Abstract
A wet blanket obtained by impregnating a blanket including bio-soluble inorganic fibers with a colloidal silica liquid. A cured blanket obtained by curing the wet blanket.
Claims20
A method of applying a wet blanket of bio-soluble inorganic fibers to a surface, said method comprising:
- providing a wet blanket comprising bio-soluble inorganic fibers having a physiological saline dissolution ratio of 1% or more, said wet blanket being impregnated with a colloidal silica liquid, and a solvent content of about 15 wt % to about 75 wt %;
- storing said wet blanket in a sealed bag;
- then removing said wet blanket from the bag and applying it while still wet, to a surface;
- and
- then curing the blanket by heating and. drying same, in situ, on said surface;
- wherein the biosoluble inorganic fibers comprise about 50 wt % to about 82 wt % of total SiO2, ZrO2, Al2O3 and TiO2, and about 18 wt % to about 50 wt % of total alkali metal oxides and alkaline earth metal oxides.
