Eraser Working Principle

The rubber is made of rubber and can erase the traces of graphite or ink. A wide variety of rubber, shape and color are different, there are ordinary fragrant rubber, there are painting with 2B, 4B, 6B and other models of art for rubber, and plastic rubber and so on.

main effect

1, you can wipe the pencil traces, modify the wrong word, and now some can wipe the pen traces.

2, some rubber is very beautiful, can be used as a gift or handicrafts.

3, you can also wipe shoes, cars and other things on the underworld.

Main species

Today, a wide range of eraser to meet the different needs, there are ordinary fragrant rubber, there are painting with 2B, 4B, 6B and other models of art for rubber, and plastic rubber and so on.

Some pencils have a small eraser at the end of the pencil. These erasers are mostly pink, the surface is smooth gum. They have good performance on most occasions, but they sometimes break the paper. If you focus too much, eraser also have the opportunity to break the paper. When the handwriting is wiped off, the eraser will leave the residue on the paper. If the mismanance is good, these debris will leave traces on paper.

Another eraser is a commonly used brown eraser, made of soft and rough rubber. It is designed to facilitate the removal of large areas of traces, and will not break the paper. But this eraser does not erase the handwriting effectively and accurately.

Another artist commonly used eraser called soft rubber. It is mainly made of a gray material, and rubber with rubber. Its strength so that it will not leave the residue, so its life than other eraser to long. It removes the handwriting by "absorbing" the graphite. This eraser can not only wipe the handwriting (in fact it can accurately remove the handwriting), it can also be used to highlight the important part or make the work more detailed. However, it is not good at removing large areas of handwriting, and if excessive heat will stain or even stick to paper.

The soft polyvinyl rubber eraser has a plastic texture and has the same function as an ordinary pink eraser. These erasers are more soft than the pink eraser, so it is less likely to damage the paper. Polyvinyl eraser is generally white.

Material utilization and color processing:

1, most of the plastic raw materials can be recycled, but because of plastic (outlet material) than the general raw materials to be brittle, so only mixed with new materials (raw materials) used together, the maximum proportion of not more than 25% is appropriate, should be customer requirements Standard for the principle. Various types of plastic materials due to the different melting point, the pressure of the injection of different, the production must not be confused.

2, because the plastic products with the color, so the plastic raw materials can be divided into: pumping aggregates, toner, color seed material, as well as the recent emergence of liquid in the plastic raw materials coloring. Pumping tablets of raw materials is the pigment has been mixed into the raw materials, each piece of plastic materials have been colored, so the formation of product color stability and uniformity. Colored powder and color seed material is the use of color or toner mixed raw materials, low cost, and do not store a lot of colored raw materials. But the color is unstable, it is more difficult to control the unity in production.

The working principle is the use of rubber molecules and other substances between the molecules prone to force, and the rubber itself soft texture, does not destroy the paper.

In daily life, even if the writing is the same text, we can tell which pencil is written, which is written in a pen. And write the word with a pencil and write the word with a pen, you must take a different rubber to wipe them off.

Written in a pencil, the handwriting remains on the surface of the paper, and does not penetrate into the interior of the paper, but the pen is different. When writing with a pen, the handwriting will be dipped into the fiber inside the paper, the paper dyed ink color.

When writing with an eraser pencil, it is actually a pencil written on a paper (made of pencil powder). As long as the eraser with a rubber, along the rubber "footprint" pencil handwriting disappeared, that is, rubber on the pencil powder adsorption force, greater than the paper on the pencil powder adsorption. When writing with a pen, wipe the paper's surface and the inside of the paper (the ink in the paper), and the hard powder in the rubber. The working principle of this kind of rubber is like the same thing as using a file, but the eraser of the pencil is erupted by the action of friction.
