The erasable pen is made of special ink and refined by special techniques. It can be divided into erasable ballpoint pen, erasable gel pen, erasable water pen, erasable pen and so on. A liquid that evaporates quickly and has a certain viscosity.
There are currently 2 types of erasable pens on the market: high temperature achromatic and microsphere capsules. The high temperature change causes the color to disappear by rubbing heat with an eraser, but it develops color when it is cold. The disadvantage is that it is not suitable for long-term storage, and it is more inconvenient to use in winter. It takes a long time to heat up to make the color disappear. The microcapsule erasable pen is a microsphere-encapsulated pigment. The particle size of the microsphere is larger than that of the paper fiber, and the microsphere pigment can be easily erased by the eraser. Can be stored for a long time without fading.
The erasable pen is a good choice for normal work, but it is better to choose a signature pen when signing important documents or exams. This is because the handwriting of the erasable pen disappears at high temperatures. Under the lighter baking, the handwriting of the erasable pen gradually disappeared. Therefore, for the sake of insurance, do not use the erasable pen for important documents such as securities and signatures.
