Color Coated Aluminum Coil Manufacturers Introduce The corrosion resistance of most Metal Composite Panels requires good corrosion resistance, such as Class I and Class II tableware, kitchenware, water heaters, water dispensers, etc.

Some foreign merchants also conduct corrosion resistance tests on the products: heating with NaCl aqueous solution to boiling, After a period of time, the stainless steel composite material was poured out of the solution, washed and dried, and the weight loss was weighed to determine the degree of corrosion (Note: When the product is polished, the Fe content in the abrasive cloth or sandpaper will cause rust spots on the surface during the test).

In today's society, stainless steel composite materials are generally polished during production, and only a few products such as water heaters and water dispenser liners do not need polishing. Therefore, the stainless steel composite material requires a good polishing performance of the raw material. The main factors affecting the polishing performance of Metal Composite Panel are as follows:

① surface defects of raw materials. Such as scratches, pitting, pickling, etc.

②The problem of raw materials. If the hardness is too low, it will not be easy to polish when polishing (the BQ property is not good), and if the hardness is too low, the orange peel phenomenon is easy appear on the surface during deep drawing, thus affecting the BQ property. High hardness The BQ performance is relatively good.

③ For the deep-drawn product, small black spots and RIDGING will appear on the surface of the area with a large amount of deformation, thus affecting the BQ performance.

Through the above introduction, Galvanized Steel Composite Panel Manufacturers hopes that you can simply refer to the content of this article in future use.
