Anwendung von Mikrohohlglaskugeln in der Ex

Application of hollow glass microspheres in the explosive Appearance: White fine powder Particle shape: Hollow sphere Composition: Soda lime borosilicate quality True density: 0.15-0.25g/cc particle size: about 15-110μm Compressive strength: about 1.5-7MPa Thermal conductivity: 0.03-0.06w/m.k The density regulators commonly used in the Emulsion explosives are expanded perlite and chemical blowing agents. The first one has shortcomings of explosive effects limited by its size, strength and oil resistance, lower explosive performance, short-term storage; The second one has the disadvantage of the density of explosives difficult to control, short-term storage and aftereffects. With addition of hollow glassmicrospheres in the emulsion explosive, all its shortcomings and disadvantages can be overcome. The performance of the detonation is greatly improved and the storage stability is significantly increased. It mainly adopts the sensitization of hollow glass microspheres. Hollow glassmicrospheres have advantages of low density, low thermal conductivity, low oil absorption rate, particle size and chemical composition control, which makes it highly suitable as emulsion explosive sensitizer. It has significantly improved with less and detonation performance, enhance the storage stability characteristics.
