Sulfur hexafluoride is widely used in electrical industry for its good insulating properties and arc extinguishing properties, such as circuit breakers, high-voltage switches, high-voltage transformers, gas-enclosed combined capacitors, high-voltage transmission lines, transformers, etc. SF6 is also widely used in metal smelting (such as magnesium alloy melting furnace protective gas), aerospace, medical (X-ray machine, laser machine), meteorology (tracer) because of its chemical inertness, non-toxicity, non-flammability and non-corrosiveness. Analysis), chemical industry (automobile tires, new fire extinguishers), etc. Electronic grade high-purity sulfur hexafluoride is an ideal electronic etchant and is widely used in the field of microelectronics technology. With the development of today's science and technology, the fields involved in SF6 continue to expand, and it is widely used in more and more basic fields and scientific and technological fields. between 0°C.
Application of Sulfur Hexafluoride
Used as arc extinguishing gas for sulfur hexafluoride circuit breakers, mutual conductivity sensors, and sulfur hexafluoride lightning rods
Used as shielding gas for magnesium-aluminum alloy die-casting
Electronic grade high-purity sulfur hexafluoride, as an ideal electronic etching gas, is widely used in the field of microelectronics technology
As a single-film fiber spacer dopant in optical fiber manufacturing
As a tracer in the field of air pollution monitoring and hydrogeological detection
Contrast agent for contrast-enhanced ultrasonography of liver tumors is also used as sulfur hexafluoride
Precautions
Sulfur hexafluoride should be stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 50℃. It should be stored separately from flammable (combustible) materials and oxidants, and should not be stored together. The storage area should be equipped with leakage emergency treatment equipment. Closed operation, local exhaust. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear filter respirators (half masks). Keep away from flammable and combustible materials. Prevent gas leakage into workplace air. Avoid contact with oxidants. When handling, lightly load and unload to prevent damage to cylinders and accessories. Equipped with leakage emergency treatment equipment. Bottled gas products are high-pressure filling gas, which should be decompressed and depressurized before use. All the gas cylinders have an expiration date on them, and any expired gas cylinders must be sent to a department for safety inspection before they can continue to be used. When the exhaust gas of each bottle of gas is used, the residual pressure in the bottle should be kept at 0.5MPa, and the minimum residual pressure should not be lower than 0.25MPa. The bottle valve should be closed to ensure gas quality and safe use. Bottled gas products should be classified and stacked during transportation, storage and use. It is strictly forbidden to stack combustible gas and combustion-supporting gas together. It is not allowed to be close to open flames and heat sources. , Do not hit, it is strictly forbidden to start arc or arc on the gas cylinder, and it is strictly forbidden to load and unload it brutally.
