Rheological Properties of Thickened Liquids.

摘要

In order to improve the performance of flame thrower fuels, the rheological properties of thickened liquids were investigated. The fluids were of two main types: solutions of a basic aluminum soap in gasoline, and methacrylate copolymers also dissolved in gasoline, with or without the addition of a soap such as sodium stearate. The prime requirements for a flame thrower thickened fluid is pseudo plasticity. Measurements of the apparent viscosity, modulus of rigidity, work hardening, thixotropy, thixotropy and other properties of a large number of thickened fluids were made using a variety of instruments. Measurements were made with the normal viscosimetric techniques, at frequencies of from 5 to 600 cps and under suddenly imposed shock. A limited number of practical tests were made and for unignited flame thrower studies a 1/8" 37 deg conical nozzle was installed. A number of M56 incendiary bombs were filled with a widely varying liquids and the results on static ignition studied.
