An Experiment Study on Squeeze Test and Flow Behavior Analysis of Concentrated Carbon Black Suspension

Carbon black suspension is investigated using a squeezing test, which compresses a disk of paste between two parallel plates, one of which is moving at a constant speed. From this test, the two-phase nature of carbon black suspension can be evidenced. Liquid migration is observed at low compression speed. This test is also a good tool for constructing a two-phase model for paste flow modeling. The concentrated suspension is composed of a powder of activated carbon black and a Newtonian liquid phase.
