Steel structure surface curing film

Abstract

The invention discloses a steel structure surface curing film, and belongs to the technical field of steel structure protection. The steel structure surface curing film comprises a solid state outer end release film and a single water permeable composite fiber film, wherein the solid state outer end release film and the single water permeable composite fiber film are fixedly connected; a film damage restoration ball and a water suction composite fiber resin ball are arranged between the solid state outer end release film and the single water permeable composite fiber film; the film damage restoration balls are uniformly distributed in the solid state outer end release film and the single water permeable composite fiber film; an additional protection layer for the easy-to-corrode steel structure near the port can be realized; a water film formed on the surface of the steel material is blocked, so that the steel structure electrochemical corrosion conditions cannot form; meanwhile, through the special curing film installing device, the damage position of the curing film can be fast repaired; the influence on the use of the steel structure buildings of the steel structure anti-rust curing stage can be reduced.

Description

technical field [0001] The invention relates to the technical field of steel structure protection, in particular to a steel structure surface maintenance film. Background technique [0002] Steel structure is a structure composed of steel materials. It is one of the main types of building structures. Chemical, washing and drying, galvanizing and other rust removal and antirust processes, the components or parts are usually connected by welds, bolts or rivets, because of their light weight and easy construction, they are widely used in large factories, venues, super In high-rise and other fields, steel is characterized by high strength, light weight, good overall rigidity, and strong deformation ability, so it is especially suitable for building large-span, ultra-high, and ultra-heavy buildings; material homogeneity and isotropy are good, It is an ideal elastic body, which is most in line with the basic assumptions of general engineering mechanics; the material has good plas...

Problems solved by technology

[0003] When the existing steel structures used in some buildings are used in the normal temperature atmosphere, the steel is corroded by the action of moisture, oxygen and other pollutants in the atmosphere, such as uncleaned welding slag, rust layer, surface dirt, etc. , especially when the relative humidity of the atmosphere increases to the critical humidity value, the corrosion rate of steel suddenly increases. In the environment of humid and corrosive media, the corrosion reaction is very serious. When the air is polluted or the air in coastal areas contains salt, The critical humidity is very low, and the water film is easy to form on the surface of the steel. At this time, the welding slag and the untreated rust layer (iron oxide scale) are used as the cathode, and the steel structural member (base material) is used as the anode to undergo electrochemical corrosion in the water film. After the steel structure has a corrosion reaction, it will not only cause safety hazards in the steel structure at the corrosion point, but also affect the safety of the entire steel structure building.
