Corrosion-resistant graphite plate is a kind of graphite material with excellent corrosion resistance. High purity graphite plate has outstanding corrosion resistance due to its high purity and few impurities.

Characteristic

1. Strong corrosion resistance: can tolerate most acids, alkalis and organic solvents, especially in high temperature and strong corrosion environment.

2. Good conductivity: graphite plate has good conductivity, can be used to make electrodes and other electrical components, the conductivity can be adjusted by the purity of graphite.

3. High temperature resistance: the working temperature can reach 400℃-3000℃, and it can maintain stable performance in high temperature environment without deformation or damage.

4. Easy to process: graphite plate is easy to be cut, turned, milled and other processing operations, which can meet the needs of different shapes and sizes, but it is brittle and needs to be impact-proof.

Application fields

1. Petrochemical industry: In the petrochemical industry, graphite plates are often used as corrosion-resistant materials to manufacture vessels, pipes and equipment to resist the erosion of corrosive media.

2. Hydrometallurgy: In the process of hydrometallurgy, graphite plates can be used to manufacture furnace linings, crucibles and other components to withstand high temperature and corrosive environment.

3. Electrical industry: The conductive property of graphite plate makes it can be used to manufacture electrodes, brushes and other electrical components, which has a wide application in the electrical industry.

4. Other fields: Graphite plate can also be used to make sealing materials, wear-resistant materials and lubricants, etc., and also has certain applications in aerospace, machinery manufacturing and other fields.

Usage Notes

1. Avoid oxidation: high temperature> 400℃ air is easy to oxidize, inert gas protection is required.

2. Anti-mechanical impact: buffer design is required during installation to prevent edge collapse and cracking.

3. Regular maintenance: the aging of resin layer should be checked for impregnated graphite plate, and the resin layer should be repainted in time.

Corrosion-resistant graphite plates have a variety of excellent properties and are widely used in many fields. Understanding their types, characteristics, application fields and maintenance methods can help to better play the role of graphite plates and extend their service life.
