Interaction of a Water Medium and a Solid Composite Gas-Producing Formulation Based on Butyl Rubber

The authors have given experimental data on the change in the mass of a cylindrical specimen of a solid composite gas-producing formulation based on butyl rubber and ammonium perchlorate as a function of the holding time in seawater. The depth of surface washout of the oxidant has been assessed for these conditions. Consideration has been given to the questions of reduction of the gas-producing power of relevant full-scale blocks as applied to their possible use for blowing of deep-sea ship-raising pontoons depending on the residence time in the water medium, which is determined by the period of preparatory work.
