Structure description | Research methods | Findings |
Layered structure | Analyzed the change of mechanical characteristics for cakes | The physical model of the layered structure of the filter cake is established |
grid structure | Double layer theory | The structure of filter cake is a kind of space grid structure |
pore structure | Freeze drying technique and scanning electron microscope | The filter cake shows a honeycomb pore structure |
Structure fractal | Fractal theory | The cake structure is a piecewise Sierprinski fractal |
