涂料中六价铬的标准现状分析

Analysis of Standard Status of Hexavalent Chromium in Coatings

分析了涂料中六价铬的可能来源,讨论了国际相关指令、法规对六价铬的要求及国内现行涂料标准中六价铬限值情况,比较了我国现有涂料标准中六价铬检测方法现状,指出了国内涂料标准六价铬检测方法出现的问题,提出了解决涂料标准中六价铬相关问题的对策。

The paper analyzed the possible sources of hexavalent chromium in coating materials,discussed the related requirements for hexavalent chromium in relevant international directives and regulations,as well as the hexavalent chromium limit in the current domestic coating standards,and compared the status quo of the detection methods for hexavalent chromium in the country's current coating standards.Based on the comparative and analytical results,the paper points out the problems of hexavalent chromium detection methods in the domestic coating standards,and proposes countermeasures to solve relevant problems.
