    Low-energy fuse in the form of a plastic tube the inner surface of which is coated with explosive. In order to prevent the explosive from being dislodged, the plastic tube is of sandwich-type, the outer part of which will withstand mechanical stress and the inner part of which has such adhesion to the explosive agent that this is only dislodged by a shock wave.

    one
    The invention relates to blasting means, in particular, to the implementation of fuses that transmit a shock wave.
    Fuses are known that contain a plastic tubular casing, which is coated inside with a layer of powdered explosive consisting of 91% cyclotetramethylene tetranitramine and 9% aluminum powder 1,
    When igniting such a fuse, a shock wave passes through one layer of the explosive, which is. ra reaches the other end of the fuse. In connection with insufficient gheghese, part of the explosive is scattered from the inner surface of the tubular casing during storage or transportation, which leads to the interruption of the propagation of the shock wave and the failure of the normal operation of the igniter.
    The aim of the invention is to improve the reliability of the propagation of a shock wave.
    This is achieved by the fact that in the fuse containing a plastic tubular sheath, covered inside with a layer of powdered explosive, a plastic tubular sheath
    the shell is made of two count
    cemented parts from which nah is made of polyamide, and
    internally from Surlin
    EMOrd by DuPont).
    At the same time outer ringband
    on
    part of the tubular casing may be ol4l made of polypropene or
    butene.
    In the drawing, the isobersik fuse,
    cross-section
    The fuse consists of an outer
    a 15 shaped part 1, made of a polysmide, and an inner ring
    different parts 2 made from rlin. On the inner surface of the inner ring-shaped part
    20 layer 3 powdered explosive
    wow substance.
    Benefit ar application
    polyami, 1a. high enough
    Svenin, who has a choir
    25 adhesive properties, true
    the fuse has a higher level
    transfer of shock waves due to
    shtheni shedding an explosive thing and resistance to external damage
    E30 ny m
    The use of the inner tube with the adhesive surface of the shell allows the inner surface to be covered with an explosive powder in an amount up to 7 g / m. Previously used tubing allowed coating up to about 4 g / m. It is good; the neck's adhesive property of the plastic tube makes it possible to store it for a long time and be subjected to rough handling during the process of fitting the plastic tube, while the powder of the explosive substance does not lag behind the surface of the shell.
