style="text-indent:25px">達(dá)克羅是DACROMET譯音和縮寫，簡(jiǎn)稱達(dá)克羅、達(dá)克銹、迪克龍。國內(nèi)命名為鋅鉻涂層，是一種以鋅粉、鋁粉、鉻酸和去離子水為主要成分的新型的防腐涂料。達(dá)克羅較早誕生于二十世紀(jì)五十年代末。在北美、北歐寒冷的冬天，道路上厚實(shí)的冰層嚴(yán)重阻礙機(jī)動(dòng)車的行駛，人們用鹽撒在地上的方法來降低凝固點(diǎn)的溫度以緩解道路暢通問題，但是緊接而來的氯化鈉中的氯離子侵蝕了鋼鐵基體，交通工具嚴(yán)重受損、嚴(yán)峻的課題出現(xiàn)了。美國科學(xué)家研制了以金屬鋅片為主同時(shí)加入鋁片、鉻酸、去離子水做溶劑的高分散水溶性涂料，涂料沾在金屬基體上，經(jīng)過全閉路循環(huán)涂覆烘烤，形成薄薄的涂層。達(dá)克羅涂層技術(shù)得到推廣，呈燎原之勢(shì)。</p><div
