Methods of preventing scaling involving inorganic compositions, and inorganic compositions therefor

摘要

A composition including ground calcium carbonate and sodium montmorillonite. A composition including magnesium aluminum silicate and sodium montmorillonite. An aqueous pulp slurry, including wood pulp, metal cations, anions, and about 50 to 500 ppm of an anti-scalant comprised of at least one of magnesium aluminum silicate, hydrated magnesium aluminum silicate, saponite, sepiolite, calcium carbonate, magnesium carbonate, ferrous carbonate, manganese carbonate, dolomite, hectorite, amorphous magnesium silicate, and zinc carbonate.
