Final answer:
In the manufacture of paper, logs are cut into small chips, which are stirred in an alkaline solution to break down lignin and separate the cellulose fibers. The alkaline solution softens and dissolves the lignin, allowing the cellulose fibers to separate. After further processing, the pulp is pressed and dried to form paper sheets.
Step-by-step explanation:
In the manufacture of paper, logs are cut into small chips, which are then stirred into an alkaline solution. The purpose of stirring the chips in the alkaline solution is to break down lignin, a complex polymer that holds the cellulose fibers together. By breaking down the lignin, the cellulose fibers are separated and can be used to make paper.
During the stirring process, the alkaline solution helps to soften the lignin and dissolve it, allowing the cellulose fibers to separate. It also helps to remove any impurities or contaminants present in the wood chips.
After the wood chips have been stirred in the alkaline solution, they undergo further processing to remove water and form a pulp. This pulp is then pressed and dried to form paper sheets.
