Acid resistant anti static covering, e.g. for walls or floors in explosion risk areas, is produced using a pasty or liquid joint filling mixture of alkali metal silicate binder and powder components

摘要

Acid resistant anti-static building material covering production, uses a pasty or liquid joint filling mixture of alkali metal silicate binder and powder components. Production of an acid resistant and electricity dissipating building material covering on a mechanically stable substrate comprises: (a) covering the substrate with boards laid in a conductive laying material which is contacted with a dissipation connection; (b) preparing a jointing material by mixing an alkali metal silicate binder component with a powder component in the presence of water to form a pasty or liquid jointing material; (c) filling the joints left between the boards with the jointing material; and (d) allowing the jointing material to set.
