How to do aluminum magnesiummanganese roofing panel anticorrosion ?

Date of release:2019-03-20 Author: Click:

 Before the anti-corrosion construction of aluminum-magnesium-manganese roofing panels, some pre-treatment measures are required. The pretreatment is more economical and practical for later use. The more pretreatment methods used in the mainstream are chemical methods, which are more treated with acidic or alkaline solutions. The effect is to make the surface of the aluminum-magnesium-manganese roof panel. The oxide is dissolved and the surface oxide layer, rust and oil are removed and the next step is taken.

Generally, when some anti-corrosion measures are applied to aluminum-magnesium-manganese sheet materials, corrosion inhibitors will also be used. However, the aging time of corrosion inhibitors will also pass after a long time, so the aluminum-magnesium-manganese sheet roof anti-corrosion work will last twice a year, at least Once every two to two years.

Chemical method For the pretreatment of the aluminum-magnesium-manganese sheet roofing system for anti-corrosion work, if the wastewater treatment is improper, the environment will be polluted, so pay attention to the discharge of chemical substances. Because of the chemical impact on the environment, this method is now gradually withdrawing from the pretreatment of the aluminum-magnesium-manganese sheet roofing system. The most common method used now is mechanical treatment.

Introduction of mechanical aluminum magnesium manganese board roof anti-corrosion pretreatment method:

The general treatment aspects are shot peening and shot blasting.

Shot peening: shot peening and sand blasting together form the shot peening method. The shot peening method has obvious effect on the surface treatment, but the grinding force is relatively large, so the ultra-thin board is easily deformed. Sandblasting has the best cleaning effect and is suitable for surface treatment of various workpieces.

Shot blasting method: the centrifugal force is used to accelerate the projectile and throw it onto the surface of the workpiece to achieve the effect of cleaning. However, the shot blasting method has high requirements for the site, so it is easy to leave the dead corner clean.

The corrosion rate of aluminum-magnesium-manganese board roof is regular: fast and slow first, the coastal area is faster because of the humid environment, heavy industry is much higher than mountainous area and pastoral area; no anti-rust layer, outdoor air will increase the degree of corrosion, aluminum magnesium manganese The use of anti-corrosion performance in the design of the board roofing system is the focus of the next improvement. It involves the cost, durability, performance, maintenance costs and other issues of the aluminum-magnesium-manganese sheet roofing system.
