Problems solved by technology

[0003] At present, explosives for explosive welding at home and abroad are mainly mixed with dispersants such as salt, talcum powder, and expanded perlite in expanded ammonium nitrate explosives and powdered modified ammonium oil explosives to obtain low-speed explosive welding explosives. Salt makes the explosives easy to absorb moisture and agglomerate! Adding talcum powder and expanded perlite makes the explosives dusty when mixed on site, which seriously affects the health of workers. A performance is obtained by mixing latex matrix with foam plastics and carbonate mineral powder. Excellent low detonation velocity explosion welding emulsification explosion, but the production cost is high. After long-term exploration and research, it is believed that the reasonable use of low detonation velocity and high intensity explosives is most conducive to the explosive recombination of metals. However, according to the explosion theory, detonation velocity and intensity are It is directly proportional to the relationship, the higher the detonation velocity, the higher the intensity, and vice versa, so it is difficult to obtain explosives with low detonation velocity and high intensity

Description

technical field [0001] The invention relates to an explosive, in particular to a powdery emulsion explosive with low detonation velocity and small diameter. Background technique [0002] With the rapid development of modern industry, it is difficult for a single metal or alloy to meet the comprehensive performance requirements of materials in chemical, petroleum and other engineering fields. Metal composite materials made of explosive welding technology are now widely used as the source of explosive welding energy. Low detonation velocity explosive is one of the key factors affecting the performance of composite materials. [0003] At present, explosives for explosive welding at home and abroad are mainly mixed with dispersants such as salt, talcum powder, and expanded perlite in expanded ammonium nitrate explosives and powdered modified ammonium oil explosives to obtain low-speed explosive welding explosives. Salt makes the explosives easy to absorb moisture and agglomerat...
