Patent DE-19607582-A1 (DE)
Inventor: STUCKI FREDI DR
IPC: G01N23/14
Filed: 1996-02-29
Abstract: The invention relates to a process for monitoring a disperse system for non-dispersed impurities (16) before processing of said system into an end product. During said process, part of the disperse system is extruded before processing to form a strip (7) and the impurities in said strip are detected. To this end, weak X-rays are beamed through small areas of the strip (7) continuously or gradually and at right angles to the strip plane. The X-rays emerging from the areas of the strip through which they have passed are subsequently detected in areas. The type, number, size, shape and/ or distribution of the impurities (16) are determined by the detected rays. It is particularly advantageous that impurities inside the strip and also on the surface thereof are detected as a result of X-rays passing through the strip (7). If the impurities (16) exceed a predetermined threshold, the disperse system does not undergo further processing.
