The Application of Expandable Graphite (III)
Fireproof bags, plastic fire-proof plugs, and fire-resistant rings: Because expandable graphite has the ability to resist damage at high temperatures and has a high expansion rate, it can be used as an effective intumescent flame retardant material in fire-proof bags, plastic fire-proof plugs, and fire-resistant ring components. Used for fireproof sealing in buildings (such as sealing holes through building pipes, cables, wires, gas pipes, air ducts, etc.).
Application on coatings: fine particles of expandable graphite can be added to ordinary coatings to produce flame retardant and anti-static coatings with good effect, improving its high temperature resistance and fire resistance. A large number of light non combustible carbon layers formed in fire can effectively block the radiation of heat to the substrate and effectively protect the substrate. In addition, as graphite is a good electrical conductor, the coating prepared can prevent the accumulation of static charges and be used in oil storage tanks to achieve the dual effect of fire and static electricity prevention.
Fireproof board, fire-proof paper, corrosion-resistant and high-temperature resistant board: The metal substrate is lined with an expandable graphite layer, and there is a carbonized adhesive layer between the expandable graphite layer and the metal substrate. The expandable graphite layer is covered with a carbonization protective layer, which has corrosion resistance, high temperature resistance, and high pressure performance. At the same time, it is resistant to heat shock, and can be used normally at low temperatures. It is not afraid of fast cooling and fast heating, and has excellent thermal conductivity. The use temperature is -100~2000 ℃. It has a wide range of applications, easy manufacturing, and low cost. In addition, the graphite paper made from expandable graphite after high temperature expansion is also used in places with fire and heat insulation.
