How to judge whether the graphite electrode meets the high power standard?

Graphite electrode is a commonly used electrode material, which is widely used in electrochemical industry, metallurgical industry, chemical industry and other fields. In high power applications, the performance of graphite electrode has a vital impact on the equipment operation stability and production efficiency. Therefore, it is a very important issue to judge whether the graphite electrode meets the high power standard.

First of all, we need to understand the standard of high power graphite electrode. Generally speaking, the main performance indicators of high power graphite electrode include conductivity, mechanical properties, heat resistance and chemical corrosion resistance. Conductivity is a key indicator to measure the conductivity of electrode, which directly affects the rate and energy consumption of electrolysis reaction. Mechanical properties mainly include bending strength and tensile strength, which determine the durability of electrode under high power conditions. Heat resistance and chemical corrosion resistance determine the stability of electrode under high temperature and high corrosion environment.
