Do you know these little tricks to prevent rusting of steel structures?
The objects around us all require careful care in our daily lives, from a small ornament by the table to a car or house. Speaking of houses, with the increasing development of steel structure buildings, their maintenance and upkeep have also attracted more and more attention from people.
The service life of steel structure buildings is closely related to the presence or absence of regular rust and corrosion protection, regular fire prevention treatment and protection, and regular deformation monitoring and maintenance.
The design service life of steel structures is usually 50 years, during which the probability of damage due to load usage is not high. Most steel structure factory buildings are damaged due to the reduction of structural mechanical and physical properties caused by corrosion. The "Code for Design of Steel Structures" has certain requirements for anti-corrosion of steel structures that have been in use for 25 years. So, the external coating protection of steel structure buildings meets the requirements for steel structure use. In general, regular annual inspections are required, and dust, rust, and other dirt should be cleaned every three years before painting. In addition, the variety and specifications of the paint should be as consistent as possible with the previous ones, otherwise the two different materials cannot achieve compatibility, which will bring greater harm.
Having said so much, the following methods can be used to prevent rust in steel structure buildings:
1. Chemical oxidation layer protection method
A compound thin film with properties is generated on the surface of steel through chemical or electrochemical methods to isolate the contact between corrosive media and metal.
2. Metal coating protection method
Using metals or alloys with negative or positive protective effects, a metal protective layer is formed on the surface of the metal in need of protection by electroplating, spraying, chemical plating, heat treatment, and infiltration to isolate contact between the metal and corrosive media.
3. Non metallic coating protection method
Using materials such as coatings, plastics, and enamel, a protective film is formed on the metal surface through methods such as brushing and spraying to isolate the corrosive medium of the metal. The non-metallic coating protection method is commonly used in the later maintenance and upkeep process of steel structure buildings. This method is effective and cost-effective; And it has a wide range of options, strong applicability, and is not limited by the construction shape and size; When the temperature changes, it can also expand and contract with the components; At the same time, the appearance is also good.
