The Synthesis of an Aqueous Film Forming Foam Concentration and the Drainage Characteristic of the Foam

摘要

Aqueous film forming foam (AFFF) is a very effective agent for firefighting hydrocarbon fuel fires. A study was conducted to develop a small-scale test for quantifying the drainage behavior of a synthesized AFFF formulation in accordance with the requirements of MIL-24385-F. The rate of drainage was measured to increase sharply to top firstly and then to decrease significantly. Furthermore, the results revealed that there was a critical moment when the drainage of solution slowed down suddenly, and when the most part of solution had drained from the foam.
