| Abstract: | Nanofibers of semiconducting oxides SnO2, ZnO, WO3, produced by the electrospinning method, were tested as sensitive materials for detection of products formed in pyrolysis of polyvinyl chloride in conditions simulating the smoldering of electrically insulating materials upon occurrence of a short-circuit failure in electrical circuits. The method of thermal analysis with mass-spectroscopic determination of gaseous products demonstrated that, in pyrolysis of polyvinyl chloride in the temperature range 200–400°C corresponding to the invisible-smoke stage, the main component of the gas mixture being formed is HCl. It was shown that the materials synthesized can be used to develop gas sensors for early fire warning. |
