SANCORE POLII 1355: Acrylic Acid, SHP Co-polymer (54-56%)

SANCORE POLII 1355 is a highly effective scale inhibitor in industrial water treatment.

Application:
Carbonates and sulfates scale inhibitor. Particularly effective for harsh running conditions copolymer (high pH, high temperature, high scalants concentration).

SANCORE POLII 1355 inhibits scale build up on surfaces through at least three mechanisms:

• Solubility enhancement or threshold effect, which reduces precipitation of sparingly soluble inorganic salts.
• Crystal modification, which deforms the growing inorganic salt crystal to give small, irregular, readily fractured crystals that do not adhere well to surfaces.
• Dispersing activity, which prevents precipitated crystals or other inorganic particulates from agglomerating and depositing on surfaces.

SANCORE POLII 1748: Acrylic Homopolymer      

Application: Scale inhibitor for carbonates, sulfates and sparingly soluble salts for acidic formulations

Properties:

It is a low molecular weight polyacrylate with excellent inhibition effect for calcium carbonate in industry circulating cool water system; It can also be used as antiscalant and dispersant in Boiler and Oil field water systems; SANCORE POLII 1748shows good anti-scale efficiency at low dosage over a wide range of pH, hardness and temperature conditions.

Usage:

SANCORE POLII 1748 can be used alone with the general dosage 10-30mg/L. When used with other water treatment chemicals in formulations, the dosage should be determined by experiment according to the water and equipment condition.

SANCORE POLII 1725: Acrylic Acid Homopolymer (24-26%)

SANCORE POLII 1725 is a polyacrylic acid hydrophilic colloidal solution, similar in properties to water-soluble natural gums. It is supplied as a clear, colorless, viscous stable solution. Applications include the modification of aqueous formulations for such end uses as cleaners, binders, adhesives, and emulsion paints. The sodium, potassium, and ammonium salts are effective thickeners and dispersants useful in both natural and synthetic latex systems.

Application:

• Surface treatment application. (5% solution)

The sodium, potassium, and ammonium salts of SANCORE POLII 1725 acid is an effective dispersant for various pigments such as zinc oxide, titanium dioxide, calcium carbonate, and barium sulfate. The lack of color of these dispersants offers an advantage in making dispersions in which darkly colored natural dispersants may affect shading. Because of their hydrolytic and thermal stability, the alkali salts of SANCORE POLII 1725 acid retain their dispersant activity for prolonged periods.

Application: 

SANCORE POLII 1337 provides superior stabilization of calcium phosphate, zinc and calcium carbonate. It also prevents calcium sulfate and calcium oxalate scales, even in extreme pH environments (pH 4-10).

In addition, SANCORE POLII 1337 is a strong dispersant in keeping the silt and commonly encountered inorganic particles suspended and in preventing their settling out onto heat transfer surfaces.

Industrial water treatment:

• Dispersant for boiler sludge control

Pulp and paper process:

• Dispersant and scale inhibitor
