达克罗是 DACROMET 的译音和缩写,简称达克曼、达克锈、迪克龙、锌铬膜,是当今国际上金属表面处理具代表性的高新技术,是一种经过脱脂——抛丸——涂覆——固化——冷却——成品的工艺过程,在加工件表面形成由片状锌粉、铝粉及金属铬盐组成的银灰色的防腐蚀涂层。本文从集装箱紧固件的腐蚀环境以及对涂层耐腐蚀性能的要求,对比目前在使用的电镀锌、热浸锌工艺,来探讨达克罗在集装箱紧固件应用上的可行性。
Dacromet is DACROMET transliteration and abbreviation, referred to as Duckman, Duck rust, Dicron, zinc-chromium film, is the international representative of the metal surface treatment of high-tech, is a degreasing - shot blasting - - Coating - curing - cooling - the finished product process, the workpiece surface formed by the sheet of zinc powder, aluminum and chromium metal salt consisting of silver gray anti-corrosion coating. This article discusses the feasibility of Dacromet in the application of container fasteners from the corrosive environment of container fasteners and the requirement of corrosion resistance of the coating, compared with the currently used electrogalvanizing and hot-dip zinc technology.
