Description

Calcium Hydroxide Hydrate is a versatile inorganic compound widely used as a pH regulator and chemical reagent. Its high reactivity and alkalinity make it a critical component in numerous industrial processes, from water treatment to construction. Key industries that rely on this material include environmental management, building materials, chemical manufacturing, and food processing. We supply high-purity grades to meet the stringent demands of global B2B customers.

Application

• Water Treatment & Flue Gas Desulfurization: Acts as a neutralizing agent and softener for acidic wastewater and exhaust gases.
• Construction (Mortar & Plaster): A key ingredient in traditional lime mortars and plasters for its binding properties.
• Chemical Manufacturing: Used as a precursor and pH adjuster in the production of calcium stearate, other calcium salts, and various organic compounds.
• Food Industry (FCC Grade): Employed as a processing aid, pH control agent, and firming agent in products like pickles and sugar refining.
• Pulp & Paper Production: Utilized in the kraft process for pulp digestion and as a causticizing agent.
• Soil Stabilization & Agriculture: Applied to adjust soil pH (liming) and improve soil structure for crop cultivation.
• Waste Treatment: Effective in sludge stabilization and odor control in municipal and industrial waste handling.
• Pharmaceutical & Personal Care: Used in certain antacid formulations and as an ingredient in depilatory creams.

Quality Control

Our Calcium Hydroxide Hydrate is manufactured under strict quality management systems. We offer various grades, including Industrial, Food (FCC), and high-purity grades, each meeting relevant industry specifications. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metal content, and particle size are available for every batch upon request, ensuring full traceability and compliance for your applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in original, moisture-proof packaging to prevent caking and degradation. Keep away from incompatible materials such as strong acids.
