METHOD AND DEVICE FOR CONTINUOUSLY CHARGING A LIQUID REACTIVE COMPONENT WITH A GAS FOR MAKING A FOAMY REACTIVE MIXTURE

摘要

In order to be able to charge at least one of the reactive components with small and extremely small quantities of gas with sufficient accuracy for the production of foams, in particular polyurethane foams, from liquid reaction components, the melt stream fed to a gassing vessel (1) is controlled in the sense of keeping a predetermined set value constant and the speed of the hollow agitator (15) arranged in the gassing vessel (1) is controlled in the sense of keeping the liquid level (5) constant. ……
