Caitu influence on the measurement area: painted lime detection area is larger volumes, the test results, the better representative color coated paper, will also improve the detection accuracy. Thickness of the magnetic detection probe diameter is generally 1.5 mm, detection probe micrometer diameter 6.3 mm, length measuring microscope law generally not more than 1 mm, and measuring the diameter DJH law generally are about 1 mm. Therefore, under the same conditions, these four kinds of detection methods micrometer assay results of the least volatile. Color-coated substrates typically include cold rolled steel, galvanized steel, galvanized steel and hot galvanized steel. In the absence of cold rolling the substrate plating Hong color coated paper, and the production process itself determine the thickness of the substrate and the surface roughness of good uniformity, so no matter which detection method is used, the measurement result of the coating thickness of the substrate than other detection small error. There coating thickness and surface roughness of the substrate determines the fluctuations in the magnetic thickness using the national standard method and the method of making a micrometer thickness of a single point measurement, the measurement results will be severely affected. Because magnetic thickness measurement method for coating the total thickness should first and then measuring coating thickness; and micrometer caitu total thickness measurement method must first Boxing color coated paper, and then measuring the thickness of the substrate were measured twice both methods Operation thickness measurement position can not be ensured at the same point, and therefore will be affected by fluctuations in the substrate and the coating, resulting in fluctuation of measurement results, and the thickness fluctuation measurement result fluctuation is proportional to the substrate.
