摘要： The invention relates to a method of and an apparatus for producing a foam-forming reaction mixture of at least two liquid components which react together and which are fed continuously to a mixing zone where they are mixed together. The volumetric flow of at least one component is measured continuously both in the main pipe leading to the mixhead and also in a subsidiary pipe which branches off the main feed line between the storage for the components and its pump. This subsidiary stream serves as a source for intermittent weighing of the component so that the density of the reaction component can be periodically calculated and monitored. This helps ensure the proper mass of component entering the mixhead.An apparatus is disclosed which achieves precise dosing of the components so that a product free of defects and having the desired properties may be produced.

摘要： The present invention relates to a process and apparatus for preparing flowable reaction mixtures. The process comprises(a) measuring the volumetric rate of flow of at least one of said reactants which contains dissolved gas,(b) measuring the density of at least the same reactant noted in step (a) by radiometry successively under high pressure and low pressure,(c) determining the quantitative rate of flow of the reactant noted in steps (a) and (b) from the measurements of steps (a) and (b),(d) controlling the quantitative rate of flow of the reactant noted in steps (a) and (b) by comparing the quantitative rate determined in step (c) with a predetermined set value, and when necessary, adjusting said quantitative rate of flow,(e) controlling the amount of dissolved gas contained in the reactant noted in steps (a) and (b) by comparing the high pressure density measurement with the low pressure density measurement noted in step (b), the low pressure density measurement serving as a gauge for the gas charge, and when necessary, adjusting said amount of dissolved gas,(f) feeding said flowable reactants to a mixing zone, and(g) mixing said reactants.
