Caitu test: 1, does not allow a clear pores, bubbles, stack flow and wrinkling. 2, does not allow the existence of pitting, impurities, scratches, dirty and uneven surface coating. 3, does not allow a serious drain coating, coating off, blending, adhesions. Baking is not allowed due to excess coating crisp yellow, loss of light and so on. 4, do not allow the existence of a clear color or gloss uneven. More use of domestic high detection accuracy and faster method micrometer coating thickness as the detection method of color-coated. While abroad due to less volatile substrate measured fluctuations DJH law also painted a smaller volume of Shandong prices, so more use of small impact by human factors DJH law. International and domestic other international and national methods for coating thickness measurement methods include other wedge-cut method, the thickness difference measurement, weighing, X-ray fluorescence method, β-ray reflection method, measuring the magnetic and eddy current measurement method. Caitu GB in the case of magnetic measurements of magnetic gauge prepainted coil, French micrometer thickness difference measurement Binzhou color coated paper, drill-destructive microscopic observation are wedge-cut method, optical microscopy method for arbitration test methods. Weighing method is very complicated, does not apply to factory laboratory for fast-paced; X-ray fluorescence and β-ray reflection method is by measuring the characteristics of the coating element content of a coating thickness is calculated, which for color-coated seed coating formulation is not fixed samples is not applicable. Eddy current measuring method in the research and testing operations, found that the current coating thickness measurement caitu most accurate and most simple is a way to combine magnetic and eddy current measurement measurement equipment, measured at the same time through a combination of probe The total thickness of the coating thickness and coating thickness Shandong Boxing color coated paper, the calculated thickness of the coating. This measurement method is due to the same point of measurement for coating thickness and the total thickness of the coating, thus avoiding the magnetic thickness of the coating by the method of the fluctuations, the accuracy of measurement results has been markedly improved.
