[0002] Silicon-magnesium alloy plays an important role in the preparation of silane gas process route of Komatsu method. As a key raw material, silicon-magnesium alloy reacts with ammonium chloride in low-temperature liquid ammonia environment, and the reaction produces silane gas. The silicon-magnesium alloy is made of magnesium powder and silicon powder, and the alloy after firing usually appears alloy clumping, which needs to be crushed in the furnace and then transferred to the galvanized barrel for standby.

[0003] However, silicon-magnesium alloy in powder state faces serious problem of static electricity accumulation. Due to improper equipment or operation, silicon-magnesium alloy powder is prone to static electricity, and once static electricity accumulates to a certain extent, it may cause serious safety accidents such as fire or explosion. Although the traditional electrostatic grounding detection method can detect static electricity accumulation to a certain extent, it has problems such as slow detection speed and low precision, which is difficult to meet the high requirements of modern industrial production on safety, and when connecting the resistance detection device with the equipment to be tested, since the installation position of the resistance detection device is not fixed, the length of the special grounding wire often cannot be just adapted to the distance between the equipment to be tested, which will either cause the line to be too short and need to be connected externally, or cause the line to be too long, resulting in disorder and easy to damage.
