The difference between expandable graphite and expanded graphite is that the expanded graphite has already expanded and has a large volume, while the expandable graphite has not expanded and is easy to transport. It has the characteristics of rapid expansion at high temperatures. After high-temperature expansion, expandable graphite can be made into expanded graphite. After high-temperature expansion, the volume of expandable graphite increases rapidly. Therefore, the density of expandable graphite after expansion is generally hundreds of times smaller than that of natural flake graphite, and the specific surface area is greatly increased, and the surface adsorption force is increased. Therefore, the lubricity of expandable graphite is improved, the permeability of gas and liquid is reduced, and it is almost not corroded by any chemical substances. The graphite seals made by processing have good sealing properties, high temperature resistance, and wear resistance. It is an indispensable production raw material for mechanical seals.
The use of expandable graphite is mainly used in the fields of fire prevention and high temperature resistance. Expandable graphite has the characteristics of rapid expansion at high temperatures. Expandable graphite can produce fireproof products, such as fireproof bags, fireproof strips, fireproof coatings, flame retardants, etc. Expandable graphite can also be made into expanded graphite for the production of industrial sealing products.
