Sodium gluconate is a kind of organic matter, chemical formula C6H11NaO7, in the industry is very widely used, sodium gluconate can be used in construction, textile printing and dyeing and metal surface treatment and water treatment industries as efficient chelating agent, steel surface cleaning agent, glass bottle cleaning agent, electroplating industrial aluminum oxide coloring, in the concrete industry as a high efficiency retarding agent, high efficiency water reducing agent.

Used as a cleaning agent for steel surface:

Steel surface such as the need for plating bowl, chromium plating, tin plating, nickel plating to adapt to special uses, such as the manufacture of tinplate, galvanized plate, surface chromium plating (electrical), etc., the billet surface are strictly cleaned, so that the coating and steel surface firmly combined, at this time the cleaning agent to add sodium gluconate will achieve very ideal results. This has been confirmed by the major companies in the international manufacture of tinplate.

Used as cement admixture:

Adding a certain amount of sodium gluconate to cement can increase the plasticity and strength of concrete, and has blocking effect

That is, delaying the initial and final solidification period of concrete, such as adding 0.15% sodium gluconate, can extend the initial solidification time of concrete by more than 10 times, that is, extend the plastic time of concrete from a few hours to a few days, without affecting its stiffness. Plasticity and delay of initial setting time are very important problems in concrete work, such as in high temperature season construction and large-scale engineering work, delay of initial setting time is a difficult problem, sodium gluconate can solve this problem. In addition, it is difficult to glue oil Wells at high temperatures, and the concrete after adding sodium gluconate can be plastic in a few hours at a high temperature of 170℃, so the above problems can be successfully solved. Therefore, sodium gluconate as a cement admixture has been widely used in important construction projects abroad, such as a large number of bridge projects in the Middle East. However, our domestic application in this area has not yet been promoted, it is said that there is the extraction of cellulose sodium sulfonate in papermaking wastewater, and its effect is simply not comparable to sodium gluconate.

In addition, it can also be used in electroplating and film manufacturing industries.

As a kind of polyhydroxy-carboxylic acid excellent corrosion and scale inhibitor sodium gluconate, because of its many special properties, if it can work hard in the application technology, it will be developed into a large industry.
