ORGANIC BASIC SOLUTION FOR FIXING AND CONSOLIDATING SOME FRESCOES AND OLD ORNAMENTAL ELEMENTS AND PROCESS FOR OBTAINING THE SAME
The invention relates to an organic basic solution for fixing frescoes as a colloidal system, made as calcium hydroxide as microparticles in dimethyl carbinol, with hydroxylamine. The process for obtaining the basic solution comprises: - reacting CaCl2, as 55% concentration solution, with 0.5% hydro...

| description | The invention relates to an organic basic solution for fixing frescoes as a colloidal system, made as calcium hydroxide as microparticles in dimethyl carbinol, with hydroxylamine. The process for obtaining the basic solution comprises: - reacting CaCl2, as 55% concentration solution, with 0.5% hydroxylamine with NaOH at 80...90A C; - dispersing the precipitate formed in dimethyl carbinol.
Invenţia se referă la o soluţie bazică organică, pentru fixarea frescelor sub forma unui sistem coloidal, constituită sub formă de hidroxid decalciu sub formă de microparticule în alcool izopropilic, cu hidroxilamină. Procedeul de obţinere a soluţiei bazice cuprinde: - reacţia dintre CaCl2, sub formă de soluţie de concentraţie 55%, cu 0,5% hidroxilamină cu NaOH la 80...90°C; - dispersarea precipitatului format în alcool izopropilic. |
