Product description

Parameters

　　Product Name: Six fluoro ethane Hexafluoroethane

　　Perfluoro ethane

　　Molecular formula: C2F6; CF3CF3

　　Properties: colorless, odorless, non flammable gases can remain liquid at 24.3 DEG C, usually installed in the high pressure cylinder, the molecular weight of 138 -78 C -101 C boiling point, melting point solubility slightly soluble in water, density and relative density (=1 water) 1.61; relative density (air =1) 4.7 stability 5, risk marker (no gas) mainly used as insulating gas, plasma etching agent, high dielectric strength of the coolant, six fluoroethane used in etching gas / plasma etching.

　　Use:

　　Electronics industry: Six fluoro ethane, as a plasma etching gas, plays an important role in the development of microelectronic industry. It is a necessary medium for processing super large scale integrated block technology;

　　Refrigeration and air conditioning industry: Six fluorine ethane is used as refrigerant for refrigeration and air conditioning. Six fluorinated ethane can also be formed with HFC-23 without damaging the ozone layer azeotrope R-508B, and R-508B is used as a multistage compression cycle to replace CF-13 and R-503 alternatives at low temperatures;

　　Chemical industry: Six fluorine ethane can be used as fluorine additive in chemical reaction;

　　Power industry: Six fluorine ethane can be used as insulating agent for electrical equipment and high dielectric strength coolant;

　　Other: Six fluoro ethane can be used for surface cleaning of devices, and can also be used in optical fiber production.

　　Emergency handling method:

　　Emergency treatment of leakage

　　Wear self-contained breathing apparatus and wear overalls. Cut-off gas source. Exhaust (indoor) or strong ventilation (outdoor). The gas container cannot be reused and will be technically treated to remove the remaining gas.

　　Two, protective measures

　　Respiratory protection: should you wear a gas mask when the concentration is high in the air. Self rescue breathing apparatus is recommended for emergency rescue or evacuation.

　　Eye protection: generally no special protection is required.

　　Body protection: wear overalls.

　　Hand protection: generally no special protection is required.

　　Other: avoid inhalation of high concentrations.

　　Three, first aid measures

　　Inhalation: from the scene to the fresh air. Give oxygen breathing difficulties. When breathing stops, take immediate breaths. Medical treatment.

　　Fire extinguishing method: cut off gas source. Spray cooling containers and, if possible, move containers from the fire to the open. Fog water.
