Anti-friction treatment process of joint surface of steel structure after galvanizing

Abstract

The invention relates to an anti-friction processing process for a connection face after galvanization of a steel structure. The process comprises the steps of galvanization processing, preparation ofanti-friction processing agents, polishing of a connection beam and a connection board of the galvanized steel structure, and transverse brushing and longitudinal brushing of the steel portion needing to be brushed. A zinc layer on the surface of the steel is not damaged, and the friction coefficient is increased at the same time.

Description

technical field

[0001] The invention relates to an anti-friction treatment process for a steel structure, in particular to an anti-friction treatment process for a galvanized steel structure. Background technique

[0002] In today's society, there are many projects using steel structure materials in the construction of thermal power plants or in the construction of thermal power plants. However, in order to increase the service life of steel structures, it is necessary to carry out anti-corrosion treatment on steel structures. At present, the anticorrosion of steel in the world adopts hot-dip galvanizing. After the steel structure products are hot-dip galvanized, the connection parts of the steel structure steel beams are connected by bolts. The friction surface of the surface will be greatly reduced, so that the connection parts of the steel structure will loosen with the increase of time and load, and eventually there will be safety hazards.
