Production Process: Caustic soda flakes are produced through the electrolysis of salt brine (sodium chloride solution). The process involves:

1. Brine Preparation: Purification of raw brine to remove impurities.

2. Electrolysis: Passing electric current through the brine in electrolytic cells, producing chlorine gas, hydrogen gas, and sodium hydroxide solution.

3. Concentration: Evaporating water from the sodium hydroxide solution to achieve desired concentration.

4. Flaking: Cooling and solidifying the concentrated sodium hydroxide into flakes.

5. Packaging: Ensuring proper packaging to prevent moisture absorption and contamination.

Applications:

1. Chemical Industry: Used as a key ingredient in the manufacturing of various chemicals such as detergents, soaps, and paper.

2. Water Treatment: Utilized to adjust pH levels and treat water for industrial and municipal purposes.

3. Textile Industry: Employed in the textile industry for dyeing, mercerizing cotton, and scouring.

4. Petroleum Industry: Applied in refining petroleum products and drilling mud.

5. Food Industry: Acts as a cleaning agent and peeling agent for fruits and vegetables.

6. Other Uses: Also used in the production of alumina, biodiesel, and in the manufacture of glass and ceramics.

Safety Information: Caustic soda flakes are highly corrosive and can cause severe burns upon contact with skin or eyes. It is crucial to handle the product with appropriate personal protective equipment, including gloves, goggles, and protective clothing. Proper storage in a dry, cool place is essential to prevent moisture absorption and degradation of product quality.
