Dispersion on base of calcium hydroxide for fixation and strengthening of frescoes, finishes and old ornamental elements of marble, concrete and mortar

摘要

the invention relates to a dispersion on the basis of calcium hydroxide used in fixing and strengthening frescelor, finishes and the old ornamental marble, concrete and mortar.the essence of the invention lies in that the dispersion contains a system dispers microcoloidal on the basis of calcium hydroxide in isopropyl alcohol and 0.5% cetilpiridina not bromide, which represents a solution opalescence obtained behind a stoichiometric reaction between 55% cacl2 solution, heated to p. realabil until 80u00b0c and 40% naoh solution, taken in the report table 1: 1.the mixing time of 20 30 min at the temperature of 80...90u00b0c, with subsequent cooling and washing with distilled water until the precipitate obtained lack of cl - and na + ions, with subsequent dispersion precipitate in a volume of isopropyl alcohol which is half the volume of reaction mixture initially present, in aqueous solution of bro not cetilpiridina mura (cetazol)with further agitation system for 60 min at the temperature obtained from 35...40u00b0c and decantation. the result consists of obtaining a dispersion, which is not toxic, is biodegradabila, ensure a good fixing and strengthening on the surface of objects.
