2.  Detailed Description of Application in Pencil and Pencil Lead :


The main component of pencil lead is graphite. In fact, the refill of a pencil is made of graphite and clay in a certain proportion. For example, "H" is the prefix of "hard" in English, which represents clay and represents the hardness of pencil lead. The larger the number in front of "H" (such as 6h), the harder the pencil lead, that is, the larger the proportion of clay mixed with graphite in the pencil lead, the less obvious the words are written, which is often used for copying. "B" is the prefix of "black" in English, which represents graphite. It is used to indicate the soft condition of pencil lead and the obvious degree of writing. "6B" is the softest and darkest handwriting. It is often used for painting. The label of ordinary pencil is generally "HB". The pencil mark used to paint the answer sheet during the exam is usually "2B".

The lead core of the pencil is mainly composed of graphite powder and clay. According to the national standard, the pencil is divided into 18 types according to the graphite concentration. In the current standardized examination in China, the computer can only read the pencil handwriting with lead concentration of 2B. Too thick or too light will cause the failure or error of computer reading

Why can graphite powder be used as pencil core? First, it is black; Secondly, it is soft and is one of the softest ores. If it is gently scratched on the paper, it will leave traces. If viewed under a magnifying glass, the pencil trace is composed of very small graphite particles. The hardness and softness of ore is an important index to identify ore types.
