在表面过滤器分离粉尘的情况下，形成的滤饼结构和颗粒接触上的粘合键对操作行为都有显著影响。本文从微观和宏观两方面对盐颗粒与非吸湿性颗粒接触时的潮解和开花特性进行了探讨。通过环境扫描电子显微镜观察到粘接键的变化以及粉尘饼的重组。在定制的标准过滤器测试台上，研究了通过诱导粉尘饼中盐粒组分的潮解和潮解对测试过滤器性能的影响。
In the case of dust separation with surface filters, both the structure of the formed cake and the adhesive bonds on particle contacts significantly influence the operating behavior. Microscopic as well as macroscopic insights into the characteristics of deliquescence and efflorescence of salt particles in contact with non-hygroscopic particles are presented. By means of an environmental scanning electron microscope a change to the adhesive bonds as well as a restructuring of the dust cake are observed. The change in the performance of test filters by inducing deliquescence and efflorescence of the salt particle fraction in a dust cake is investigated on a customized standard filter testing rig.
