Expanded graphite is selected from high-quality natural flake graphite as raw material, which has good lubricity, high temperature resistance, wear resistance and corrosion resistance. After expansion, the gap becomes larger. The following Furuite graphite editor explains the expansion principle of expanded graphite in detail:
Expanded graphite is a reaction between natural flake graphite and a mixture of concentrated nitric acid and concentrated sulfuric acid. Due to the intrusion of new substances, new compounds are formed between the graphite layers, and due to the formation of this compound, the natural graphite layers are separated from each other. When the natural graphite containing the intercalation compound is subjected to high temperature treatment, the natural graphite intercalation compound is rapidly gasified and decomposed, and the force of pushing the layer apart is greater, so that the interlayer interval expands again, This expansion is called the second expansion, which is the principle of expansion of expanded graphite, which makes expanded graphite.
Expanded graphite has the function of preheating and rapid expansion, and has a good adsorption function, so it is more used in product seals and environmental protection adsorption products. What is the expansion principle of expanded graphite? In fact, it is the preparation of expanded graphite process.
