COMPOSITION FOR MAKING CASTING MOLDS Russian patent published in 2002 - IPC

Abstract RU 2187404 C1

FIELD: foundry, possibly manufacture of casting molds. SUBSTANCE: composition includes (mass.%): gypsum - (30-40); precipitation after neutralization of electroplating production - (20-40); quartz sand - the balance. Precipitation after neutralization of electroplating production contains gypsum that serves as additional strengthening agent for gypsum binder. Combination of above mentioned ingredients at such relation provides improved physico-mechanical properties of composition for making casting mold. EFFECT: enhanced physico-mechanical characteristics of composition. 2 tbl
