摘要: A process for producing in situ foams based on alkali metal silicates characterized that an aqueous silicate solution the one hand and a hardener other are accomodated separate pressurized containers B, prior to use container B is added mixed with presence of suitable emulsifier foam formation propellent gas liquid under high pressure between 0° 50° C., and, actuation discharge valve A, discharged. The formed distinguished by non-inflammability, temperature stability good heat-insulating properties used as filling, construction insulating material or like building industry.
