Chemistry in our lives
Product: Paper
Why do I have this product?
Paper is Casually used in many way's:
from writing, reading, crafting, drawing, and more. And considering school activities and regular day to day action, paper is going to be essential.
What are the main ingredient
Tree pulp
What role does it do in the manufacture
of the product?
After cutting down trees, the raw wood extracted
is then either to create pulp using a chemical process known as "Kraft", or using a mechanical process that can be called "Breaking."
Breaking: when cutting down a tree, the log is sent out to machines that remove the bark, break it, grind it, turn it into a pulp, and then filter it out. After this bleach or coloring might be used.
Kraft: using cut out wooden barks, the barks get cooked out in huge containers called "digesters." that contain sodium hydroxide and sodium sulfide at a high pressure in order to boil the barks, which in turn then get dissolved into a pulp.
What is a tree (Pulp)?
Pulp is basically a watery raw wood that contains cellulose fibers, lignin, and chemicals that went into it's production. When extracting raw wood from trees, the outer shell is made of cellulose which is a fiber, that contains lignin which is an organ found in cell walls of many plants making them rigid and woody, they are the important key part in the making of paper.
What are the negatives?
the making of paper would require a huge sum of trees to be cut down, thus the environment is in a huge disadvantage from the yearly clean-cut that goes for making different types of papers.
How is it manufactured
After the pulp is created, it goes into a large tube where it get subjected into machine beaters, at this stage fillers are added like chalks, clay, or chemicals such as titanium oxide. Afterwords the pulp would be poured into a mesh screen on a series of rollers that would help extract and remove the water, the pulp joint with the mesh screen would go into a multiple of heated cylinders in which they would create dried paper, which then would travel into calendars that would determine what the paper look might be, after a few sizing, and coating the paper would be cut down to it's appropriate size.
The different type of usage: books, cleaning paper, phone book, money, and regular old writing paper.
How is it deposited?
It is recycled for a green way of waste removal, and a 2nd time usage.
