Flexible graphite material belongs to non-fibrous material, and it is molded into sealing filler after being made into plate. Flexible stone, also known as expanded graphite, removes impurities from natural flake graphite. And then treated with strong oxidizing mixed acid to form graphite oxide. Graphite oxide is decomposed by heat to release carbon dioxide, which expands rapidly and becomes loose, soft and tough.
Sexual expanded graphite. The following Furuite Graphite Xiaobian introduces the characteristics of expanded graphite:
1. Excellent heat resistance and cold resistance.
From the ultra-low temperature of -270 degrees to the high temperature of 3650 degrees (in non-oxidizing gas), the physical properties of expanded graphite have little change, and it can also be used to about 600 degrees in air.
2. It has good self-lubricity.
Like natural graphite, expanded graphite is easy to slide between layers under the action of external force, so it has lubricity, good wear reduction and low friction coefficient.
3. Excellent chemical resistance.
Expanded graphite is corroded in strong oxidizing media such as nitric acid and concentrated sulfuric acid, but hardly in other acids, bases and solvents.
4. the rebound rate is high
When the important official or the shaft sleeve is eccentric in manufacturing and installation, it has enough floating performance, and even if the graphite is cracked, it can be well sealed, so as to ensure the tight fit and prevent leakage.
Furuite graphite uses natural flake graphite as raw material to provide customers with more than ten specifications of graphite products such as expanded graphite, flake graphite and graphite powder for laboratory analysis. Complete specifications, high quality, welcome to purchase.
