Second, the structure and function of the eraser. Most erasers are made of soft rubber or polymer materials, which have good friction coefficient and adhesion, and can easily remove pen marks on paper. In addition, the surface of the eraser is usually treated specially to improve its friction and durability. According to different needs, erasers are also divided into different types, such as soft erasers suitable for removing pencil traces and hard erasers more suitable for removing ink traces of pens or ballpoint pens. Third, things to note when using an eraser. 1. Keep it clean: After using an eraser, it should be cleaned immediately to avoid adhesion when used next time. At the same time, it should be stored separately from other chemicals to avoid surface pollution. 2. Avoid excessive use: Although an eraser can easily remove pen marks, excessive use may cause paper surface hairiness or deformation. Therefore, we should control the force moderately during use. 3. Regular replacement: The surface of an eraser used for a long time may gradually become uneven, so it should be replaced in a timely manner to ensure its cleanliness and effectiveness. In conclusion, although the eraser seems to be just an ordinary study supply in our life, there are many secrets and stories behind it that few people know about. Whether in historical evolution or practical use, the eraser carries human wisdom and emotional value. Let's cherish every study supply around us and explore more secrets and stories behind them!
