Alumina whakahohe

Ko te alumina whakahohe (te tātai ngota Al2O(3-x)(OH)2x,0 < x < 0.8) tētahi o ngā hua matū kore-waro e whakamahia whānuitia ana i te ao. Nā tōna hanganga porous, te horahanga mata motuhake teitei me te āhua whakawhiti kore pumau, he nui ake te mahi a te alumina whakahohe. He whānuitia te whakamahinga hei kawe whakatere me te kawe whakatere i roto i te umanga matū hinu me te umanga tongi. He āhuatanga mimiti te alumina whakahohe, nō reira ka whakamahia hei whakamaroke mō te hau me te wai, hei mimiti mō te purenga hau, hei kaihoko tango fluorination mō te wai inu, hei kaihoko whakakore tae me te haunga mō te paru ahumahi, me ētahi atu. I tēnei wā, ko ngā hua alumina whakahohe ahumahi matua ka whakaputaina mā te whakamaroke tere. Ko te alumina whakahohe e pā ana ki te alumina kua whakapūkarahia kua hurihia katoatia, ā, ko te nuinga he mea tito mai i te (20%-90%) alpha-al2o3 me te rahi tioata taketake o te 1 micron. Tātai: Al2O3, Taumaha Ngota: 101.96.

He whānuitia te whakamahinga o te alumina whakahohe i roto i ngā matū hinu, te whakamahine hinu, ngā hikohiko, te ethylene, te propylene, te hau me ētahi atu taputapu whakamaroke, kua whakamahia i roto i te maha o ngā tipu hauwai waikura, ngā tipu tongi, ngā tipu hāora me ngā waeine whakamahine matū hinu, ā, kua tutuki ngā hua pai. Ko te pōro alumina whakahohe hoki, e ai ki te kaha o te wai, te waikura, te waikawa acetic, te kawakore me ētahi atu hononga kaha, he whakamaroke hohonu makuku, he adsorbent o ngā ngota polar adsorbent. Ka taea te whakamahi whānuitia i roto i te whakamaroke hohonu o te hau pakaru hinu, te hau ethylene propylene, te hanga hauwai, te taputapu wehenga hau, te mīhini whakamaroke hau taputapu, te maimoatanga fluoride i roto i te hauwai waikura, ka taea hoki te tango i te hauwai whanariki, te hauhā waro, te hauwai waikura, ngā hauwai warowaihā me ētahi atu poke i roto i te hau para, he mea tino pai mō te wai kei roto te fluorine.

He mā, he iti rānei te porowhita o te alumina hohe, he whero moroiti, he nui ngā stoma huruhuru hipi, he nui ake te mahi, he pai te whakahaere i te wai fluorine teitei, he ngāwari te whakaora, he iti te ihirangi pokanoa, haunga te hunga e whakamahi ana i te wai inu, i tua atu i te mahi fluorine, ka taea tonu te whakamahi hei adsorbent, desiccant me te kawe whakakorikori. He whānuitia te whakamahinga i roto i te hangarau wai tap, te hangarau purenga wai, te tipu hauwai peroxide, te tipu tongi, te tipu hāora me te umanga petrochemical. He āhuatanga adsorption te alumina whakahohe, he kaha whakakorikori porous, he nui te marara, he nui te rohe motuhake o te alumina, he pai mō te momo whakamaroke hau me te wai, ka taea te whakamahi mō te tango wai me ngā taputapu ahumahi, te tango fluorination, te dearsenization, te tango tae paru, te tango haunga me ētahi atu. He mea hanga tēnei hua mai i te alumina parakore teitei mā te whakarite pūtaiao me te whakaotinga whakakorikori. Ka whakamahia hei adsorbent, desiccant, whakakorikori me te kawe i roto i te maha o ngā tukanga tauhohenga pēnei i te hinu, te tongi matū me te umanga matū. E ai ki ana WHAKAMAHINGA ka taea te wehewehe ki: te adsorbent alumina whakahohe, te desiccant me te kawe whakakorikori.

He mea hanga te alumina whakahohe mai i te alumina parakore teitei mā te whakarite pūtaiao me te whakaotinga whakaterenga. He ma ngā matūriki porowhita ma, he rite te rahi o te matūriki, he maeneene te mata, he kaha miihini, he kaha te hygroscopicity, i muri i te mimiti wai, kāore e whānui, kāore hoki e pakaru ngā hua taketake, kāore he paitini, kāore he reka, kāore he kakara, kāore e rewa i roto i te wai me ngā whakarewa waro. He adsorbent ngota me te horahanga mata motuhake nui. Ina iti te uara PH me te kawakore o te wai mata, he teitei ake te kaha tango fluorine i te 3.0mg/g. Ka taea te whakamahi i roto i te wai inu me ngā taputapu ahumahi defluorination, dearsenic, decolorization paru, deodorization, me ētahi atu. Ko ngā hua matua ko: tango fluoride alumina whakahohe, desiccant alumina whakahohe, catalyst alumina whakahohe, alumina whakahohe motuhake hauwai peroxide.

Whakamaroke alumina whakahohe: he momo rauemi porowhita, he moroiti tēnei hua, he kaha te mahi mimiti, he whānui te horahanga mata motuhake, he pakeke te pēhanga, he roa te ora mahi, ā, ka taea te whakamahi anō mā te tikanga whakaora. He ma tēnei hua, he rauemi porowhita, kāore he paitini, kāore he kakara, kāore he paura, kāore e rewa i te wai. He whānui te whakamahinga i roto i te umanga petrochemical, te umanga matū, te umanga kakahu, te umanga koura me ētahi atu ahumahi, pērā i te whakamaroke hau, te taputapu wehewehe hau mimiti pēhanga, ka taea e te tohu tomairangi mimiti te eke ki runga ake i te -41 nekehanga, ka taea hoki te whakamahi mō te maitai, te hau pakaru hinu, te ethylene, te propylene i roto i te wāhanga wai me te whakamaroke hohonu i te wāhanga hau.
