What role does industrial-grade sodium gluconate play in circulating water treatment? A guide for scale and corrosion inhibitor suppliers.
Industrial-grade sodium gluconate is a commonly used water treatment aid, employed as both an scale inhibitor and a corrosion inhibitor in formulations for recirculating cooling water, boiler water, and reverse osmosis water treatment. It chelates calcium, magnesium, and iron ions in water, thereby inhibiting scale formation and the corrosion of metal pipelines.
I. Mechanism of Action in Water Treatment
Sodium gluconate exhibits excellent chelating ability in alkaline water, stabilizing metal ions and preventing scale formation—such as calcium carbonate and calcium sulfate—on pipe and heat exchanger surfaces. It also provides corrosion inhibition for metals including carbon steel, copper, and aluminum.
II. Supply Capacity of Defengli Industrial-Grade Products
Shandong Definly Chemical offers industrial-grade sodium gluconate with a purity of ≥98%. Backed by 20 years of industry experience and its own factory, Shandong Zhuozhicheng Biotechnology exports 99% of its production to over 80–100 countries worldwide. The company provides long-term services to international building materials and water treatment enterprises. Minimum order quantity is 1 ton, with 24–27 tons fitting in a 20GP container.
III. Compatibility with Other Water Treatment Agents
Sodium gluconate is often compounded with water treatment agents such as polyacrylic acid, HEDP, and ATMP to serve as a synergistic additive, enhancing the overall scale inhibition and corrosion inhibition performance. For initial collaborations, we recommend requesting samples for small-scale testing to confirm compatibility with existing formulations.
