过滤过程使用的助剂,都可以称作助滤剂。添加助剂可以提高设备效率,降低滤饼水份或改善滤饼机械性质,减少滤布阻塞,延长滤布寿命。但是,通常只把那些能够降低滤饼水份的化合物称为助滤剂。因此,助滤剂有时也被明确称作“滤饼脱水助剂”,或称为“脱水助剂”。本文仅就助滤剂种类及其应用进行简单介绍。 Auxiliaries used in the filtration process can be called filter aids. Adding auxiliaries can increase equipment efficiency, reduce cake moisture or improve filter cake mechanical properties, reduce filter clogging and prolong filter cloth life. However, usually only those compounds that reduce the water content of the filter cake are called filter aids. As a result, filter aids are sometimes also referred to as “filter cake dehydration aids,” or “dehydration aids.” This article only on the types of filter aids and its application for a brief introduction.
