Process and device for producing a reactive mixture of at least two components for the production of foams

摘要

For the production of a foam-forming reactive mixture, at least one of the components disposed in separate supply tanks (1) with a stirrer (6) is charged with gas before mixing with the other component takes place. To this end the component is circulated in a separate circuit by means of a conveying unit (10), the gas is supplied in the suction region and/or compression region of the conveyor unit and the gas-component mixture is compressed. Directly following the compression zone (12) the gas-component mixture is depressurised again by means of a throttle element (11), by which means high proportions of gas can be homogeneously distributed in the liquid component. <IMAGE>
