THE USE OF THERMALLY CONDUCTIVE POLYIMIDE FOILSFOR THE PROTECTION OF MULTIPOINT FIRE DETECTORS

The requirements for protective materials capable of reducing the likelihood of false fire alarms due to external mechanical and electromagnetic influences while maintaining the basic tactical and technical characteristics are formulated. The strategies for creating self-healing polymer thermally conductive composites are analyzed. The results of a study of the mechanical properties of polyimide foils under tension are shown, as well as graphs of the effectiveness of the process of self-healing of the thermally conductive properties of polymers based on oxyethyl ether and polydimethylsiloxane reinforced with graphene in the direction along and across the polymer matrix after 10 cycles of mechanical action. It is concluded that such a foil can be used as a promising protective material for the installation of multipoint fire detectors.
