It is non-corrosive, non-toxic and easily biodegradable (up to 98% after 2 days). As a chelating agent, it has attracted more and more attention.
The outstanding characteristic of sodium gluconate is its excellent chelating ability, especially in alkaline and concentrated alkaline solutions. It forms stable chelates with calcium, iron, copper, aluminum and other heavy metals. In this regard, it exceeds all other chelating agents, such as EDTA, NTA and related compounds.
Sodium gluconate aqueous solution is resistant to oxidation and reduction even at high temperature. It is easily biodegradable (the degradation rate is 98% after 2 days) and has no wastewater problem.
It is a good plasticizer and water reducer for concrete, mortar and gypsum.
Last but not least, it has the characteristic of inhibiting bitterness in food.
Sodium gluconate can combine well with calcium and other divalent and trivalent metal ions to form chelates, which can prevent scaling. It is suitable for removing calcium deposits on metal 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 polyamide fabrics.
In industry
Sodium gluconate is widely used in industry. can be used as high-efficiency chelating agent, steel surface cleaning agent, glass bottle cleaning agent, aluminum oxide coloring in electroplating industry, high-efficiency retarder and high-efficiency water reducer in construction, textile printing and dyeing, metal surface treatment and water treatment industries
Sodium gluconate is non-toxic. it in water and its chelate with heavy metal ions can be rapidly 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
Application of sodium gluconate in concrete engineering used as water reducing agent and retarder. 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 prolong the initial setting time from a few hours to a few days without damaging the strength. It can be used in pumping concrete, large fluidity concrete, mass concrete and high-strength performance concrete.
Suzhou Shicheng Chemical Co., Ltd. produces and sells more than 20 kinds of products such as industrial grade sodium gluconate, liquid sodium gluconate and calcium formate, which are widely used in textile printing and dyeing wastewater treatment, construction cement admixture, concrete admixture and other industries
