Viscosity Measurements of Malleable Explosive (MEX), a New Demolition Explosive

Abstract

The rheological characterisation of Malleable Explosive (MEX), a new explosive intended for demolition use, is presented. A Brookfield viscometer with T-bar spindles and Helipath stand is used to investigate the viscosity of MEX at shear rates similar to those encountered during extrusion of the material from a dispenser. The indicated viscosity is sensitive to the position, type and speed of spindle used for the determination. The viscosity is determined over the temperature range -16C to 60C and is particulary temperature sensitive only below 0C, whereupon the viscosity rises rapidly. From 0C to 40C, the viscosity decrease to a value which is dependent upon the temperature and shear rate, then remains constant or increases slightly with further heating to 60C. A laboratory method suitable for transfer to the production factory in the event that MEX proceeds to full production is detailed.
