ngā hau, te kohu wai me ētahi wai. I muri i te mimititanga o te wai, ka taea te whakaora mā te tango i te wai mā te whakamahana i te pāmahana tata ki te 175-315°C. Ka taea te mimiti me te whakaora i ngā wā maha. Haunga te whakamahinga hei whakamaroke, ka taea hoki e ia te mimiti i te kohu mai i te hāora poke, te hauwai, te hauhā waro, te hau māori me ētahi atu o ngā hinu whakahinuhinu. Ka whakamahia hoki hei kaikawe me te kaikawe, hei kaikawe hoki mō te tātari paparanga tae.
