[0002] At present, the performance of various anti-corrosion coatings on the market varies. The most suitable for the use scenario of building components is a water-based zinc-aluminum coating, which has good acid and alkali corrosion resistance. However, its specific anti-corrosion effect needs to be tested. The traditional test method is to immerse it in an acid and alkaline solution.
