滑石粉白度表示方法对白度值影响的研究

摘要

中国是世界上最主要的滑石粉出口国,影响滑石粉产品价值的最重要的物理性能指标是白度.本文比较了辽宁海城产微细目滑石粉不同表示方法检测的白度值,结合实验数据分析了滑石粉白度的测定和表示方法的现状及存在的问题,提出滑石粉的白度表示方法亟待与国际标准接轨,以提高滑石粉出口的附加值.%China is the most important talc export country in the world.Whiteness of talcum powder is one of the the most important physical properties which influence the price.Comparing with the whiteness values of Liaoning Haicheng micro talcum powder obtained through different representations,and combined with the experimental data,this paper analyzes the current situation and existing problems in the field of the measurement and representation of talc whiteness,and proposes to make an integration with the intemational standards,and more additional value of talc export could be available.
