Taupānga/Pake
Ka whakamahia tenei hua mo te whakamaroke hohonu o te hau, te wahanga wai ranei o te petrochemical me te whakamaroke taputapu.
25kg peeke raranga / 25kg pepa papa pahū / 200L pahū rino ranei ia tono a te kiritaki.
The Structural Properties OfAlumina Whakahohe
Ko te alumina kua whakahohehia nga ahuatanga o te kaha adsorption nui, te waahanga mata motuhake, te kaha teitei, me te pai o te waiariki. taonga. He kaha te hononga, he mea paitini kore-paitini, kore-waikura whai hua, a he tiketike tona kaha pateko. Ka whakamahia hei adsorbent, desiccant, whakakōkī me te kawe i roto i te maha o ngā tukanga tauhohenga pērā i te hinu, tongi matū me te ahumahi matū.
Ko te alumina whakahohe tetahi o nga hua matū pararopi e tino whakamahia ana i te ao. Ko nga ahuatanga o te alumina kua whakahoahohia kei raro iho nei: Ko te alumina whakahohe he pai te pumau, he pai hoki hei whakamaroke, hei kawe whakakorikori, hei kaikawe tango fluorine, he peehi piu pehanga, he kaihoko whakahou motuhake mo te hydrogen peroxide, me era atu. hei kaikawe me te kaikawe kawe.
Ko te alumina kua whakahohehia he mea whakamaroke, ko te nuinga o te waa e whakamahia ana i roto i nga taputapu whakamaroke pehanga hau ahumahi, ko nga taputapu whakamaroke o te hau he kaha mahi, i raro iho i te 0.8Mpa, e hiahia ana kia pai te kaha o te kaha o te alumina, mehemea he kaha te kaha o te miihini. iti, he mea ngawari ki te paura, paura me te whakakotahitanga wai ka aukati tika i te pipeline taputapu, na, Ko te tohu nui o te alumina whakahohe whakamahia hei desiccant ko te kaha, nga taputapu whakamaroke pehanga hau, te tikanga e rua nga taika, e rua nga taika e mahi tahi ana, he pono. he waiwai adsorption → tukanga huringa tātari, desiccant Ko te nuinga o te wai adsorption, engari i raro i ngā āhuatanga mahi tūturu, te pēhanga hau whakamaroke taputapu puna hau ka whai hinu, waikura me te tahi atu poke, Ko enei āhuatanga ka pa tika ki te ora ratonga o te whakahohe alumina adsorbent, no te mea kua whakahohehia. konumohe he rauemi adsorption maiengi, polarity adsorption māori o te wai, he tino pai hoki te hinu adsorption, engari ka mono tika hinu whakahohe konumohe adsorption pore, kia te mate o ngā āhuatanga adsorption, he waikura, waikura i roto i te wai, piri ki te mata o konumohe whakahohe, Ka hanga konumohe whakahohe ka ngaro te mahi, na i roto i te konumohe whakahohe hei whakamahi desiccant, ngana ki te karo i te whakapiri ki te hinu, waikura, konumohe whakahoahoa adsorbent hei desiccant te ora whakamahi whanui o te 1 ~ 3 tau, ko te whakamahi tonu hei whakamaroke hau. te toma ki te whakatau mehemea ka whakakapihia te konumohe whakahohe. Ko te pāmahana whakaoranga o te konumohe whakahohe kei waenga i te 180 ~ 350 ℃. Ko te tikanga, ka piki te pāmahana o te pourewa alumina ki te 280 ℃ mo te 4 haora. Ka whakamahia te konumohe whakahohe hei kaihoko maimoatanga wai, ka whakamahia te otinga konumohe sulfate hei kaiwhakaora. Ko te kukū otinga o te konumohe pūkawa ngāwha regenerator ko 2 ~ 3%, te konumohe whakahohe i muri i te waiwai adsorption whakanohoia i roto i te konumohe pūkawa ngāwha otinga waiwai, maka te otinga, horoi ki te wai ma 3 ~ 5 wa. I muri i te whakamahinga mo te wa roa, ko te mata o te alumina kua whakahoahohia he parauri kowhai me te whakaheke i te paanga o te defluorination, na te whakaurunga o nga poke. Ka taea te rongoa ki te 3% waikawa pūhaumāota mo te 1 wa ka whakahouhia e te tikanga o runga ake nei.
