The corrosion reasons and anti-corrosion methods of folding houses

During the application period of spring, summer, autumn, and winter, folding houses are prone to corresponding chemical changes and damage under the effects of air, environmental temperature, water, and other conditions, thereby endangering the beauty and quality of folding houses. So, what are the reasons for erosion? How to resist corrosion? Remind everyone about the knowledge of corrosion resistance in folding houses. The steel prefabricated components of a folding house are always exposed to conditions such as sun, wind and rain, environmental temperature and humidity changes. The O2 and water contained in the air will cause electrochemical corrosion to the steel structure of the folding house, especially the SO2, chloride ion content, and acid rain in the air, which will cause more severe corrosion to the steel structure. Therefore, the hardness of prefabricated components for folding houses needs to be multiplied by one hardness reduction standard value, which is related to the atmospheric environment and service life of the folding house made of rock wool color steel plates. Corrosion in folding houses has always been an unsolvable problem.

There are also plans to improve the corrosion resistance of steel in the folding room workshop. According to the electrochemical principle of steel corrosion, as long as the formation of corrosive batteries is destroyed or the progress is strongly obstructed, corrosion of light steel structures can be avoided. The current universal method of using protective layers to place steel prefabricated components for corrosion is to spray paint on the frame of the folding room and the iron sheet of the rock wool color steel plate to prevent corrosion. The surface layer of the metal material forms a protective film, allowing the metal material to protect against the corrosive components in the atmosphere.
