Expansion graphite is a kind of graphite that can expand and shrink in high temperature environments. This material has very special physical and chemical properties. Graphite is a kind of carbon, and its structure is connected by hexagonal carbon atoms. Generally, graphite can be completely melted, but at high temperature, due to the enhancement of the interaction between carbon atoms, graphite can form more stable stability The structure of the expansion is achieved.

1. The development of expansion graphite

The development of expansion graphite dates back to the 1960s. At that time, scientists discovered that graphite can be deformed regularly within a certain temperature range, and the translucent graphite can remain stable. Subsequently, scientists also found that under certain conditions, graphite at high temperature can be used to create a variety of structures, and these structures can be used to support greater weight and develop the technology of expanding graphite.

Second, the purpose of expanding graphite

The use of expansion graphite is very wide. It can be used to create a variety of structures, such as bridges and buildings. In addition, expansion graphite can also be used to manufacture electronic products, such as chips and printing circuit boards. In addition, expansion graphite can also be used for space technology, such as spacecraft and space stations.

Third, the use of expansion graphite

1. First of all, the temperature of the expansion graphite needs to be determined. Generally speaking, the temperature range of the expansion graphite is 400-800 ° C. In this temperature range, the structure of the expansion graphite can change. 2. Secondly, place the expansion graphite at the specified temperature and wait for the expansion graphite to complete the deformation. When the deformation is completed, it can be used for manufacturing structure or electronic products. 3. Then, the expansion graphite can return to the original shape after cooling, so that it can be repeatedly used, which improves the efficiency of expansion graphite.

Fourth, the advantages and disadvantages of expanding graphite

Advantages: 1. It has very good physical properties that can resist high temperature, corrosion, and abrasion, and can meet the requirements of various special environment. 2. It can be deformed at high temperature and can be used to make a variety of structures, such as bridges, buildings, etc., which can support greater weight. 3. You can reply to the original shape after cooling, and you can use it repeatedly to improve the efficiency of expansion graphite. Disadvantages: 1. High cost, not all applications can accept this cost. 2. The temperature range is also limited. Once the temperature range exceeds the temperature range, the expansion graphite will fail. 3. The proportion that needs to be performed, otherwise it may affect the performance of swelling graphite.
