  • the explosive pressure distributes the sand evenly in the direction of explosion and strikes the surface around it.
  • the impact like sandblasting, cleans the surface of corrosion and other contaminants.
  • the detonating cord can be adjusted to the container or pipe size. The larger the distance cord is to the cleaning wall, the more explosive is required.
  • the sandblast density is determined by the amount of sand layer coated per meter.
  • liquids and paints as well as metal and other powders can be applied evenly.
  • the applied medium is placed in a hollow tube in the annulus between detonating cord and outer jacket. If the cord is ignited, the medium becomes explosive flung on the surrounding surfaces and sticks depending on the nature.

Abstract

L'invention concerne un cordeau détonant comportant au moins une charge explosive intérieure (2) s'étendant sur toute la longueur du cordeau détonant et au moins une enveloppe extérieure (14) s'étendant également sur toute la longueur du cordeau détonant. Afin de traiter des surfaces difficiles d'accès, il est prévu de disposer un milieu (8) pour traiter des surfaces, entre la charge explosive (2) et l'enveloppe extérieure (14).
