Anti-scalants can inhibit inorganic scale formation
(e.g., CaCO3, CaSO4, BaSO4) especially at metal surfaces in
industrial boilers, cooling towers, mining and mineral processing,
and oil fields. Scale formation is inhibited by three mechanisms:
1) interference with the growth of scale crystals, 2) dispersion
of particles or prevention of their agglomeration into larger
adherent particles, and 3) chelation or complexation of inorganic
ions.

| Dispersants are used in many industrial products
and processes that require solids be mixed in a finely divided
state within a liquid medium and remain stable for a period
of time prior to and during their use. Our copolymers and
polycarboxylates are a series of dispersants that provide
stability to dispersions at low dosages. The properties of
these polycarboxylates will allow them to adsorb efficiently
onto a solid substrate and be maintained in a stable dispersion
state through a complex and system-dependent mechanism involving
electrostatic repulsion and/or steric hinderance. |
