High Purity Hydrated Lime Ca(OH)2 anhydrous Calcium Hydroxide Slaked Lime

1. Water Treatment: Hydrated lime is used in water treatment processes to adjust pH levels, soften water, and remove impurities. It reacts with acidic substances and metal ions, neutralizing acidity and precipitating dissolved contaminants for easier removal during the treatment process.

2. Soil Stabilization: In agriculture and construction, hydrated lime is employed for soil stabilization to improve soil structure and reduce plasticity. It helps enhance soil compaction, stability, and load-bearing capacity, making it suitable for road construction, foundation stabilization, and erosion control.

3. pH Regulation: Hydrated lime is utilized in various industrial processes to regulate pH levels. It is added to acidic solutions or wastewater streams to neutralize acidity and maintain optimal pH conditions for chemical reactions, product quality, and environmental compliance.

4. Construction: In the construction industry, hydrated lime is used as an additive in mortar, plaster, and concrete to improve workability, durability, and cohesion. It helps reduce shrinkage cracking, enhances bond strength, and promotes the formation of calcium silicate hydrates, contributing to the overall performance of construction materials.

5. Environmental Applications: Hydrated lime is utilized in environmental applications such as flue gas desulfurization (FGD) to remove sulfur dioxide (SO2) emissions from industrial exhaust gases. It reacts with sulfur dioxide to form calcium sulfite and calcium sulfate, which can be easily captured and disposed of, reducing air pollution and acid rain formation.

 Characteristics: 

1. Chemical Stability: Hydrated lime is chemically stable under normal conditions.

2. Alkalinity: It is highly alkaline, with a pH of around 12-12.5 when mixed with water, making it effective for neutralizing acids and adjusting pH levels in various processes.

3. Solubility: Hydrated lime is sparingly soluble in water, forming a suspension or slurry rather than a true solution.

4. Reactiveness: It is reactive with acids, undergoing neutralization reactions to form salts and water.

5. Absorption: Hydrated lime can absorb water and carbon dioxide from the atmosphere, gradually converting back to calcium carbonate (limestone) over time, a process known as carbonation.

6. Whiteness: It typically appears as a white, powdery solid.

7. Hygroscopicity: Hydrated lime has some hygroscopic properties, meaning it can absorb moisture from its surroundings.

8. Calcium Source: It serves as a source of calcium ions, which can be beneficial for various applications, including soil amendment and water treatment.

9. Non-flammable: Hydrated lime is non-flammable.

10. Versatility: It finds application in a wide range of industries, including construction (as a component of mortar and plaster), water treatment, agriculture (as a soil amendment), chemical synthesis, and environmental remediation.
