Description

technical field [0001] The invention relates to a metal anticorrosion coating, in particular to a nickel-manganese-silicon-containing chromium-free zinc-aluminum coating anticorrosion coating. 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 ...
