Abstract

The invention discloses a steel structure anticorrosion construction process, which comprises the following steps: (1) cleaning the surface of the steel structure; (2) coating an environmentally friendly water-based anticorrosion paint. The steel structure anticorrosion construction process of the present invention, the coating film of the environmental protection water-based anticorrosion coating developed has good adhesion to metal, small structural pores, compact structure, excellent adhesion, high impact resistance, good flexibility, and strong corrosion resistance. It has an efficient protective effect on the base metal; all raw materials used in the method are environmentally friendly and pollution-free, which reduces the treatment cost of waste water and waste. On the basis of ensuring the corrosion resistance of metal components, it is energy-saving and environmentally friendly. It is a green and environmentally friendly metal anti-corrosion Rust removal method.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion construction, and in particular relates to a steel structure anti-corrosion construction technology. Background technique [0002] Steel is an indispensable material in modern social and economic life, and is widely used in industrial and agricultural production and people's lives. Steel structure is a young and very vigorous steel structure system, which has been widely used in general industrial and agricultural, commercial, and service buildings, such as office buildings, villas, warehouses, stadiums, entertainment, tourist buildings, and low and multi-storey residences construction and other fields. As the main form of modern architecture, steel structure is widely used because of its light weight, high strength, good seismic performance, short construction period, high degree of industrialization of construction, high space utilization rate, and investment saving. [0003] However, t...
