Pēke whatu 25kg/pahu pepa 25kg/pahu rino 200L, i runga rānei i te tono a te kiritaki.
Ngā Āhuatanga Hanganga oArumina Whakahohe
Ko ngā āhuatanga o te alumina whakahohe he nui te kaha mimiti, he nui te horahanga mata motuhake, he kaha teitei, ā, he pai te pumau o te wera. He kaha te hononga, he kore-paitini, he kore-waikura te whai hua o te whakamaroke, ā, he teitei tōna kaha pumau. E whakamahia ana hei mimiti, hei whakamaroke, hei whakakorikori me te kawe i roto i ngā tukanga tauhohenga maha pēnei i te hinu, te tongi matū me te ahumahi matū.
Ko te alumina whakahohe tētahi o ngā hua matū kore-waro e whakamahia whānuitia ana i te ao. Kei raro nei ngā āhuatanga o te alumina whakahohe: He pai te pumau o te alumina whakahohe, ā, he pai hei whakamaroke, hei kawe whakakorikori, hei tango i te fluorine, hei mimiti pēhanga, hei kaihoko whakaora motuhake mō te hauwai waikura, me ētahi atu. He whānuitia te whakamahinga o te alumina whakahohe hei whakakorikori me te kawe whakakorikori.
Ko te alumina whakahohe ka whakamahia hei whakamaroke, ko te nuinga e whakamahia ana i roto i ngā taputapu whakamaroke pēhanga hau ahumahi, ko te pēhanga mahi a ngā taputapu whakamaroke pēhanga hau, ko te tikanga kei raro iho i te 0.8Mpa, e hiahia ana kia pai te ōwehenga o te alumina whakahohe kia kaha te miihini. Ki te iti rawa te kaha miihini, he ngawari ki te paura, ka aukati tika te whakakotahitanga paura me te wai i te paipa taputapu, nō reira, Ko te tohu nui o te alumina whakahohe e whakamahia ana hei whakamaroke ko te kaha, ko te taputapu whakamaroke pēhanga hau, ko te tikanga e rua ngā tāke, e rua ngā tāke e mahi tahi ana, ko te tikanga he tukanga huringa tātaritanga adsorption → adsorption, ko te desiccant te nuinga o te adsorption wai, engari i raro i ngā āhuatanga mahi pono, ka whai hinu, waikura me ētahi atu poke te pūtake o te taputapu whakamaroke pēhanga hau. Ka pā tika ēnei āhuatanga ki te roa o te mahi o te adsorbent alumina whakahohe, nā te mea he rauemi adsorption porous te alumina whakahohe, he polarity adsorption taiao o te wai, he tino pai hoki te adsorption hinu, engari ka mono tika te hinu i te pore adsorption alumina whakahohe, kia ngaro ai ngā āhuatanga adsorption, ka waikura, ka piri ki te mata o te alumina whakahohe, ka ngaro tika te mahi a te alumina whakahohe, nō reira I roto i te whakamahinga o te alumina whakahohe hei whakamaroke, ngana kia kaua e pā ki te hinu, ki te waikura rānei. Ko te roanga whakamahinga whānui o te whakamahi i te alumina whakahohe hei whakamaroke ko te 1 ~ 3 tau, ko te whakamahinga tūturu ko te whakamaroke i te hau hau hei whakatau mēnā me whakakapi te alumina whakahohe. Ko te pāmahana whakaora o te alumina whakahohe kei waenganui i te 180 ~ 350℃. Ko te tikanga, ka piki te pāmahana o te pourewa alumina whakahohe ki te 280℃ mō te 4 hāora. Ka whakamahia te alumina whakahohe hei rongoā wai, ā, ka whakamahia te otinga konumohe whanariki hei whakaora. Ko te kukū o te otinga o te konumohe whanariki whakaora he 2 ~ 3%, i muri i te mimiti o te alumina whakahohe ka rumakina ki te otinga konumohe whanariki, ka maka te otinga, ka horoia ki te wai ma 3 ~ 5 ngā wā. I muri i te whakamahinga roa, ka parauri te mata o te alumina whakahohe, ā, ka heke te pānga mimiti, nā te mimiti o ngā poke i puta. Ka taea te rongoa ki te waikawa hauwai 3% mō te wā kotahi, kātahi ka whakaorahia mā te tikanga i runga ake nei.
