Latest Patents

Petterson's latest patents include innovative formulations for emulsion explosives. One patent focuses on water-in-oil emulsion explosives containing a nitrate salt, specifically designed for use in boreholes. This invention utilizes ammonium nitrate, sodium nitrate, and/or calcium nitrate, achieving an untamped bulk density of 0.3-0.7 g/cm³. The explosive can be formulated as a water-in-oil emulsion where the discontinuous phase is an aqueous solution of the oxidizing salts. This type of explosive is particularly effective in small and medium-sized boreholes without the need for sensitizing or density-reducing agents.

Another patent details an emulsion explosive that is resistant to dissolution in water. This non cap-sensitive explosive can be used in cartridge form or in bulk systems. It contains 60-90 percent by weight of ammonium nitrate and calcium nitrate, along with a crystallization temperature lowering agent, preferably urea, and wax or a wax/oil mixture. The formulation also includes emulsifiers and density-reducing agents, enhancing its performance in explosive mixtures.
