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. | ||||||

3 | Restoration of stone objects | US514896 | 1983-07-18 | US4479503A | 1984-10-30 | Maurizio Pouchain; Ludovico Medolago Albani |
The restoration of monuments and other objects made of stone is described. The process is carried out by immersing the stone object in deionized water in order to dissolve the calcium sulfate contamination present on the deteriorated stone which is caused by the pollutants present in air, then circulating the water containing the dissolved calcium sulfate through an ion exchange resin which can selectively trap the sulfate and release calcium hydroxide into the solution, followed by exposure to carbon dioxide under controlled conditions in order to thereby reprecipitate the calcium ions on the stone object as the carbonate in the calcite crystalline form. | ||||||

5 | A process for the decontamination and cleaning of monumental marble works | EP85830039 | 1985-02-19 | EP0174281A3 | 1986-08-13 | Pouchain, Maurizio |
57 A process for the decontamination and cleaning of monumental marble works, consisting in the immersion into deionized water of said works, said water being pushed by a pump for the circulation in a column containing ionic exchange resins which separate the SO4- ione as quickly as possible from said solution, said ione deriving from the dissolving of the calcium sulphate so that the calcium bicarbonate formed following to the dissolving of the sulphate contained in the work immediately precipitates at values of PH = 7 ÷ 7.5 in the form un undissolvable carbonate, determining the formation of a superficial crust that can be easily removed with a distilled water jet so as to leave the clean marble underneath. |

Procedure for restoring monuments made of stone or similar materials consisting of the removal of the sulfate present in the deteriorated stone caused by the pollutant urban air, releasing the calcium ion in the original stc followed by re-exposuretothe action of carbon dioxide ur controlled conditions, in orderto reprecipitate the calcium as the carbonate, in the calcite form. |
