Applications of Caustic Soda 98% Flakes
🧪 Chemical Manufacturing
Caustic soda is a key raw material for producing a wide range of chemicals, including sodium hypochlorite, sodium phosphate, dyes, and solvents. It plays a central role in chemical synthesis, neutralization reactions, and pH regulation.
🧼 Soap and Detergent Industry
Widely used in soap making, caustic soda reacts with fatty acids in the saponification process to produce solid and liquid soaps. It is also used in detergents and household cleaners for grease cutting and stain removal.
🧵 Textile Industry
In textiles, Sodium Hydroxide is used for scouring, bleaching, and dyeing processes. It improves fiber absorbency and enhances color brightness and uniformity in fabrics.
🚰 Water Treatment
Caustic soda is utilized to neutralize acidic water, adjust pH levels, and remove heavy metals during industrial and municipal water treatment processes.
🛢️ Petroleum and Oil Refining
Used to refine petroleum products, caustic soda helps remove sulfur and acidic contaminants, improving the quality of end products like gasoline and lubricants.
