1. Use oxidant-free impregnating varnish, moisture-proof measures for riveting machine parts such as epoxy polyurethane or unmodified epoxy impregnating paint. Use paints that do not contain volatile acids. Vibrating machinery should use solvent-free paint whenever possible.
2. When the varnish is impregnated with melamine acid, the curing temperature and curing time should be adjusted, the curing temperature should be slightly higher than 130C (for example, 135C), and the curing time should be more than 180 minutes, and the process must be strictly implemented.
3. Various methods are used to apply a maintenance layer on the metal surface to isolate the metal from the corrosive environment, to inhibit the corrosion process or to reduce the contact between the corrosive medium and the metal surface, so as to avoid or reduce the purpose of corrosion.
