I wonder if you write with an overheated erasable pen? With the development of the times, the pencil ball point pen we often used when we were young seems to have become a thing of the past, and the favorite of contemporary primary school students is the hot erasable pen and rub easy erasable pen, but the hot erasable pen makes people feel magical that the handwriting will disappear in case of heat. Do you know what the principle is?
What is the difference between hot wipe and magic easy wipe?
The eraser specially used for erasable water-based pen is that the water-based pen can be wiped off with an eraser like a pencil, and there is no need for correction fluid.
It can be wiped when it is hot, it will be restored when it is cold, and it can disappear when it is hot. It can be wiped without rubber, and the ink has no peculiar smell. For a long time before, students used correction fluid to correct typos in order to write neatly. Later, it was exploded that the correction fluid was toxic and hot erasable, which replaced the correction fluid.
When the temperature of the thermal ink used for rubbing pen exceeds 60 ℃, the ink becomes colorless. Put it into the refrigerator, the temperature drops below minus 10 ℃, and the ink appears again.
The price of this pen is much higher than that of ordinary water-based pens. Only the price of replacing the refill is 8 to 12 yuan, while the price of 0.5mm erasable neutral friction pen is 12 yuan, and the price of 0.4mm ultra-fine steel ball erasable neutral friction pen with 10 different colors is 17 yuan.
In addition, this pen also has a fluorescent pen series, which can be recovered at low temperature after erasing, and the price is about 15 yuan.
Principle of thermal erasable pen:
Heat erasable pen oil is a kind of material that decomposes or weakens the affinity with paper when heated, and the handwriting is not easy to preserve for a long time. If there is no word in case of heat, you can put it in the refrigerator and refrigerate it.
