ã€China Aluminum Network】 calcium aluminate powder is a white powder. The main ingredient is a mixture of calcium dialuminate (CaO·2A1203) and calcium aluminate (CaO·A1203). Slightly soluble in water, aqueous solution is alkaline, PH value is about 11. Calcium aluminate powder and inorganic strong acid reactivity is very high, can start at room temperature. With large heat release and rapid heating, the dissolution rate of alumina can reach over 90%. Using it as raw material to produce liquid or solid PAC can simplify the process, reduce costs, and improve product quality. At present, most of the domestic and foreign polymerized chlorine Raw materials used by aluminum producers.
