Question

Arrange in the proper sequence the process/procedure for making paper.
A. The pulp is cooled in large digesters.
B. The pulp is sent to refiners where the fibers are cut to a standard size.
C. It is bleached and put into a beater where color and size can be added.
D. It is blown under pressure to separate the fibers and remove extraneous materials.
E. The paper is dried and calendered.

• A. A, B, C, D, E
• B. A, D, C, B, E
• C. A, C, B, D, E
• D. A, C, D, B, E

Hint:

The basic paper making process is: \textbf{Pulping} (making the slush) \(\rightarrow\) \textbf{Beating/Refining} (preparing the pulp) \(\rightarrow\) \textbf{Forming} (making the sheet on a screen) \(\rightarrow\) \textbf{Drying/Finishing} (pressing and smoothing).

Answer 1

The Correct Option is C

Step 1: Initial cooling
After the raw material (wood pulp) is cooked, the pulp is cooled in large digesters to stabilize it. So, the process begins with A. 

Step 2: Bleaching and addition of additives
Next, the pulp is bleached and beaten, where chemicals, colors, or sizing materials are added to improve brightness and texture. So, the second step is C. 

Step 3: Fiber separation
The pulp is then blown under pressure to separate the fibers and remove unwanted materials. So, the third step is D. 

Step 4: Refining
Once cleaned, the pulp is sent to refiners where the fibers are cut to the desired size for uniform paper formation. So, the fourth step is B. 

Step 5: Final finishing
Finally, the paper sheet is dried and calendered (pressed through rollers) to achieve smoothness and finish. So, the last step is E. 

Final Answer:
\( \boxed{A \;\rightarrow\; C \;\rightarrow\; D \;\rightarrow\; B \;\rightarrow\; E} \)
