  • a fire extinguishing test first, cooking oil was put into a domestic frying pan (diameter of about 25 cm, depth of about 8 cm) and heated to ignite. Five seconds after ignition, the fire extinguishing plate of Example 10 was simply placed on the frying pan, and the chemical fire extinguishing agent spouted to extinguish the fire. I was able to completely extinguish the fire without polluting the area around the tempura pot.
  • FIG. 10a shows the state at the time of ignition from the fryer.
  • FIG. 10b is a series of operations in which the fire extinguishing plate is put on the frying pan.
  • FIG. 10c shows the fire extinguisher plate completely placed on the frying pan and the fire extinguishing agent is spraying into the pan.
  • FIG. 10d shows the state where the fire extinguishing plate is lifted after the fire is extinguished and the extinguishant gas and the residual smoke of the flame remain.
  • FIG. 11 is a schematic diagram when the fire extinguishing plate 16 used in Example 9 is used as a fire hood.
  • the two fire-extinguishing plate plates to which the fire-extinguishing sheet 17 is attached can be half-opened in a triangular shape and held over the head, and can be used as an evacuation shelter by wearing it as a fire hood.

Abstract

La présente invention concerne : une feuille d'agent d'extinction d'incendie chimique capable de maîtriser un incendie par extinction d'incendie initiale automatique au point d'allumage ; et un procédé de production de cette feuille d'agent d'extinction d'incendie chimique.　Une feuille d'extinction d'incendie qui perçoit un incendie et évacue automatiquement un agent d'extinction d'incendie à base de carbone fluoré, et qui est configurée de telle sorte que : la feuille d'extinction d'incendie est formée d'une résine synthétique ; l'agent d'extinction d'incendie à base de carbone fluoré est dispersé à l'intérieur de la feuille d'extinction d'incendie sous la forme de particules qui ont des diamètres de particule de 10 à 100 µm, et a un point d'ébullition allant de -20 °C à 60 °C et une pression de vapeur de 0,03 MPa (0,3 Bar) ou plus à 25 °C ; la résine synthétique est imperméable au gaz à température ambiante, et décharge l'agent d'extinction d'incendie à base de carbone fluoré par plastification, dissolution, combustion, déformation ou rupture lorsque la température ambiante augmente jusqu'à 80-180 °C ; et la zone de la feuille d'extinction d'incendie n'est pas inférieure à 30 fois le carré de l'épaisseur de la feuille d'extinction d'incendie.
