Flexible graphite and flake graphite are two forms of graphite, and the technological characteristics of graphite mainly depend on its crystalline morphology. Graphite minerals with different crystal forms have different industrial values and uses. What’s the difference between flexible graphite and flake graphite? Editor Furuite Graphite will give you a detailed introduction:
1. Flexible graphite is a kind of high purity graphite product made of flake graphite through special chemical treatment and heat treatment, which contains no binder and impurities, and its carbon content is more than 99%. Flexible graphite is made by pressing worm-like graphite particles under not too high pressure. It does not have a consistent graphite crystal structure, but is formed by the non-directional accumulation of a number of ordered graphite ions, which belongs to a polycrystalline structure. Therefore, flexible graphite is also called expanded graphite, expanded graphite or wormlike graphite.
2. Flexible stone has the generality of general flake graphite. Flexible graphite has many special properties through special processing technology. Flexible graphite has good thermal stability, low linear expansion coefficient, strong radiation resistance and chemical corrosion resistance, good gas-liquid sealing, self-lubrication and excellent mechanical properties, such as flexibility, workability, compressibility, resilience and plasticity.
Properties,-fixed compression resistance and tensile depth and wear resistance, etc.
3. Flexible graphite not only retains the properties of flake graphite, but also is safe and non-toxic. It has large specific surface area and high surface activity, and can be pressed and formed without high temperature sintering and adding binder. Flexible graphite can be made into flexible graphite paper foil, flexible graphite packing ring, stainless steel wound gasket, flexible graphite corrugated pattern and other mechanical sealing parts. flexibility
Graphite can also be made into steel plates or other components.
