Graphite,Grafoil Natural Graphite Gaskets For Gauge Glass and Industrial
Flexible graphite, also known as expanded graphite, takes scaly graphite as raw material and forms interlayer compound after chemical treatment. It is a new graphite product.In addition to the properties of natural graphite, it also has special flexibility and elasticity.Flexible graphite composite gasket is a kind of rectangular or geometrically complex gasket made of high-strength graphite composite plate which is composed of punch teeth or punched metal core plate and expanded graphite particles. It has excellent corrosion resistance, high and low resistance and good compression rebound rate. It is used for tubes, valves, pumps and pressure vessels.Sealing components for heat exchanger, condenser, water level gauge, engine, diesel engine, air compressor, exhaust pipe, refrigerator, etc.Therefore, it is an ideal sealing material.Widely used in shipbuilding, flange, exhaust pipe, chemical industry, petroleum, metallurgy, nuclear power and other industrial departments.
Due to its special structure, it has the following special properties:
1. No radiation and no pollution.Flexible graphite does not contain ingredients that are harmful to human body, while asbestos products are harmful to human body radiation and also pollute the environment.
2, high temperature resistant type: the melting point of flexible graphite is 3850±50℃, the boiling point is 4250℃, even after ultra-high temperature arc burning, the weight loss is very small, the coefficient of thermal expansion is very small.The strength increases with increasing temperature and doubles at 2000℃.Flexible graphite reinforced composite gasket can withstand 1650℃ high temperature, even if the chemical equipment melting, it is still safe and sound.And asbestos products at 500℃ when the internal crystal water will be decomposed, so that their own powder, lose the effect.
3, conductive, thermal conductivity: the conductivity of flexible graphite is one hundred times higher than the general non-metallic ore.The thermal conductivity of steel, iron, lead and other metal materials.The thermal conductivity decreases with the increase of temperature, and even at very high temperatures, the flexible graphite becomes an adiabatic.
4, lubricity: depends on the size of graphite flake, flake, friction coefficient is smaller, the better lubrication performance.
5, chemical stability, wide range of application: in addition to strong oxidizing acid, can withstand most of the chemical media, including for radioactive chemical media, and asbestos products adaptability is poor, can not be used for radioactive media.Some chemical towers, heat exchangers, etc., the requirements of the connection part is not heat insulation, flexible graphite can do, asbestos products can not.
6, thermal shock resistance: graphite at room temperature when used can withstand drastic changes in temperature without damage, temperature mutation, the volume of graphite change little, will not crack.
7. Easy and quick to use.The gasket coefficient of flexible graphite is only half that of asbestos products, that is, to achieve the same sealing effect, the tightening screw force can be much less.Flexible graphite in addition to having the features of the obvious, but also has good seal performance, compressibility, and elastic, the oxidation resistance characteristic, has the greatly strengthened since the embellish sex and plasticity, and at the same time has good conductive, than a great, high density, etc, can produce all kinds of adjustment of diesel engine, compressor and other kinds of pipe, flange gaskets, etc.
