Product Description

Product Description:
Sodium bicarbonate, commonly known as baking soda, has the molecular formula NaHCO3. It is an inorganic compound, a white powder or fine crystals with a salty taste. It is readily soluble in water, slightly soluble in ethanol, and its aqueous solution is slightly alkaline. It decomposes easily when heated, slowly in humid air, and begins to decompose rapidly at 50ºC, completely decomposing at 270ºC. It decomposes violently in the presence of acids, producing carbon dioxide. Sodium bicarbonate plays an important role in various industries, including chemical, pharmaceutical, food, light industry, and textiles, as well as in people's daily lives.

Application Description:
Laboratory Uses: Sodium bicarbonate can be used as an analytical reagent and in inorganic synthesis. It can be used to prepare sodium carbonate-sodium bicarbonate buffer solutions, maintaining a relatively stable pH level even with the addition of small amounts of acid or alkali, preventing significant changes in hydrogen ion concentration.

Industrial Uses: Sodium bicarbonate can be used in the production of acid-base fire extinguishers and foam fire extinguishers. In the rubber industry, it is used in the production of rubber and sponge. In the metallurgical industry, it is used as a flux in casting steel ingots. In the machinery industry, it is used as a molding aid in casting steel (sand casting) molds. In the printing and dyeing industry, it is used as a color-fixing agent in dyeing and printing, an acid-base buffer, and a post-treatment agent in fabric dyeing and finishing. Adding baking soda during dyeing can prevent color spots on yarn packages, and it can also be used as a detergent for wool.

Food Processing Uses: In food processing, sodium bicarbonate is one of the most widely used leavening agents, used in the production of biscuits, bread, etc. However, sodium carbonate residue remains after its action. Excessive use can lead to excessive alkalinity in food, resulting in poor flavor and a yellowish-brown color. Sodium bicarbonate is a carbon dioxide generator in carbonated beverages; it can be combined with alum to form alkaline baking powder, or with soda ash to form household soda ash; it can also be used as a butter preservative. In vegetable processing, it can be used as a color-protecting agent for fruits and vegetables. Adding approximately 0.1%~0.2% sodium bicarbonate when washing fruits and vegetables can stabilize their green color. When used as a fruit and vegetable treatment agent, boiling or rinsing fruits and vegetables can raise their pH value, improve the water-holding capacity of proteins, promote the softening of food tissue cells, and dissolve astringent components. Furthermore, it has a deodorizing effect on goat milk, with a usage of 0.001%~0.002%.

Agricultural and livestock uses: Sodium bicarbonate can be used for seed soaking in agriculture and can also compensate for the lack of lysine in feed. Dissolving sodium bicarbonate in a small amount of water or mixing it into concentrate feed for cattle (adding an appropriate amount) can promote cattle growth and significantly increase milk production in dairy cows.

Medical Uses:Sodium bicarbonate can be used as a raw material in pharmaceuticals to treat hyperacidity and metabolic acidosis. It can also alkalize urine to prevent uric acid kidney stones. It can reduce the nephrotoxicity of sulfonamides and prevent hemoglobin deposition in the renal tubules during acute hemolysis, treating symptoms caused by hyperacidity. Intravenous infusion has a non-specific therapeutic effect on poisoning by barbiturates, salicylates, and methanol. However, it is contraindicated for gastric lavage in cases of strong acid poisoning. Large injections, renal insufficiency, or long-term use may cause arrhythmias, muscle spasms, pain, abnormal fatigue and weakness, slowed breathing, bad breath, urinary frequency, urgency, persistent headache, loss of appetite, nausea, and vomiting.

Our Processes:
In terms of production processes, the mainstream sodium bicarbonate production methods in China include the natural alkali method, the synthetic method (soda ash carbonation method), and the metathesis method. The natural alkali method uses readily available raw materials and has lower costs, but the product has a relatively high chloride content, and production is limited to natural alkali mining areas. The synthetic method is usually integrated with soda ash plants, producing high-purity products with fewer impurities, but it consumes more energy and is greatly affected by raw material prices. The metathesis method uses sodium chloride and ammonium bicarbonate as raw materials. Our company's production process involves multiple stages, including alkali formation, clarification, carbonation, separation, and drying.
