Sodium bicarbonate, also known as baking soda or bicarbonate of soda, is an inorganic compound with the molecular formula NaHCO₃. Its appearance is white crystalline powder, odorless, salty, soluble in water. It decomposes slowly in humid air or hot air to produce carbon dioxide, and bicarbonate of soda will decompose completely when heated to 270 °C. If it encounters acid, sodium hydrogen carbonate will decompose strongly and produce carbon dioxide. What’s more, sodium bicarbonate powder is widely used in analytical chemistry, inorganic synthesis, industrial production, agricultural and animal husbandry production, etc.
What Is Sodium Bicarbonate Powder Used For?
Sodium bicarbonate powder is mainly applied as food additive in food stuff industry, feed additives for animals, foaming agent in rubber industry, acidifying agent in medicine industry, compounding ingredient in detergent making, detergent in movie making, carbon Dioxide (CO2) reactor in beer,drinks,etc.
It can be used to produce acid-base fire extinguishers and foam fire extinguishers.
In the rubber industry, sodium hydrogen carbonate can be used in the production of rubber and sponge. In the metallurgical industry, bicarbonate of soda can be used as a flux for casting steel ingots.
In the machinery industry, bicarbonate of soda can be used as a molding aid for cast steel (foundation) sand molds.
In the printing and dyeing industry, sodium bicarbonate can be used as a color-fixing agent for dyeing and printing, an acid-base buffering agent, and a post-treatment agent for fabric dyeing and finishing. Adding sodium bicarbonate powder in the dyeing can prevent the bobbin from producing colored flowers, and it can also be used as a detergent for wool.
