Why use sodium gluconate as corrosion scale inhibitor? First of all, sodium gluconate has many functions and functions, so it can solve many problems, which is closely related to its advantages.
What are the advantages and characteristics of sodium gluconate as corrosion inhibitor and scale inhibitor?
1. Obvious synergistic effect. Sodium gluconate is a broad-spectrum corrosion inhibitor and scale inhibitor.
It can be used not only in molybdate formulation to enhance the corrosion inhibition effect of molybdate, but also in silicon, phosphorus, boron, tungsten and nitrite formulation.
2. The corrosion inhibition rate increases with the increase of temperature. For most corrosion inhibitors, with the increase of temperature, the corrosion inhibition rate generally decreases, and sometimes even completely loses its inhibition effect.
For example, when the water temperature reaches 90 C, the main phosphorus inhibitors, sodium hexametaphosphate and sodium tripolyphosphate, almost lose their corrosion inhibition ability due to hydrolysis and degradation. For example, when the water temperature reaches above 50 C, the inhibition effect of organic amine inhibitors is basically lost.
The inhibition rate of sodium gluconate was inversely proportional to temperature. Under certain conditions, it will rise.
3. It has good complexing property and scale inhibition effect.
4. It will not cause secondary pollution of water quality, and the price is low. However, when sodium gluconate is used as corrosion inhibitor, it can promote algae reproduction because of its rich nutrition, which is a problem to be noticed.
