    The appearance of orange peel can be evaluated and compared visually or mechanically using a shape meter or by a ripple scan (1) visual inspection: in this test, the sample plate is placed under the double tube fluorescent lamp The reflection light of the template can be obtained by placing the template properly Qualitative analysis of the sharpness of the reflected light allows a visual assessment of the flow and levelling properties In the case of poor fluidity (orange peel), the two fluorescent tubes look fuzzy and unclear, while the products with high fluidity can obtain clear reflection (2) "profile measurement method": in this method, the surface shape is recorded by the offset of a highly sensitive probe Thus, the difference between rough, orange peel caused by shrinkage cavity, pinhole or dirty dirt and fluctuation caused by poor flow can be quickly distinguished (3) BYK gardener "ripple scanning orange peel measuring method" is designed to simulate visual judgment by focusing on the surface of the "ripple scanning" Move the instrument more than 10cm on the sample surface to scan the sample surface In this method, a laser source is used to irradiate the surface of the sample plate at an angle of 60 ° and then measure the reflected light at the same relative angle The detected signal is the largest when the beam hits the peak or valley on the surface, and the recorded signal is the smallest when the beam hits the peak slope The wave scanning measures the optical surface finish that people can see visually, while the shape measuring instrument measures the mechanical surface finish that people can feel.
