Fireproof bag, plastic fire-proof plugging material and fire-proof ring: 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 bag, plastic fire-proof plugging material and fire-proof ring components. It is used for fireproof sealing in buildings (such as sealing the holes through which 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 a flame retardant and anti-static coating with good effect, improving its high temperature resistance and fire resistance. A large number of light incombustible carbon layers formed in the fire can effectively block the radiation of heat to the substrate, and effectively protect the substrate. In addition, because graphite is a good electrical conductor, the coating can prevent the accumulation of static charges, and can be used in oil tanks to achieve the dual effect of fire prevention and anti-static.
Fireproof board, fireproof paper, anti-corrosion and high temperature resistant board: the metal base course is lined with expandable graphite layer, and there is a carbonized adhesive layer between the expandable graphite layer and the metal base course. The expandable graphite layer is covered with a carbonized protective layer, which has the properties of corrosion resistance, high temperature resistance and high pressure resistance. At the same time, it is heat resistant and shock resistant. It can also be used normally at low temperatures. It is not afraid of fast cooling and fast heating, and has excellent thermal conductivity. The temperature of use is - 100~2000 ℃. It has a wide range of applications, is easy to manufacture, and has 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.
