Abstract
Various embodiments for systems and methods for dust suppression in which a mixture of polymer and water is applied to a surface or mixed with particles that prevents the generation of dust after the water evaporates are disclosed.
Claims14
A method for dust suppression comprising applying a solution including a liquid amphiphilic polymer to dust to establish a degree of particle bonding between the dust and the liquid amphiphilic polymer and maintain the wettability of the dust over time;
- wherein the degree of particle bonding between the dust and the liquid amphiphilic polymer and wettability of the dust is maintained for at least two weeks, wherein the concentration of said liquid amphiphilic polymers is in the range of greater than about 1% to about 5%, by volume, and wherein the liquid amphiphilic polymer is a Pluronic® poloxamer selected from 25R4, 31R1, L10, L31, L35, L44, L62 LF, and L92 or a Polyethylene glycol (PEG) selected from PEG200, PEG300, PEG400, and PEG600.
