Dual-phase-state wiping type stainless steel rust removal friction plate

The invention discloses a dual-phase-state wiping type stainless steel rust removal friction plate, and belongs to the technical field of stainless steel processing. According to the dual-phase-statewiping type stainless steel rust removal friction plate, water is sprinkled on a rusted area, then a pickling friction plate is placed on the rusted area and rubs with the rusted area repeatedly, anda pre-protective layer is in contact with the water and is dissolved, so that a reaction powder layer in the pre-protective layer reacts with the air to release a lot of heat while generating ferroferric oxide powder. On one hand, by means of increase of the heat, a fixed magnetic variation ball can have magnetism and attract the ferroferric oxide powder, so that a U-shaped elastic rope is bent, and the wiping effect of the U-shaped elastic rope and supporting short thorns on the rusted area can be improved; and on the other hand, air in a phase change air bag can be extruded out through extrusion of the supporting sho
