Erasers are one of the indispensable stationery for Xi and work, and among the many erasers, 4B erasers and 2B erasers are particularly common. What exactly is the difference between them?This article will delve deeper into this issue**.

4B Eraser: 4B eraser is usually made of a soft rubber material with high flexibility and elasticity. This makes it easier to erase pencil marks and less likely to damage the paper.

2B Eraser: In contrast, 2B eraser is usually made of harder material and is mostly made of synthetic rubber or plastic. This hardness allows it to apply more pressure when erasing the blot, but it also removes the blot more thoroughly.

4b eraser: Due to its soft material, 4b eraser tends to be gentle when erasing pencil marks, not completely removing the blot, but making it lighter. This is useful for situations where part of the blot needs to be preserved or minor modifications need to be made.

2B Eraser: The 2B eraser is harder and therefore more thorough when erasing the blot. It can completely remove the blot without leaving a trace, which is suitable for occasions where complete blot removal is required.

4B Eraser: Due to its gentle erasing effect, 4B Eraser is more suitable for use in painting, sketching, and other occasions that require fine adjustments. It makes it easy to remove minor mistakes while preserving the texture and texture of the paper.

2B Eraser: The 2B eraser is more suitable for writing, exams and other occasions that need to completely remove imprints. It can quickly clear the wrong writing and improve the efficiency of writing.

According to the designer of a well-known stationery brand, "4B eraser and 2B eraser are designed with the needs and Xi of different users in mind. The 4b eraser is mainly aimed at painting and sketching enthusiasts, while the 2b eraser is more suitable for students and writers. ”

In order to show the difference between the two erasers more visually, we conducted an experiment. In the experiment, we used a 4b eraser and a 2b eraser to erase the same pencil impressions, and the erase effect was evaluated. The results showed that the erasing effect of the 4b eraser was milder and the blot residue was moreThe 2B eraser, on the other hand, removes the blot more thoroughly with less carryover. This is in line with the material differences and erase effects described earlier.

Through an in-depth analysis of the 4B eraser and the 2B eraser, we can draw the following conclusions: there are obvious differences between the two in terms of material, erase effect and application. The 4b eraser is soft and gentle, suitable for fine adjustment occasions such as painting and sketching;On the other hand, the 2B eraser has a higher hardness and is suitable for occasions such as writing and exams where it is necessary to completely remove the blot. Looking ahead, we expect stationery manufacturers to continue to develop more innovative and practical eraser products based on user needs and usage Xi.
