Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of inhibiting the release of dust from a pile of particulate material, the method comprising the step of applying to the exposed surface of the pile an emulsion composition comprising water, 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 composition does not pass significant amounts of water to the pile. 2. The method…
