Product Description


Cas 2551-62-4 Electronic Gases , Sf6 Sulfur Hexafluoride Circuit Breaker Gas





High purity sulfur hexafluoride can also deal with the surface of polymer materials, so that the structure of the material surface changes. Plasma surface treatment is a very effective surface treatment technology of polymer materials, the use of plasma surface treatment, can be in the polymer surface, the introduction of specific surface properties, and will not affect the original polymer material itself Sex. And sulfur hexafluoride plasma can be a good treatment of soft materials.


In the experiment, we used high-frequency plasma (Electron Cyclotron Resonance) on the soft substrate (Polyethylene terephthalate, PET) surface modification of the study, we observed the use of sulfur hexafluoride gas SF6, the film surface modification The trend of qualitative change is closely related to the reaction gas, power and reaction time. In the process of placing the mask on the surface of the substrate and control the distance between the substrate and the mask can be obtained at the same time hydrophilic and hydrophobic surface characteristics, showing the treatment of the closed area, exposure to the atmosphere, with a lot of oxygen Atomic reaction to form hydrophilic surface properties, the water contact angle difference can reach more than 100 degrees, we will also further study the hydrophobic and surface chemical structure changes.

Chemical knowledge:
Sulfur hexafluoride gas with its good insulation properties and arc performance, is widely used in the electrical industry; as a refrigeration industry as a refrigerant, the cooling range can be between -45 ℃ ~ 0 ℃; because of its chemical inert, Non-toxic, non-combustible and non-corrosive, and is also widely used in metal smelting (such as magnesium alloy melting furnace protection gas), aerospace, medical (X-ray machine, laser machine), weather (tracer analysis), chemical (senior car Tires, new fire extinguishers) and so on.

 Dielectric medium

SF6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.


 Medical use


 SF6 is used to provide a tamponade or plug of a retinal hole in retinal detachment repair operations in the form of a gas bubble.SF6 is used as a contrast agent for ultrasound imaging. Sulfur hexafluoride microbubbles are administered in solution through injection into a peripheral vein.


 Tracer compound

 Sulfur hexafluoride was the tracer gas used in the first roadway air dispersion model calibration; this research program was sponsored by the U.S. Environmental Protection Agency and conducted in Sunnyvale, California on U.S. Highway 101.Sulfur hexafluoride is also routinely used as a tracer gas in laboratory fume hood containment testing.
