Meelaha loo adeegsado alumina-da firfircoon waxay inta badan yihiin goobta nuugista iyo goobta kicinta.
1. Codsiga alumina firfircoon ee goobta nuugista
Iyada oo ah nuuge, waa mid ka mid ah ISTICMAALKA ugu muhiimsan ee alumina firfircoon, taas oo inta badan sabab u ah baaxadda dusha sare ee weyn, qaab-dhismeedka daloolka macquulka ah, sifooyinka jireed ee wanaagsan, xasilloonida kiimikada wanaagsan iyo arrimo kale oo badan oo wanaagsan. Codsiyada warshadaha ee muhiimka ah waxaa ka mid ah gaaska qalajinta, dareeraha qalajinta, nadiifinta iyo daaweynta biyaha, iyo nuugista xulashada warshadaha batroolka.
2 codsi oo ah alumina firfircoon marka la qalajinayo gaaska
Sababtoo ah alumina firfircoon iyo biyuhu waxay leeyihiin xiriir xooggan, sidaa darteed aad bay ugu xoog badan tahay awoodda qalajinta biyaha ee gaaska, marka loo eego warshadaha, calcium chloride, silica jel, awoodda qalajinta calcium oxide way ka hooseeyaan alumina firfircoon, awoodda qalajinta barium oxide kaliya ayaa wax yar ka sarreysa alumina firfircoon. Isla mar ahaantaana, sababtoo ah xasilloonida kiimikada ee alumina waa wanaagsan tahay, qayb yar oo ka mid ah gaaska waxayna leedahay falcelin kiimiko ah, sidaa darteed waxay qalajin kartaa noocyo badan oo gaas ah aad bay u badan tahay, suugaanta ayaa soo bandhigtay inay qalajin karto acetylene, hydrogen, oksijiin, hawada, nitrogen iyo in ka badan 20 nooc oo gaas ah.
3. Codsiga alumina firfircoon ee qalajinta dareeraha
Qallajinta dareeraha ah aad bay uga dhib badan tahay qallajinta gaaska, shuruudaha qalajintana waa kuwo aad u sarreeya. Marka hore, falcelinta kiimikada ma dhici karto inta u dhaxaysa qaybaha dareeraha ama inta u dhaxaysa dareeraha iyo nuugaha oksijiinta marka dareeruhu la xiriiro nuugaha. Waqtigan xaadirka ah, waxaa la caddeeyay in dareerayaasha ay qalajin karto alumina ay yihiin hydrocarbons udgoon oo caadi ah, alkenes macromolecular, gaaska, gaaska, iwm.
4. Adeegsiga alumina firfircoon ee goobta kicinta
Habab badan oo warshadeed oo kiciya kicinta lafteeda looma isticmaalo sidii kiciyaha, alumina iyo si ballaaran ayaa loo isticmaalaa sida qaadaha qaybta firfircoon ee kiciyaha, iyo, iyadoo la horumarinayo habka sameynta side-ka kiciyaha alumina ee firfircoon, habab kala duwan ayaa loo isticmaalaa warshadaha side-ka kiciyaha, sida habka xannibaadda, habka granulating, isku-darka, habka tuujinta kubbadda iyo wixii la mid ah, sidaas darteed, waxay noqon kartaa qaabab kala duwan side-ka kiciyaha.
