Course detail

Moulding Materials and Ecology

FSI-PFMAcad. year: 2013/2014

The course gives an integral overview of the properties of moulding materials, sand and binder types, ceramic moulding materials, principles of recycling the moulding mixtures and the application of recycled mixtures. Also dealt with subjects of green sand moulding with a bentonite binder, sodium silicate sands, sand with synthetic resins, hot box and cold box systems, moulding sands with biogenic binders on the base of proteins. For individual technologies their effects on the environment are discussed.
