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：硫化促进剂NOBS纯度的测定方法有三种：电位滴定法、指示剂滴定法和液相色谱法。
Insoluble sulfur is a high performance vulcanizing agent of the rubber and vulcanizing accelerator, which is mainly used to produce steel radial-ply tire.
不溶性硫磺是一种性能优异的橡胶硫化剂和硫化促进剂，主要用于钢丝子午线轮胎的生产。
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.
通过对硫化促进剂NOBS三种测定方法优缺点的比较，阐明了修订后的GB／T8829 纯度测定采用电位滴定法的原因。
