Caitu amount is very large, how to choose a good color coating it, following Xiaobian to introduce the choice of what kind of color-coated according to use and they Boxing color coated paper, the correct choice of drugs by practical experience, it is recommended to try the test, in order to avoid too much material selection, resulting in economic performance of less than one thousand expected to not meet the requirements. Selection of materials in general from the following considerations. 1. Select the color-coated substrate, substrate type: cold rolled sheet, galvanized plate, alloyed galvanized plate, hot galvanized plate, cold rolled galvanized sheet A. substrate: high corrosion resistance is not available for the production of household appliances internal components. B. galvanized substrate: good corrosion resistance, corrosion resistance and therefore high demand products, such as building use, roofs, walls, hangars, grain, etc. must use this color coated steel. C. For color coated coil prices special requirements, such as requiring better stamping, drawing and other properties of the product, you need to consider the choice of the appropriate level of deep drawing board. 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 smaller, and therefore more affected by human factors using small impact 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 magnetic thickness measurement, French micrometer thickness difference measurement, drilling destructive microscopic observation are wedge-cut method, optical microscopy test method for arbitration. Weighing method is very tedious color coated paper, discomfort plant laboratory for the fast-paced; X-ray fluorescence and β-ray reflection method is by measuring certain characteristics of the coating element content to calculate the coating thickness, for color Such coating formulations not coated plate 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 Coating thickness and the total thickness of the coating, the coating thickness is calculated. 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.
