Industrial concerns
- Preparation of colloids
The main concern is to make stable dispersions so that the product has an acceptable shelf-life.
- Use of colloids
Colloids, as we have seen, have varied uses. To name a few, they find use in photographic films, catalysis, membrane separation, chromatographic separation, detergency and flotation.
- Handling of colloids.
Colloids are viscous fluids and therefore they behave as non-Newtonian fluids. We need to understand rheology (the science of the deformation and flow of matter) when dealing with issues like transportation and storage.
- Destruction of colloids.
In some situations (like sewage disposal etc.), knowledge of methods of efficiently destroying colloids is also required. |
