Embodiment Construction

[0017] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0018] According to an embodiment of the present invention, a method for surface treatment of a steel structure part is provided.

[0019] The surface treatment method of the steel structure parts of the present embodiment mainly includes:

[0020] a. Use a liquid sandblasting machine to perform a sandblasting treatment on the outer surface of the steel structure parts to remove scale, rust and oil stains, which is beneficial to the impact of high-speed sand flow to clean and roughen the surface of the substrate;

[0021] A sandblasting operation, specifically including:

[0022] Compressed air is used as the power to form a high-speed jet beam to spray the spray material containing copper ore, quartz sand, corund...

Abstract

The invention discloses a surface treatment method for steel-structure parts. The method mainly includes steps: using a wet sand-blasting machine for primary sand blasting treatment of outer surfaces, with scales, rusts and oil stains removed, of the steel-structure parts, and cleaning and roughening the surfaces under the impact action of high-speed sand flow; after primary sand blasting treatment is finished, using cured epoxy zinc-rich paint for secondary spraying treatment; after secondary spraying treatment is finished, using varnish for tertiary varnishing, and finishing the surface treatment after natural drying is performed. The surface treatment method for the steel-structure parts overcomes defects of poor corrosion resistance, high cost, poor environment friendliness and the like in the prior art and has the advantages of excellent corrosion resistance, low cost and high environment friendliness.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to a method for surface treatment of steel structure parts. Background technique [0002] Steel structural parts are generally made of iron, which is prone to rust when exposed to water or moisture. For example, the steel structure casing is composed of an outer casing and an inner casing. The outer casing is welded by a cylinder and a stiffener plate. The outer circle of the inner casing is processed with a water tank along the circumferential direction. The casing material is carbon steel. , During the use and storage of the steel structure, the cooling water is easy to corrode the casing and cause rust, and the rust flocs block the water inlet and outlet pipes, resulting in the steel structure not working properly. [0003] So far, steel structure parts at home and abroad have not been surface treated, but special cooling fluid is used, but the cost is relatively high. ...
