Sammanfattning
The flow of suspension into a macro pore in the base sheet is modeled. Flow velocities close to a pore were found to be high enough to redistribute the coating color locally. Spherical particles are able to "bridge" the pore and prevent other particles from entering the pore. Pores less than three sphere diameters, high particle concentration, and low electrostatic stabilization encouraged the bridging mechanism to occur. The results provide a physical picture that helps explain the improved coating holdout at high solids found in experimental studies.
