What Industries Can Sodium Gluconate Be Used In?

What is sodium gluconate?

Sodium gluconate, also known as sodium pentahydroxy organic acid, is a white crystalline particle or powder with a relative molecular mass of 218.14 and a melting point of about 206 ℃. 10% aqueous solution pH 6.2~7.8, easily soluble in water, slightly soluble in alcohol, insoluble in ether, and has a certain salty taste. It is widely used in food, construction, medicine, water treatment, electroplating, development, and other industries, especially in the food industry. With the continuous improvement of people's living standards and health care consciousness, the requirements for food nutrition and flavor are getting higher and higher, and the food industry is developing towards the road of health with a diversified diet, green food, and low.

Applications of sodium gluconate

Used in medicine

As one of the essential fine chemical products, sodium plays an important role in maintaining extracellular osmotic pressure and volume, regulating acid-base balance, and performing normal function of neuromuscular, and can effectively prevent the occurrence of hyponatremia syndrome.


With excellent corrosion and scale inhibition, it is widely used as a water quality stabilizer. With obvious coordination effect, suitable for various formulations of molybdenum, silicon, phosphorus, tungsten, nitrite, etc.; corrosion inhibition rate increases with temperature; strong scale inhibition ability, strong complexation ability for calcium, magnesium and iron salts; as circulating and cooling water corrosion and scale inhibition agent to achieve extinction of public hazards.

Used as steel surface cleaning agent

If the steel surface needs platinum plating, chromium plating, tin plating, nickel plating to adapt to special purposes, the surface of its billets need to be strictly cleaned, so that the plating material and steel surface firmly combined, the addition of sodium gluconate in the cleaning agent will achieve very satisfactory results. 4. as a special cleaning agent for glass bottles with sodium hepta gluconate as the main formula of the glass bottle professional cleaning agent can improve the scaling force is not strong, easy to block the nozzle of the bottle washing machine and It is not ideal for bottle stickers and bottle neck rust; the trace residue after washing is not ideal for food safety (such as phosphate residue); the discharge of washing water becomes a public hazard (not in line with the national standards).

Construction industry

As water reducing agent and retarder: When a certain amount of sodium gluconate is added to cement, it can increase the plasticity and strength of concrete, and has a retarding effect, i.e., delaying the initial and final setting time of concrete. It can also be used in many industrial fields such as electroplating, film manufacturing, etc. The application prospect is very broad.
