There are many patterns of color-coated steel plate, but different patterns may need different methods and techniques when producing. In order to better understand the method of its formation, let's introduce the specific operation next.
1. Coating method: After solidification of pure zinc liquid, spray water mist (a mixture of water, steam, water and air) on the surface of the color-coated steel sheet to form crystal nuclei. The coagulated zinc solution is the starting point for the spread of spangles.
2. Surface blowing method: When the pure zinc layer of the color-coated steel sheet is about to solidify, using sulfur dioxide gas to flow over the surface, the spangle crystals can grow smoothly and obtain larger patterns. This method can form a dense oxide film and improve the corrosion resistance of the zinc coating. This method can be used for thin galvanized printing color coated sheets. It uses a magnetic roller to bring the wire mesh into contact with the zinc surface to achieve this goal. First, the joints of the steel mesh are cooled, and the solid particles forming the joints first become crystal nuclei. The remaining solidified zinc liquid, the crystal nucleus, begins to expand outward to form spangles. The production of spangles is related to the quality of the finished product. If you need to make a large spangle on the color coated steel plate, you need to consider various factors.
If the color coated steel plate is not allowed by external conditions, the designed product will not be of guaranteed quality, so everyone must pay attention to it in the future.
