The color steel plate has the properties of high mechanical strength and easy forming of steel materials, as well as good decoration and corrosion resistance of coating materials. Steel color plate is an emerging material respected in the world today. Many steel color panels play an important role in rapidly developing industrial cities, but there are often many problems in the production process of steel color panels. Today, let's talk about what problems should be paid attention to when producing steel color panels.
There are wrinkles on the edge of the steel color plate. When there is no problem with the equipment, the original existence of the substrate generally occupies a large proportion. The wrinkles of the hot-dip galvanized steel plate are mainly caused by the existing technology of the galvanizing production line and the failure of the equipment. It is generally understood It is not difficult for friends of galvanizing process to solve this problem. Judging the quality from the appearance of the steel coil: Generally speaking, the appearance requires neat winding, and there are no burrs, serrated edges, and obvious gaps on both sides of the steel coil. diverse issues.
The lines of the steel color plate are not smooth, and the paint or back paint after the product comes out has the phenomenon of paint leakage, which is called in the industry: lines. This kind of problem is generally an unavoidable problem for every manufacturer. There is a part of impurities in the paint, part of the reason for the equipment, and a proportion of the factor of the substrate.
The color difference on the surface of the steel color plate is partly related to the quality of the paint. There are also practical problems in the production process. The type of substrate also occupies a certain proportion. The steel color plate produced by the process and raw materials will appear different.
There are holes and missing coating on the surface of the steel color plate, because the quality of the substrate is defective. If the substrate has serious edge damage and gaps, and there are holes in the substrate, the painting staff will open the painting equipment according to the industry standard operation requirements and let it skip. , it is inevitable that there will be leakage phenomenon.
There is a bulging phenomenon on the wave edge or the middle of the steel color plate: the main reason is the quality problem of the substrate. The predecessor of the substrate is rolling hard, and the wave edge phenomenon caused by uneven thickness is the most, and the other is less due to equipment problems. This is the actual reason. If the substrate is not waved and painted, the general situation is: It is caused by the abnormal operation of deviation correction or other equipment.
The paint peeling off the surface of the steel color plate: the production unit should check the pressure and whether the equipment operation system is normal and good, whether the bearing is working well, and 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 scratches on the dry film of the paint on the steel color plate. It is recommended that customers pay attention to such problems. The quality of the paint is the most important thing that depends on the quality of the product. The weather resistance, flexibility and hardness of the paint film are proportional to the inspection results of the product, which means that the quality of the paint is qualified, such as: impact and wipe resistance. Both T-bend and T-bend can reflect the actual quality problems of the paint. If there is a substandard operation within the scope of the process flow, the cause must be immediately found and substantive adjustments should be made.
