About Hydrated Lime (Calcium Hydroxide)
Hydrated Lime, chemically known as Calcium Hydroxide (Ca(OH)₂), is an inorganic chemical compound presented as a dry, white powder or fine granules. It is produced by adding water to quicklime (calcium oxide), initiating a highly exothermic hydration reaction. Supplied at a typical purity level of 90-95%, this product has a strongly alkaline nature with a pH of saturated solution ranging approximately from 12.4 to 12.6. Hydrated Lime is sparingly soluble in water, forming a milky suspension known as limewater. For industrial procurement, it is crucial to confirm moisture content and particle size distribution as these impact handling and application effectiveness. The compound reacts with acidic substances and carbon dioxide during use, making it incompatible with materials such as strong acids and ammonium salts, which can release ammonia gas upon contact. Handling temperatures should avoid extremes to maintain product stability and prevent agglomeration.
Why Hydrated Lime (Calcium Hydroxide) Matters
Hydrated Lime addresses critical challenges in water and wastewater treatment by effectively neutralizing acidity and precipitating metals, thus ensuring regulatory compliance and environmental safety. In construction, it enhances soil bearing capacity and durability of mortars, preventing costly structural failures and maintenance. Its high alkalinity and reactivity enable transformative effects such as sulfur dioxide gas removal in flue gas treatment, directly contributing to emission reduction efforts. These precise chemical interactions provide measurable improvements in operational processes, avoiding hazardous byproducts and enhancing product lifespan.
