Alumina firfircoon

Alumina firfircoon (qaacidada molecular Al2O(3-x)(OH)2x,0

Alumina-da firfircoon waxaa si weyn loogu isticmaalaa batroolka kiimikada, sifeynta saliidda, elektarooniga, ethylene, propylene, hawada iyo aaladaha kale ee qalajinta, waxaa loo isticmaalay warshado badan oo hydrogen peroxide ah, warshado bacrimin ah, warshado oksijiin iyo cutubyo sifeyn batroolka ah, waxayna gaartay natiijooyin wanaagsan. Kubbada alumina ee firfircoon sidoo kale iyadoo loo eegayo kala duwanaanshaha nuugista si loo go'aamiyo xoogga biyaha, oksaydhka, acetic acid, alkali iyo xiriir kale oo xooggan, waa qoyaan qoto dheer oo qoyaan ah, nuugista molecules-ka polar-ka. Waxaa si ballaaran loogu isticmaali karaa qallajinta qoto dheer ee gaaska dillaaca batroolka, gaaska ethylene propylene, wax soo saarka hydrogen, qalabka kala soocida hawada, mashiinka qalajinta hawada qalabka, daaweynta fluoride ee hydrogen peroxide, sidoo kale waxay ka saari kartaa hydrogen gaaska sulfur, carbon dioxide, hydrogen fluoride, hydrocarbons iyo wasakheeyayaasha kale ee gaaska qashinka ah, gaar ahaan ku habboon biyaha fluorine-ka ku jira.

Alumina firfircoon waa cad ama yar oo globular ah oo casaan yar ah, waxay leedahay stoma badan oo dhogor ah iyo firfircooni dheer, maaraynta saamaynta biyaha ee fluorine-ka dheer waa wanaagsan tahay, dib u soo noolayn fudud, waxyaabaha faragelinta ku jira waa yar yihiin, marka laga reebo kuwa isticmaala biyaha la cabbo marka laga reebo ficilka fluorine, wali waxay u isticmaali karaan sida nuugista, qalajinta iyo side kicinta. Waxaa si weyn loogu isticmaalaa injineernimada biyaha tuubada, injineernimada nadiifinta biyaha, warshadda hydrogen peroxide, warshadda bacriminta, warshadda oksijiinta iyo warshadaha batroolka. Alumina firfircoon waxay leedahay sifooyin nuugista, firfircoonida catalytic ee daloolada, kala firdhinta sare, aag gaar ah oo weyn oo alumina ah, oo ku habboon noocyo kala duwan oo gaas iyo qalajinta dareeraha ah, waxaa loo isticmaali karaa cabitaanka biyaha iyo qalabka warshadaha deoksidaynta, defluorination, desenization, decolorization, deodorization iyo wixii la mid ah. Badeecadani waxay ka samaysan tahay alumina saafi ah oo sare iyada oo loo marayo diyaarinta sayniska iyo dhammaystirka catalytic. Waxaa loo isticmaalaa sida nuugista, desiccant, kiciye iyo side hababka falcelinta badan sida batroolka, bacriminta kiimikada iyo warshadaha kiimikada. Sida laga soo xigtay ISTICMAALKA waxaa loo qaybin karaa: firfircoon alumina nuugaya, qalajiyaha iyo side kicinta.

Alumina-da firfircoon waxaa laga sameeyay alumina saafi ah oo heer sare ah iyada oo loo marayo diyaarinta cilmiyeed iyo dhammaystirka kicinta. Qaybaha cad ee daloolada wareegsan, cabbirka walxaha isku mid ah, dusha siman, xoogga farsamada, hygroscopicity xooggan, ka dib marka nuugista biyuhu aysan ballaarin oo aysan jabin alaabada asalka ah, kuwa aan sunta ahayn, aan dhadhan lahayn, ur lahayn, aan ku milmin biyaha iyo dareerayaasha dabiiciga ah. Waa nuuge molecular ah oo leh aag dusha sare oo weyn. Marka qiimaha PH iyo alkalinity ee biyaha cayriin ay hooseeyaan, awoodda ka saarista fluorine-ku waxay ka sarreysaa 3.0mg/g. Waxaa loo isticmaali karaa nadiifinta biyaha iyo qalabka warshadaha, dearsenic, nadiifinta wasakhda, furfurista urta, iwm. Badeecadaha ugu muhiimsan waa: ka saarista fluoride-ka alumina ee firfircoon, nadiifinta alumina ee firfircoon, kicinta alumina ee firfircoon, hydrogen peroxide alumina gaar ah oo firfircoon.

Nadiifiyaha alumina ee firfircoon: Badeecadani waa nooc ka mid ah walxo microporous iyo wareegsan, oo leh shaqo nuugid xooggan, baaxad weyn oo dusha sare ah, adkaanta cadaadiska sare, cimri dheer oo adeeg ah, waxaana si isdaba joog ah loogu isticmaali karaa habka dib u soo noolaynta. Badeecadani waa walax cad, dalool wareegsan oo aan sun ahayn, ur lahayn, aan budo lahayn, aan ku milmi karin biyaha. Waxaa si weyn loogu isticmaalaa warshadaha batroolka, warshadaha kiimikada, warshadaha dharka, warshadaha dahabka iyo warshadaha kale, sida qalajinta dabaysha qalabka, qalabka kala soocida nuugista cadaadiska, dhibicda nuugista waxay gaari kartaa in ka badan -41 digrii, sidoo kale waxaa loo isticmaali karaa birta, gaaska dillaaca batroolka, ethylene, propylene marxaladda dareeraha iyo qallajinta qoto dheer ee wejiga gaaska.
