Application:

1. Construction & Infrastructure

Concrete Additive: Acts as a high-efficiency retarder and water reducer, precisely controlling concrete setting time (extending workability by 4–12 hours) while enhancing compressive strength by 10–20%. Ideal for mass concrete pouring, long-distance transportation, and large-scale projects like high-rises, bridges, and tunnels.

Cement Precast Components: Improves mold filling performance and surface finish of precast parts (pipes, slabs, building components), reducing demolding time and ensuring consistent quality.

Self-Leveling Floors: Enhances slurry fluidity and leveling property, forming smooth, dense, and wear-resistant floor surfaces for industrial workshops, commercial spaces, and civil buildings.

Transportation & Hydraulic Engineering: Used in highway/railway subgrades, bridge decks, and water conservancy projects (dams, canals), improving concrete impermeability, freeze-thaw resistance, and corrosion resistance in harsh environments.

2. Metal Surface Treatment & Cleaning

Metal Cleaner: Serves as a chelating agent in steel surface cleaning, effectively removing rust, oil stains, and oxide layers without corroding the substrate. Suitable for automotive parts, hardware, and mechanical component processing.

Electroplating Industry: Assists in aluminum oxidation coloring and electroplating bath formulation, stabilizing the plating solution, improving coating uniformity and adhesion, and enhancing the brightness of finished products.

Glass Bottle Cleaning: Used in food/beverage glass bottle washing, efficiently chelating metal ions in water to avoid water spots and ensure thorough cleaning, complying with food safety standards.

3. Water Treatment & Textile

Water Treatment Agent: Chelates calcium, magnesium, iron, and other heavy metal ions in industrial circulating water and wastewater, preventing scale formation in pipelines and equipment, and improving water treatment efficiency.

Textile Dyeing: Acts as a chelating and leveling agent in textile printing and dyeing, eliminating the impact of metal ions on dyes, ensuring uniform coloration, and enhancing color fastness.

4. Other Industrial Fields

Oilfield & Coal Mine: Used in drilling fluid formulations as a stabilizer and corrosion inhibitor, reducing formation damage and protecting drilling equipment in harsh downhole environments.

Food & Pharmaceutical: Food-grade sodium gluconate serves as a stabilizer, flavor regulator, and chelating agent in food processing (beverages, dairy, baked goods). In pharmaceuticals, it’s used as an excipient for drug formulations.

Daily Chemicals: Added to detergents, soaps, and personal care products (shampoos, lotions) as a chelating agent and pH regulator, improving product stability and mildness.

Packing: 25kg/bag or customized as customer’s request

Storage: Stored  in a cool, dry, well-ventilated area with tight sealing, away from sunlight, high temperature, humidity, strong oxidants, acids, alkalis and toxic substances, and avoid violent handling.
