Maaddada ceeriin ee ugu weyn ee alumina desiccant-ka firfircoon waa budada aluminium hydroxide ee heerka warshadaha, taas oo ah nooc ka mid ah oksaydhka aasaasiga ah oo leh 3-5% biyo ku jira, iyo hoos u dhaca gubashada alumina hydroxide ee 900-1100 ℃ waa 34.5%.
Habka wax soo saarka ee alumina desiccant-ka firfircoon waa sida soo socota:
Aluminium hydroxide - qalajin - warshad ilaa 600 mesh, aluminium hydroxide 300 ℃ fuuqbax degdeg ah - qaabaynta saxanka - daaweyn firfircooni 12 saacadood ah - iyada oo loo marayo foornada shaft 550 ℃ sintering.
1. Budada aluminium hydroxide ee warshadaha, oo ka kooban qoyaan 3-5% ah, ayaa lagu qalajiyaa 120℃ iyadoo la adeegsanayo qalab qalajin oo waaweyn.
2. Ka dib marka la qalajiyo, budada aluminium hydroxide waxay gashaa shiidid farsamo oo waaweyn waxayna burburisaa ilaa 600 oo bir ah. Inta ay jilicsan tahay, ayay u wanaagsan tahay in loo qaabeeyo habka kicinta kubbadda. Walxaha wareegsan ee la soo saaray ma laha budo iyo xoog sare.
3, budada aluminium hydroxide, oo geli nidaamka kala-goynta degdega ah ee loogu talagalay sintering-ka bilowga ah, budada aluminium hydroxide ee fiican ee socodka hawada kulul ee aadka u kacsan waxay ku sii jirtaa 0.10s, mabda'a wax soo saarka waa: aluminium hydroxide iyadoo la shiilayo fuuq-baxa degdega ah, iyo qaboojinta degdega ah.
4, iyadoo la adeegsanayo mabda'a kubbadda barafka, soo saarista kubbadda alumina ee firfircoon, habkan waxaa laga samayn karaa dhexroor kala duwan oo ah alumina desiccant iyo side.
5, kubbadda walxaha alumina ee firfircoon waxay socon kartaa 12 saacadood, kulaylkeeda iyo biyo u gaar ah ayaa la dhaqaajin karaa.
6. Ugu dambeyntii, alumina-da firfircoon waxaa lagu shubaa foorno toosan, heerkulka dubana waa 550-700℃.
