The invention discloses a steel structure rust prevention process, which comprises the following steps: (1) surface treatment: removing rust, oxide skin and old paint film attachments which are not firmly attached on the surface of the metal by using a steel wire brush, a scraper knife, abrasive paper and a grinding wheel net; (2) preparing a coating: before the coating is prepared, the coating is stirred uniformly, and can be used after the crust or other impurities are removed; fully and uniformly stirring the prepared coating, and performing trial coating; (3) the coating method comprises the following steps: the coating method adopts a method of combining mechanical spraying and brushing coating for construction, mechanical spraying is adopted for large-area construction, and brushing is adopted for small components; (4) and (5) coating. The construction process is simple, and the steel structure is rust-resistant and fireproof, so that the strength of the steel structure is ensured, the personal safety and the equipment safety are protected, the service life of the steel structure is prolonged, and the economic investment is reduced. |
