摘　　要：本文以铁皮硫酸亚铁和氢氧化钠溶液为原料生产920型号氧化铁黄晶种过程中的工艺条件为研究对象,主要从亚铁浓度、投碱量、补水量等几个条件探究其对晶种质量的影响,并对实验产物进行了粒径、色光等检验,发现在:初始亚铁浓度为400 g/L、碱比为0.4、补水转化率为0.05、反应温度在31~40℃等条件下,得到的氧化铁黄晶种颜色优质、色相稳定、颗粒大小比较均匀。本研究对氧化铁黄920晶种的工业生产有指导作用。In this paper,the technological conditions for producing crystal seeds of iron oxide yellow 920 with ferrous sulfate and sodium hydroxide solution are studied as the research subject.Researched the influence of ferrous concentration,alkali dosage and water replenishment etc.on the quality of crystal seeds and tested the particle size,color and light,etc.,we found that under the conditions of the initial ferrous iron concentration 400 g/L,the alkali ratio 0.4,the conversion rate of water replenishment 0.05,and reaction temperature 31~40℃,the obtained iron oxide yellow crystal seeds have high-quality color,stable hue and uniform particle size.This study is helpful to the industrial production of iron oxide yellow 920 crystal seeds.
