Mixing of plastic solids is generally facilitated by___________________?
Correct answer: C. Kneading
- A. Dispersion
- B. Mastication
- C. Kneading
- D. None of these
Explanation
Kneading repeatedly deforms and folds highly viscous plastic material, distributing one solid throughout another. Mastication mainly softens or plasticizes materials such as rubber rather than serving as the principal mixing action.
