HB and 2B are both a mark on a pencil. The difference is that:
1. The black of these two pencils is different. 2B pencil has a higher blackness and draws a relatively dark trace, while HB pencil has a lower blackness and draws a relatively light trace.
2. The lead hardness of these two kinds of pencils is different. The refill of 2B pencil is soft, while the refill of HB pencil is hard, so it is not easy to break when used.
Come on, a picture tells you the significant difference ~ ~
The above is the basic difference between two kinds of pencils with different labels. According to my experience, share some knowledge about the difference in use ~ ~
1, HB pencil-suitable for 1-2 grade pupils.
In fact, my children used HB pencils to study in the first grade, because HB pencils are suitable for students in the lower grades of primary schools, mainly because they are not easy to break. Schools and teachers also require junior students to use HB pencils to study.
In addition, according to the teacher's feedback, HB pencil is more suitable for the first and second grades of primary school because the memory of words in lower grades is not solid at this time, so don't write too dark. In order to facilitate wiping when writing mistakes, HB pencil is selected.
2, 2B pencil-suitable for drawing answer sheets and sketches.
When I am in senior grade, for example, my child's school is in grade three, I need to draw an answer sheet. When I was a student, I began to use the learning method of drawing answer sheets in high school. When drawing answer sheets in this exam, especially multiple-choice questions, we have requirements, that is, we must choose 2B pencils. Because the pencil density of 2B is black enough, the hardness is OK when applied in a small area. The key is to meet the requirements of machine bidding. If it is HB, the color is too light, and the machine can easily recognize the answer. I used to answer questions with hb pencil, so everyone must pay attention to this.
The second is sketching. For beginners, it is easy to control the hand strength to hurt the paper if it is hard, and it is easy to paste into a ball if it is soft. 2B is generally the most suitable for beginners to outline and project the basic shadow, because 2B is soft and moderate, easy to color and erase.
The above is about the difference between hb and 2b pencils.
My personal suggestion is that parents can decide according to their children's strength. If the children below the second grade of primary school are strong, it is recommended to choose hb pencil; If you are weak (for example, some girls), you can consider choosing 2B pencil. You must choose 2B pencil for the exam answer sheet.
The above is my experience about the difference between hb and 2b pencils. I hope I can help you ~ ~ ~ Leave if you like ~ ~
