🚀 Product Application
Application Overview

Sodium Gluconate's excellent performance makes it play an important role in many fields such as medicine, construction, textile printing and dyeing, metal surface treatment and water treatment, and the concrete industry.

🏗️ Construction

Used as a cement additive with significant water reduction and retarding effects. Improves workability and extends construction time.

🧪 Chemical Industry

Basic raw material for gluconates. Used in electroplating as a brightener (0.1-0.2g/L) to clarify plating solutions.

💧 Water Treatment

Functions as a scale and corrosion inhibitor. Highly effective when combined with aluminum to extend equipment life.

🍴 Food & Pharma

Adjusts taste, acidity, and coagulation in food. In pharma, it adjusts acid-base balance and maintains osmotic pressure.
