硅藻孔径调控技术研究和应用

Application and Research on Aperture Adjustment of Diatomite

针对硅藻土中硅藻的孔结构特征对其应用有较大影响的问题,重点对近年来采用酸浸法、焙烧法、水热法等对硅藻土所含硅藻进行孔径调控的方法进行了综述;同时对硅藻土在助滤剂、载体、保温和建筑材料、填料等方面的应用现状和优点进行了描述,提出了一些存在的问题和不足,展望了硅藻土发展的前景。

According to the problem that the pore structure of diatom has great influences on diatom- ite. This paper focused on the function of controlling the size of the pore on the diatomite by acid leaching, roasting and hydrothermal method in recent years. At the same time, it describes the ad- vantages and application of diatomaite used in filter aid, vectors, construction and heat insulting materials and fillers. It also introduces the shortcoming of current studies and the development of diatomite.
