标准范围

ISO 21870:2005描述了一种定量测定炭黑加热（热解）损失的方法，该方法是由于消除了挥发性物质，而不是加热到125°C时释放的挥发性物质（ISO 1126）。该方法适用于橡胶工业用炭黑。它用于评估炭黑表面存在的官能团和吸附物质（例如碳氢化合物）的分解。

ISO 21870:2005 describes a method for quantitative determination of the loss on heating (pyrolysis) of carbon black due to the elimination of volatile materials other than those liberated when heating to 125 °C (ISO 1126). The method is applicable to carbon black for the rubber industry.It serves to assess the decomposition of functional groups and adsorbed substances (e.g. hydrocarbons) present on the surface of the carbon black.
