摘要
超细氢氧化铝具有许多优点,应用广泛。超细氢氧化铝的粒度分布和颗粒形貌对产品的性能有很大影响。根据湿化学法颗粒成核与生长机理从理论上分析了超细氢氧化铝制备过程中需控制的工艺条件,研究了二段分解工艺中晶种添加量和温度等对分解产品粒度分布的影响,得出了温度和种子添加量对氢氧化铝粒度分布的影响规律。
The super-fine aluminium hydroxide is widely used due to its advantages.However,the distribution and appearance of the particle size have much affect on the performances.The paper analyzes the process conditions to be controlled in the preparation of super-fine aluminium hydroxide based on the hydrometallurgical technique and studies the affect of the amount of seed addition and its temperature on the distribution of particle size as well as educes the rule of temperature and the amount of seed addition on the distribution of aluminium hydroxide particle size.
