I think many people used pencils when they were young, because for us who were curious when we were young, pencils are cheap and easy to make mistakes in the learning process. Words written with pencils are easy to drop, which can save paper resources. However, as we grow up, pencils appear less and less in our lives, because pencils are easy to drop. Therefore, it is not very recommend in both life and work.
rubber manufacturers: have you ever thought about what is the rubber?
Why the eraser can easily drop the pencil? Moreover, after the paper, there is no trace. Today, we have seen a long time. First of all, let's take a look at the paper we use for writing. We feel beautiful and smooth, but in fact these papers are made of wood pulp fibers. Therefore, after enlarging the surface of the paper dozens of times, the surface of the paper is actually uneven, and we can see some convex parts and grooves left by the wood pulp fibers, but thanks to this structure of the surface of the paper, the pencil can leave a mark on the paper. What does it mean?
It turns out that the black pencil lead in the pencil is actually graphite and cohesive soil. After adding water and stirring, it is fired and qualitatively made. However, the graphite lead after this special treatment has good softness and adsorbability and is made of graphite, so the color looks very black. Due to the strong adhesion of the black pencil lead and the unevenness of the surface of the paper used for notes, the graphite on the pencil lead will wear when contacting the paper when you writing, adsorbed on the paper, you can see the clear color pencil you wrote.
So, what is the structure of the rubber? Why can you simply wipe the adhesion of strong graphite powder? The eraser is made of rubber. Unlike the smooth plane of the paper, most erasers have relatively clear concave and convex surfaces. Therefore, when the two rub each other, the eraser has stronger friction. Therefore, compared with the paper, the eraser uses stronger friction to remove the paper, peel the graphite off the surface of the paper, and then adsorb the graphite on the eraser, thus forming many rubber ashes, make the paper clean.
But at the beginning, the rubber is made of natural rubber, because of the high toughness of this rubber, when the graphite powder will be adsorbed on the rubber, the more dirty the paper, can not get the desired effect.
