What should I do if the words written on the whiteboard with marker can't be erased?

First cover the painting marks of the marker in front with a whiteboard pen, and then gently wipe them off with a cotton cloth dipped in a little alcohol.

Marker pen (English: marker pen or marker pen), also known as marker pen. It is a drawing color pen specially used for writing or painting. It contains ink and usually has a pen cover, usually with a hard and soft nib.

The pigment of marker pen is volatile and can be used for quick drawing at one time. It is often used to design articles, advertising slogans, posters or other artistic creations. You can draw thick lines with little change. Box-head pen is a kind of marker pen.

At present, marker pens are also divided into water-based and oil-based inks. Water-based ink is similar to colored pen, and contains no oil essence. Oily ink is more irritating and volatile because it contains oil essence. If the paint falls off the toy, you can use a marker to make up the color.

A whiteboard pen is a tool for writing on a whiteboard, similar to chalk on a blackboard. This pen uses ink as ink, and can be written on a smooth whiteboard and wiped clean with the whiteboard. Whiteboard pens contain chemical raw materials, which will have the taste of chemical raw materials.

After the ink is solidified, a layer of mucous membrane is formed on the surface, which becomes strip or block particles after wiping, and will not leave stains on the board or eraser. In the field test, finger can be used instead of eraser to measure its effect. When writing intermittently, you don't wear a pen cover, never bask in your head, and write fluently. This kind of pen is at the leading level in the same industry, and it can still write smoothly after being dipped in water, so that the pen is completely exposed to the air without a pen cover, and it can write smoothly again no matter how long it takes.

Can be divided into alcohol ink whiteboard pen, water-based ink whiteboard pen. Generally, the whiteboard pens on the market are alcohol-based whiteboard pens. Because of technical problems, the technology of water-based whiteboard pen is immature and the quality is unstable, so the output is small, and it is still in the exploration stage. The use of water-based whiteboard pen is also related to the region. The dry climate in the north is better. If the air humidity is high in the rainy season in the south, it will affect the use of water-based whiteboard pens.

By structure

Can be divided into disposable whiteboard pen, water whiteboard pen, direct liquid whiteboard pen, pneumatic whiteboard pen and so on. The structure of whiteboard pen is roughly composed of pen head, cotton core, pen holder, pen cap and pen tail. Disposable whiteboard pen is welcomed by people because of its economy, practicality and low development cost. The disadvantage is to throw it away after use, resulting in a waste of resources.

The structure of the whiteboard pen with water is similar to that of the disposable whiteboard pen, except that there is a unscrewing device at the front end of the pen holder, and the ink added by the whiteboard pen can be unscrewed after writing ink.

The invention has a disposable and replaceable pen core, the disposable structure is simple, and the whole pen holder can hold ink. The pneumatic whiteboard pen has a complicated structure, and there are airbags and spring devices in the pen holder, which has a large amount of ink storage and smooth writing. Some domestic researchers have removed the spring device in the whiteboard pen, and the function of the spring can be realized through the rubber bowl.
