vulcanizing accelerator

基本解释

There are three purity measuring methods of vulcanizing accelerator NOBS: potentiometric titration, indicator titration and liquid chromatography.
前言：硫化促進劑NOBS純度的測定方法有三種：電位滴定法、指示劑滴定法和液相色譜法。
Insoluble sulfur is a high performance vulcanizing agent of the rubber and vulcanizing accelerator, which is mainly used to produce steel radial-ply tire.
不溶性硫磺是一種性能優異的橡膠硫化劑和硫化促進劑，主要用於鋼絲子午線輪胎的生産。
Through the comparison of the three measuring methods of vulcanizing accelerator NOBS , the reason of adopted potentiometric titration in the revised GB/T8829 is illuminated.
通過對硫化促進劑NOBS三種測定方法優缺點的比較，闡明了脩訂後的GB／T8829 純度測定採用電位滴定法的原因。
