超细白炭黑粒径指标的纠偏

Correction of Ultrafine White Carbon Black Size Index

粒径是超细白炭黑产品的重要指标,在生产过程中严格控制超细白炭黑的粒径稳定性是极其重要的。本文分别对2017年7~9月份两种超细白炭黑成品(HX728-11和HX928-11)D50和D97指标数据进行搜集并整理,分析了影响超细白炭黑粒径指标不稳定的原因,并提出了相应的改进措施。

The particle size is an important index of ultrafine carbon black products. It is very important to strictly control the stability of ultrafine carbon black in the production process. Two kinds of ultra-fine white carbon black products（ HX728-11 and HX928-11） D50 and D97 index data were collected and sorted in July-9 2017 respectively. The stability of ultrafine carbon black was analyzed and the improvment was put for ward.
