Introduction
In 12th grade chemistry subject we touched on how cellulose is created. So by watching this video material we gonna need to answer some questions.
Task
Task: Watch the video material given and answer the following questions!
Process
Questions:
1. Where is cellulose extracted from?
2. What are the main things cellulose is used for?
3. What is done to smaller quantities of wood fiber?
4. Why are eucalyptus trees are suitable for cellulose extraction?
5. Why is the wood transported into the digesting machine?
6. What is Lignin?
7. What does Lignin do in a tree?
8. What is lignin used else for after separation from the fibers?
9. The movement of the wood through out various machines is controlled by what?
10. What is manufactured by specialized cellulose?
Evaluation
Answers:
1. From wood fiber.
2. To create paperboard and paper.
3. So it could be refined to a verity of specialized products.
4. Because they have short fibers.
5. So it could be cooked and the fibers would separate from lignins?
6. Lignin is a substance which binds the cells, fibers and vessels in wood.
7. It combines the cellulose fibers together so the tree could grow up straight.
8. It is used as a replacement for coal to create steam and electricity.
9. By a computer.
10. It is used to create clothes and furnishing materials.
Conclusion
Congratulations you have learned more about the manufacturing of cellulose.
