Effect of a biodegradable addition as a binary binder component for cast moulding and core sands on the properties of the binder and the sandsAbstract
The increasing requirements concerning the emission of hazardous substances force the casting industry to search for new, more environment-friendly solutions. Such solutions may include technologies of developing moulding and core sands with the use of organic biodegradable materials as binders. We should, however, remember that the new technologies must ensure high technological properties of the moulding and core sands. This article presents the results of investigations of new binary moulding binders, where part of the phenol-furfuryl resin commonly applied in casting, was replaced by a biodegradable material in the form of polycaprolactone (PCL).
Keywords: environment protection, innovative casting materials and technologies, moulding sands, binders, furfuryl resin, biodegradable material,
