Product introduction

Sodium bicarbonate, with the molecular formula of NAHCO, is an inorganic compound, white crystalline powder, odorless, alkaline, and soluble in water. It decomposes slowly in humid air or hot air, producing carbon oxide, and completely decomposes when heated to 270 ° C. In case of acid, it will decompose strongly and produce carbon dioxide.

Industrial use

Sodium bicarbonate can be used to produce acid alkali fire extinguishers and foam fire extinguishers. In the rubber industry, sodium bicarbonate can be used to produce 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 assistant for cast steel (foundry) sand mold. In the printing and dyeing industry, sodium bicarbonate can be used as a fixing agent for dyeing and printing, an acid-base buffer, and a post-treatment agent for fabric dyeing and finishing; The addition of baking soda in dyeing can prevent the yarn from producing colored flowers, and can also be used as a detergent for wool.

Food processing purposes

In food processing, sodium bicarbonate is one of the most widely used loosening agents. It is used to produce biscuits, bread, etc., but it will remain sodium carbonate after action. Too much use will cause the alkalinity of food to be too large, resulting in the deterioration of flavor and yellowish-brown color. It is the generator of carbon dioxide in soda drinks; It can be compounded with alum to form alkaline fermentation powder, and can also be compounded with soda ash to form civil stone alkali; It can also be used as a butter preservative. It can be used as a color protection agent for fruits and vegetables 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, the PH value of fruit and vegetable can be increased, the water holding capacity of protein 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 milk, and the dosage is 0.001%~0.002%.

Agricultural and animal husbandry purposes

Sodium bicarbonate can be used for agricultural seed soaking, and can also make up for the deficiency of lysine content in feed. Dissolving sodium bicarbonate in a small amount of water or mixing it into concentrate to feed cattle (adding it appropriately) can promote the growth of cattle, and can also significantly improve the milk yield of cows.

Medical use

Sodium bicarbonate can be used as a raw material for pharmaceuticals to treat hyperacidity and metabolic acidosis, and also to alkalize urine to prevent uric acid kidney stones. It can also reduce the nephrotoxicity of sulfa drugs, prevent hemoglobin deposition in renal tubules during acute hemolysis, and treat the symptoms caused by excessive gastric acid; Intravenous drip has a non-specific therapeutic effect on barbiturate salicylic acid and methanol poisoning.

matters needing attention

Sodium bicarbonate is a non-hazardous material, but it should be protected from moisture. Store in dry and ventilated warehouse. It cannot be stored and transported with acids. When eating baking soda, it must not be stored and transported with toxic substances to prevent pollution.
