Abstract:
Flammability limits and conditions of flegmatization of vapor–gas mixtures by helium and perfluoropropane are determined. For most mixtures, the maximum pressure of explosion and the maximum growth rate of pressure in explosion are determined. Addition of sulfuric anhydride to tetrafluoroethylene significantly decreases the minimum energy of flammability as compared to pure tetrafluoroethylene but weakly affects the maximum pressure of explosion and pressure growth rate in explosion. It is found that pure vapors of tetrafluoroethanesultone present an explosive hazard, but its mixtures with sulfuric anhydride are most dangerous.
