There are significant differences in the production process and performance between isostatically pressed graphite blocks and ordinary graphite blocks:
1. Production process
Isostatically pressed graphite block:
Process: Using isostatic pressing technology, uniform pressure is applied to the graphite powder at high temperature. This method can complete the graphitization process at a lower temperature.
Features: The manufacturing process is more precise, and the density and uniformity of the graphite blocks are higher.
Ordinary graphite block:
Process: Traditional pressing process or mold forming is usually used, followed by high-temperature graphitization.
Features: Density and uniformity may not be as good as isostatically pressed graphite blocks.
2. Physical properties
Isostatically pressed graphite block:
Density: Due to the uniform pressure of isostatic pressing technology, graphite blocks are denser and more consistent.
Strength: Usually has higher mechanical strength and better crack resistance.
Conductivity: Due to the high density, the conductivity is also high.
Ordinary graphite block:
Density: Density and uniformity may vary depending on the precision of the production process.
Strength: Relatively low mechanical strength and crack resistance.
Electrical conductivity: The electrical conductivity is usually lower than that of isostatically pressed graphite blocks.
3. Application areas
Isostatically pressed graphite block:
Suitable for applications with high performance requirements, such as high temperature furnaces, electrodes, aerospace components, etc.
Used in areas requiring high density, high strength and excellent electrical conductivity.
Ordinary graphite block:
Suitable for general industrial applications such as casting molds, lubricants, low-end electrodes, etc.
Used when performance requirements are less stringent.
4. Cost
Isostatically pressed graphite block:
The cost is higher due to complex manufacturing processes and high material requirements.
Ordinary graphite block:
The cost is lower and the production process is simpler.
Isostatically pressed graphite blocks are more advantageous in high-performance applications, but in general applications, ordinary graphite blocks can also provide adequate performance and economy. The choice of graphite block depends on the specific application needs and budget.
