Dust suppression with elastomer-containing foam

TL;DR: An improved non-viscous aqueous dust control solution which includes a polyvinyl alcohol and boric acid was presented in this paper. The improved solution may be spray applied or applied as a foam.

TL;DR: In this article, water insoluble elastomeric polymers are combined with oil and the combination is sprayed or applied in a foam carrier to dust particles to inhibit dissemination thereof which would otherwise occur by windage or transit motion.

TL;DR: In this paper, a method of suppressing dust generation emanating from cement clinker dust by applying a foamed dust control treatment was proposed, where foam is provided with an effective defoaming agent which, upon slurrying of the clinker and other ingredients (e.g., sand, gypsum, aggregate) to form the desired mortar, inhibits foam formation in the mortar, thus not significantly increasing air entrapped in the slurried mortar.

TL;DR: A stable foam having foam bubble diameters of 0.005-0.015 inches and being comprised of from about 10-30 wt. % of a brine freeze control agent selected from the group consisting of sodium chloride, calcium chloride, magnesium chloride, potassium chloride, borax, potassium thiocyanate, potassium acetate, sodium acetate and sodium nitrite is applied to solid, particulate materials such as coal or mineral ores to inhibit freezing and improve handleability characteristics as discussed by the authors.

TL;DR: In this article, the authors describe a very dilute aqueous solution containing a surfactant plus a synthetic gum in a concentration from about 15 percent to about 45 percent of the weight of the surfactants.

TL;DR: The dissemination of fugitive dust particles into the atmosphere is reduced by treating the particles with an aqueous solution of alkylphenoxy polyethoxy ethanol and copolymer of ethylene oxide and propylene oxide.

TL;DR: The surface of a mass of finely divided particulate matter is treated by applying to the surface a combination of an organic polymer latex and a silicone to provide a water repellant surface as discussed by the authors.
