There are many ways to prevent corrosion of metal mesh belts, mainly including improving the properties of the metal itself, separating the metal to be protected from corrosive agents, treating the surface of the metal mesh belt, improving the corrosive environment, and employing electrochemical protection methods. Covering the surface of metal mesh belts with various protective layers to separate the metal from corrosive substances is an effective way to prevent corrosion; among these, oxidation treatment, phosphating treatment, non-metallic coatings, and metal platings are the more common methods. A phosphating film is a non-metallic, non-conductive, porous chemical conversion coating that can suppress the formation of corrosion microcells on the metal surface, thereby effectively preventing corrosion and enhancing the corrosion resistance and adhesion of the coating. As the positive ions from the metal mesh belt become hydrated and enter the solution, excess electrons accumulate on the surface of the metal mesh belt, causing it to become negatively charged. Meanwhile, the hydrated ions entering the solution make the liquid layer adjacent to the metal surface positively charged; this creates a double layer at the interface between the metal mesh belt and the solution. After the double layer is formed, due to the electrostatic attraction, the excess electrons on the metal mesh attract the hydrated cations in the solution toward the metal mesh. This process occurs in the opposite direction to the charge transfer in the previous process. When the rates of these two processes are equal, a state of charge equilibrium is established. When the coating area of the metal mesh belt is kept constant, it can be seen that there is an inverse correlation between Cd and the distance between the electrode plates (which can be understood as the distance between the metal substrate and the coating). Therefore, to enhance the adhesion of the organic coating to the metal mesh substrate, the thickness of the interfacial transition layer can be reduced (to the nanometer level). The silanization process using metal mesh belts is harmless to humans and does not pollute the environment; the treatment solution can even be discharged directly. However, since silanes are unstable in aqueous solutions, it is very difficult to master this skill accurately; only a very limited number of manufacturers possess this capability, and there are significant differences in their skill levels. Through years of development, silane technology has overcome the inherent shortcomings of zinc-based phosphating processes, and it now boasts a high level of industrial applicability, capable of meeting the requirements of industries such as hardware, automotive, and home appliances. The silane process can be applied to existing phosphating production lines; it can be put into operation by simply adding a pure water system, without the need for any other equipment modifications. As a pre-treatment technique for nanoscale metal mesh belts, silane treatment contains no phosphorus or any harmful metal ions, and it enables the simultaneous treatment of various metal substrates. It provides excellent coating adhesion and corrosion resistance, and is gradually replacing traditional phosphating pre-treatment processes. A nanoceramic chemically converted film with a dense structure is deposited on the surface of the metal mesh belt substrate; it possesses strong barrier properties and good adhesion to the oxides present on the metal mesh belt as well as to any subsequent organic coatings. This improves the corrosion resistance of the coating on the metal mesh belt significantly, thereby extending its service life against corrosion.
