Zincium base heavy corrosion protection technique of environment protection type steel component

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...

Problems solved by technology

[0006] Due to the unavoidable contact or even collision of steel components with other objects during storage, transportation, installation or use after painting, it is very easy to cause damage to the coating on edges, corners and welds, forming corrosion breakthrough points and affecting decoration. Not to mention the effect, what is more serious is the hidden danger of corrosion. After many components are damaged, it is difficult to ensure timely repair, which leads to the spread of corrosion and damage.
