Will corrosion become a hidden danger for prefabricated house manufacturers?
In order to solve the problems of shortage of migrant workers and difficulties in building quality control, prefabricated house manufacturers strongly advocate the development of prefabricated integrated structure houses. Compared with concrete structures, this structure has light weight, high strength, good plasticity and toughness, and excellent seismic performance. Advantages, but the structure also has some fire and corrosion problems.
Generally speaking, in the anticorrosion design, the anticorrosion design period is reasonably determined according to the requirements of the building, environmental corrosion conditions, construction and maintenance conditions, and then various factors such as economics are comprehensively considered according to local conditions to reasonably choose an anticorrosion solution. .
Structures are susceptible to corrosion in humid environments. Oxygen and moisture in the atmosphere are important factors that cause the corrosion of civil building structures. Some industrial gases can also cause structural corrosion. The anticorrosion requirements of building structures are not only related to their environmental conditions, but also to building materials. The specific materials, structural forms, use requirements, construction conditions, and maintenance and management conditions are related and should be considered in anticorrosive design and construction.
Although methods such as galvanizing and aluminum-zinc spraying can play a long-term anticorrosive role, they are rarely used in this type of residential structure due to the high cost. Generally speaking, the steel structures used in residential buildings basically use paint as an anticorrosive method.
After surface treatment and painting construction, the corrosion protection of the steel structure is enough to guarantee that it is no longer necessary to repaint in the life cycle of the building. That is to say, for the steel structure housing we are concerned about, corrosion protection is not a problem.
