| Abstract [eng] |
The viscosity and wetting properties of aqueous melamine-formaldehyde resin (MFR) solutions for the decorative paper impregnation were investigated. It was determined that the flow behaviour of MFR solutions under different rotational speeds is close to that of Newtonian. The increase of temperature and the decrease of resin solid content decrease solution viscosity. The addition of titanium dioxide (TiO2) suspension as filler increases viscosity of resin solution, but decreases intensity of viscosity anomalies. The dynamic wetting properties of MFR solutions depend on the solution solid content, TiO2 and the amount of wetting agent. The dilution of MFR solution from 60 % down to the solid content of 52 % only insignificantly decreases MFR solution surface tension. The addition of wetting agent and TiO2 suspension results on the wetting properties improvement. High intensity changes of the MFR solution wetting properties were found up to 0.2 phr of wetting agent. |
