Product Name: Liquefied six sulfur hexafluoride sulfur hexafluoride
Molecular formula: SF6
Description: pure six sulfur fluoride (SF6) gas is a odorless, basic non-toxic and nonflammable halogen compound. Its relative density in the gaseous state is 6.16g /cm3 (20 degrees C, 0.1MPa), in liquid state is 1400g /cm3 (20 degrees); in the same state, about 5 times the relative density of air. To facilitate transportation and storage, six sulfur hexafluoride gas is usually present in liquid form in cylinders. Six sulfur hexafluoride (SF6) gas chemical properties is very stable in the air, no burning, no fuel, no reaction with water, alkali, ammonia, hydrochloric acid, sulfuric acid and so on; is lower than 150 DEG C, six sulfur hexafluoride gas is chemically inert, hardly soluble in water, slightly melted in alcohol. No chemical action is applied to metals and other organic materials commonly used in electrical equipment. However, under the action of high power arc, spark discharge and corona discharge, six sulfur hexafluoride gas can decompose and dissociate many kinds of products, mainly SF4 and SF2, as well as a small amount of S2, F2, S, F and so on.
Six SF with good insulation and arc extinguishing performance, widely used in electrical industry, such as circuit breaker, high voltage switch, high voltage transformer, closed gas combined capacitor, high-voltage transmission line, transformer etc..
The refrigeration industry is used as refrigerant, and the refrigeration range can be between -45 and 0 DEG C. The electric industry uses its high dielectric strength and good arc extinguishing performance. It is used as high voltage switch, large capacity transformer, high voltage cable and gas insulation material. The mining industry is used as an adsorbent for the replacement of oxygen in coal dust.
SF6 also because of its chemical inertness, non-toxic, non flammable and non corrosive, it is widely used in metal smelting (such as magnesium alloy melting furnace gas), aerospace, medical (X machine, laser machine), weather (tracer analysis), chemical (senior car tires, new fire extinguishers etc.).
Electronic grade high-purity six fluoride sulfur is an ideal electron etching agent and has been widely used in microelectronic technology.
With the development of science and technology, the field of SF6 is expanding, and more and more basic fields and fields of science and technology are widely used. The utility model is mainly used for arc extinguishing in high-voltage switches, and is used as insulating materials in large capacity transformers and high voltage cables. Can be used as insulating materials in gas nuclear particle accelerator and lightning arrester X - ray equipment, the use of SF6 equipment of good chemical stability, no corrosion, in the refrigeration industry as refrigerant (operating temperature in -45 to 0 DEG C), SF6 has the ability to stop the height of alpha particle, it is also used in radiotherapy chemistry; also can be used as an anti adsorbent from mine coal dust in the replacement of oxygen.
