Important signature, do not use this pen Cixi this pen factory to tell you that the word "word" disappears

There are often such shots in martial arts novels. A yellowed paper is baked on the fire, and the words are immediately displayed. It is a secret to the martial arts.

The disappearance and appearance of the words are not mysterious in the eyes of Cixi Aiken Pen Co., Ltd., because their pens can do it.

This is a pen called "Thermal Erasable". It is not a secret to write this pen.

Shen Changchun, general manager of "Ai can make pens," said that the original reason was that pencils used a lot of wood and were not environmentally friendly, so they wanted to find an alternative pen. To replace the pencil, you need to "wipe", that is, you can clear the written words.

The “Thermal Erasable Pen” looks like a neutral pen that is used in peacetime. It is also a black and blue ink, but an eraser part is added to the pen cover to erase the writing.

However, unlike the eraser of the traditional pencil, the eraser of the "thermally erasable pen" is nothing more than a piece of plastic, and its erasable is actually hiding the word.

For example, when a person enters the sensor door, the sensor of the door receives an open command, such as a small ant whose size is too small to drive the sensor, that is, volume is a physical indicator of induction. So similar to the principle of the induction door, the "thermal erasable pen" ink is equivalent to installing a "sensor", the difference is that its command is temperature, the temperature is high, the written words will disappear automatically. When placed in a low temperature environment, those words will show up again.

According to this principle, it is not difficult to understand that a piece of plastic can be used as an eraser because the plastic rubs against the paper during the process of erasing, generating temperature, so that the font disappears.

In 2014, “Ai can make a pen” for the first time to introduce this kind of induction ink from Japan at a high price, and intends to make it into a pen.

What Sun Chunchun did not expect was that the first batch of pens assembled had only one day of "life" and could not be written the next day. He can only detect one pen and finally find the problem in the pen. "The particles of this ink are thicker than ordinary ink, and the ordinary pen will be blocked when written."

Shen Changchun began to look for matching pens. The matching experiments that have been done by light have not been dozens of times. This has found the right pen. It is said that the machine for this kind of pen is imported from Switzerland. Four million yuan.

Finally, the "thermal erasable pen" was successfully produced, and Shen Changchun issued the first order with great enthusiasm. Unexpectedly, after receiving the goods, the other party found that none of the pens could be written.

"We use ordinary packaging to load the car, but the temperature of the car on the road in summer is as high as 50 degrees. When the temperature is high, the ink is not directly developed, and there is no trace on the paper." However, at that time, Shen Changchun had no experience until Return the goods and recheck. “In fact, as long as the customer puts the ice in the refrigerator, it will be back to normal.”

This lesson, Shen Changchun paid more than 1 million yuan in "tuition fees", which also made him begin to ponder the way to transport this special pen. “Later, as long as we ship to high-temperature areas, we use a foam box to insulate it. It also improved the ink and raised the original 50-degree 'invisible' zero point to about 60 degrees, so that it can basically get through most parts of the country. The summer is hot."

Last year, Shen Changchun began to sell this "invisible pen" on a large scale, selling more than 60 million a year.

The most interesting thing is Shen Chang's promotion plan, buy a box of pens with a hair dryer, called the "learning suit." Many people are attracted by this cross-border combination. What is curious about the hair dryer?

Shen Changchun demonstrated it. He wrote a word on a piece of paper, then blow it with a hair dryer. The words disappeared and the paper could be rewritten. “Like a student who is very expensive, using our pen, the paper can be reused.” However, he joked that if you want to write an important signature, remember not to use this pen!
