Sodium Gluconate is widely used in industry. Sodium gluconate can be used as high-efficiency chelating agent in construction, textile printing and dyeing, metal surface treatment and water treatment industries, steel surface cleaning agent, glass bottle cleaning agent, aluminum oxide coloring in electroplating industry, glucose Sodium is used as high-efficiency retarder, high-efficiency water-reducing agent, etc. in the concrete industry.
The use of sodium gluconate in the industry is very common, basically including all products, the most common is the role in the construction field, Bailin Group introduces its corrosion inhibition effect on steel bars in concrete.
According to the application of electrochemical impedance spectroscopy, it is concluded that:
under normal circumstances, the concrete pore liquid is highly alkaline, and sodium gluconate competes with chloride ions on the surface of the steel bar to form a passivation film on the surface of the steel bar in the concrete. Corroded. Gluconic acid and its salts are widely used in the anti-corrosion of iron and low carbon steel in condensate water systems. These corrosion inhibitors are efficient and environmentally friendly. In near-neutral media, sodium gluconate can successfully prevent tin, iron and low carbon steel. Corrosion of carbon steel, it is a kind of corrosion inhibitor product that has good corrosion inhibition effect on steel in alkaline medium
Used as water stabilizer:
Due to its excellent corrosion and scale inhibition properties, sodium gluconate is widely used as a water stabilizer, for example, as a treatment agent for circulating cooling water systems in petrochemical enterprises, low-pressure boilers, and cooling water systems for internal combustion engines. Because sodium gluconate has the following specific advantages: it has obvious coordination effect. It is suitable for formulas such as molybdenum, silicon, phosphorus, tungsten, nitrite, etc. Due to the influence of the coordination effect, the corrosion inhibition effect is greatly improved. The corrosion inhibition rate of sodium gluconate increases with the increase of temperature. Generally, the corrosion inhibition rate decreases with the increase of temperature, or even loses its effect completely.
But sodium gluconate is just the opposite. The corrosion inhibition rate increases with the increase of temperature within a certain range. For example, in the test of carbon steel and other materials, when the temperature rises from 77°C to 120°F, the buffer rate increases by 5% on average above.
Therefore, the unique properties of sodium gluconate are ideal for use as a corrosion inhibitor for higher temperature systems or variable temperature systems from low temperature to high temperature.
Strong scale inhibition ability: It has strong complexing ability for calcium, magnesium and iron salts, so the scale inhibition ability is very strong, especially for Fe3+, it has excellent chelating effect, and even has an effect in the whole PH range.
Eliminate pollution. The use of sodium gluconate as a corrosion and scale inhibitor for circulating cooling water can eliminate pollution, which is an incomparable advantage of other corrosion and scale inhibitors currently used.
Advantages of the Sodium gluconate as a corrosion and scale inhibitor：
1) Sodium gluconate has good compatibility with other chemicals in circulating system
2) The corrosion inhibition rate of sodium gluconate will increase with increasing temperature, most of corrosion inhibitors are opposite, some would be useless in high temperature.
3) Sodium gluconate is fermented from corn starch, which is natural and no harm to environment. It is pollution-free, this is the advantage that the corrosion inhibitor used at present can’t compare with. It is one of the cheapest organic synthetic chemical which is widely used as corrosion and scale inhibitor in circulating cooling water in all over the world
4) High purity with good function, Min 99% purity
