Beschreibung
Zusammenfassung: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.
