The following is a detailed description of the test method for the performance parameters to be tested:
لمعان: Use a gloss meter to measure the gloss of the cover finish to evaluate the gloss effect and gloss stability of the surface.
فرق اللون: Use a color comparator to measure the color difference of the mask finish to evaluate its color consistency and accuracy.
صلابة: Using the pencil hardness measurement method, a scratch test with a pencil is performed to evaluate the hardness and wear resistance of the finish.
اللزوجة: The viscosity of the finish is measured using a viscometer to assess the brushing performance and quality of the coating.
وقت التجفيف: The drying time of the cover finish was measured using the oven method to evaluate its construction efficiency and coating quality.
مقاومة الطقس: The weather resistance of the finish was evaluated using an artificial accelerated aging test to evaluate its oxidation resistance, UV resistance and other properties under different climatic conditions.
