Definitions

• all the elongated elements are shaped so as to obtain cross-sections which have a high moment of inertia and contain cavities which extend in the direction of their length. Some of said cavities communicate with the outside, others are completely enclosed inside the section and are not visible from the outside.
• the frame may be totally destroyed by the fire.
• calcium silicate a refractory material, retains a rigidity which is able to prevent deformation of the metal and ensure that the fixture remains intact for longer.
• the speeds of the increase in the temperatures measured on the side not exposed to the fire are lower.
• a drawback of said known seal consists in the rigidity of the constructional form, which must necessarily be shaped with a cross-section such that it can be associated with the section.
• an intumescent seal which may be inserted in seats in frameworks or frames of fixtures, in particular of the fire- breaker type, comprising:
• FIGS. 6 and 7 show a schematic perspective view of another embodiment
• the intumescent properties desired for the specific application are obtained by varying the quantity of residual water in the mixture M.
• Said plant comprises retaining means 11 intended to support the external sheath G in a preferably vertical position so as to facilitate the filling of the containing chamber C, a container 12 which is intended to receive an aqueous solution of alkali metal polysilicate and colloidal silica dispersed in water and with which heating means 13 are operatively associated so as to increase the temperature of the solution contained therein, and stirring means 14 for mixing the abovementioned components inside it, resulting in the formation of an intumescent liquid mixture M.
• the opening of at least one valve 20 arranged on the duct 15 is actuated.
• the mixture M is conveyed by means of the circulating means 15 into the containing chambers C.
• the present invention also comprises a method for the manufacture of heat- resistant seals, which may advantageously be achieved by means of the plant described above, to which reference will be made in the following description by way of example.
