It is non-corrosive, non-toxic and easily biodegradable (up to 98% after 2 days). As a chelating agent, sodium gluconate has attracted more and more attention.

The outstanding feature of sodium gluconate is its excellent chelating ability, especially in alkaline and concentrated alkaline solutions. It forms stable chelate with calcium, iron, copper, aluminum and other heavy metals. In this respect, it surpasses all other chelating agents such as EDTA, NTA and related compounds.

The sodium gluconate aqueous solution can resist oxidation and reduction even at high temperatures. Easily biodegradable (98% degradation rate after 2 days), there is no waste water problem.

It is a good plasticizer and water reducer for concrete, mortar and gypsum.

Last but not least, it has the property of suppressing the bitter taste of food.

Sodium gluconate can combine well with divalent and trivalent metal ions such as calcium to form a chelate to prevent scaling. It is suitable for removing calcium deposits on metals or other surfaces, including milk or beer scale on tinplate or stainless steel. The chelating properties of sodium gluconate are widely used in the textile industry to prevent iron deposition and desizing of polyester and nylon fabrics.

In industry

Sodium gluconate is widely used in industry. It can be used as a high-efficiency chelating agent, steel surface cleaning agent, glass bottle cleaning agent, aluminum oxide coloring in the electroplating industry, construction, textile printing and dyeing, metal surface treatment, and water high-efficiency retarder and superplasticizer treatment industries

Sodium gluconate is non-toxic. Its chelate complex with heavy metal ions in water can be quickly and completely degraded by ordinary biochemical treatment. The heavy metal ions released in the degradation process can be removed by precipitation or adsorbed on the sludge formed in the wastewater treatment process.

In concrete

The application of sodium gluconate as a water reducer and retarder in concrete engineering. Its water reducing, plasticizing and retarding effects are very significant. It can greatly improve the workability of concrete, reduce slump loss, and improve the later strength of concrete. As a retarder, it can extend the initial setting time from a few hours to a few days without destroying the strength. It can be used for pumping concrete, high-fluidity concrete, large-volume concrete and high-strength concrete.

Suzhou Shicheng Chemical Co., Ltd. produces and sells more than 20 products such as industrial grade sodium gluconate, liquid sodium gluconate, calcium formate, etc., which are widely used in textile printing and dyeing wastewater treatment, construction cement admixtures, concrete admixtures and other industries
