Performance testing content of polishing compounds
Physical Performance Testing
-Particle size distribution: Using a laser particle size analyzer to determine the size and distribution of abrasive particles, this indicator is directly related to polishing efficiency and workpiece surface roughness.
-Hardness: Evaluate the hardness of abrasive particles to ensure that they can effectively remove the surface layer of the processed material.
chemical composition
-Abrasive composition analysis: Using X-ray fluorescence spectroscopy, X-ray diffraction, or magnifying glass, analyze the types and purity of the main abrasives (such as alumina, ceria, silica, etc.) in the polishing agent.
-Chemical additive analysis: By using techniques such as high-performance liquid chromatography and gas chromatography-mass spectrometry, the types and contents of dispersants, surfactants, corrosion inhibitors, and other additives are detected.
-Impurity element analysis: Determine the content of metal impurities such as iron, copper, nickel, etc. These impurities may scratch the precision surface or cause contamination during the polishing process.
Polishing effect evaluation
-Surface roughness: The surface roughness of the polished workpiece is measured using a profilometer or atomic force microscope, and this indicator is the core basis for evaluating the polishing effect.
-Glossiness: The specular reflection ability of the polished surface is detected by a glossiness meter.
-Material removal rate: Under standard conditions, measure the weight or thickness of material removed by the polishing compound color per unit time to evaluate its polishing efficiency.
-Surface defect analysis: Use an optical microscope or electron microscope to observe whether there are scratches, pitting, corrosion and other defects on the polished surface.
-Biodegradability: Evaluate the degradation ability of Liquid polish waste liquid in the natural environment to measure its environmental friendliness.
