Abstract

In a pistol for mixing and spraying (polyester) resin compsns, mixing is achieved by a free running turbine driven by the hydrostatic press of the feedstock liqs. Pref. the mixt leaving the turbine chamber is further homogenised by chicanes which generate cross-flow currents as the mixt approaches the discharge nozzles. Pref. the gun is provided with ancillary flows of compressed air and acetone for rinsing the gun after use. Design does not involve a positive mechanism or introduce air to turn the mixing blade, reducing gun complexity and wt or contamination of the resin mix. Example design involves a spring loaded needle valve seating against a PTFE bush to control the resin and catalyst component flows.
