COMPOSITION FOR DUST CONTROL AND IMPROVED MATERIAL HANDLING

摘要

The invention provides methods and compositions for blends of glycerin and polyvinyl acetate emulsions which effectively decrease the dust forming tendency of particulate materials such as mineral fertilizer(s). These blends also reduce the caking tendency of mineral fertilizer(s), helping to maintain a free flowing material. Formulations based on these components, possibly including other additives, may also be useful for dust control and/or anticaking on other particulate materials including fertilizers, ores, coal, grain, etc.

主权项

1. A composition comprising
a pile of particulate material comprising a dust generating material; polyvinyl acetate; and glycerin,wherein the ratio of polyvinyl acetate to glycerin by weight in the composition is between 100:1 and 1:10, and wherein the dust forming tendency of the composition and the caking tendency of the composition are reduced compared to the pile of particulate material.
