China High quality food/tech grade sodium gluconate
Sodium gluconate is the sodium salt of gluconic acid. It is white or pale yellow crystalline granules or powder, quite easily soluble in water, slightly soluble in alcohol, insoluble in ether. Sodium gluconate is retardation water-reducing agent, powder and low-air-entraining, and it is a kind of nature anionic surfactant of high molecular polymer.
Main performance
1. Sodium gluconate can be used as water quality stabilizer because it has excellent inhibiting capacity to scale.
2. Sodium gluconate is used as surface cleaning agent of metal and glass.
3. Sodium gluconate can be used as water reducing, setting retarder of concrete.
