Abstract

Now there is still no unified standard for the evaluation of mixing uniformity in the abrasives industry. Taking the powders commonly used in resin bonded grinding wheels as the research objects, a simple sampling specification and uniformity statistical method were designed in this paper. By means of various detection methods, the homogeneity of the mixture was evaluated from macroscopic and microscopic perspectives. The results showed that organic solvent method was suitable for macroscopic analysis of resin bond. X-ray fluorescence spectrometry (XRF) was suitable for macroscopic analysis of fillers. Calcination method was suitable for macroscopic analysis of substances which can be oxidized in the air. The optical microscopy method was suitable for on-line real-time control of the raw material powders. Scanning electron microscope (SEM) observation was suitable for micro-uniformity analysis.
