Seven uses of sodium gluconate

Sodium gluconate is widely used in industry and food industry. It is mainly used as food additive, high-efficiency chelating agent, steel surface cleaning agent, glass bottle cleaning agent, electroplating industrial aluminum oxide 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 the 1 quality concrete. In the construction of bridges in the Middle East, a large amount of sodium gluconate is used.

Large blocks and heavy weight of the perfusion project is more difficult to construct. Due to the addition of sodium gluconate, the improvement of concrete workability and the delay of setting time can avoid the generation of interface on the structure, and the result can improve the structural strength.

The addition of sodium gluconate to the concrete mixture can delay the setting time, which is very important for long-term and difficult perfusion. Oil well irrigation mud temperature is high, the operation is difficult. After adding sodium gluconate, the concrete can work at 170 ℃ for several hours.

Sodium gluconate is a new type of functional flavoring in the food industry. It can give food sour taste, prevent protein denaturation, can replace salt to produce low sodium, no sodium food. The salt taste of sodium gluconate is close to table salt, and its threshold is 5 times of table salt, 2.6 times of sodium malate and 16.3 times of sodium lactate, which is an excellent organic acid sodium salt.

Sodium gluconate as a corrosion inhibitor, its inhibition rate increases with the increase of temperature, while most of the other corrosion inhibitors decrease or fail with the increase of temperature. For the corrosion inhibition of carbon steel and other materials, the corrosion inhibition rate increases by more than 5% when the temperature grows from 21 ℃ to 49 ℃.

Sodium gluconate as a scale inhibitor, its scale inhibition ability is very strong, because it has a strong complexing ability for Ca, Mg, Fe, etc., especially for iron ions have excellent combining ability, almost in the whole PH range.

Sodium gluconate has a broad spectrum and coordination effect. It is not only suitable for molybdenum series formulations, but also for silicon, phosphorus, boron, tungsten, nitrite and other formulations and organic carboxylic acid formulations.

Sodium gluconate in the electroplating industry, as an electroplating additive, can be operated at a higher temperature, and can be directly plated gold bright coating, no longer need to go through polishing chrome plating, rust removal performance is good.

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 and exerting normal neuromuscular function, which can effectively prevent the occurrence of low sodium syndrome.
