Soda Ash Light

Soda ash commonly called as washing soda and it’s a sodium salt of carbonic acid. Soda ash is an economic importance chemical because of its applications in manufacturing glass, chemicals, paper, detergents and many other industries. Sodium carbonate commonly occurs in nature in three different forms of hydrates such as sodium carbonate decahydrate (Natron), sodium carbonate heptahydrate and sodium carbonate monohydrate (thermonatrite).

Textile and Leather

To enhance the pH (alkalinity) of the reaction, soda ash Light is used in dyeing cotton and other cellulose fibres such as linen, rayon, tencel, or hemp. The optimal pH varies depending on the fiber and dye color. Soda ash alters the pH of the fibre-reactive dye and the cellulose fibre, causing the dye to react with the fibre and form a permanent bond with it.

Soap and Detergent

Soda ash prevents hard water from combining with detergent, allowing for more even cleaning agent distribution during the wash cycle. Soda ash can also be used to remove stains from garments caused by alcohol and grease.

In detergents, medium density or lighter grades of soda ash are typically employed. The products work as a builder in soap, detergent, and other cleaning chemical formulas, preparing wash water to obtain the best level of soil removal. Soda ash provides additional benefits by assisting agglomeration, acting as a surfactant carrier, and serving as an alkali source for pH correction. Soda ash is found in a variety of formulated household items, such as soaps, scouring powders, soaking and washing powders, and so on.

Chemical Raw Materials

Soda ash has long been recognized as a source of sodium ions. Many inorganic chemicals’ solubility and reactivity in water are also aided by it. As a result, it is a key raw material in the synthesis of sodium phosphates, sodium silicates, chrome compounds, and photographic chemicals at a low cost. It’s also used to make sodium bicarbonate (baking soda), a key chemical in the beverage, coatings, detergents, food, dialysis, and personal care industries.

Manufacturing Process

soda ash light manufacturing process

The main reaction of the manufacturing process is the reaction of salt, ammonia and carbon dioxide  to form a dense ash and intermediate ammonium chloride. Dense ash is separated by sedimentation. Slaked lime is used to degrade ammonium chloride from the mother liquor. The recovered ammonia is recycled, and inventory is only needed to compensate for the loss. The dense ash is heated in a kiln, and soda ash is generated from carbon dioxide and recycled as in reaction.
