Problems solved by technology

[0002] Most of the existing electric pole galvanizing processes have unreasonable process settings, unreasonable process parameters, and high requirements for operator experience, resulting in high production costs, low product quality, and low yield
In addition, the connection parts of the power poles are all connected by bolts. If the connection parts are galvanized, the friction surface of the contact surface will be greatly reduced, which will cause the connection parts to loosen with the increase of time and load, and eventually appear Security risks

Abstract

The invention relates to an improved galvanization process for a power pole. The improved galvanization process for the electric pole comprises the following steps of (1) carrying out acid pickling and phosphating on the power pole; (2) firing the power pole; (3) polishing the power pole; (4) soaking the power pole in a plating assistant agent; (5) carrying out hot galvanizing on the power pole; (6) carrying out air blowing on the galvanized power pole; (7) putting the power pole subjected to air blowing into a clear water cooling pool for cooling; (8) passivating the cooled power pole; and (9) carrying out anti-friction treatment on the passivated power pole by using an anti-friction treatment agent. According to the the improved galvanization process for the electric pole provided by theinvention, the process is reasonable, the manufacturing cost is low, the product quality is high, and the friction coefficient is effectively increased.
