Superiority
Product Description:
- Polyphosphates are one of the earliest, most widely used and most economical cooling water corrosion inhibitors. Polyphosphate in addition to the use of corrosion inhibitors, can also be used as scale inhibitors.
- In order to improve the effect of corrosion inhibition and reduce the amount of polyphosphate, usually used in conjunction with zinc salts, molybdate, organic phosphates and other corrosion inhibitors.
- Polyphosphate is suitable for water temperature below 50℃. Stay in the water should not be too long. Otherwise, the hydrolysis of multiplied phosphate generates orthophosphate, which will increase the tendency to produce phosphate scale.
