1: The edge of the color steel plate product is wavy or loose in the middle: the main problem is the quality of the substrate. The precursor of the base plate is rolled. Due to the uneven thickness, there are many wave edges, and there are few other equipment problems. This is the actual reason. If the base plate is not painted with wave edges, it is generally: correct or other equipment operation is abnormal.
2: Line: After the color steel plate product comes out, the finish or back paint leaks, which is called line in the industry. Generally speaking, it is difficult for every manufacturer to avoid such problems. There are impurities, equipment reasons and substrate factors in the paint.
3. Wrinkles of Jinan color steel plate products: When the equipment has no problems, the original existence of the base material usually accounts for a large proportion. The wrinkles of hot-dip galvanized steel sheet are mainly caused by the technical and equipment failures of the galvanizing production line. Generally speaking, 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, the appearance is required to be neat, there is no burr and serrated edge on both sides of the steel coil, and the gap on both sides is obvious. This is at least the requirement, but it is difficult to judge various problems encountered in production.
5: Hole, coating leakage: due to the quality defect of the substrate, if the substrate has serious edge damage and gap, and the substrate has holes, the paint personnel will open the paint equipment according to the operation requirements of the industry specification to skip, and there is inevitably coating leakage.
6: Tile mark paint peeling: the production unit should check the pressure size, whether the equipment operation system is normal and good, whether the bearings work well, whether the pressing action of each group of steel rollers is consistent, and the actual interference problem. Due to the sharpness of the press wheel, the new press equipment is easy to cause dry film scratches on the color steel plate paint. We recommend that customers pay attention to such problems.
7: Paint quality: paint quality is the key to product quality. The weatherability, flexibility and film hardness of the paint are in direct proportion to the product inspection results, indicating that the paint quality is qualified. For example, impact resistance, wipe resistance and T bending can reflect the actual quality problems of the paint. If the operation within the process scope is not up to the standard, it is necessary to immediately find out the causes and make substantive work adjustments.
8: Color difference: paint quality is a part of the production process, and there are also practical problems. The type of substrate also accounts for a certain proportion. The color difference of galvanized steel plate, aluminum-zinc steel plate, color steel plate produced by the same process and raw materials will be different, which has a great relationship with the type of substrate. Therefore, users are advised to pay attention to such problems in production.
9: Zinc particles: due to the original problem caused by quality defects, the color steel plate substrate is generally not suitable for computer production, and the quality inspector has the right to decide whether to produce.
10: Blistering: the color steel plate substrate reacts with the core material.
These 10 quality phenomena of color steel plate must be avoided, otherwise it is very easy to cause the low quality of color steel plate project. More relevant product content is available on our website http://www.jnjgcg.com Ask!
