Chemistry and Mode of Action

ACUMER 1000 is a low molecular weight polyacrylate with a selected molecular weight around 2000 to optimize the anti-scale performance through at least three mechanisms:

  • Solubility enhancement by threshold effect, which reduces precipitation of low solubility inorganic salts (calcium carbonate in particular).
  • Crystal modification, which deforms the growing inorganic salt crystal to give small, irregular, readily fractured crystals that do not adhere well to surfaces and can be easily removed during cleaning operations.
  • Dispersing activity, which prevents precipitated crystals or other inorganic particles from agglomerating and depositing on surfaces.

Anti-Precipitation Performance
ACUMER 1000 polymer is a general purpose scale inhibitor as it is effective to inhibit precipitation of calcium carbonate, calcium oxalate, calcium sulfate, barium sulfate, and other low solubility salts.

 

Applications

  • Industrial water treatment:                                                                                         

   –Scale inhibition in open recirculating cooling circuits (CaCO3 scale in particular).               

   –Dispersant for boiler sludge control.

  • Oil field water treatment for preventing scale in both formation and production equipment.

 

Benefits of ACUMER 1000

  • Contain no phosphorus, making its use acceptable where legislation requires that discharge waters contain low or no phosphorus.
  • Exhibit exceptional stability in the presence of hypochlorite.
  • Show good anti-scaling efficiency at low dosage over a wide range of pH, water hardness and temperature conditions.
  • Show a higher degree of solubility in presence of Ca2+ than other higher molecular weight homopolymers.
  • Offer a strong dispersant activity contrarily to phosphonates.


Storage Recommendation
Freezing or long term cold storage of ACUMER 1000 may cause some separation of the components. Although product performance is not impaired as long as the whole container is heated and well mixed, it is recommended to keep ACUMER 1000 from freezing.
