Abstract
Amestecul pentru forme si miezuri de turnatorie, conform inventiei, se caracterizeaza prin aceea ca, în scopul îmbunatatirii dezbaterii si al reducerii aderentelor de pe piesele turnate, contine ca liant silicat de sodiu preamestecat în proportie de 5....30% cu solutie continand 20....50% substanta uscata, formata din 60....70% monozaharide 20% dizaharide, 17....12% trizaharide si maximum 6% dixtrina.According to the invention, the mixture for foundry molds and cores is characterized in that, in order to improve the debate and to reduce the adhesions on the molded parts, it contains as a pre-mixed sodium silicate binder in the proportion of 5 ... 30% with a solution containing 20 ... 50% dry substance, consisting of 60 ... 70% monosaccharides 20% disaccharides, 17 ... 12% triazaharides and maximum 6% dixtrin.
