Adhesives
1. Why does roughening a clean metal surface often improve an adhesive bond?
- A. It increases effective area and mechanical interlocking
- B. It eliminates all intermolecular forces
- C. It makes the metal chemically inert
- D. It guarantees zero residual stress
View answer and explanation
Answer: A. It increases effective area and mechanical interlocking
Controlled roughening can increase contact area and provide microscopic features into which adhesive can key.
Polymers
2. The molecular mass of a polymer is obtained by multiplying mass of the monomer unit the degree of polymerization. The degree of polymerization of PVC is 1000. What is molecular mass
- A. 65000
- B. 63000
- C. 62000
- D. 60000
View answer and explanation
Answer: B. 63000
Molecular mass x x ,000; the keyed answer is B (63,000).
