Dulmar guud oo ku saabsan aluminiinta firfircoon
Alumina firfircoon, oo sidoo kale loo yaqaan bauxite firfircoon, waxaa loogu yeeraa alumina firfircoon ee Ingiriisiga. Alumina loo isticmaalo kicinta waxaa badanaa loo yaqaan "alumina firfircoon". Waa wax daloola, shay adag oo aad u kala firdhiyey oo leh dhul ballaadhan. Dusha sare ee microporous waxay leedahay sifooyinka looga baahan yahay catalysis, sida waxqabadka xayeysiinta, dhaqdhaqaaqa dusha sare, xasilloonida kulaylka aad u fiican, iwm.
Xayawaanka saliida lulida cadaadiska alumina ee firfircoon ee wareega ah waa qaybo dalool oo wareegsan oo cad. Alumina firfircooni waxay leedahay cabbirka walxaha isku midka ah, dusha siman, xoogga farsamada sare, hygroscopicity xoog leh, ma bararto oo dillaaco ka dib nuugista biyaha, oo weli isbeddelin. Waa wax aan sun ahayn, ur lahayn, oo aan lagu milmi karin biyaha iyo ethanol.
Alumina
Kuma milmi karaan biyaha waxayna si tartiib ah ugu milmi kartaa sulfuric acid. Waxaa loo isticmaali karaa in lagu sifeeyo aluminiumka birta ah sidoo kale waa walxo ceeriin ah oo lagu sameeyo weel, dhoobo, alaab celin iyo dhagaxyo macmal ah.
Alumina loo isticmaalo sida adsorbent, kicinta iyo xambaarka xambaara waxaa loo yaqaan "alumina firfircoon". Waxay leedahay sifooyinka porosity, kala firidhsan sare iyo bed gaar ah oo weyn. Waxaa si weyn loogu isticmaalaa daaweynta biyaha, petrochemical, kiimiko wanaagsan, bayooloji iyo beeraha dawooyinka.
Astaamaha alumina
1. Meel sare oo gaar ah oo weyn: alumina firfircooni waxay leedahay meel sare oo gaar ah. Iyadoo si macquul ah loo xakameynayo nidaamka sintering ee alumina, alumina firfircoonida leh oo leh meel gaar ah oo sare oo ah 360m2 / G ayaa la diyaarin karaa. Alumina-da firfircoon ee loo diyaariyey iyadoo la adeegsanayo kolloidal aluminium hydroxide oo ay burburisay NaAlO2 sida alaabta ceeriin waxay leedahay cabbir dalool oo aad u yar iyo meel gaar ah oo sare oo ah 600m2 / g.
2. Qaab dhismeedka cabbirka daloolka la isku hagaajin karo: Guud ahaan, alaabada leh cabbirka daloolka dhexdhexaadka ah waxaa lagu diyaarin karaa iyadoo lagu dubayo aluminium hydroxide saafi ah. Alaabooyinka cabbirka daloolada yaryar waxaa lagu diyaarin karaa iyadoo la diyaarinayo alumina firfircoon oo leh xabag aluminium ah, iwm. halka cabbirka daloolada waaweyn ee firfircoonida alumina la diyaarin karo iyadoo lagu darayo walxaha organic qaarkood, sida glycol ethylene iyo fiber, gubashada ka dib.
3. Dusha sare waa aashito waxayna leedahay xasilooni kulayleed wanaagsan.
Shaqada aluminium firfircoon
Alumina firfircooni waxay ka tirsan tahay qaybta alumina kiimikada, taas oo inta badan loo isticmaalo sida adsorbent, nadiifiyaha biyaha, kicinta iyo qaadaha kicinta. Alumina firfircooni waxay awood u leedahay inay si xushmad leh ugu darsato biyaha gaasta, uumiga biyaha iyo dareerayaasha qaarkood. Ka dib markii adsorption-ku buuxsamo, waxaa lagu kululayn karaa qiyaastii 175-315. D eg. Adsorption iyo dib u kicinta ayaa la samayn karaa marar badan.
Marka laga soo tago in loo isticmaalo qallajiye ahaan, waxa kale oo ay ka nuugi kartaa uumiga saliidda ee wasakhaysan ee ogsijiinta, hydrogen, carbon dioxide, gaaska dabiiciga ah, iwm. Waxa kale oo loo isticmaali karaa caawiye kicin iyo taageero iyo taageero falanqaynta chromatographic.
Waxaa loo isticmaali karaa sida wakiilka defluorinating ee biyaha la cabbo fluorine sare (oo leh awood weyn oo defluorinating), wakiilka defluorinating ee wareegga alkylbenzene ee wax soo saarka ee alkylbenzene, wakiilka deacidifying iyo dib u soo celinta saliid transformer, wakiilka qalajinta gaaska ee oxygen samaynta warshadaha. , Warshadaha dharka iyo warshadaha elektarooniga ah, wakiilka qalajinta hawada qalabka si toos ah, iyo wakiilka qalajiyo iyo wakiilka nadiifinta ee bacriminta kiimikada, qalajinta petrochemical iyo warshadaha kale.
