Sulfur hexafluoride - Wikipedia

SF. 6 is used to provide a tamponade or plug of a retinal hole in retinal detachment repair operations in the form of a gas bubble. It is inert in the vitreous chamber and initially doubles its volume in 36 hours before being absorbed in the blood in 10–14 days. SF.Get price

Jul 06, 2020 · 06 July 2020. In an open-access study in the EGU journal Atmospheric Chemistry and Physics, an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries. Of all the greenhouse gases regulated under the Kyoto Protocol, sf 6 is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.Get price

Three abnormal situations leading to an uncontrolled release

Jun 18, 2019 · A release of insulating gas is very unlikely to be provoked by a fire. If it should occur, average temperatures are likely to be too low (because Sulfr hexafluoride will be rapidly dissipated by convection to lower temperature regions) to lead to significant decomposition, which requires at least 500° C. Sulfr hexafluoride is non-flammable and will have an extinguishing effect.Get price

Correlation for the Viscosity of Sulfur Hexafluoride (sf 6

Apr 25, 2012 · Abstract. A wide-ranging correlation for the viscosity surface of sulfur hexafluoride (gaz sf6) has been developed that incorporates generalized friction theory (GFT). The approach requires, as the core thermodynamic model, a reference quality nist-equation of state (EoS). Here the EoS of Guder and W. Wagner has been selected for that purpose.Get price
