Uncover the secrets of sodium gluconate。What is sodium gluconate?What fields is it widely used in? What is its role in other fields?
Sodium gluconate is composed of many hydroxyl groups and is called sodium pentahydroxylate. Molecular formula: C6H11O7Na, molecular weight: 218.14. The appearance is white or brown-yellow crystalline powder or granules. It is easily soluble in water and only needs to be slowly solidified. It is widely used in construction, washing, food, medicine and other industries. With the strengthening of national construction and the improvement of quality, the washing industry has made new developments. The market demand is very rapid and the market potential is huge.
Sodium gluconate is used for:
Cement chelate:
Add a certain amount of sodium gluconate to the cement, and then make the concrete firm and random. The first and last time can be delayed to ensure robustness.
Pharmaceutical industry:
Regulate the body’s acid-base balance and restore normal nerves. The same purpose applies to food additives
Steel surface cleaner:
Before electroplating Bo, Cr, Sn and Ni, the steel surface must be cleaned strictly. Now, sodium gluconate plays a very important role.
Special cleaning agent for glass bottles:
The main ingredient is sodium gluconate, this cleaning agent can improve these problems: it can not directly remove dirt. Blocking of nozzles and pipes. The food safety of the residue after washing is not ideal, and the water after washing causes pollution.
Sodium gluconate is a white to brown, granular to fine crystalline powder, which is easily soluble in water. It is non-corrosive, non-toxic, and easily biodegradable (up to 98% after 2 days), and it has attracted more and more attention as a chelating agent.
The outstanding feature of sodium gluconate is its excellent chelating ability, especially in alkaline and concentrated alkaline solutions. It forms stable chelates with calcium, iron, copper, aluminum and other heavy metals. In this respect, it surpasses all other chelating agents such as EDTA, NTA and related compounds.
The sodium gluconate aqueous solution is resistant to oxidation and reduction even at high temperatures. It is easily biodegradable (98% degradation rate after 2 days), and there is no waste water problem.
It is a good plasticizer and water reducer for concrete, mortar and gypsum.
Last but not least, it has the property of suppressing bitterness in foods.
Sodium gluconate can combine well with calcium and other divalent and trivalent metal ions to form a chelate, which can prevent scaling. It is suitable for removing calcium deposits on metals or other surfaces, including milk or beer scale on tinplate or stainless steel. Chelating properties are widely used in the textile industry to prevent iron deposition and desizing polyester and polyamide fabrics.
It can be used for alkaline rust removal, wall cleaning and metal carbonate deposition in metallurgy without causing corrosion. It can also be used as a cement admixture to control the setting time, improve the strength and water resistance of cement, and contribute to the frost resistance and crack resistance of concrete. Household cleaners, such as mouthwash.
Adding 4% sodium gluconate to feed can reduce weight gain and improve feed utilization. Adding phosphorus and zinc to feed can increase the rejection rate. Diets with and without phytase added increased magnesium retention and phosphorus content in tibia ash. A diet containing 2% sodium gluconate without phytase will also increase calcium retention.
