steel structure has a higher degree of mechanization in its manufacturing and installation, and can achieve complete sealing after welding. It is currently widely used in factory manufacturing and building components. The most important thing is that after the steel structure building is demolished, it will not produce construction waste and can be recycled and reused. However, steel structures have poor corrosion resistance and are prone to rust and oxidation. The corrosion scope of steel structures generally includes: large steel structures such as lightning rods iron towers, offshore lighthouses, large reservoirs gates, water supply towers, offshore oil production facilities, tankers, spherical tanks, storage tanks, oil tanks, carbonization towers, heat exchangers, Chimneys, containers, ship hulls, offshore platform steel structures, etc., are mostly exposed to the corrosive environment of marine atmosphere and industrial atmosphere for a long time. Next, follow the editor to understand what phenomena will occur if the limited steel structure rusts and what hazards will it cause? What should we do about this?
1. The rust phenomenon of steel structures can be divided into three types:
① Mild rust: pitting corrosion occurs on the surface, and oxide scale appears on some parts.
② Moderate rust: The red rust spots are obvious and some of the oxide scales are cracked.
③ Severe rust: The oxide scale peels off, and there will be a protruding oxide layer. Some thick oxide layers cause depressions on the surface of the steel structure.
2. Three major hazards caused by rust of steel structures:
① Rust of steel structures will lead to a reduction in bearing capacity and affect structural stability.
② Rusting of the steel structure will lead to increased maintenance costs.
③ Rusting of the steel structure will shorten the service life.
If the rust of the steel structure is not treated in time and regularly, rust spots and oxide scale will increase the rate of corrosion and rust of the steel structure, which will not only affect the service life of the steel structure, but also cause safety hazards.
3. Three effective methods for rust removal of steel structures:
① Manual rust removal
Manual use of scraper , emery cloth , wire brush and other tools to remove rust on steel structural parts. However, this method has low work efficiency and incomplete rust removal.
② Mechanical rust removal
uses electric machinery to remove rust from steel structural parts. However, stubborn oxide scale cannot be removed, and it is easy to damage the metal layer of the steel structure itself.
③ Chemical rust removal (neutral rust remover)
Chemical rust removal mainly uses rust remover (neutral rust remover) to chemically react with rust to peel off the oxide scale from the surface of the steel structure to achieve rust removal. Purpose. It is best to use a neutral rust remover when using rust remover , which can completely solve the shortcomings of acidic rust removers such as acid mist that harms and corrodes the base material.
uses neutral rust remover to remove rust from steel structures, which is low cost, simple to operate and thorough in rust removal. Neutral rust remover is not only suitable for rust removal on steel structures, but also on steel parts and construction site steel bars.
Doing a good job of rust removal is of great significance to the development of steel structure buildings and the reduction of environmental pollution. This steel structure surface rust remover can not only meet the effect of metal rust removal, but also meet the safety requirements of environmental protection for rust removal work. In addition, if it is to be used for a long time without extensive repairs, long-lasting coating protection can extend its service life to 20-30 years, with low maintenance costs and obvious economic benefits.
