降低钛白粉成品筛余物的研究

Study on lowering residue on sieve of titanium pigment

通过对钛白粉成品筛余物偏高的原因进行分析，有针对性地从生产设备和工艺两个方面进行改进，使钛白粉成品细度指标由改进前的0．05％～0．1％降低到改进后0．05％以下，达到国内优等品的细度要求。

The problem of residue on sieve of titanium pigment is high was analyzed. The equipments and technics were improved. The fineness of titanium pigment lowered to 0.05% below from 0.05% -0.1%, which meets the requirement of high - class products.
