Boiler water polymers function as dispersants and weak sequestrants. Phosphate chemistry works by precipitating calcium as any of several insoluble calcium phosphate compounds. This material can deposit on tube and drum surfaces, and its buildup can impede heat transfer on generating tubes and cause tube failures.

dispersants can also be used in certain plastics applications, such as plasticizer dispersions. Thermoplastic Masterbatch and Compounding benefits solplus Dp310 and solsperse 21000 hyperdispersants are recommended for the dispersion of pigments and fillers in thermoplastic masterbatch and compound applications.

MINING AND SLURRY TREATMENT. When mining, the extraction of calcium, phosphate, kaolin, and sand often requires the minerals to be mixed with water to form a slurry.. A slurry is a mixture of a solid and liquid which has a natural tendency to separate. If separation does occur several transportation, storage, and manufacturing problems can arise, including difficulty pumping or problems with ...

Compound these changes with the inevitable variation in localized impurities and we have a variety of materials that the industrial world knows simply as calcium carbonate. Several basic crystal forms of calcium carbonate are found, the most common being calcite and aragonite. Dolomite and vaterite, which are very unstable, also occur naturally.

Calcium carbonate powders are prepared by two different methods—attrition and precipitation. The precipitated form is available in several crystal habits and sizes and has a much finer particle size distribution, for which reason it is of most interest in this case. Calcium carbonate is generally considered nontoxic.

It has been found generally that the inorganic polyphosphate compounds are the most effective dispersants for the paper additives, such as, calcium carbonate. Other inorganic compounds such as silicates are much less effective. The best dispersant as well as the optimum concentration may vary between various paper additives.
