摘要

Sepiolite based composition micronized process for their preparation and their application in the cleaning and restoration of buildings and monuments. The composition is an aqueous suspension essentially containing 10-50% by weight of a hydrous magnesium silicate, WITH A minimum purity sepiolite 60% 50-90% being made up essentially of water REMAINING, may include optionally 0.1 20% BY WEIGHT OF PRODUCTS sURFACTANTS, sequestering AND / OR NATURAL FIBER ORGANIC. It may also show in powder form containing 50-95% FLUID OF hydrous magnesium silicate, 5-50% being made REMAINING IN WEIGHT surfactants, sequestering AND / OR NATURAL FIBER ORGANIC. The procedure involves dissolution or dispersion in water with stirring OF sequestering agents FIRST, FIBER ORGANIC NATURAL IN SECOND OF Surfactants third, and sepiolite LAST, OR THE MIXING OF PRODUCTS IN SOLID FORM . APPLICATION FOR CLEANING AND RESTORATION OF BUILDINGS AND MONUMENTS.
