In order to remove the substrate surface when the wrong color coated cleaning, Intuit points or adversely affect product quality conversion film, as a subsequent step to provide a clean surface, so as to improve the adhesion and corrosion resistance of products between the substrate and the paint laid foundation. Practice and research results show that the quality of color-coated depends primarily on cleaning and chemical pretreatment that conversion process, so use color coated paper, cleaning work is an important part of ensuring the quality of color-coated. Many factors affect the quality of cleaning, but can be summarized in the main not cleaning equipment, cleaning agents and cleaning process in three aspects. Only reasonable control these three factors to achieve the desired cleaning effect. Color coated steel substrate a cold rolled coil, galvanized sheet, galvanized plate and galvanized aluminum panels, although their surface conditions vary, but the basic cleaning process is similar to the main process: pre-cleaning - washing - wash - a multi-stage washing - dry. Color-coated substrates typically include cold rolled steel, galvanized steel, galvanized steel and hot galvanized steel. In the absence of cold-rolled substrate coated lime color coated paper, and the production process determines the thickness and surface roughness of the substrate itself uniformity better color coated paper, so no matter what color coated paper using detection methods Hongji, its coating thickness measurement results of detection than other substrates 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 gauge must first determination method for coating total thickness, thickness of the coating was measured; and micrometer measurement method must first color coating total thickness, thickness of the substrate was measured again, two of the two methods were unable to ensure that the thickness measuring operation a measurement position at the same point, so are affected by fluctuations of the substrate and the coating, resulting in fluctuations in the measurement results, and the results of the thickness measurement is proportional to the fluctuation of the fluctuation and the substrate.
