The expanded graphite sheet itself has low density, and has good bonding performance with the coupling surface as a sealing material. However, due to its low mechanical strength, it is easy to break during work. Using expanded graphite sheet with high density, the strength is improved, but the elasticity is reduced, and the combination with the coupling surface is deteriorated. The following Furuite graphite editor introduces how expanded graphite can be used as a multi-layer sandwich composite material:
How to play the advantages of the two materials? If the materials with these two properties are combined, that is, expanded graphite with a higher density is used for the inner layer, and flexible graphite material with a lower density is used for the outer layer. The shortcomings of the two materials used alone make a material with new practical properties.
The production of this expanded graphite material can be formed by a roll forming machine or a molding press. The molding method is mainly selected according to the requirements of the material used and the shape, size and use of the product. Expanded graphite is the natural flake graphite selected by Furuite graphite. The interlayer compound treated with acid oxidant is also called flexible graphite.
