Key Applications of Sodium Hydroxide Lye 50%
1. Chemical Manufacturing
Used as a key raw material in the production of numerous chemicals, including sodium hypochlorite, sodium carbonate, and various surfactants.
2. Water Treatment
Caustic soda helps in neutralizing acidic water, adjusting pH levels, and treating heavy metals, phosphates, and organic waste in wastewater treatment plants.
3. Soap and Detergent Industry
It plays a vital role in saponification, the process of converting fats and oils into soap. It also helps in cleaning, refining, and removing impurities from raw materials.
4. Pulp and Paper Industry
Used in pulping wood, separating lignin from cellulose, and in bleaching processes. It improves fiber quality and brightness in finished paper products.
5. Petroleum and Gas Industry
Sodium hydroxide lye is used to remove sulfur compounds from petroleum and natural gas. It also aids in the refining and processing of fuels.
6. Metal Cleaning and Processing
Acts as a strong degreasing agent in metal fabrication. It removes oil, rust, and scale from surfaces prior to galvanizing or electroplating.
