1. In building industry: As retarder and water reducing agent. Adding sodium gluconate in cement can increase plasticity and strength while delaying solidification time.
2. Surface cleaning for steel: Ensures coatings bond firmly by strictly cleaning surfaces.
3. Special cleaning agent for glass: Ideal for bottle washing, preventing nozzle blockage and ensuring food safety residues are removed.
4. Water stabilizer: Functions as an excellent antiscale and inhibitor.
5. Industrial fields: Widely used in electroplating, film manufacturing, and more.
