Low-pressure mixing technology in PUR processing - The relationship between mixing quality and process parameters
The quality with which PUR components can be mixed together in a high-frequency mixer depends on various process parameters, such as throughput, rotary frequency and mixing position. An objective assessment of the mixing quality can be obtained by colouring the components and subsequently analysing the grey scale value.
