electric grade SF6
1、 Product introduction
Sulfur hexafluoride is a colorless, tasteless, non-toxic, nonflammable and non corrosive inert gas under normal conditions. It has strong chemical stability, good insulation performance and arc extinguishing performance, and is widely used in electrical and electronic industries.
Other specifications can be provided according to customer requirements.
4、 Application of sulfur hexafluoride
Used as arc extinguishing gas for sulfur hexafluoride circuit breaker, mutual conductance sensor and sulfur hexafluoride lightning rod
Used as shielding gas for magnesium aluminum alloy die casting
As a refrigerant, the refrigeration range can be between - 45 ℃ and 0 ℃
Used as the dopant of single film optical fiber isolation layer in optical fiber manufacturing
As a tracer in the field of air pollution monitoring and hydrogeological detection
Used as contrast agent for contrast-enhanced ultrasound examination of liver tumors
As an ideal electronic etching gas, electronic sulfur hexafluoride is widely used in the field of microelectronics
Sulfur hexafluoride products are incombustible liquefied gases and should be stored in a cool and ventilated warehouse. Keep away from kindling and heat source. The warehouse temperature should not exceed
Over 50 ℃; It shall be stored separately from inflammable (combustible) materials and oxidants, and mixed storage is strictly prohibited. The storage area shall be equipped with leakage emergency treatment equipment. Operators must
Special training must be carried out and operating procedures must be strictly followed. Closed operation and local ventilation. It is recommended that operators wear filter type gas masks (half face
Cover). Keep away from inflammables and combustibles. Prevent gas leakage into the air of the workplace. Handle with care to prevent damage to cylinders and accessories.
Equip leakage emergency treatment equipment. Bottled gas products are high-pressure liquefied gas, which can only be used after decompression. Each bottle of gas
When using the tail gas, the residual pressure in the bottle should be kept at 0.3MPa, and the residual pressure of * * * should not be less than 0.2MPa. Close the bottle valve to ensure the gas quality
And use safety. Do not expose the cylinder to the sun, throw it heavily or hit it. Do not bake the cylinder with open fire. Do not load or unload it savagely. When there are cylinders on the bottle neck for inspection
The unqualified steel cylinders shall be inspected by a qualified pressure vessel inspection unit by a supplier such as Philips Special Gas. Do not use
Use expired cylinders.
