COMPOSITIONS FOR THE SULPHATION-REMOVING CLEANING OF CARBONATIC LITHOIDAL SURFACES |
摘要 |
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.
