面向21世纪的化工沉淀技术

Chemical precipitation technology towards 21th century

将沉淀过程分解为混合、成核、生长、陈化、团聚等子过程 ,分析了各子过程形成的理论基础。2 1世纪的化工沉淀技术由传统工艺与界面现象相结合而产生。主要介绍了均匀沉淀、反萃沉淀、乳状液膜沉淀、喷雾沉淀等四种沉淀技术。

By?decomposing the precipitation process into some sub processes as mixing,nucleation,growth,ageing and aggregation,the theoretical fundament forming every sub process was analyzed.The chemical precipitation technology in 21th century will be formed by combining traditional process with interface phenomenons.The four mainly precipitation technology such as homogenous precipitation,stripping precipitation,precipitation in emulsion liquid membrane,and spray precipitation were introduced.
