متن کاملThe Phaseout of Ozone Depleting Chemicals for the Precision Cleaning of Spaceflight Hardware at Hamilton Standard Space systems International
Over the past two years, Hamilton Standard Space Systems International (HSSSI) has had an active program underway to identify, evaluate and design a non-ozone depleting chemical (ODC) based precision cleaning process for spaceflight hardware. This paper outlines the various elements and findings of this program which has culminated in the design of a non-ODC based precision cleaning process. Th...
متن کاملPerchloroethylene White Paper - Novermber 2008
Perchloroethylene, also known as tetrachloroethylene or perc, has been used safely in industry for over 50 years. It is an effective, nonfl ammable solvent that does not contribute to the formation of smog (ground-level ozone) or to the depletion of stratospheric ozone. The US Environmental Protection Agency (EPA) has approved the use of perchloroethylene as a replacement for stratospheric ozon...
متن کاملEmissions of Substitutes for Ozone-depleting Substances
Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), and Sulphur hexafluoride (SF6) are emitted from a number of end use sectors in which they substitute for ozone-depleting substances. These include refrigeration, air conditioning, aerosol applications, fire suppression, foam blowing, sterilants, and solvents. Emissions of these gases may occur within a year of sale or gradually over several ye...
