Wear of the drive components in coating machine fans is a common issue with general equipment, such as wear at bearing locations, bearing housings, and bearing areas on the fan shaft. Considering these typical coating machine fan failures, traditional maintenance methods include surface treatments, thermal spraying, and polishing; however, each of these approaches has certain drawbacks.

High-temperature welding cannot completely eliminate thermal stress, making it prone to material damage, component bending, and breakage. Electroplating with brushes is limited by coating thickness and easily peels off. The above two methods do not allow metal-to-metal repair, failing to change the "hard-on-hard" matching relationship. Under the combined effects of various forces, the adhesive roller will wear again.

To address the aforementioned issues, most Western countries have adopted polymer composite repair methods that eliminate welding-induced thermal stress and impose no restrictions on repair thickness. At the same time, the metal materials used in these products do not compromise structural integrity, effectively absorbing equipment impacts and vibrations to prevent further wear, gradually replacing traditional coating machine fan failure repair practices in China.
