SODA ASH DENSE
HS CODE 28362010
Glass manufacturing is by far the most important use for soda ash: more than 50% of the world’s soda ash production is indeed used to manufacture various types of glass :
Flat glass for the building (housing, high rise buildings) and automotive industries; Container or packaging glass for the preservation of beverages, food, pharmaceuticals, cosmetics and
Other commodity items;
Fiberglass for insulation or for reinforcement; Other glass products such as light bulbs, tableware and decorative glass blocks. Soda ash allows sand to melt at lower temperatures and therefore saving precious energy and prolonging glass furnace life.
Soda ash can be also used to purify and soften water, adjusting pH levels to make water less corrosive and thereby limiting pipe scaling. It reduces calcium or magnesium hardness and helps remove contaminants from water.
Soda ash (sodium carbonate) can be used to neutralize acidity in order to adjust the pH in swimming pools.
Soda ash can be used to treat toxic or refractory wastewaters, where it neutralizes acid waste streams. It can be used by automotive battery makers for treatment of sulfuric acid stream, and for final pH adjustment in effluent outflows.
Soda Ash (sodium carbonate) is used in a large number of chemical reactions. Many organic or inorganic substances can, when they combine with one or more sodium atoms, be made soluble or more soluble in water in a very economical way.
In this way Soda Ash is acting as a major raw material for the production of sodium bicarbonate (NaHCO3), sodium silicates (Na2O x SiO2), sodium tripolyphosphates (Na5P3O10), sodium orthophosphate (NaH2PO4-Na2HPO4 - Na3PO4), sodium metaphosphate (NaPO3), sodium percarbonate (2NaCO33H2O2), sodium dichromate (Na2Cr2O72H2O), sodium sulphite (Na2SO3), sodium metabisulphite (Na2S2O5) and many others.
Soda Ash is also used as raw material in fertilizers, coloring, enameling, pertroleum and fats, glues, gelatin industries
Sodium silicates are used for their detergent properties (in silicated soaps, in fabric washing powders, for dishwashers, for cleaning metals,…) and their binding properties (in cardboard and paper making, production of refractory and insulating materials, for ground consolidation, for fire protection,…).
Other applications of Sodium silicates are ink removal from waste paper, water treatment, ore flotation, production of special cements and zeolites.
Main applications of sodium phosphates are Detergents (removal and prevention of re-deposition of dirt) , Pharmaceutical industry and human and animal feed.
Sodium dichromate is used in the pigment industry, metal protection, leather and textile industries, organic syntheses, timber protection and manufacture of chromium derivatives.
Sodium sulphite is mostly used in waste water treatment in metal plating and tanning, product bleaching, preservation of certain foods and as introduction agent of the SO3 group into organic molecules (ex : production of acrylic fibers).
Sodium carbonate is used in the production of high performance powder detergents for laundry and dish washing.
Sodium carbonate is a very efficient source of alkalinity reserve and plays an important role in water softening. As a result it has been approved by many detergent producers in nil-phosphate containing formulations.
It may also be used for the direct soaking of clothes, dishwashing, floor washing and for degreasing operations.
For these applications, a large number of formulated domestic products, soaps, scouring powders, soaking and washing powders etc. contain a varying content of sodium carb
