Abstract

A personal, portable unit having control, mixing and dosing facilities is used for the prodn. of solid synthetic foams. The action of the unit is controlled by pneumatically operated valves and it contains a separate channel for blow-down and cleaning. The soln. used in foam prodn. is disposed and mixed with the foam producing gas by a revolving disc which is set in motion by the liq. and gas flow. The dispersed material is passed through the foam producing section to be converted into a pourable form. A convergent circular stream of this, is intimately mixed with a circular, divergent stream of a resin soln., without affecting the level of dispersion. - Polycondensation starts and reaches a required level while passing through the dosing section. The setting of the control unit's choke-valve regulates the vol. of the gas required for foam prodn. This depends on the type of starting materials used and the prod. to be made and is established in preliminary experiments.
