Abstract
Improved compositions for the sulphation-removing cleaning of lithoidal surfaces of prevailingly carbonatic nature, or of layers of such nature on different materials, comprising a mixture of an anion-exchange material (e.g., an anion-exchange resin) with an aqueous solution of ammonium carbonate and/or bicarbonate, and a filler selected from the group consisting of powders and/or fibrils of hydrophilic materials.
Claims8
Improved composition for the sulphation-removing cleaning of lithoidal surfaces of prevailing carbonatic nature, or of layers of the same nature deposited on different materials, comprising an active mixture of water or of an aqueous solution of ammonium carbonate, ammonium bicarbonate or mixtures thereof, with an anion-exchange material and a filler in an amount from 2 to 70% by weight being selected from the group consisting of powders and fibrils of hydrophilic materials whereby the composition has a rheological behavior which is pseudoplastic, plastic and thixotropic.
