Effect of Graphite Particle Size on Properties of Expanded Graphite

Expanded graphite has excellent properties and is widely used. There are many factors that affect the properties of expanded graphite. Among them, the size of graphite raw material particles has a great influence on the production of expanded graphite. The larger the graphite particles are, the smaller the specific surface area, and the smaller the area participating in the chemical reaction. On the contrary, the smaller the graphite particles, the larger the specific surface area. The following Furuite graphite editor introduces the influence of graphite particle size on the properties of expanded graphite:
Regarding the influence of graphite particle size on the performance of expanded graphite, from the perspective of the ease of chemical intrusion, the particle assembly makes the graphite flakes thicker and the interlayer gaps are deep. . This greatly affects the degree of expansion. If the graphite particles are too small and too fine, the specific surface area will be too large, and the edge reaction is dominant, but it is not conducive to the formation of intercalation compounds. Therefore, if the graphite raw material particles are too large or too small, it is not good for the production of expanded graphite.
The influence of graphite particle size is also reflected in that the particle size composition of the ingredients should not be too wide, the difference between the largest particle and the smallest particle diameter should not be too large, and the particle size composition should be uniform, so that the processing effect is better.
Expanded graphite is generally divided into two types: coil and plate, with a thickness between 0.2 and 20MM. The expanded graphite produced by Furuite Graphite is made of natural flake graphite. It retains its characteristics of high temperature resistance, good lubrication performance and corrosion resistance. Welcome new and old customers to visit and negotiate!
