Caustic Soda Flakes 25 Kg Bags Packaging /Industrial Grade In Paper Industry
Product Description
Caustic soda flakes, also known as sodium hydroxide flakes or solid caustic soda, are a highly caustic and versatile inorganic compound. They are solid, white flakes that are widely used in various industrial applications and chemical processes.
Caustic soda flakes are composed of sodium (Na), hydrogen (H), and oxygen (O), with the chemical formula NaOH. They are typically manufactured through the electrolysis of salt, a process known as the chloralkali process. The resulting caustic soda flakes have a high concentration of sodium hydroxide and exhibit strong alkaline properties.
Caustic soda flakes find a wide range of industrial applications. They are commonly used in the production of chemicals such as detergents, soaps, paper, textiles, and various organic compounds. They are also employed in metal processing, petroleum refining, water treatment, and the manufacturing of pharmaceuticals.

Applications in the paper industry
1.Pulping: Sodium hydroxide is used in the pulping process, which is the initial step in paper production. It helps break down wood chips or other raw materials into fibers. Sodium hydroxide, along with other chemicals, is added to the wood chips in a process known as alkaline pulping. This treatment softens and dissolves the lignin, a natural adhesive that holds the wood fibers together. The dissolution of lignin allows for the separation and extraction of the cellulose fibers, which are then used to produce paper.
2.Kraft Cooking: Sodium hydroxide is a key component in the kraft pulping process, which is the most common method for pulping wood. In the kraft cooking process, wood chips are treated with a mixture of sodium hydroxide and sodium sulfide known as white liquor. This treatment breaks down the lignin and separates the cellulose fibers, resulting in a pulp that is suitable for papermaking.
3.PH Adjustment: Sodium hydroxide is used for pH adjustment in various stages of the papermaking process. Controlling pH is crucial for several reasons, such as optimizing the performance of chemicals used in paper production, facilitating the formation of paper sheets, and ensuring proper sizing and coating. Sodium hydroxide is added to adjust the pH of the pulp, the paper machine water, and various chemical solutions involved in the papermaking process.
4.Bleaching: Sodium hydroxide is sometimes used in bleaching processes to brighten and whiten the paper. It is typically employed in conjunction with other bleaching agents, such as chlorine or hydrogen peroxide, to remove impurities, lignin residues, and residual color from the pulp. Sodium hydroxide aids in the activation and effectiveness of these bleaching agents.
5.Waste Treatment: Sodium hydroxide is also used in wastewater treatment within the paper industry. It is employed to neutralize acidic effluents generated during various stages of paper production. By adjusting the pH of the wastewater to a neutral or acceptable range, sodium hydroxide helps in the removal of pollutants and facilitates the treatment and disposal of effluent streams.
