The product absorbs moisture from the air and dissolves in it. It has a minimum concentration of 98% sodium hydroxide by weight, according to specification. At the Cubatão plant, it is manufactured in scales and at the Bahía Blanca plant, in Argentina, it is manufactured in pearls. The product is sold in 25 kg polyethylene bags (in Brazil and Argentina) palletized – and in Argentina sold in big bags. It is used in several industries, such as food, pulp and paper, water treatment and detergents. It is also used in household cleaning products.
Manufacturing of the soda pearls is quite similar to the evaporation process of liquid caustic soda, except in the final stage, where, instead of scales, the melted soda is screened on a plate with multiple perforations, thus forming small liquid spheres that flow into the tower by gravity. While falling, the drops are crystalized by cooling, in their flow against the ambient air, thus forming the pearls.
It is used to make soap and detergents, in ferrous metal surface treatment, in the development of electrodeposition baths, to mercerize textiles, to regeneration ion-exchange resins, and to adjust the pH in several industrial processes, such as those in the food, alcohol and pharmaceutical industries.
