Premium Hydrated Lime for Chemical Manufacturing – SHC

SHC Hydrated Lime (Calcium Hydroxide, Ca(OH)₂) is a high-purity chemical-grade lime used as a key raw material in the production of various industrial and specialty chemicals. With consistent composition, fine particle control, and excellent reactivity, SHC Hydrated Lime ensures stable performance and high yield in chemical manufacturing.

Applications in Chemical Production

SHC Hydrated Lime is widely used as a base chemical and reactive agent in the synthesis of many important industrial chemicals, including:

1. Calcium-Based Chemicals

• Calcium chloride (CaCl₂): Produced by reacting hydrated lime with hydrochloric acid.

• Calcium nitrate [Ca(NO₃)₂]: Formed from hydrated lime and nitric acid.

• Calcium stearate: Used as a lubricant, stabilizer, and water repellent in plastics and rubber.

• Calcium hypochlorite [Ca(OCl)₂]: Commonly known as bleaching powder or pool disinfectant.

• Precipitated calcium carbonate (PCC): Produced by reacting lime with carbon dioxide, used in paper, plastics, and paints.

2. Water & Wastewater Treatment Chemicals

• Neutralization and pH control: Hydrated lime is used to treat acidic waste streams.

• Flocculant production: Aids in removing heavy metals and phosphates during treatment processes.

• Coagulant preparation: Combined with alum or ferric salts to enhance sedimentation.

3. Inorganic Chemical Processes

• Soda ash (Na₂CO₃) production: As part of the causticization step in the Solvay process.

• Magnesium oxide recovery: Reacts with brines containing Mg²⁺ ions.

• Zinc, nickel, and copper refining: Used for neutralization and impurity removal in leaching solutions.

4. Organic & Specialty Chemical Production

• Citric acid purification: Used to adjust pH and remove impurities during refining.

• Glycerin production: Neutralizes fatty acids in saponification processes.

• Latex and rubber compounding: Improves pH stability and filler dispersion.

• Pharmaceutical intermediates: Acts as a neutralizing agent or calcium source in chemical synthesis.

Key Advantages of SHC Hydrated Lime

• High Ca(OH)₂ purity (90–96%) – consistent and low in Fe₂O₃, SiO₂, MgO impurities.

• Excellent reactivity – rapid dissolution and high neutralizing capacity.

• Controlled fineness – improves mixing and reaction efficiency.

• Low moisture & dust – safer handling and better process control.

• Reliable supply chain – stable production, customized packing, and COA provided for every batch.
