A method of anti-corrosion treatment of the threaded rod rudder

The present invention belongs to the technical field of electrostatic powder coating corrosion in the marine environment, to a method of anti-corrosion treatment of the threaded rod rudder; first selecting rudder externally threaded rod, trapezoidal cross section or a rectangular configuration tooth structure, then the link square edges chamfered thread, its surface to be painted and then cleaned and dried after grounding screw rod, a first channel and silk thread covered with transparent tape to the threaded rod after the electrostatic spraying of the powder, the threaded rod was placed in an oven heated cooling after baking, sintering and heat curing is completed, the final cut off excess car PEEK layer, a first channel of the threaded rod to the secondary yarn is heat sintered powder and electrostatic spraying and curing, complete the overall link thread insulated preservatives; overall process principle reliable, simple and easy to control steps, using readily available equipment, spray powder good preservative effect, long life, environmentally friendly corrosion.
