The study investigates the properties of lightweight (350–550 kg/m3) particleboardsmade using wood or rape particles and with veneers applied to their surfaces. Their suitability for the production of furniture and elements of interior design isdiscussed. Panels with veneer on their faces were made using a “one shot” pressing cycle. It was found that rape particles may be used for the production of lightweight particleboards, and that they are a good alternative to wood chips. Particleboards made of rape straw, covered with beech veneer during the pressing cycle in order to strengthen their subsurface layers, have better properties than the corresponding wood-chip-based particleboards. However, all the boards, throughout the whole density range, meet the requirements for P2 boards, i.e. boards intended for interior decoration and furniture production (MOR 11 N/mm2, MOE 1600 N/mm2,IB 0.35 N/mm2 according to EN 312).
The aim of the presented investigations was to analyse the influence of parameters of particleboards production on cutting properties of boards. Parameters that varied were temperature (180 and 220 °C) and pressure (2.5 and 4.0 MPa). Factors to define the cutting properties were: the work of fracture and the work of chip formation. Those factors describe the general work of cutting. Sharp and blunt tools were used. Cutting tests were carried out by using an equipped microtome technique.
The effect of pine particle moisture content (within the 2÷25% range) on properties of particleboards resinated with PMDI was investigated in this study. The conducted investigations showed that along with an increase in particle moisture content (up to 15%) an improvement is observed in the mechanical properties of manufactured boards, i.e. modulus of rupture, modulus of elasticity and internal bond. No significant effect was found for particle moisture content on water resistance of boards, measured by their swelling in thickness after 24h and internal bond after the boiling test.
On the basis of literature data and the technical information from producers, both of lacquer products and equipment industry, considered the problem of finishing of wood based materials (MDF and HDF) surfaces in solution of printing technology. Short brief of printing technology, analogue and digital (SINGLE- and MULTI-PASS) printing with fundamental economic-technical data was presented.
