Experimental comparison of anti-corrosion effect

Experimental results: Zhongtuo nano-insulation composite metal plate has no change in appearance, aluminum-magnesium-manganese surface is slightly oxidized, and stainless steel 304 plate surface is seriously corroded; nano-insulation composite metal plate has good acid and alkali resistance, chemical resistance and other properties. Color steel plates are not resistant to acid and alkali, and can be used for less than 3 years in a corrosive workshop environment. In the workshop environment where corrosive gas or liquid is easily generated, the lifetime of Zhongtuo nano-insulation composite metal plate is more than 3 times of color steel tile.
