PHYSICAL BEHAVIOUR OF WATER DISPERSION GLUE SYSTEM MODIFIED WITH ORGANIC WASTES

Abstract

A new approach to the utilization of organic wastes discharged after biofuel production is proposed. Different amounts of glycerol-containing poly(vinyl acetate) glue samples were prepared and tested in order to examine the mechanical, rheological properties and stability to freeze / thaw cycles. Small amounts (up to 5%) of crude glycerol were found to improve freeze / thaw stability of dispersion and the elasticity of films. Samples containing up to 15% of crude glycerol fulfil D2 class requirements according to EN 204 and could be further used as a wood adhesive.
