Why can t the erasable pen erase the handwriting?

Erasable pen, which uses special polymer material as ink base material and is assembled by a special process. During the writing process, the ink is wiped by forming a wipeable pigment film on the paper through the tip of the pen.

The handwriting can be erased with an ordinary eraser like a pencil within a few hours, and the remaining handwriting will not be wet when exposed to water, and will not fade after a long time, and after 48 hours, it will become a permanent handwriting that cannot be erased, and can be maintained for a long time. The product looks, writes and other ballpoint pens.

Similarly, there are various colors such as blue, black, and red.

There are 3 types of erasable pens:

1. The magic pen can be erased, wipe with a special correction liquid (magic pen) (ask the store, the store generally knows), wipe it with a non-erasable pen (ballpoint pen, etc., or the store's special carbon pen copy) to copy, it will fade after water, and it will fade after a long time.

2. The eraser can be erased, and it can be erased with an ordinary eraser (it will fade if you touch it often), but don't be too demanding to wipe it too clean.

3. Friction, generally made in Japan, (the quality of domestic is not good), the heat generated by the friction of the rubber at the end of the pen or the cover of the pen on the paper eliminates the handwriting (60 degrees to eliminate, and the handwriting will come out again in the refrigerator) is very expensive, and it can also be erased with an eraser, but the effect is not good (as long as there is heat, it can be eliminated, and fingernails can also be used).

Erasable handwriting is gone, and it can be restored by cooling down.

The wipeable pen is colored at room temperature, and it will become colorless at high temperature. It should be noted that due to the heat-sensitive reaction of the erasable pen, when the weather is hot, it is necessary to put the homework and books that can be written in a cool place. Erasable pen handwriting will disappear, such as ** treatment method, erasable pen handwriting disappears, can be placed in the refrigerator freezer for 15 minutes, and the handwriting will be re-revealed.

The principle of the erasable pen

The ink of the erasable pen is made of a special polymer material, which contains three special components: a chromogenic material, a chromogenic agent and a color-changing temperature control regulator. At room temperature, the combination of the chromogenic material and the chromogenic agent on the paper will form a wipeable pigment film next to the liquid to generate a writing color; When the temperature rises to a certain extent, the color-changing temperature control adjuster will organize the colorogenic material and the chromogenic material to combine and interact, so that the handwriting color disappears and will not recover at room temperature.

It is only when the temperature drops to a very low level that the handwriting reappears. This phenomenon is a "heat-sensitive reaction", and different color-changing temperature modifiers control the discoloration at different temperatures, resulting in different colors and effects. "Heat-sensitive reaction" is used in a wide range of applications, such as water cups, clothes, hair dyes, etc., which change color with temperature.

How to erase the pen:

1. The handwriting of the signature pen can be removed with the word eliminator;

2. The handwriting of the signature pen can be erased with wind oil essence;

3. The eraser can also be wiped off by dipping it in water.

Erasable handwriting will disappear and you will have to write it again.

Erasable handwriting does not disappear on its own at room temperature. At room temperature, the color-growing material and the chromogenic agent combine to produce color, but when the temperature is high to a certain extent, generally above 60, the color-changing temperature adjuster will prevent the color-growing material and the chromogenic agent from combining, so that the color disappears.

Hello, dear. The inks of these erasable pens contain chromogenic materials, chromogenic agents, and color-changing temperature regulators. At room temperature, the chromogenic material and the chromogenic agent combine to form color, but when the temperature exceeds about 60, the color-changing temperature regulator prevents the chromogenic material from binding to the chromogenic agent, causing the color to disappear.

When the temperature drops to a very low level, the handwriting will reappear. The rubber tip at the end of the pen rubs against the surface of the paper, generating heat, making the ink handwriting transparent and looking like it has disappeared, which is called "heat reaction" in chemical terms.

But if he disappears before himself, he has been erased by others, and there is nothing to be found in the vanished one, unless he looks at the light from the side, there may be some marks when he writes hard.

Erasable pens have always been an artifact in the lower grades, and it is inevitable that the lower grades often make typos. If you use an erasable pen, you can erase the wrong place and rewrite it to keep your homework or ** clean. I vaguely remember that I used a erasable pen in the high school entrance examination that year.

