Abstract: A method of plugging channels of a honeycomb body and a honeycomb body including plugged channels. The method includes applying a shear force to a plugging mixture including a plurality of inorganic particles, clay, and a liquid vehicle to alter the viscosity of the plugging mixture from a first viscosity prior to the vibrating to a second viscosity which is less than the first viscosity. A honeycomb body is placed into contact with the plugging mixture such that a portion of the plugging mixture having the second viscosity flows into the plurality of channels. Application of the shear force is stopped or reduced to increase the viscosity of the portion of the plugging mixture in the plurality of channels to greater than the first viscosity.

Abstract: A method for reducing ammonia and other gases from the detonation of explosives. A method in accordance with the invention comprises placing an ion exchange agent such as a natural occurring zeolite mineral like clinoptilolite around the blast area, over the top of the blast area, under the area receiving the blasted material, within the blast holes or chambers holding the explosives, in the water covering the blast area, over the top of the blasted material, mixed in the explosives and the like. The ammonia and various other gases exchange into the lattice of the ion exchange agent where they become insoluble. This creates a healthier work environment for workers and reduces environmental pollution.
