Caustic Soda Flake
Caustic Soda Flake 99%
Caustic Soda Flake or (Sodium hydroxide) is produced commercially by two basic methods: electrolytic cells and chemical processes.
Production Process of Caustic Soda
Caustic soda is produced by reacting sodium carbonate (Na2CO3) with hydrated lime (Ca[OH]2) to form sodium hydroxide (NaOH) and calcium carbonate (CaCO3).
Application of Caustic Soda Flake (Sodium hydroxide)
Caustic Soda Flake Applications in Chemical Industries
Basic chemical industrial production, such as the making of metallic sodium and sodium dichromate, manganese carbonate, and sodium hydrosulfite, and the acid-base neutralization; chemical pesticide industry, such as the organic chemical industry for producing of sodium pentachlorophenol, 1650, and 1059, and the production of organic acid, organic fiber, and organic resin. Common soap is produced by grease which shall be functioned under superfluous caustic soda. So as the refined petroleum and organic composting.
Caustic Soda Flake Applications in Textile Industries
In Textiles Industries, caustic soda flake (lye) is used as chemical fiber making and clothing printing and dyeing. Caustic soda is used in mercerizing and scouring cotton fabrics and fibers. About 90% of all cotton undergoes the scouring treatment, which renders the fabric more absorbent to bleaching agents. Approximately 35% of cotton is mercerized to improve fiber strength and affinity for dyes.
Caustic Soda Applications in Paper and Pulp Industry
Sodium hydroxide is used to help regenerate the chemicals used to pulp the wood chips into fibers in the chemical pulping process, which allows the pulp mill to reuse many of the chemicals and reduce the cost of producing pulp. It is also used in one of the stages of some common bleaching processes to increase the efficiency of the particular stage of the bleaching. Additionally, Caustic Soda is used is in paper recycling. The sodium hydroxide causes the fibers to swell when they are placed in a solution with sodium hydroxide. This swelling helps to separate the ink that is attached to the fibers allowing the fibers to be reused.
Caustic Soda is Used in Several Food Processing Applications
An example is in removing skins from potatoes, tomatoes, and other fruits. For processing edible fats and oils, caustic soda is a must-use material.
Caustic Soda for Controlling pH in Different Industries
The final application of sodium hydroxide is simply for pH control. It is used for this in many processes where the efficiency of the process is affected. In these applications, the goal is to optimize the chemicals being used to save money and make the process more environmentally friendly. For example, when sodium hypochlorite is used as a bleaching chemical, sodium hydroxide is used to help keep the pH as close to 8.0 as possible, because sodium hypochlorite is most effective at that pH.

Other Applications of Caustic Soda
- Pharmaceuticals
- Cosmetics industry and household chemistry for producing detergent, soap, surfactants, washing liquids, and powders, degreasers and water softeners, etc
- In refineries and coking plants, caustic soda is used to modify products derived from coking coal.
- In the steel and metallurgical industries, caustic soda is involved in the process of obtaining aluminum from bauxite processing.
