White powder Calcium Hydroxide 1305-62-0 slaked lime for Use in Acid Wastewater, Sewage Treatment, Boiler Flue Gas Desulfurization
calcium hydroxide product introduction:
1. Nicknames of calcium hydroxide: slaked lime, hydrated lime
2. The main component of calcium hydroxide :Ca(OH)2, molecular weight 74.8
3. Production method of calcium hydroxide: The finished product is obtained by digesting calcium oxide with water and drying, sifting and windpicking.
4. Physical and chemical properties of calcium hydroxide: strongly alkaline. Placed in the air, it gradually absorbs carbon dioxide and becomes calcium carbonate. Slightly soluble in water, soluble in acid. With a density of 22.4g/cm3, its clarified aqueous solution is a colorless odorless alkaline transparent liquid with a PH value of 12.4
