The Structural Properties OfActivated Alumina
Activated alumina ine hunhu hwehukuru adsorption kugona, hombe chaiyo yenzvimbo, simba repamusoro, uye yakanaka kugadzikana kwekupisa.substance.Iyo ine hukama hwakasimba, isiri-chepfu, isiri-corrosive inoshanda desiccant, uye yayo static kugona kwakakwirira.Inoshandiswa se adsorbent, desiccant, catalyst uye mutakuri mune dzakawanda maitiro maitiro akadai se petroleum, kemikari fetiraiza uye indasitiri yemakemikari.
Activated alumina ndeimwe yeanonyanya kushandiswa inorganic makemikari zvigadzirwa munyika.Zvinhu zvealuminium activated zvinotsanangurwa pasi apa: Activated alumina ine kugadzikana kwakanaka uye yakakodzera se desiccant, catalyst carrier, fluorine kubvisa agent, pressure swing adsorbent, inokosha yekuvandudza hydrogen peroxide, etc. Activated alumina inoshandiswa zvakanyanya. se catalyst uye catalyst mutakuri.
Activated alumina inoshandiswa se desiccant, inonyanya kushandiswa mumaindasitiri emhepo air pressure drying equipment, air pressure drying equipment ine simba rekushanda, kazhinji pazasi 0.8Mpa, inoda iyo activated alumina ratio kuti ive nesimba rakanaka remuchina, kana simba remuchina ranyanya. yakaderera, iri nyore kuita hupfu, hupfu uye kusanganiswa kwemvura kuchavhara zvakananga pombi yemidziyo, saka, Chiratidzo chakakosha chealumina yakagadziriswa inoshandiswa se desiccant isimba, mhepo yekuomesa midziyo yekuomesa, kazhinji matangi maviri, matangi maviri anoshanda zvakasiyana, ndizvo chaizvo. a adsorption saturation → analytic cycle process, desiccant inonyanya kushambadza mvura, asi pasi pemamiriro ekushanda echokwadi, mhepo yekuomesa mhepo midziyo inobva mweya ichava nemafuta, ngura uye kumwe kusvibiswa, Izvi zvinhu zvinokanganisa zvakananga hupenyu hwebasa re activated alumina adsorbent, nokuti inoshandiswa. alumina is porous adsorption material, natural adsorption polarity yemvura, mafuta adsorption yakanakirawo, asi oiri inovhara yakananga activated alumina adsorption pore, kuitira kuti kurasikirwa kweadsorption hunhu, kuve ne ngura, ngura mumvura, yakanamirwa pamusoro pe. activated alumina, Ichaita activated alumina zvakananga kurasikirwa basa, saka mu activated alumina se desiccant kushandiswa, edza kudzivisa kusangana nemafuta, ngura, activated alumina adsorbent sezvo desiccant general kushandiswa upenyu 1 ~ 3 makore, kushandiswa chaiko kuchava kuomesa gasi. dova rinoratidza kusarudza kana kutsiva activated alumina.Iyo tembiricha yekuvandudza yealumina yakagadziriswa iri pakati pe180 ~ 350 ℃.Kazhinji, iyo yakagadziriswa alumina tower tembiricha inokwira kusvika 280 ℃ kwe4 maawa.Activated alumina inoshandiswa semvura yekurapa mumiririri, uye aluminium sulfate mhinduro inoshandiswa seyakagadziridza.Mushonga wekugadzirisa aluminium sulfate regenerator ndeye 2 ~ 3%, iyo yakagadziriswa alumina mushure mekudsorption saturation inoiswa mualuminium sulfate solution soaking, kurasa mhinduro, geza nemvura yakachena 3 ~ 5 nguva.Mushure mekushandiswa kwenguva refu, iyo yakagadziriswa alumina pamusoro ine yellowish brown uye iyo defluorination mhedzisiro inoderedzwa, iyo inokonzerwa nekushambadza kwetsvina.Inogona kurapwa ne 3% hydrochloric acid kwekanguva kamwechete uye yobva yadzorerwa nenzira iri pamusoro.
