中文名称：橡胶混合成分 沉淀二氧化硅 用圆盘离心机测定骨料粒度分布

英文名称：Rubber compounding ingredients — Precipitated silica — Determination of aggregate size distribution by disc centrifuge

发布日期：2019-10

标准范围

This document specifies a general method for determining the aggregate size distribution (ASD) of silica by using a disc centrifuge according to the principle of sedimentation. As pre-stage the silica is de-agglomerated in water using strong ultrasonic power treatment.
The method is used for precipitated silica.
