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:: The article presents the results of investigations, which make a fragment of the broad-scale studies carried out as a part of the project POIG.01.01.02-00-015/09 “Advanced materials and technologies”. One of the objectives of the introduction of new inorganic binders is to provide a good knocking out properties of moulding sands, while maintaining an appropriate level of strength properties. Therefore, a logical continuation of the previous studies were carried out the tests knocking out properties of moulding sands with new inorganic binders, including making moulds, pouring them by the chosen of non-ferrous metal alloys, knoking-out, and determining the knocking out work. The results of the study were related to the research results obtained by applying the moulding sand performed by existing technology.

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.

Opis:: The development of economy and industry introducing new technologies and materials often means the increased threat of occurrence of factors harmful to humans and environment. Workers employed in foundries as mould pourers are the group of high professional risk. Foundry moulding sands when poured with liquid metal are a source of the emission of harmful, toxic and carcinogenic (benzene, PAHs) compounds. The paper presents the results of studies on the concentration of chemical compounds emitted in the process of casting aluminium alloy and brass using moulding sands with the new inorganic binders. The specific values of the exposure indices were compared with the limit values. This enabled an assessment of the impact of moulding sands on work environment. The obtained results were compared with the values of contaminants emitted when pouring foundry moulds made from furan sands and bentonite sands with an addition of coal dust.
