FAQ
Q1: What is the difference between food-grade and industrial-grade sodium gluconate?
A1: Food-grade meets strict food safety standards. Industrial-grade focuses on chelation and retarding performance for construction and water treatment, not for food processing.
Q2: Will sodium gluconate cake during storage?
A2: It may cake if exposed to humid air. Store in sealed dry warehouse to avoid this situation.
Q3: Is sodium gluconate dangerous to handle?
A3: It is low-risk. Rinse skin with clean water after contact. Avoid breathing powder dust.
Q4: What affects the retarding effect of sodium gluconate in concrete?
A4: Cement type, ambient temperature and adding dosage will influence its performance. Small pre-test is recommended before mass use.
Q5: Can sodium gluconate mix with other chemical additives?
A5: Most common combinations are available. Compatibility test is required before large batch mixing.
Main Applications
1. Concrete Retarder for Ready-mixed Concrete Sodium gluconate is widely used as retarder in ready-mixed concrete. It delays cement hydration reaction and extends setting time, which helps concrete transportation over long distances.
2. Chelating Agent for Industrial Circulating Water Treatment It can bind metal ions in circulating water, reduce scale formation and protect pipeline equipment. This improves the efficiency of water circulation systems.
3. Food Additive in Beverage and Bakery Products Food-grade sodium gluconate acts as acidity regulator and quality improver. It stabilizes the taste and texture of drinks and baked food.
4. Auxiliary Agent for Metal Surface Cleaning Added into industrial cleaning formulas, it removes scales and oxide layers without strong corrosion to metal surfaces.
5. Mild Chelator for Cosmetic Raw Materials It works as a gentle chelating ingredient in skincare formulations. It stabilizes the whole formula and extends shelf life of cosmetics.
Storage & Transportation ：Store in cool, dry and ventilated warehouse. Keep packages tightly sealed, away from moisture and strong oxidants. Shelf life: 24 months under original sealed package. It is non-dangerous goods for shipment. Prevent package damage and dampness during transport.
