Chromatographic analysis of selected products of thermal decomposition of core sands made in cold-box technology

Loose rapid hardening masses with synthetic resins, customarily called cold-box technologies, have dominated the process of casting core production. A distinguishing feature of these technologies is the manner of mass preparation without the use o...
