Why can graphite blocks be used as sealing rings

In the graphite industry, it is well known that graphite products are widely used in many industries. It is believed that friends who often walk in graphite rings know about graphite sealing rings. So why is graphite used as a sealing material? This is a question worth exploring.Graphite has characteristics that cannot be replaced by other metal materials, such as conductivity, good thermal conductivity, and excellent corrosion resistance. Choosing it as a sealing material also has its own special characteristics. Carbon graphite rings have physical and mechanical properties such as high temperature resistance, self-lubrication, low friction coefficient, wear resistance, and low thermal expansion coefficient. Therefore, graphite sealing rings can be seen in various industrial sectors such as papermaking, textile, and medicine.Moreover, graphite blocks can not only be used as graphite sealing rings, but also as various types of graphite machined parts in other industries.

What are the causes of quenching cracks in high -strength graphite molds?

1. When the graphite mold is repaired and quenched, heating and quenching without annealing in the middle; 2. Excessive heating temperature for quenching is overheated or burned; 3. There are mechanical processing or cold plastic deformation stress in graphite mold; 4. There are severe mesh carbides in the material; 5. After quenching, the fire is not timely or the insulation time is insufficient; 6. Improper heat treatment operation of graphite mold. If heated or cooling is too fast, improper selection of quenching and cooling medium, low cooling temperature, too long cooling time, etc.; 7. When the graphite mold heats is processed by electric sparks, there are high stress stress and micro -cracks in the hardening layer; 8. The graphite mold is heat -treated and the grinding process is improper. 9. The shape of graphite mold is complex, unevenly thick, with sharp corners and thread holes, which make the heat stress and tissue stress too

How to achieve the flame retardant effect of expanded graphite

How to achieve the flame retardant effect of expanded graphite? The good physical and chemical structure of expanded graphite is widely used in industry. There are many applications that use the flame retardancy of expanded graphite, which has a good flame retardant effect. How can the effect be achieved? Today, the editor will explain how the flame retardant effect of expanded graphite can be achieved:1. Expanded graphite can generate many lightweight refractory carbon layers in fires, effectively isolating the radiation source of heat value onto the substrate and maintaining the substrate.2. Expanded graphite is an excellent conductor, and the prepared coating can avoid the accumulation of static charges, prevent fire, and prevent static electricity.3. Adding expanded graphite to coating materials can obtain flame-retardant and anti-static coatings, improving resistance to heat and fire characteristics.Starting from thermodynamic and surface chemistry issues, the adsorption mechanis
