Process for preventing corrosion of wet and rusted coating steel structure

Abstract

The invention relates to the technical field of steel structure treatment, in particular to a process for preventing corrosion of a wet and rusted coating steel structure. The process comprises the steps of step 1, steel structure rust removal, step 2, steel structure cleaning, step 3, environment-friendly graphene metal rusted corrosion prevention coating preparation, step 4, steel structure coating and step 5, paint coating quality inspection and acceptance inspection. The whole recoating work time is short, the safety risk is small, rust removal and coating are fast, the recoating quality is good, the service life is long, the total manufacturing cost of the whole recoating project is not higher than that of common paint, the service life is at least doubled, the whole recoating process is environmentally friendly, no harm is caused to the environment and the human body, the standard requirement for steel structure surface treatment and the influence of environment humidity and temperature on coating work are reduced, the technology is simple, operation is convenient and fast, the working efficiency of the anti-corrosion technology is effectively improved, and the working time is shortened.

Description

technical field [0001] The invention relates to the technical field of steel structure treatment, in particular to a process for anticorrosion of steel structures coated with wet rust. Background technique [0002] Corrosion is a kind of destructive erosion caused by chemical or electrochemical reaction between metal and surrounding environment, which is a ubiquitous natural phenomenon. It lurks around us, turning precious materials into waste, causing premature scrapping of production and living facilities, and causing heavy losses to the national economy and personal property. Corrosion causes weakening and deterioration of steel structure sections in railway systems, breakage of bridge bracket railings, premature failure of supports, failure and fracture of fasteners, etc. The corrosion of steel structures in coastal areas, southern humid areas, acidic soils, and areas where acid rain is concentrated is more like a shadow, and it is getting worse. It is an urgent need t...
