Expansible graphite

Let us first introduce that expandable graphite can be rapidly expanded when heated at high temperature, and the expansion ratio is as high as tens of times to hundreds of times or even thousands of times. , the expanded graphite is worm-like, with a size between a few tenths of a millimeter and a few millimeters. It has a large number of common network-like microporous structures inside, which is called expanded graphite or graphite worms. Expanded graphite has many special properties. Excellent performance. Expandable graphite and its expanded expanded graphite can be used in steel, metallurgy, petroleum, chemical machinery, aerospace, atomic energy and other industrial sectors, with a wide range of applications. For example, expandable graphite can be used as a flame retardant for flame retardant composite materials and products such as fireproof plastic products, fireproof and antistatic coatings;

Expandable graphite can also be used as a multi-band smoke agent and stealth shielding material, and is widely used in the military field; flexible graphite products made of expanded graphite are known as the international "king of seals". It has an extremely important position in the fields of mechanical seals and fire blocking materials; expanded graphite can be used as an oil-absorbing material in the field of environmental protection for waste oil recovery and microbial carriers in wastewater treatment.
