ACUMER™ 1850

Acumer™ 1850 is manufactured by DOW Chemical (Mid South Chemical is a “certified” repackager of Acumer™ products)

 

Thermally stable, polycarboxylate dispersant for boiler treatment

Description

ACUMER™ 1850 is a low molecular weight polycarboxylate for general purpose scale inhibition within water systems. ACUMER™ 1850 is thermally very stable and is highly effective as a sludge dispersant and scale control polymer in boilers.

Used in:

  • Scale inhibition in open recirculating cooling circuits
  • Dispersant for all types of cooling circuits
  • Dispersant for all types of cooling circuits
    Dispersant for boiler sludge control in high pressure systems

Advantages

  • Good anti-scaling efficiency at low dosage over a wide range of pH, water hardness and temperature conditions
  • Very good thermal stability
  • Very strong dispersant activity
  • Conforms with a number of FDA boiler treatment regulations
  • Contains no phosphorus – meets discharge water legislation requirements
  • Conforms with a number of FDA boiler treatment regulations
  • Exceptional stability in the presence of hypochlorite

Chemistry and Mode of Action

ACUMER 1850 is a low molecular weight polycarboxylate with a selected molecular weight around 30000 to optimize the dispersant performance. It acts 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.

Performance

ACUMER 1850 is a general purpose scale inhibitor and dispersant. It is effective to inhibit scale deposition on equipment surfaces. It acts against precipitation and deposition of calcium carbonate, calcium sulphate and other sparingly soluble salts.

ACUMER 1850 is thermally very stable. There is no weight loss up to 450°C (thermogravimetric analysis). It is particularly recommended to use ACUMER 1850 as sludge dispersant and scale control polymer in boiler, even in high pressure boilers.

Applications

  • Industrial Water Treatment
  • Scale inhibition in open recirculating cooling circuits
  • Dispersant for all types of cooling circuits
  • Dispersant for boiler sludge control

Benefits of ACUMER 1850

Exhibits exceptional stability in the presence of hypochlorite.

Shows good anti-scaling efficiency at low dosage over a wide range of pH, water hardness and temperature conditions.

Exhibits a very good thermal stability.

Offers a very strong dispersant activity.
