Why Choose Our Sodium Gluconate Powder?Multi-Industry Versatility

One raw material serves three major industries: construction admixtures, industrial cleaning, and food/pharmaceutical ingredients, helping customers expand product portfolios and reduce sourcing complexity.

Sodium Gluconate EverStar Group

Precise Concrete Retarding Performance

Our sodium gluconate provides stable and predictable setting-time control. At a dosage of 0.05%–0.15% of cement weight, it can consistently delay setting by 2–7 hours under normal conditions. Unlike citric acid or sucrose, which may cause flash setting at very low dosages, sodium gluconate offers a linear relationship between dosage and retardation time, helping prevent cold joints during concrete pouring.

Superior Chelating Efficiency

In strongly alkaline environments (pH > 11), sodium gluconate demonstrates stronger ferric ion chelation performance than EDTA. It is highly biodegradable, achieving over 90% degradation within 28 days, making it an environmentally compliant solution.

Outstanding Cost Performance

Compared with conventional chelating agents, sodium gluconate can reduce procurement costs by 20%–40% while delivering comparable performance. Direct factory supply ensures stable quality and competitive pricing.

Core Applications Across Industries

Building & Ready-Mixed Concrete

Ideal for hot-weather construction and long-distance concrete transportation.
Extends concrete workability and slump retention.
Helps prevent cold joints in large-volume structures.
Recommended dosage: 0.03%–0.08% under normal conditions, up to 0.15% in summer.

Industrial Cleaning & Metal Surface Treatment

Removes rust and oxide scale before electroplating.
Avoids hydrogen embrittlement associated with acid pickling.
Used in glass bottle washing systems to chelate calcium and magnesium ions, preventing nozzle blockage.

Circulating Water Treatment

Provides both scale inhibition and corrosion protection.
Maintains excellent stability under fluctuating pH conditions.
Outperforms traditional polyphosphate-based treatments.

Textile Printing & Dyeing

Stabilizes copper and iron ions during hydrogen peroxide bleaching.
Prevents abnormal peroxide decomposition and protects fabric fibers.

Quality Assurance You Can Trust

Rigorous Testing Protocols

Every production batch undergoes comprehensive laboratory verification. We test purity via HPLC and titration methods, ensuring consistent results batch after batch. Reducing substances remain controlled below 0.5%, indicating complete fermentation without residual sugars that could cause bacterial growth or color instability.

Strict Impurity Controls

Chloride and sulfate levels stay well below 0.05% to prevent rebar corrosion in reinforced concrete Applications. Heavy metal content (Pb, As) maintains strict limits under 2 ppm for REACH and FDA compliance.

Optimized Physical Properties

Particle size consistency (typically 20-60 mesh) ensures rapid dissolution in automated dispensing equipment. Our moisture-proof packaging with PE liners prevents hygroscopic caking that disrupts your dosing systems.

EverStar Group Chemical Retarder Certificate

Storage & Handling Best Practices

Store in a cool, dry warehouse and keep the product in its original sealed packaging. Recommended storage conditions are a temperature below 30°C and relative humidity below 60%. As the product is slightly hygroscopic, prolonged exposure to moisture may cause caking and affect automated feeding systems. It is a non-corrosive, low-toxicity material; however, excessive dust generation should be avoided during handling to ensure safe and efficient operation.

FAQ

Q:What is the recommended dosage for concrete applications?

A: The recommended dosage is 0.03%–0.15% based on cement weight. The dosage should not exceed 0.25%. Higher temperatures generally require higher dosage levels. Trial batching is recommended before large-scale use.

Q:Can sodium gluconate be used with PCE polycarboxylate superplasticizers?

A: Yes. It offers excellent compatibility with PCE admixtures and can significantly improve concrete slump retention, especially under high-temperature conditions.

Q:Is the product sensitive to moisture?

A: It is slightly hygroscopic. Long-term exposure to high humidity may result in caking. Sealed storage in a dry environment is recommended.

Q:Should food-grade sodium gluconate be used for industrial cleaning?

A: Industrial-grade material is suitable for general industrial cleaning and civil engineering applications. Food-grade products are recommended for food-contact surfaces and food processing environments.

Q:Why choose sodium gluconate instead of EDTA in alkaline cleaning systems?

A: Under strong alkaline conditions (pH ≥ 11), sodium gluconate exhibits significantly better calcium, magnesium, and iron ion chelation performance than EDTA, whose effectiveness decreases substantially at high pH levels.

Q:Can customized formulations be provided?

A:Yes. We offer customized particle sizes, high-purity specifications, and special compound formulations. Customized solutions and samples can typically be prepared within 24 hours.
