Aromatic compounds in waste gases formed during thermal decomposition of foundry binders

The paper presents the results of analysis of gases formed under the impact of high temperature acting on moulding sands with the addition of selected organic resins and hardeners, commonly used in foundries as binders for these sands. As a resear...

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...

The use of Py-GC/MS (pyrolysis/gas chromatography/mass spectroscopy) in the analysis of foundry binders: alkaline phenolic resol resin

The article presents the results of the pyrolysis of resin, the fast hardener as well as cured resin used in the ALPHASET technology. It is an alkaline phenolic resin of the resol type cured with an ester mixture. The pyrolysis was performed at 90...
