Example Embodiment

[0024] Example

[0025] Use a sander to grind the edges and corners of the corrugated beam and plate components of the expressway, and grind their right angles into obtuse angles or arcs;

[0026] The above workpieces are shot blasted by a shot blasting machine. The number of blasting heads is 8, the line speed is 1.5m / s, and the abrasive is 1-2mm of steel wire. Air blows away dust and impurities on the surface;

[0027] The workpiece after rough blasting is then shot blasted. The number of shot blasting machines is 8, the line speed is 1m / s, and the abrasive is 2-4mm. The surface cleanliness and roughness reach the Sa2.5 level required by GB8923. The above requirements, and then use compressed air to blow off the dust impurities on the surface;

[0028] Use a high-speed arc spray gun to spray zinc on the edges and corners of the corrugated beam plate and its surrounding area of ​​5-10mm, and the thickness of the zinc layer is 40-50μm;

[0029] Hang the zinc-sprayed workpie...

Abstract

The invention discloses a zinc-based heavy-duty corrosion prevention protecting process of a steel structural component, which belongs to the metal coating protecting technology field. The invention has the following process flows: the rim angle position burnishing of the steel structural component, the first impact cleaning, the second impact cleaning, the rim angle hot spraying, the bottom powder spray, the agglomerating semi-solidification, the surface powder spraying, the solidification, and the cooling and packaging. The invention has the advantages that through the zinc-based heavy-duty corrosion prevention compound coating technology processing to the steel structural component, the protecting effect is prominent, and the application value is good.

Description

technical field [0001] The invention relates to a coating protection technology for steel components, in particular to a zinc-based heavy-duty anti-corrosion protection technology for steel components, and belongs to the technical field of metal coating protection. Background technique [0002] Due to long-term exposure to the atmosphere, the steel components undergo chemical and electrochemical reactions due to climate change, sunlight, rain, moisture and corrosive media contained in the atmosphere, and the surface is rapidly oxidized, resulting in material performance degradation or even failure. [0003] Coating protection technology is commonly used, cost-effective, and can be divided into two categories: non-metallic coatings and metal coatings. Non-metallic coatings include paint coatings, powder coating coatings, and inorganic material covering coatings. They mainly use shielding methods to block the contact between the corrosive medium and the...
