Product Description
Products Description
Sodium sulfite is commonly known as sulfur oxide powder, there are two kinds of sodium sulfite and sodium sulfite heptahydrate. Anhydrous sodium sulfite is white powder; Sodium sulfite heptahydrate is colorless or slightly yellow crystal, easily soluble in water, the aqueous solution is alkaline, easy to weather in the air and be oxidized to sodium sulfate. Sodium sulfite is widely used in industrial and civil fields. It is one of the important pulping methods in the paper industry to cook plant fiber with sodium sulfite cooking solution at a certain temperature and pressure, and the paper industry is also the industry that consumes the most sodium sulfite products. Sodium sulfite is widely used to remove dissolved oxygen from water because of its low price, convenient source and fast reaction rate with oxygen. Sodium sulfite is used for leather treatment, can make leather soft, full, tough, waterproof, anti-folding, wear and other properties. Sodium sulfite is a widely used food additive permitted by the state, which can be used as bleach, preservative, loose agent, antioxidant, color protection and fresh-keeping agent for food processing. Sodium sulfite is an inhibitor of polyphenol oxidase (PPO) activity, which can effectively protect the Browning of fruits and vegetables.

Application

Application field

Applications Edit Broadcast Laboratory use Sodium bicarbonate can be used as an analytical reagent, but also used in inorganic synthesis. Can be used to prepare sodium bicarbonate-sodium bicarbonate buffer solution, adding a small amount of acid or base can keep the hydrogen ion concentration does not change significantly, and can keep the pH value of the system relatively stable. Industrial use sodium bicarbonate can be used in the production of acid-base fire extinguishers and foam fire extinguishers, and in the rubber industry sodium bicarbonate can be used in the production of rubber and sponge. Sodium bicarbonate can be used as a flux for casting ingot in metallurgical industry. In the machinery industry, sodium bicarbonate can be used as a molding aid for casting steel (foundry) sand. In printing and dyeing industry, sodium bicarbonate can be used as fixing agent for dyeing and printing, acid-alkali buffer, and rear treatment agent for fabric dyeing and finishing. The addition of baking soda to dyeing can prevent the yarn from producing colored flowers, and can also be used as a detergent for wool. Food processing In food processing, sodium bicarbonate is one of the most widely used loose agents, used in the production of biscuits, bread, etc., but after the action will remain sodium carbonate, excessive use will make the food alkalinity is too large, resulting in bad flavor, yellow brown color. It is the producer of carbon dioxide in soft drinks; It can be combined with alum to form alkaline baking powder, and can also be combined with soda ash to form civil stone alkali. It can also be used as a butter preservative. In vegetable processing can be used as fruit and vegetable color protection agent. Adding about 0.1% to 0.2% sodium bicarbonate when washing fruits and vegetables can make the green stability. When sodium bicarbonate is used as fruit and vegetable treatment agent, the pH value of fruit and vegetable can be increased, the water retention of protein can be improved, the tissue cells of food can be softened, and the astringent components can be dissolved. In addition, it has the effect of removing the smell of sheep milk, and the use amount is 0.001% to 0.002%. Agricultural and animal husbandry use sodium bicarbonate can be used for agricultural seed soaking, but also can make up for the lack of lysine content in feed, sodium bicarbonate dissolved in a small amount of water or mixed into concentrate to feed cattle (add appropriate amount), can promote the growth of cattle, but also significantly improve the milk yield of cows. Medical use Sodium bicarbonate can be used as a pharmaceutical raw material to treat excess stomach acid, metabolic acidosis, and to alkalize urine to prevent uric acid kidney stones. It can also reduce the renal toxicity of sulfonamides, prevent hemoglobin deposition in renal tubules during acute hemolysis, and treat the symptoms caused by excessive stomach acid; Intravenous infusion has non-specific therapeutic effect on barbiturates, salicylic acids and methanol poisoning. However, it is prohibited for gastric lavage when swallowing strong acid poisoning, and a large number of injections, renal insufficiency or long-term application can cause arrhythmia, muscle spasm, pain, abnormal fatigue and weakness, slow breathing, oral odor, frequent urination, urgent urination, persistent headache, loss of appetite, nausea, vomiting, etc.
