易分散超微细化氧化铁颜料生产工艺

摘要

This paper introduces manufacture technology of ultrafine ferrous oxide pigment of easy-dispersing, the typical work pressure of grinding being 0.91～1.32 MPa , the flow rate being 30～60 m3/min and the output being 300～900 kg/h. Ferrous oxide with Hegman fineness of 0～4.0 can be grinded to Hegman fi neness of 6.0～7.0, with the best Hegman fineness of 7.5.%介绍了易分散超微细氧化铁颜料生产工艺,研磨工作压力0.91～1.32 MPa,流量30～60 m3/min,产量300～900 kg/h。海格曼细度0～4.0的氧化铁原料,研磨后海格曼细度可以达到6.0～7.0,最优数据海格曼细度为7.5。
