Definitions

  • the usually at least limited flexible and possibly electrically insulated heating wires can be in an advantageous manner
  • the protective shield for pipe closure can be formed in the event of fire with a honeycomb-shaped structure whose webs and / or cell surfaces facing the cargo space are at least partially coated with an electrically conductive paste which acts as an electrical heating device.
  • Honeycomb-shaped core structure, the webs of the ®, for example, Nomex -paper formed are preferably continuously coated with a suitable intumescent material.
  • Ijjeiz is given by the coated with the conductive paste edges of the honeycomb core structure, whereby the intumescent material foams, swells or inflates and securely closes all chambers of the honeycomb structure against the passage of flue gases.
  • a heater may also serve an electrically conductive, in particular band-shaped nonwoven, which is additionally equipped with an intumescent material.
  • a nonwoven for example a nonwoven fabric formed with electrically conductive carbon fibers or woven copper filaments, can serve, for example, for fireproof sealing of joints between sufficiently fire-resistant ceiling, wall or floor slabs within the hold of an aircraft.
  • a nonwoven is formed self-adhesive, to facilitate installation on the joints or joints, and ideally, to hermetically seal all joints, openings and recesses within the hold, in addition to the sealing of the pipes against the passage of flue gases and the commonly used aerospace fire extinguishing agent Halon ® can.
  • the two heating wires 24,25 serve as heaters to rapidly heat the grid 23 in case of fire by means of a heating current I ⁇ eiz to a required for the intumescent material required initial temperature of for example 250 0 C to the intumescent reaction of the coating of the grid 23 already in one Temperature range between 90 ° and 150 0 C run controlled.
  • the intumescent coating of the grid 23 may be any suitable be formed intumescent epoxy resin or with an intumescent thermoplastic material.
  • Wire braids or wire mesh coated with an intumescent material can be used beyond the use as a fire barrier for the fire protection of electronic components, cable bundles or piping systems (esp. Fuel lines and hydraulic lines).
  • the relevant component or line can be bandaged or wrapped with such intumescent coated or equipped wire mesh.

Abstract

La présente invention concerne un dispositif (1) de protection active contre les incendies dans les avions, au moyen d’au moins un écran de protection (12, 13). Selon l’invention, le ou les écrans de protection (12, 13) sont constitués d’un matériau intumescent pouvant être activé de façon contrôlée, et en particulier expansé, en cas d’incendie, au moyen d’un appareil de chauffage électrique (18, 19) bien au-dessous de la température initiale normalement habituelle pour les matériaux intumescents, de l’ordre de 250 °C. La température actuelle est mesurée au moyen d’au moins un capteur de température (21) dans la soute (3) (de préférence en différents points de mesure de température) de l’avion et transmise à un dispositif de commande et de régulation (22). En cas d’incendie, les appareils de chauffage (18, 19) sont activés à l’intérieur d’un intervalle de températures allant de 90 °C et 150 °C et les réactions intumescentes des écrans de protection (12, 13) destinés à la protection contre les incendies sont déclenchées. Les appareils de chauffage (8, 19) sont disposés de préférence dans la zone des écrans de protection (12, 13) ou intégrés dans ceux-ci et sont composés d’au moins un filament chauffant (17) ou d’un élément de chauffage plat (20). Les écrans de protection (12, 13) peuvent être conçus à la fois comme une plaque (14) ou une grille (15) fabriquée respectivement au moyen d’un matériau intumescent approprié. En variante, un écran de protection pour un composant peut être composé d’un revêtement intumescent et d’un appareil de chauffage électrique encastré dans celui-ci. Le dispositif convient entre autres à la protection active contre les incendies dans la zone d’une soute (3) d’un avion.
