目前,砂状氧化铝生产采用的分解工艺流程主要有:Ⅰ段连续、间断分解;Ⅱ段双系列连续分解,以及Ⅱ段混联连续分解。分解仍用下列三种传统方法:1,基于粒子长大的分解方法,把较粗颗粒的氢氧化铝种子加入到精液中使粒子长大;2,基于粒子附聚长大的分解方法,把细颗粒氢氧化铝种 At present, the saponified alumina production process used in the decomposition are: Ⅰ continuous, intermittent decomposition; Ⅱ series of two series of continuous decomposition, and Ⅱ continuous decomposition of the mixture. Decomposition still use the following three traditional methods: 1, based on the particle growth decomposition method, the coarse particles of aluminum hydroxide seeds added to the semen so that particles grow; 2, based on particle agglomeration growth decomposition method, the Fine particle aluminum hydroxide species
