Waxay ku qalabaysan tahay marawaxad leh shaqada kala firdhinta.Sidaas darteed waxay ku habboon tahay kulaylka alaabta ceeriin ee xasaasiga ah si gaar ah Mashiinka marawaxada leh xawaaraha sare wuxuu burburin karaa alaabta ceeriin ee qoyan iyo kuwa dillaacsan ilaa ay kala firdhiyaan Inta lagu jiro xilliga kala firdhinta, waa la miiray oo isku qasan .Dabadeed alaabta ceeriin iyo hawadu waxay u socdaan is barbar socda.Waa lagu dabaqi karaa qalajinta alaabta ceeriin ee keega xanniban laakiin qoyaanka dusha oo keliya ka yar 40%.Haddii qadarka la daweynayo uu badan yahay ama qoyaanka looga baahan yahay alaabta la dhammeeyey ay ka yar tahay 60%, laba darajo qalajin ayaa la isticmaali karaa si loo waafajiyo qasiyaha.Iyadoo loo marayo habka isku dhafka alaabta ceeriin ee qalalan si loo yareeyo qoyaanka alaabta ceeriin.Waqtigaan, wadarta wax soo saarka qalajiyaha ayaa aad hoos u dhici doona.Kuma haboona dhaqaalaha.Sidaa darteed macmiilku waa inuu ka saaraa qoyaanka isagoo isticmaalaya habka mishiinada (centrifugal ama press) si loo yareeyo qoyaanka sida ugu macquulsan si loo dammaanad qaado qalajinta qalajinta si xor ah.
Qalabku wuxuu dabooli karaa baahida kala duwan ee alaabta ceeriin.Besides alaabta ceeriin ee ku xusan qaabka aasaasiga ah, waxaa jira hymenal, ABC dhexdhexaad ah, xabagta ABS, madow carbon cad, shaaha, kicinta of oxailc acid, kor u wakiilka mdm, kicinta, dhigaalka budada carbon, N-acetyl-sulfanily chloride, p-aminosalicylic acid, p-phthalic acid, diethyl aniline, titanium dioxide, carbon firfircoon, sodium fluosilicate, ammonium sulphate, budada of xabagta silikon, synthesis resin, calcium sulphate, PP resin, aureomycin, sodium polaysilicate , gulukooska afka, sodium sulphate, mine of sulphate, mine of fosfooraska, BB buluug, dhalaalay bacriminta fosfooraska, tetracycline, ferric oxide, calcium carbonate, titanium / ferric mine, macdanta Copper, budada of baradho cad, dhuxul dabada, stearate, zein, daawo, wakiilka caafimaadka, ferric oxide, lees haraaga iyo wixii la mid ah.
1.qallajiye awood leh,maalgelin yar iyo waxtarka sare ee awoodda uumi-baxa.
2.Short qalajiyaha time.Alaabtii dhammaatay ayaa laga soocay dibadda,iyo wax wasakh ah oo tayo sare leh.
3. Kuleylka waxaa laga dooran karaa uumiga, shidaalka dhuxusha, shidaalka iyo shidaalka gaaska foornada hawada kulul.
