Problems solved by technology

[0005] At present, there are industrial applications of chromium-free Dacromet technology at home and abroad, but the corrosion resistance of the coating is significantly lower than that of traditional Dacromet coatings, and it needs to be used with another organic coating, which greatly increases the cost
The cost of chromium-free zinc-aluminum coating is much higher than that of zinc-chromium coating, so its price is high

Description

technical field [0001] The invention relates to a metal anticorrosion coating, in particular to a chrome-free zinc-aluminum coating anticorrosion coating containing magnesium-manganese-silicon. Background technique [0002] Chromium-free zinc-aluminum coating is a new surface treatment material developed to meet the VOC regulations of various countries in the world and the environmental protection requirements stipulated by the coating industry, replacing the traditional Dacromet zinc-chromium coating process. [0003] Dacromet is the transliteration and abbreviation of DACROMET, abbreviated as Dacromet, Dacromet, and Dickron. Domestically named zinc-chromium coating, it is a new type of anti-corrosion coating with zinc powder, aluminum powder, chromic acid and deionized water as the main components. Its anti-corrosion principle is to use hexavalent chromium ions in chromium salts to passivate the zinc and aluminum flakes in the coating to improve the anti-corrosion ability...
