Steel structure antirust process

Abstract

The invention discloses a steel structure antirust process. The antirust process includes the following steps of firstly, surface treatment, wherein rust, oxide skin and infirmly-attached old paint film attachments on a metal surface are removed through a wire brush, a scraper knife, abrasive paper and grinding wheel mesh; secondly, preparation of paint, wherein before the paint is prepared, uniform stirring should be performed, use cannot be performed until crust or other debris is removed, and the prepared paint needs to be sufficiently and uniformly stirred and applied on trial; thirdly, the coating method of the paint, wherein the mechanical spraying and brushing combined method is applied for the implementation of the coating method, mechanical spraying is adopted for large components, and brushing is adopted for small components; and fourthly, coating of the paint. The implementation process is simple, a steel structure is resistant to rust and fire, the strength of the steel structure is ensured, personal and equipment safety is protected, the service life of the steel structure is prolonged, and economic investment is reduced.

Description

technical field [0001] The invention relates to the field of antirust construction, in particular to a steel structure antirust process. Background technique [0002] As the main form of modern architecture, steel structure has the advantages of light weight, high strength, good seismic performance, short construction period, high degree of industrialization of construction, and large space utilization rate at room temperature. However, the characteristics of poor fire resistance of steel structure buildings are also very obvious, because although steel is a non-combustible material, it is a good conductor of heat and can easily conduct heat. After the temperature of steel exceeds 300 degrees, the yield point and ultimate strength drop significantly, and the strength is almost equal to zero when it reaches 600 degrees. In the event of a fire, the unprotected steel structure will heat up to over 540 degrees in just 15 minutes, causing distortion and deformation of the compon...

Problems solved by technology

In the event of a fire, the unprotected steel structure will heat up to over 540 degrees in just 15 minutes, causing distortion and deformation of the component itself, leading to collapse and destruction of the building, and the deformed steel structure cannot be repaired.
