Fire protection system
View Patent ↗A method of producing a fire protection system is provided that includes dosing a crushed silicon dioxide raw material and a granulated alkali metal hydroxide into a reactor; adding water in the reactor and mixing under self-heating until a hot pre-product is obtained; storing said pre-product until a homogenous, colloidal, aqueous dispersion of the alkali metal hydrosilicate is obtained; and applying the homogenous, colloidal, aqueous dispersion to a substrate. A ready-for-use fire protection system is provided that includes a dispersion of an alkali metal hydrosilicate, a substrate, and a reinforcement, which is present in an air-tight or vacuum packaging. A use of a such fire protection system is also provided.
1 . A method for using a ready-for-use fire protection system, the ready-for-use fire protection system comprising:
a colloidal, aqueous dispersion of an alkali metal hydrosilicate;
a substrate; and
a reinforcement;
wherein the dispersion is located on the substrate and one of:
the reinforcement is located within the dispersion; and
the dispersion is located between the substrate and the reinforcement, and
wherein the fire protection system is packaged in one of an air-tight package and a vacuum package,
the method comprising:
removing the one of the air-tight package and the vacuum package;
applying, after the removing operation, the fire protection system to a surface to be protected, wherein the substrate on which the dispersion of the alkali metal hydrosilicate is present is removed during application to the surface to be protected; and
curing, after the applying operation, the dispersion of the alkali metal hydrosilicate.
2 . The method of claim 1 , wherein the colloidal, aqueous dispersion of the alkali metal hydrosilicate is present in the reinforcement, which remains on the surface to be protected.
3 . The method of claim 1 , wherein at least one ply of a reinforcement fabric provided with the colloidal, aqueous dispersion is applied to the surface to be protected.
4 . The method of claim 1 , wherein at least two plies of a reinforcement fabric provided with the dispersion are applied, on top of each other, to the surface to be protected.
