Caustic soda flakes, also referred to as sodium hydroxide flakes, are solid, white materials characterized by a crystalline structure. They exhibit strong hygroscopic properties, meaning they readily absorb moisture from the atmosphere. When dissolved in water, caustic soda flakes completely dissolve, producing a highly corrosive soda lye and generating substantial heat in the process. For businesses and industries, partnering with a reliable caustic soda supplier is essential to ensure the quality and purity of the caustic soda flakes, meeting specific requirements for various applications.
There are few methods of the manufacturing process or how to make caustic flakes, which by metathesis reaction and chloralkali process.
By reacting sodium carbonate with calcium hydroxide, sodium hydroxide, and calcium carbonate is produced. These products can be easily separated by filtration as calcium carbonate is not soluble whereas sodium hydroxide is highly soluble. The solution will then be purified, processed, and standardized for industrial consumption.
With the electrolysis of sodium chloride solution, solid sodium hydroxide is manufactured and obtained with the evaporation of water. Chlorine gas is also produced as the main by-product. This is done through three main types of cells, mainly mercury cell, diaphragm cell, and the membrane cell.
