I tēnei wā, ko te whakamahinga matua o te pseudo-boehmite he rauemi mata mō te whakarite i te alumina me te piri mō te whakakorikori uaua ki te hanga, ki te kawe whakakorikori rānei. He nui te horahanga mata motuhake o te alumina i hangaia mā te tunu i te pseudo-boehmite, ā, e whakamahia whānuitia ana hei whakakorikori me te kawe whakakorikori i roto i te umanga hinu.
1. whakamahia mō ngā rauemi mata o te nanometer alumina
Ko tētahi o ngā WHAKAMAHINGA nui o te pseudo-boehmite ko te rauemi mata o te konumohe waikura. I runga i ngā āhuatanga o te horahanga mata motuhake nui, te kaha mahi me te kaha mimiti o ngā rauemi mata, kua whakamahia hei hanga i ngā uku hanganga pāmahana-tiketike pērā i ngā uku konumohe nitride. Hei tāpiri, he tino pai te nano-Al2O3 mō te whakakanapa matū miihini (CMP), mā te nano-Al2O3 hei matūriki huri i hangaia e te paru CMP ka taea te whakamahi i te paparanga waenga o te tukanga whakaputa IC hei rauemi waea haurua-ira me ngā rauemi kiriata pērā i te tungsten, te konumohe, te whakaparaha parahi, me te karāhe whatu matatau, te karaihe quartz me ngā momo whakakanapa kohatu.
Ka taea te whakamahi i te Pikitia -Al2O3 mō te whakakanapa matū me te miihini i ngā matūriki whakakoi.
2. Mō te whakakorikori hauwai
Hei whakatutuki i ngā whakaritenga o te whakamahinga o ngā rauemi hinu me te hinu ma, kua whānuitia te whakamahi i te hangarau hauwai, ko te whakakorikori hauwai te uho o te hangarau hauwai, e whakamahia ana mō te whakakorikori hauwai, ko te kawe gamma alumina he mea hanga mai i te diaspore angiangi mā te tunu i te maroke, he horahanga mata motuhake, he tomokanga me te tohatoha pore ka taea te whakarite, he rerekē te pokapū waikawa o te mata. He kaha miihini pai ake me te pumau wera, me ngā āhuatanga iti te utu.
He mea nui ngā whakakorikori whakairoiro mō te whakaputa hua hinu
I roto i te umanga whakamahine hinu me te matū hou, neke atu i te 90% o te tukanga tauhohenga matū e whakatinanahia ana e te tukanga whakatere, nō reira kua noho te whakatere hei matua ki te whakatinana i ngā tukanga whakatere hou me te whanaketanga hua hou. I roto i te umanga whakamahine hinu, he mea whakamahi noa ngā whakatere totoka, he mea tito mai i te kaikawe me te wāhanga hohe. Ko te kaikawe he wāhanga motuhake o te whakatere totoka, ka taea te whakanui ake i te horahanga mata motuhake, te whakapai ake i te ātete wera me te kaha miihini. He maha ngā momo kaikawe e whakamahia ana e te whakatere, pērā i: te alumina, te tātari ngota, te silica gel, te silica gel, te waro whakahohe me te oneone diatomaceous. Heoi, ko te nui o te kaikawe alumina e neke atu ana i te haurua o te nui katoa o te kaikawe whakatere. Ko te whakatere pakaru whakatere (FCC) te kaupapa matua o te tukanga pakaru whakatere. I te mea he taumaha, he iti iho hoki te hinu mata o te ao, i roto i te whakaranu rauemi mata pakaru whakatere, kua noho te hinu toenga hei huarahi tukatuka e whakamahia whānuitia ana, nō reira me horapa te whakatere pakaru whakatere hinu (FCC) ki te kōhao nui, ā, me tika te kiato waikawa o te kōhao nui i waenganui, kia pai ake ai te kaha pakaru whakatere o ngā matū macromolecular i roto i te mata. ngā rauemi. Ko te alumina hohe e whakamahia whānuitia ana hei whakapai ake i te anga whakakorikori. Ko te nui o te pūwero e āwhina ana ki te horapa o ngā matū macromolecular ki roto i ngā matūriki whakakorikori, ko te horahanga mata motuhake teitei e āwhina ana ki te horapa o te konganuku hohe, kia pai ake ai te mahi tauhohenga o te whakakorikori.
3. Whakamahia hei piripiri
Ko te kawe diaspore angiangi tataitia e whakamahia ana hei kaihoko here ehara i te mea he pai anake mō te hanga, engari ka pā hoki ki te mahi a te whakakorikori. I kitea e ngā kairangahau i roto i te tukanga honohono o te whakakorikori Ce – Mn/TiO2 hei kaihoko here, ehara i te mea he whakapai ake i te kaha ā-pūkaha o ngā whakakorikori, engari he whakapai ake hoki i te whakakorikori whiriwhiri surfactant denitration.
4. te whakatika i te paninga -Al2O3
Ko te mahi o te paninga i te paparanga o te mata kawe he whakanui ake i te horahanga mata motuhake o te tikanga e whakamahia whānuitia ana, ko te gamma alumina tētahi o ngā rauemi paninga e whakamahia whānuitia ana, he nui te horahanga mata motuhake, e āwhina ana i te wāhanga hohe i roto i te tohatoha whai hua i roto i te tukanga whakakī, ko te whakarite i te paninga gamma alumina e whakamahia whānuitia ana mō te AlOOH precursor sol, ko te alumina sol kia angiangi te diaspore hei rauemi mata, te whakarite, mā te whakamahi i te tikanga o te tukanga peptization waikawa he ngāwari ki te whakahaere, ka taea te whakamahi mō te hanga ahumahi.
