　　1. For medicine, it can regulate the acid-base balance in the human body to restore the normal function of the nerve, and is used for food additives for the same purpose;

　　Used as a water quality stabilizer, its excellence is manifested in:

　　（1） It has obvious coordination effect and is suitable for various formulations such as molybdenum, silicon, phosphorus, tungsten and nitrite. The corrosion inhibition effect is greatly improved due to the coordination effect;

　　（2） contrary to general corrosion inhibitors, the corrosion inhibition rate increases with increasing temperature;

　　（3） The technical requirements for scale inhibition ability have strong complexing ability for calcium, magnesium and iron salts, especially for Fe3+.

　　2. Iron surface cleaning agent: If the steel surface needs to be plated, chrome-plated, tin-plated or nickel-plated to suit special applications, the surface of the steel slab must be strictly cleaned so that the coating is firmly bonded to the steel surface. Adding sodium gluconate will achieve a very good effect;

　　Pipeline; the rust resistance of bottle stickers and bottlenecks is not ideal; the trace residue after washing is not ideal for food safety （such as phosphate residue）; the washing water is discharged into public hazards.
