Rusting prevention method based on surface rust removing of figured steel structure

Abstract

The invention relates to the technical field of steel structure treatment and particularly relates to a rusting prevention method based on surface rust removing of a figured steel structure. The rusting prevention method comprises the steps of surface dust treatment, side surface impurity treatment, bottom surface impurity treatment, top surface impurity treatment, integral rust removal, high-pressure washing, pre-heat drying, bottom layer rust removing, middle layer rust prevention and outer layer spraying with corrosion protection paint. A figured steel surface treatment device is further related. The figured steel surface treatment device comprises a conveying mechanism and a grinding cleaning mechanism. According to the rusting prevention method, all-round grinding cleaning can be completed in the conveying process of I-steel, the cleaning efficiency can be greatly improved, and the problems that omission exists in the polishing process of a hand mill, and surface treatment is uneven are fundamentally solved; by arranging multiple rusting prevention layers and additionally arranging a waterproof binding layer in the rusting prevention layers and through polishing after immobilization, even and compact rust prevention layers can be formed, surface pores can be reduced, and the phenomena such as peeling, bulging and the like in the late stage of usage can be effectively prevented.

Description

Technical field [0001] The invention belongs to the technical field of steel structure treatment, in particular to an anti-rust method based on the surface rust removal of special-shaped steel structures. technical background [0002] Steel structures are widely used in building construction, factory building, supporting and fixing of large boilers, etc. because of their high material strength, light weight and high structural reliability. According to the cross-section shape of steel structures, they can be divided into simple cross-section steel structures (such as square steel, round steel and angle steel) and complex cross-section steel structures (such as I-beam, bent steel and channel steel). Among them, I-beam is widely used in factory buildings, supports, foundation piles and so on, and its cross-section is H-shaped. [0003] When I-beams are stacked in the open air after production, it is easy to cause rust oxidation, which will lead to the corrosion of steel structures ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a method for preventing rust based on special-shaped steel structure surface rust removal. The method proposed in the present invention also specifically relates to a special-shaped steel structure surface treatment device, mainly for industrial The surface impurities of the beam are treated, and all-round grinding and cleaning can be completed during the transmission of the I-beam. It does not need to be turned over and cleaned repeatedly, and the cleaning efficiency can be improved. It also fundamentally solves the problem of omissions and For the problem of uneven surface treatment, by setting up a multi-layer anti-rust layer, adding a waterproof adhesive layer to the anti-rust layer, and then grinding after immobilization, it can form a uniform and dense anti-rust layer, reducing the surface The existence of pores can effectively prevent the phenomenon of peeling and bulging of the anti-rust layer in the later period of use
