Abstract:
1. A method of increasing the strength of a dust preventing crust on an exposed surface of a mass of a dusting material made up of a conglomeration of dusting material lumps or pieces wherein the crust binds loose particles of the dusting material at an exposed surface into a cohesive whole, wherein the crust is formed from a dried liquid solution applied to the exposed outer surface of the mass of the dusting material, and wherein the solution comprises a non-ionic cellulose ether, a surfactant and water comprising the steps of: adding a plasticizer to the liquid solution prior to drying the liquid solution on an exposed surface of the mass of dusting material having a temperature less than 40° C. wherein a strength of the dust preventing crust is increased over a strength of a dust preventing crust produced from drying a fluid solution comprising the non-ionic cellulose ether, the surfactant and water.
