Expanded graphite is a kind of graphite, which can expand and shrink in high temperature environment. This material has very special physical and chemical properties. Graphite is a kind of carbon element, its structure is formed by hexagonal carbon atoms connected, under normal circumstances, graphite can be completely melted, but at high temperature, due to the enhancement of the interaction force between carbon atoms, graphite can form a more stable structure, so as to achieve the effect of expansion.

Development of 1. Expanded Graphite

The development of expanded graphite can be traced back to the 1960 s, when scientists discovered that within a certain temperature range, graphite can be deformed regularly, and the deformed graphite can remain stable. Subsequently, scientists found that under certain conditions, graphite at high temperatures can be used to make a variety of structures, and these structures can be used to support greater weight, thus developing the technology of expanded graphite.

Use of 2. expanded graphite

The use of expanded graphite is very wide, it can be used to manufacture a variety of structures, such as bridges, buildings and so on. In addition, expanded graphite can also be used to manufacture electronic products, such as chips, printed circuit boards, etc. In addition, expanded graphite can also be used in space technology, such as spacecraft, space stations, etc.

Use steps of 3. expanded graphite

1. First of all, it is necessary to determine the temperature of expanded graphite. Generally speaking, the temperature range of expanded graphite is 400-800 ℃. In this temperature range, the structure of expanded graphite can change. 2. Secondly, place the expanded graphite at the specified temperature and wait for the expanded graphite to complete the deformation. When the deformation is completed, it can be used to manufacture structures or electronic products. 3. Then, the expanded graphite can be restored to its original state after cooling, so that it can be reused many times, and the use efficiency of the expanded graphite is improved.

Advantages and Disadvantages of 4. Expanded Graphite

Advantages: 1. It has very superior physical properties, can resist high temperature, corrosion resistance, wear resistance and other characteristics, and can meet the requirements of various special environments. It can be deformed at high temperatures and can be used to manufacture various structures, such as bridges and buildings, which can support greater weight. 3. It can be restored to its original state after cooling, and can be reused many times, which improves the use efficiency of expanded graphite. Disadvantages: 1. The cost is high, and not all applications can accept this cost. 2. The temperature range is also limited. Once the temperature range is exceeded, the expanded graphite will fail. 3. The ratio that needs to be carried out, otherwise it may affect the performance of expanded graphite.

The emergence of expanded graphite has brought convenience to our lives and changed our way of life, making our lives greener and more energy-efficient. Its emergence, let people marvel, but also let people have a greater vision, it brings us unlimited possibilities, let us believe that the future of science and technology will be more developed, to bring us more miracles.
