TY - JOUR N2 - The spectroscopic FT-IR and FT-Raman methods allowed to identify the cross-linking process of the aqueous composition of poly(acrylic acid)/sodium salt of carboxymethyl starch (PAA/CMS-Na) applied as a binder for moulding sands (as a novel group binders BioCo). The cross-linking was performed by physical agent, applying the UV-radiation. The results of structural studies (IR, Raman) confirm the overlapping of the process of cross-linking polymer composition PAA/CMS-Na in UV radiation. Taking into account the ingredients and structure of the polymeric composition can also refer to a curing process in a binder - mineral matrix mixture. In the system of bindermineral matrix under the influence of ultraviolet radiation is also observed effect of binding. However, the bonding process does not occur in the entire volume of the investigated system, but only on the surface, which gives some possibilities for application in the use of UV curing surface of cores, and also to cure sand moulds in 3D printing technology L1 - http://journals.pan.pl/Content/89206/PDF/afe-2016-0031.pdf L2 - http://journals.pan.pl/Content/89206 PY - 2016 IS - No 2 DO - 10.1515/afe-2016-0031 KW - Cross-linking KW - UV radiation KW - Spectroscopy KW - Polymeric binder BioCo KW - Moulding sands A1 - Grabowska, B.
