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.
期刊介绍：
Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
