Used as steel surface cleaning agent:
Steel surface for plating bowls, chrome plating, tin plating, nickel plating, to adapt to the special purpose, such as tin, galvanized sheet, chrome plated surface (electric), etc., the billet surface must pass strict cleaning, solid combination, make steel surface coating and then cleaning reagent adding sodium gluconate it will achieve the ideal effect.
Used as cement admixture:
After adding a certain amount of sodium gluconate into cement, the plasticity and strength of concrete can be increased, and it has a blocking effect
That is, to delay the initial and final solidification period of concrete, such as adding 0.15% sodium gluconate, can extend the initial solidification time of concrete more than 10 times, that is, to extend the plastic time of concrete from a few hours to a few days, without affecting its firmness. Plasticity and delay of initial setting time are very important problems in concrete operations. For example, in high-temperature construction and large-scale engineering operations, delay of initial setting time is a difficult problem, and sodium gluconate can solve this problem satisfactorily. Other high temperature cementing Wells is difficult, after adding the sodium gluconate concrete under 170 ℃ high temperature, the plastic within a few hours, so it can successfully solve the above problems. Therefore, sodium gluconate as cement admixture has been widely used in important construction projects abroad, such as a large number of bridge projects in the Middle East. But our domestic application in this area has not been promoted, it is said that there is in the papermaking wastewater extraction cellulose sulfonate sodium, its effect and sodium gluconate is simply not comparable.
In addition, it can also be used in electroplating, film manufacturing industry.
As a kind of polyhydroxy carboxylic acid type excellent corrosion and scale inhibitor sodium gluconate, due to the above special properties, if the application technology is willing to work hard, will be developed into a great industry.
