Abstract

The invention discloses a protection method for emulsion explosive explosion welding. Two different metal plates are overlaid. An explosive layer is laid on a metal shroud plate. Explosive explodes toform a metal composite plate. An explosive face is covered with a protection object. The protection object comprises a protection layer of the emulsion explosive, and mineral powder on the protectionlayer. The protection layer is formed by a polyvinyl plastic film or corrugated paper or brown paper. The mineral powder comprises quartz sand or bentonite or sepiolite. Through the protection object, the explosion noise of the explosive is remarkably lowered, and explosive energy is completely utilized, so that the problem that explosive energy utilization rate of explosion welding is low is solved, and meanwhile, the problem of environment pollution in the explosion welding construction process is solved. Through the protection object, the explosive consumption can be reduced by 40-60%; andexplosion noise can be reduced by 50-70%.

Description

technical field [0001] The invention relates to the technical field of metal composite plate manufacturing, in particular to a protection method for emulsion explosive explosion welding. Background technique [0002] Metal composite panels are currently widely used in petroleum, chemical, pharmaceutical, shipbuilding, electric power, metallurgy and other industries. With the continuous development of material science and equipment manufacturing technology, the application fields of metal composite panels are becoming more and more extensive. [0003] Explosive welding is commonly used for the composite of metal plates, that is, the impact force generated by explosive explosion is used to cause rapid collision between metal plates, realize the interface connection of metal plates, and form two or more layers of metal composite materials of different materials. During explosive welding, explosives are usually applied directly on the surface of the doubler board. After the expl...
