Quick-Setting Foam Research Support and Spray-Nozzle Sub-System.

摘要

A polyurethane foam formulation is developed and a special spray nozzle subsystem is designed to meet the requirements of a lightweight physical bridging system which serves as a self-contained,man portable back pack spray system providing a crossing over minefields for troops. The foam formulation has improved load bearing capacity at short cure times and operation at extreme temperatures. (Author,modified-PL)
