Aqueous solution of acrylic copolymer with low molecular weight, used as a crust inhibitor (calcium and/or magnesium carbonates) in industrial water cooling systems, or as a dispersing agent in the process of pulp obtaining from timber.
Function and range of use
It acts on the growth mechanism of crystals and on the nucleation phenomenon of carbonate type insoluble salts (calcium, magnesium, etc.) and prevents their building-up on the contact surfaces. In this way it increases overhaul free service life of pipes, tanks and treatment systems in industrial water cooling circuits, while reducing the time and costs of treatments during overhauls. Usage dosage varies depending on the nature of the treated water (hardness, total solid concentration in the system, etc.) between 5 and 50 ppm, typically 5-10 ppm.
In the process of pulp obtaining it acts as an anti-incrustant/dispersing agent and inhibits calcium carbonate, calcium sulfate and barium sulfate type building-ups on various equipment (Kamyr digesters, scrubbers, black lye evaporators, etc.).
