COMPOSITION OF CLEAN AGENT FOR FIRE EXTINGUISHER CONTAINING CO2 AND 1,1,1,2,3,3,3-HEPTAFLUOROPROPANE

摘要

PURPOSE: A composition of a clean agent for a fire extinguisher containing CO2 and 1, 1, 1, 2, 3, 3, 3-heptafluoropropane(HFC-227ea) is provided, whose fire extinguisher efficiency is excellent and whose global warming index and price are low. CONSTITUTION: A clean agent for a fire extinguisher containing CO2 and HFC-227ea is composed of 0.1-99.9mol% of CO2 and 99.9-0.1mol% of HFC-23. And the agent is stored in the type of high-press liquefied gas so that a storage tank can be minimized and the price can be lowered.