In Zibo, there is a "tragedy" related to erasable pens. It turned out that a parent in Zibo found that the handwriting of his child's summer vacation homework had disappeared after plastic packaging. After detailed inquiry, it turned out that their children's summer vacation homework was written with an erasable pen.

The parents couldn't help but laugh when they heard the news, especially when they saw that their children were about to be sad and autistic, and both husband and wife were amused and laughed.

When I was a child, some classmates said that their summer vacation homework was burned or lost by their parents, but it was actually an excuse that they didn't finish it. But how does a student tell a teacher that his summer homework is not ready for his turn? The hard work has just disappeared, and that's the biggest blow before school starts. You can imagine how much it crashed.

So why did erasable pen writing disappear after plastic packaging? It all starts with the composition of the ink in the erasable pen. Common erasable pens are divided into two types: high-temperature decolorization and microsphere capsules. These two erasable pens achieve erasable functionality through the special physical properties of their inks.

The high-temperature decolorization type makes the handwriting disappear through the heat generated by the friction between the eraser and the paper, while the microsphere capsule makes the diameter of the microsphere imitation grinding letter wrapped with pigment greater than the gap of the paper fiber through technical means, so that the microsphere pigment can be taken away with the eraser to realize the function of swimmer and erasure.

In this way, the "unlucky" elementary school students used erasable pens with high-temperature faded colors. In the process of parents taking the homework to the plastic packaging, the plastic packaging needs to be warmed up, so the homework that has been busy all summer vacation disappears. Can I get my lost assignments back?

Of course, since you disappeared because of the temperature change, as soon as you experience a low temperature, the original handwriting will all be revealed. As soon as the child's parents knew about this feature, they put the homework in the refrigerator. After a period of cooling, the original handwriting was returned, but some erased areas also appeared, making them illegible.

I don't know if the child didn't make the homework clear to his parents to press **, or the careless parents made a mistake with the child's homework requirements, which led to this oolong incident. But after this incident, the child is definitely qualified to act as a "man of the hour" in the school, and has the capital to brag among the students.

This erasable "tragedy" has given many parents and students a new knowledge that everyone must remember in the course of future assignments and exams to prevent such a "tragedy" from happening again.

This type of celebration is a method of generating heat by friction of the Lip liquid, and this kind of handwriting will disappear when it encounters heat, so it will disappear if it is generated by friction, but it cannot be restored after this disappears.

Personally, I think that the disappeared handwriting can still be restored, and basically all the notes can be erased if the pen can be erased.

When the wiping pen is at room temperature, the color material and color development, but when the temperature is high to a certain extent, it is generally more than 60, and the color temperature adjuster will prevent the color material and the color developer from combining, so that the color disappears. Lowering and touching the temperature of stupidity will restore the text.

The substance in the erasable pen will gradually change color and become colorless when exposed to light, so it will disappear. Can be restored.

Here's how to recover:

When the temperature exceeds 60 degrees, the ink becomes colorless, put it in the refrigerator, the temperature drops to below minus 10 degrees, and the ink appears again. It is made of special ink and refined by special technology, and is divided into erasable ballpoint pen and erasable gel pen.

Erasable water-based pens (slightly lighter in color than pens), erasable pens, etc. Liquid that volatilizes quickly and has a certain viscosity.

Erasable pen handwriting will disappear after a long time. It disappears when the temperature is higher and fades when the humidity is high. Erasable pens are made of special ink, refined by a special process, and are divided into erasable ballpoint pens.

Erasable gel pens, erasable water-based pens, erasable pens, etc. Liquids that volatilize rapidly and have a certain curvature of viscous socks. The handwriting can be repeatedly corrected with an ordinary eraser.

Characteristics: Erasable pen, which uses special polymer material as ink base material and is assembled by special process. In the process of writing, the ink forms a layer of erasable pigment film on the paper through the tip of the pen, which can wipe the ink, and the handwriting can be erased with an ordinary eraser like a pencil within a few hours, and the remaining handwriting is not wet when exposed to water, and it does not fade after a long time, and it becomes a permanent handwriting that cannot be erased after 48 hours, and can be maintained for a long time.

The appearance and writing of this product are similar to other ballpoint pens, and there are various good colors such as blue, black, and red. Erasable pens are a good choice for routine assignments, but it's better to choose a signature pen when signing important documents or exams. This is because the handwriting of the erasable pen disappears in high temperatures.
