Increase of destroying ability of pulsing jets by application of hydrodynamically-active substances

Abstract

In the report the opportunity of the increase of the work productivity of a pulsing jet generator, without the change of its design, is shown by using of water solutions of hydrodynamically-active polymers as operating fluid instead of water. The preparation of such operating fluids is provided througn erosion specially developed hard water soluble polymer compositions in mixing casette. The results of the tests on the destruction of plaster and coal-cement blocks of various durability have demonstrated, that the jet of a water solution of polymer composition has an increased destroying action in comparison with clean water at the expense of the increase of the depth of punched aperture about 1.5 — 3.5 times.
