[0002] Fusible polytetrafluoroethylene (PTFE) anti-corrosion layer is a high-performance anti-corrosion coating. It is made by evenly covering the surface of the substrate with a polytetrafluoroethylene solution by spraying or coating, and then curing it by heating and drying. Polytetrafluoroethylene is highly chemically inert and can resist corrosion from various chemicals, including strong acids, strong alkalis and various organic solvents. This characteristic makes the fusible polytetrafluoroethylene anti-corrosion layer perform well in corrosive environments and can protect the substrate from corrosion damage.
[0003] The commonly used spraying device only sprays the solution on the surface of the substrate. The structure is relatively simple, which easily leads to the solution not being sprayed evenly on the surface of the substrate, thereby easily reducing the anti-corrosion ability of the substrate.
