1: The phenomenon of wavy edges or loose belly in color steel plate products: it is mainly the quality problem of the substrate. There are more wavy edges caused by uneven thickness, and less other equipment problems. This is the actual reason. If the base plate is not painted with wavy edges, the general situation is: deviation correction or other abnormal operation of equipment.
2: Line: after the color steel plate products come out, there is paint leakage in the finish or back paint, which is called line in the industry. Such problems are generally unavoidable for every manufacturer. There are impurities in the paint, equipment and substrate.
3: Folding of color steel plate products: when there is no problem with the equipment, the original existence of the base plate generally accounts for a large proportion. The folding of hot-dip galvanized steel plate is mainly caused by the existing technology of the galvanizing production line and the failure of the equipment. Generally, it is not difficult for friends who know the galvanizing process to solve this problem.
4: Judging the quality from the appearance of the steel coil: Generally speaking, the appearance requires that the coil be wound neatly, and there are no burrs, jagged edges and obvious gaps on both sides of the steel coil. This is the minimum requirement, but it is difficult to judge the various problems encountered in production by these alone.
5: Holes and missed coating: due to the quality defects of the base plate, if the base plate has serious edge damage, gaps, and holes in the base plate, the painting staff will open the painting equipment according to the operation requirements of the industry specifications and let it skip, which will inevitably lead to the phenomenon of missed coating.
6: The paint peeling of the tile marks: the production unit should detect the pressure, whether the equipment operation system is normal and good, whether the bearings work well, and then whether the pressing action of each group of steel rollers of the tile press is consistent, there will be actual interference problems. Due to the sharpness of the pressing wheel of the new press equipment, it is easy to cause dry film scratches on the paint of color steel plate. It is recommended that customers pay attention to such problems.
7: Paint quality: paint quality is the top priority of the key to product quality. The weatherability, flexibility and hardness of the paint film are directly proportional to the inspection results of the product, which means that the quality of the paint is qualified. For example, impact, wipe resistance and T-bend can reflect the actual quality problems of the paint. If there is a non-standard operation within the scope of the process flow, we must immediately find the cause and make substantive work adjustment.
8: Color difference: the quality of paint is related to one part, and there are practical problems in the production process. The type of substrate also accounts for a certain proportion. Different color differences exist in galvanized steel plate, aluminized zinc steel plate, color steel plate produced by the same process and raw materials, which is closely related to the type of substrate. Therefore, users are advised to pay attention to such problems in production.
9: Zinc particles: the original problems caused by the quality defects of the color steel plate substrate. Generally, such a substrate is not suitable for machine production, and the quality inspector has the right to deal with it and decide whether to produce it.
10: Blistering: Jinan color steel plate substrate and core material have chemical reaction.
