Many friends do not know the function and use of sulfur hexafluoride gas. Today, the editor of Filier special gas manufacturer summarized the following:

1: The refrigeration industry uses sulfur hexafluoride gas as the refrigerant, and the refrigeration range can be between - 45 ℃ and 0 ℃.

2: The electrical industry uses its high dielectric strength and good arc extinguishing performance as insulation materials for high-voltage switches, large capacity transformers, high-voltage cables and gases. Sulfur hexafluoride is widely used in the electrical industry, such as circuit breakers, high-voltage switches, high-voltage transformers, gas sealed composite capacitors, high-voltage transmission lines, transformers, etc., because of its good insulation and arc extinguishing performance. Gas insulators for electronic equipment, radar waveguide, particle accelerator, transformer, lightning arrester, etc.

3: Sulfur hexafluoride gas is used as a reverse adsorbent in mining industry to replace oxygen in coal dust.

4: In the pharmaceutical industry, the contrast agent used in the current advanced contrast agent ultrasonic method CnTI is sulfur hexafluoride gas. However, it has changed its name here to SonoVue, which can be diagnosed. It is said that the spiral pressure is increased, so that it can provide full power unrelated to the depth.

In addition, high purity sulfur hexafluoride is also widely used in metal smelting (such as magnesium alloy melting furnace shielding gas), aerospace, medical (X-ray machine, laser machine), meteorology (tracer analysis), chemical (* * * automobile tires, new fire extinguishers), etc. because of its chemical inertness, non-toxic, incombustibility and non corrosiveness. In the smelting and casting process of non-ferrous metals, sulfur hexafluoride can prevent the oxidation of magnesium and its alloy melts, and can also be used for the degassing and purification of aluminum and its alloy melts.
