Concrete Retarder 98% Solid Content Sodium Gluconate As Construction Admixture
Sodium gluconate is a white crystalline powder that is easily soluble in water, slightly soluble in alcohol, and insoluble in ether. It is non-toxic and non corrosive.The production process of sodium gluconate mainly uses glucose as raw material and is prepared through chemical synthesis or biological fermentation.
Among them, biological fermentation is widely used due to its environmental friendliness and high efficiency.As a sodium carboxylate salt of glucose, it combines chelating and corrosion inhibition properties, and its natural origin and environmental attributes make it highly favored in the field of green chemistry. It is an ideal choice to replacemn traditional chemical additives and is widely used in multiple fields.

1.Used as a steel surface cleaning agent: When the steel surface needs to be plated with chrome, tin or nickel to adapt to special
purposes, such as making tinplate, galvanized sheet, chrome plating (electroplating), etc., the surface of the steel billet must be
strictly cleaned to make the coating firmly bonded to the steel surface. At this time, adding sodium gluconate to the cleaning agent
will achieve a very ideal effect.
2.Used in medicine: to regulate the acid-base balance in the human body to restore normal nerve function. It can also be used as a
food additive for the same purpose.
3.Concrete retarder and water reducer: After adding a certain amount of sodium gluconate to cement, the plasticity and strength of
concrete can be increased, and it has a blocking effect, that is, delaying the initial and final solidification period of concrete.
Therefore, sodium gluconate has been widely used in important construction projects abroad as a cement admixture, such as a
large number of bridge construction projects in the Middle East. In addition, it can also be used in electroplating and film
manufacturing industries.
4.Used as a water stabilizer: Sodium gluconate is widely used as a water stabilizer because of its excellent corrosion and scale
inhibition effects.
