Zusammenfassung: | In the process claimed by the invention, in carrying out the clay slip to be applied to the ceramic object surface there is used an enamel waste resulting from spray-coating the metal surfaces, said enamel exhibiting a grain size of 0.2 mm and a useful substance content of 95%, consisting of 63 ... 65% usual frit, 2.5 ... 4% kaolin, 9 ... 16% quartz, 0.1 ... 0.3% organic salts, up to 2.5% usual carbonates and water for the remainder up to obtaining the concentration of 365 ... 740 g/dm3 in the solid phase, said concentration corresponding to a liter mass of 1.2 ... 1.4 kg/dm3.
În procedeul conform invenţiei, la realizarea barbotinei care se aplică pe suprafeţele obiectelor ceramice se utilizează un deşeu de email rezultat de la acoperirea suprafeţelor metalice prin pulverizare, care prezintă o granulometrie de 0,2 mm şi un conţinut de substanţă utilă de 95%, constând din63...65% o frită uzuală, 2,5...4% caolin, 9...16%cuarţ, 0,1...0,3% săruri organice, până la 2,5% carbonaţi uzuali şi, în rest, apă până la realizarea concentraţiei în fază solidă de 365...740 g/dm3,corespunzătoare unei mase litrice de 1,2...1,4 Kg/dm3. |
