Sodium Gluconate as Water Stabilizer

In industry, sodium gluconate admixture can be used as a variety of efficient additives, such as concrete water reducer, metal chelator, cement retarder, metal corrosion inhibitor. Because of its properties, sodium gluconate is often used as a water stabilizer. Water quality stabilizer is a chemical agent added to circulating cooling water to prevent corrosion and scaling of cooling water to equipment.

As a water stabilizer, sodium gluconate has the functions of corrosion inhibitor, cleaner, and chelator. Widely used in industrial circulating water, boiler and heating water, oilfield water injection, reverse osmosis membrane and other systems. It has the following characteristics.

1. Good coordination of elements. Sodium gluconate has very good chelation, can cooperate with molybdenum, silicon, phosphorus, tungsten, nitrite, etc. Because the coordination performance of sodium gluconate is very good, the corrosion inhibition effect of metal parts and concrete reinforcement is greatly improved.

2. When used as a corrosion inhibitor, the performance increases with ambient temperature. When the performance of the general corrosion inhibitor decreases with the increase of temperature, sodium gluconate can improve the corrosion inhibition effect with the increase of temperature in a certain range of temperatures. For the variable temperature system from low temperature to high temperature, the corrosion inhibition effect is very ideal.

3. Very strong scale inhibition. The scale inhibition ability used by metal is one of the aspects that determine the performance of metal. The stronger the scale inhibition ability, the longer the service life of the parts in the service process. Sodium gluconate admixture has a strong complexation ability with calcium, magnesium and iron salts, and a strong scale inhibition ability, especially for Fe3+ excellent chelation, can be used in the whole range of PH value.

4. Superior environmental protection effect. Using sodium gluconate as corrosion and scale inhibitor of circulating water can avoid the formation of pollutants and achieve the effect of eliminating public hazards. The problem of excessive discharge of waste in production leads to the breeding of various harmful substances was solved.
