1.Molecular formula: Ca(OH)2
2.Molecular weight: 74.096
3.Physical and chemical properties: Soft fine white powder, density 2.24, bulk density 0.5-0.8. At 580℃, it loses the binding water and becomes calcium oxide. Exposed to the air, it can gradually absorb carbon dioxide and become calcium carbonate, which is soluble in acid, slightly soluble in water, and insoluble in alcohol.
4.Features: This product has high activity, loose structure, high effective calcium hydroxide content, good whiteness (whiteness ≥94 degrees), fine, harmful metal content is very low, dust, black spots are very few, was rated as provincial new products.
5.To use: he product is widely used in the synthesis of calcium stearate, calcium naphthenate, calcium lactate, calcium citrate and other high-grade organic chemical synthesis and water treatment fields.
