TH2025EX - Stable ammonium nitrate / emulsion explosives and emulsions for use in such explosives. - Google Patents

Abstract

Explosives that are activated mixtures of water-in-oil emulsions and inorganic nitrates, such as AN particles, such as AN or ANFO pellets, have improved stability when their structure obstructs the Water is lost from the aqueous phase of the emulsion and the transfer of water through the oil phase to the nitrate particles is used by emulsifiers containing fatty acid salts, for example. Made there during the emulsion It is a more suitable method of making structures that stabilize the mixture. Emulsion / Nitrate mixtures Stabilized in this way provides a packaged product. Stable when stored is desirable New low viscosity emulsion / nitrate mixtures with all the essential oils needed to balance the mixtures with oxygen and an anhydrous emulsifiers. A moderately large amount of ionic that stabilizes the emulsion structure forms an unpackaged product. That is more suitable due to being optimized for more pumping Pumping the stabilized mixture through an annular stream of aqueous lubricant is beneficial.
