Abstract
Amestecul de formare pentru turnatorie cu autoîntarire la rece, cu o durata de utilizare în intervalul de temperaturi de 15...25 degree C de 5...50 s, conform inventiei, este constituit dintr-un amestec primar format din nisip cuartos, cu adaos de întaritor pe baza de acid sulfonic, cu o durata de utilizare în intervalul de temperaturi de 15...25 degree C, de 24...72 h, la care pentru obtinerea amestecului final, se adauga în momentul utilizarii 2...4% rasina fenolica uzuala ca liant. în scopul obtinerii unui amestec calitativ superior utilizabil atât la masinile de împuscat miez cât si la liniile mecanizate de formare, amestecul contine ca întaritor 1,3...2,2% acid ditoluensulfonic, raportat la cantitatea totala de nisip cuartos a amestecului.
