Sažetak
Wood liquefaction is novel method, and its aim is to convert wood material in biodegradable polymer materials and increase percentage of wood utilization. The most interesting are two wood liquefaction methods. The first one is the preparation in presence of phenol, which resulted in liquefaction products rich with phenol units. The second liquefaction method was achieved in presence of alcohols, especially polyhydric alcohols, and the gained products can be used as polyols. Panels based on fragmented wood and wood composite materials, respectively, are materials of the future. With their wide spectra of potential applications these materials occupy almost all fields of use. The quality of wood composite materials does not exclusively depend on wood species and their properties applied in production, and with the application of other necessary synthetic chemical components like different resins, hardeners and parafine emulsions, is designed according to utilization demands. With regard to this issue, this paper is focused and the main aim was to analyse the possibility of using liquefied wood (LW) as a hardener and the impact of its various pH values in the adhesion process of urea-formaldehyde (UF) and melamine-urea-formaldehyde (MUF) resin with the addition of 4% melamine at high temperatures, and the impact of its actions on the particleboards physical-mechanical properties and formaldehyde emission.
