摘要： A low energy fuse is extruded as a single ply primary tube 1 from a plastic resin blend with particulate energetic material 2 being internally distributed in a manner known per se, said resin blend comprising a major amount of an orientable polymer, for example, linear low density polyethylene to provide structural integrity and a minor amount of a modifier to impart enhanced particle retentive properties to the tube and preferably also containing a polymer or copolymer to impart melt strength and aid in tube extrusion.

摘要： A modified explosive shock tube is provided which has a lateral energy output and hence may be used as a trunk line in a non-electric blasting network. The modified shock tube comprises a hollow, flexible plastic tube having a layer of energy-producing material on its inner surface and also having at intervals along its length, cuts or slits which penetrate the tube wall. The area of the slits has an overcovering of a waterproof material. When energized, the tube will burst at the area of the slits to release energy in a direction lateral to the tube axis.

摘要： Low energy explosive shock tubing is provided which consists of a two-ply, inner and outer layer plastic tube having a plurality of lengthwise textile filaments bonded into the interface between the plastic layers. The textile filaments are chosen for their low elongation properties and the resultant shock tube resists stretching especially in warm borehole environments.
摘要翻译： 提供了低能量的爆炸性冲击管，由两层，内层和外层塑料管组成，其具有多个长度方向的织物长丝，其结合到塑料层之间的界面。 选择纺织长丝为其低伸长性能，并且所得的冲击管特别是在温暖的钻孔环境中抵抗拉伸。
