Deflocculated Suspension |
|
1.
Particles exist as loose aggregates. |
1.
Particles exist as separate entities. |
|
2. The rate of sedimentation is high. |
2. The rate of sedimentation is low. |
|
3.
Sediment formed rapidly. |
3.
Sediment formed slowly. |
|
4.
Consists of loosely packed particles possessing a Scaffolding-like structure a hard dense cake does not form and the sedimentation can easily redispersed. |
4.
Sediment becomes very closely packed as the repulsive forces between the particles are overcome a hard cake is formed
which is difficult to redisperse. |
|
5.
Elegant preparations are obtained due
to the uniform distribution of loosely
bonded flocs. |
5.
Unsightly preparation results due to the formation of sedimentation. |
