Industrial use
Sodium bicarbonate can be used in the production of acid-base fire extinguishers and foam fire extinguishers. In the rubber industry, sodium bicarbonate can be used in the production of rubber and sponge. In the metallurgical industry, sodium bicarbonate can be used as a flux for casting steel ingots. In the mechanical industry, sodium bicarbonate can be used as a molding aid for cast steel (sanding) sand mold. In the printing and dyeing industry, sodium bicarbonate can be used as a fixative for dyeing and printing, an acid-base buffer, and a post-treatment agent for fabric dyeing and finishing; Baking soda added in dyeing can prevent the yarn from producing colored flowers, and can also be used as a detergent for wool.
Food processing applications
In food processing, sodium bicarbonate is one of the most widely used loosening agents, which is used in the production of biscuits, bread, etc., but sodium carbonate will remain after the action. Excessive use will make the food too alkaline and lead to poor flavor and yellowish brown color. It is the generating agent of carbon dioxide in soft drinks; It can be compounded with alum into alkaline fermentation powder, and it can also be compounded with soda ash into civil alkaloid; It can also be used as butter preservative. It can be used as color fixative in vegetable processing. When washing fruits and vegetables, adding about 0.1% - 0.2% sodium bicarbonate can make the green stable. When sodium bicarbonate is used as a fruit and vegetable treatment agent, by boiling and bleaching fruits and vegetables, the pH value of fruits and vegetables can be increased, the water holding capacity of proteins can be improved, the softening of food tissue cells can be promoted, and the astringent ingredients can be dissolved. In addition, it can remove the smell of mutton in goat milk, and the dosage is 0.001% - 0.002%.
Agricultural and animal husbandry use
Sodium bicarbonate can be used for soaking seeds in agriculture, and can also make up for the lack of lysine content in feed. Dissolving sodium bicarbonate in a small amount of water or mixing it into concentrate to feed cows (adding it appropriately) can promote the growth of cows and significantly improve the milk production of cows.
Medical use
Sodium bicarbonate can be used as the raw material of medicine to treat gastric hyperacidity and metabolic acidosis. It can also alkalize urine to prevent urinary acid kidney stones. It can also reduce the nephrotoxicity of sulfa drugs, prevent hemoglobin from depositing in renal tubules during acute hemolysis, and treat symptoms caused by excessive gastric acid; Intravenous drip has a nonspecific therapeutic effect on barbiturates, salicylates and methanol poisoning. However, it is forbidden to use it for gastric lavage when swallowing strong acidosis, and when a large amount of injection, renal insufficiency or long-term application, arrhythmia, muscle spasm, pain, abnormal fatigue and weakness, slow breathing, peculiar smell in the mouth, frequent urination, urgency of urination, persistent headache, anorexia, nausea, vomiting, etc. may occur
