He tirohanga whānui mō te alumina kua whakahohehia
Ko te alumina whakahohe, e mōhiotia ana ko te bauxite whakahohe, ka kiia ko te alumina whakahohe i te reo Ingarihi. Ko te alumina e whakamahia ana i roto i ngā whakakorikori ka kiia ko te "alumina whakahohe". He rauemi totoka pūwero, he tino marara, he whānui te horahanga o te mata. Kei roto i tōna mata moroiti ngā āhuatanga e hiahiatia ana mō te whakakorikori, pērā i te mahi adsorption, te mahi mata, te pumau wera pai rawa atu, me ētahi atu, nō reira e whakamahia whānuitia ana hei whakakorikori me te kawe whakakorikori mō ngā tauhohenga matū.
He matūriki porowhita ma te mea e mimiti ana i te hinu pēhanga alumina whakahohe porowhita. He rite te rahi o te matūriki o te alumina whakahohe, he maeneene te mata, he kaha te miihini, he kaha te waikura, kāore e pupuhi, e ngatata rānei i muri i te mimiti wai, ā, kāore e rerekē. Kāore he paitini, kāore he kakara, ā, kāore e rewa i roto i te wai me te etanoru.
Arumina
Kāore e wairewa i roto i te wai, ā, ka taea te wairewa mārire ki roto i te waikawa whanariki kukū. Ka taea te whakamahi hei whakapai ake i te konganuku konumohe, ā, he rauemi mata hoki mō te hanga oko whakarewa, te porcelain, ngā rauemi ātete ahi me ngā kohatu hangai.
Ko te alumina e whakamahia ana hei ngongo, hei whakakorikori, hei kawe whakakorikori hoki, e kiia ana ko te "alumina whakahohe". He āhuatanga tōna o te porosity, te marara nui, me te horahanga mata motuhake nui. He whānuitia te whakamahinga i roto i ngā mara maimoatanga wai, matū hinu, matū pai, koiora me te rongoā.
Ngā āhuatanga o te alumina
1. He nui te horahanga mata motuhake: he nui te horahanga mata motuhake o te alumina whakahohe. Mā te whakahaere tika i te pūnaha sintering o te alumina, ka taea te whakarite i te alumina whakahohe me te horahanga mata motuhake tae atu ki te 360m2 / G. Ko te alumina whakahohe i whakaritea mā te whakamahi i te konumohe hauwai colloidal i wetewetehia e te NaAlO2 hei rauemi mata he iti rawa te rahi o te pore me te horahanga mata motuhake tae atu ki te 600m2 / g.
2. Hanganga mō te rahi o ngā pūwero ka taea te whakarerekē: I te nuinga o te wā, ka taea te whakarite i ngā hua he rahi waenga te pūwero mā te tunu ki te hauwai konumohe parakore. Ka taea te whakarite i ngā hua he rahi pūwero iti mā te whakarite i te alumina whakahohe me te kāpia konumohe, me ētahi atu. Ko te alumina whakahohe he rahi pūwero nui ka taea te whakarite mā te tāpiri i ētahi matū waro, pērā i te ethylene glycol me te muka, i muri i te tahunga.
3. He waikawa te mata, ā, he pai te pumau o te wera.
Te mahi a te alumina kua whakahohehia
Kei roto i te kāwai o te alumina matū te alumina whakahohe, e whakamahia ana hei mimiti, hei horoi wai, hei whakakorikori me te kawe whakakorikori. Ka taea e te alumina whakahohe te mimiti i te wai i roto i te hau, te mamaoa wai me ētahi wai. Kia mākū te mimiti, ka taea te whakamahana i te 175-315 pea. He pai. Ka taea te mimiti me te whakahohe anō i ngā wā maha.
Haunga tōna whakamahinga hei whakamaroke, ka taea hoki e ia te mimiti i te kohu hinu whakahinuhinu mai i te hāora poke, te hauwai, te hauhā waro, te hau māori, me ētahi atu. Ā, ka taea te whakamahi hei whakakorikori me te tautoko whakakorikori, hei tautoko hoki mō te tātari chromatography.
Ka taea te whakamahi hei kaihoko tango fluorinating mō te wai inu he nui te fluorine (he nui te kaha tango fluorinating), hei kaihoko tango fluorinating mō ngā alkane e rere ana i roto i te hanga alkylbenzene, hei kaihoko tango waikawa me te whakaora mō te hinu whakawhiti, hei kaihoko whakamaroke mō te hau i roto i te umanga hanga hāora, te umanga kakahu me te umanga hiko, hei kaihoko whakamaroke mō te hau taputapu aunoa, me te kaihoko whakamaroke me te kaihoko purenga i roto i te tongi matū, te whakamaroke petrochemical me ētahi atu umanga.
