Chelants are the prime additives in a solubilizing boiler water treatment program. Chelants have the ability to complex many cations (hardness and heavy metals under boiler water conditions). They accomplish this by locking metals into a soluble organic ring structure. The chelated cations do not deposit in the boiler.Get Price
As a polymer is used in the boiler water, it will absorb a heavy water layer, which also carries an electrical charge. Through this phenomenon, the polymer functions in two ways: 1. The electrical charge of the polymer that is absorbed on to the particles is identical (all negative or all positive) causing them to repel each other. 2.Get Price
