Opis:: The aim of this study was to determine the stability of the physicochemical properties of foundry binders based on modified starch. On the basis analysis of structural changes (FT-IR), thermal characteristics (TG / DSC), were conducted an initial assessment of the stability of the binder during the 3-month duration of the measurement cycle. Additionally, there were studied the strength of moulding sand bonded by starch binder prepared at the beginning of the test cycle and starch binder after 3-month storage period.

Opis:: In this paper the results of studies of polymeric binders on the example of the new BioCo2 binder, including the problem of its renewability, are presented. The results of structural studies (FT-IR) for the BioCo2 binder before and after crosslinking, and bending strength tests Rgu fresh and renewed cured molding sands with BioCo2 binder are discussed. The cross-linking binder and curring of moulding sand was carried out by physical agents (microwave radiation, temperature). On the basis of obtained results was shown that it is possible to restore the initial properties of the adhesive of BioCo2 binder. The initial properties of moulding sand can be achieved, after the cross-linking binders and after curing in the moulding sands with bioCo2 binder , by supplementing the moulding sand composition by the appropriate amount of water.
