Tips for identifying the advantages and disadvantages of whiteboard ink

In addition to the novel and peculiar appearance of a general good whiteboard pen, the quality of the ink is also crucial. If we open the pen cap with a pungent smell, it will make us feel very uncomfortable; It would be even more disappointing if it could not be erased on the whiteboard. This will not only affect our mood, but also reduce the efficiency and quality of our work and study. How to identify the advantages and disadvantages of whiteboard ink? Generally, it can be judged through the following simple and easy methods:

The first is the smell. Most of the white board pen inks on the market are alcohol soluble inks; The main solvent medium is fatty alcohol. Generally, alcohol is used as the main solvent with other additives. Now the technology is becoming more and more mature, and has been widely used. It is the main variety of white board pen ink on the market. After the cap of a good whiteboard pen ink is opened, only a slight alcohol smell slowly wafts out without any other bad smell. If there is any other pungent smell, it indicates that the ink may contain ingredients harmful to human body, such as masking agent and banana water.

The second is intermittent writing (also known as taking off the cap for moisturizing, and some foreign materials also call it anti drying time or anti drying time). Generally, according to the European standard: when the temperature is 22 ℃ ~ 25 ℃ and the humidity is 50%, you can still write normally without a pen cap after a certain period of time. Commercial inks only last 3-4 hours. Good inks can last for 8, 12, or 24 hours, or even 72 hours, depending on the origin. However, with this change, other properties will be affected.

Thirdly, erasability. Erasability is generally divided into instant erasability and delayed erasability. Instant erasability means that it is easy to erase it with a board eraser or a soft cloth after 30 seconds on the whiteboard without pasting the board or leaving a "ghost"; Delayed erasability (also known as board retention time) means that the handwriting written on the whiteboard can still be erased after a period of time. Generally, it varies from a few days, a dozen days, or dozens of days according to the user's requirements. The length of retention time also reflects the actual level of ink. Generally, it is better to have a long retention time.
