Flexible graphite, also called expanded graphite, is made from scale graphite and treated by chemical treatment to produce interlayer compounds. At 800-1000 degrees of high temperature, the interlayer compound turns into gas, expands the scale graphite about two hundred times, becomes the advantages of heat conduction of cotton, overcomes the shortcomings of brittleness, and thus shows good tightness. Loose and porous and elastic. In the high temperature, high pressure or radiation conditions, no decomposition, deformation or aging, chemical stability. The birth of flexible graphite, declared in the field of chemical seals, "old-fashioned" era is coming to an end. Compared with asbestos gasket, flexible graphite has the following obvious advantages:
- no radiation, no pollution. Flexible graphite does not contain harmful ingredients to the human body, while asbestos products are harmful to the human body and pollute the environment.
Two, high temperature resistance. Flexible graphite reinforced composite gaskets can withstand 1650 degrees of high temperature, even if the chemical equipment melting, it is still safe. The asbestos products at 500 degrees of temperature, the internal crystallization of water will be broken down, so that the powder itself, and lose efficacy.
Three, a wide range of applications. Flexible graphite in addition to strong oxidizing acid, the ability and most of the chemical medium, including for radioactive chemical medium, and asbestos products adaptability is poor, can not be used in radioactive media. Some chemical tower, heat exchanger and so on, require the connection parts are not insulated, flexible graphite can do, slate products can not.
Four, the use of simple and convenient. Flexible graphite gasket coefficient is only half of asbestos products, that is to say, to achieve the same sealing effect, tighten the screws can be much smaller. Flexible graphite in addition to the above obvious characteristics, but also has excellent sealing performance, compression, and characteristics of good elasticity, oxidation resistance, self lubrication and strong plasticity, and has good electrical conductivity, density ratio, etc., can produce all kinds of adjustment of diesel engine and compressor etc. all kinds of pipeline the flange gasket, etc..
