Applications of Sodium Gluconate! Can it Replace Sodium Salt

Sodium gluconate is widely used in the industrial and food industries. It is mainly used as food additives, high-efficiency chelating agents, steel surface cleaning agents, glass bottle cleaning agents, electroplating industrial aluminum oxygen coloring, high-efficiency retarder, high-efficiency water reducing agent, etc.


Sodium gluconate can prolong the setting time of concrete, reduce the slump of concrete and its loss over time, and improve the strength of concrete. Specific applications are as follows:
The use of sodium gluconate can reduce the water-cement ratio, thereby increasing the strength of concrete. This is a high quality concrete. Large amounts of sodium gluconate are used in bridge construction in the Middle East.
Large and heavy pouring projects are more difficult to construct. Due to the addition of sodium gluconate, the workability of concrete is improved and the setting time is delayed, which can avoid the occurrence of contact surfaces on the structure, and as a result, the structural strength can be increased.
Adding sodium gluconate to the concrete mix can delay the setting time, which is important for long and difficult pouring.
The temperature of the oil well irrigation mud is high and the operation is difficult. After adding sodium gluconate, concrete can work at 170℃ for several hours.

Sodium gluconate is a new type of functional flavoring seasoning in the food industry. It can give food a sour taste, prevent protein denaturation, and can replace salt to prepare low-sodium and sodium-free foods.
The unique function of sodium gluconate and potassium gluconate when shared has greater advantages than other organic acids. It can complete sterilization of beverages at pH 4, sterilization temperature 65°C, and 10 minutes without affecting the taste. link.
The salt taste of sodium gluconate is close to that of table salt, and its threshold value is 5 times that of table salt, 2.6 times that of sodium malate, and 16.3 times that of sodium lactate. It is an excellent sodium salt of organic acids.

As a corrosion inhibitor, the corrosion inhibition rate of sodium gluconate increases as the temperature rises, while most other corrosion inhibitors decrease or fail as the temperature rises. For corrosion inhibition of carbon steel and other materials, when the temperature increases from 21°C to 49°C, the corrosion inhibition rate increases by more than 5%.

As a scale inhibitor, sodium gluconate has extremely strong anti-scaling ability because it has strong complexing ability for Ca, Mg, Fe, etc., especially for iron ions, almost in the entire pH range. It has an effect inside.

Sodium gluconate has broad spectrum and coordinated effects. It is not only suitable for molybdenum series formulas, but also for silicon, phosphorus, boron, tungsten, nitrite and other series formulas and organic carboxylic acid formulas.

Sodium gluconate is used as an electroplating additive in the electroplating industry. It can be operated at higher temperatures and can be directly plated with a bright gold coating without polishing and chrome plating. It has good rust removal performance.

Sodium gluconate can regulate the acid-base balance in the human body in the medical industry. Sodium plays an important role in maintaining extracellular osmotic pressure and capacity, exerting normal neuromuscular functions, and can effectively prevent the occurrence of hyponatremia syndrome.
