Judgment of the appearance of powder coating orange peel

can visually evaluate and compare the appearance of orange peels using mechanical methods of the shape gauge or through ripple scanning(1) visualthe template is placed under a two-tube fluorescent lamp in this testThe template's reflective light source can be obtained by placing the template appropriatelyQualitative analysis of the clarity of reflected light visually evaluates the properties of flow and levelingIn the case of poor liquidity (orange peel), two fluorescent tubes look blurry and highly liquid products can achieve clear reflections(2) "form measurement"in this method by using the offset of a highly sensitive probe to record the surface shapeThis allows for a quick distinction between roughness, orange peel, and fluctuations caused by shrinkholes, pinholes or dirt3 Byk-Gardiner's "Ripple Scan Orange Instrument Measurement"used to simulate visual judgment by focusing "ripple scanning" on the surfaceThe instrument is moved more than 10cm on the sample surface to scan the surface of the sampleThis method uses a laser light source to irradiate the surface of the template from a 60-degree angle and then measure the reflected light at a relatively similar angleThe signal detected the most when the beam hits the peak end or trough on the surface, and the signal that is recorded when the beam hits the peak slopeRipple scanning measures the visually visible optical surface finish, while the shape-measurement instrument measures the mechanical shape finish that people can feel
