Abstract
AbstractOn the basis of expounding the influence of the mixing proportion accuracy of solventless compound A and B on the quality of solventless compound products, this paper analyzes the proportional mixing system of solventless compound mixer. Then the output flow characteristics of the circular arc gear pump used for proportioning are analyzed, and the error of the input flow ratio of the static mixer of the solventless compound mixer caused by the output flow fluctuation of the circular arc gear pump is analyzed. By using FLUENT software, the simulation calculation is carried out for the mixing situation of fluctuating solvent-free composite A and B materials after being input into two different types of static mixers. Through the analysis of the simulation calculation results, it is found that the structure of the static mixer reduces the impact of gear pump output fluctuation on the proportioning accuracy after passing through the static mixer, but the mixing effect of different types of static mixers will be different, so when selecting the static mixer, in order to ensure reliable proportioning accuracy, reasonable selection is required.KeywordsSolventless compoundMixingProportion accuracyFlow fluctuationSimulation
