Abstract

The invention discloses an electromagnetic pure iron part with a transparent water-soluble protective film. The electromagnetic pure iron part comprises an electromagnetic pure iron part body, whereinthe protective film wraps the outer surface of the electromagnetic pure iron part body and is a nano-thickness protective film. The preparation method of the electromagnetic pure iron part comprisesthe following steps: firstly, mixing higher fatty acid, polyol, organic amine, carboxylate and pure water, and uniformly stirring to obtain a protective solution; and secondly, putting the electromagnetic pure iron part body into the protective solution, completely wetting the surface of the electromagnetic pure iron part body, and naturally drying to obtain a finished product. By use of the electromagnetic pure iron part, the contact of a vacuum arc-extinguishing chamber and air is isolated so as to avoid the oxidation phenomenon; and the cleanness of a surface structure of the electromagnetic pure iron part is kept and existing defects on the surface can be observed with naked eyes.

Description

technical field [0001] The invention belongs to the technical field of iron parts, and in particular relates to an electromagnetic pure iron part with a transparent water-soluble protective film, and also relates to a preparation method of the electromagnetic pure iron part. Background technique [0002] In the prior art, the electromagnetic pure iron parts are magnetic gathering parts or shielding cylinders of the vacuum interrupter, and the raw materials are processed, cleaned, protected with anti-rust oil, packaged, degreased, pickled, and passivated into the final assembly of the vacuum interrupter. Units, assembled and welded in components or complete tubes of vacuum interrupters. But there are following defects in existing electromagnetic pure iron parts: [0003] 1. In order to ensure the oxidation and rust of the electromagnetic pure iron parts used in the vacuum interrupter during packaging, transportation, storage and handling, anti-rust oil is used to isolate the...
