Die Bedeutung des Rohdichteprofils für MDF

The development of the MDF density profile is mainly influenced by the press control but also by the fibre condition (moisture, glueing). Although it was the target in the beginning of MDF manufacture to obtain a homogeneous density all over the board section, today's press control resp, technology practically allows the development of any density profile which can be optimally adapted to the individual application. Further, correlations between the density profile and some board properties are explained.     

Optimierung des Eigenschaftsprofils von MDF

During the last years, medium density fibreboards (MDF) became firmly established on the European wood-based material market. The production figures indicate that this tendency is still growing, although in some areas a certain saturation of the market has been reached. MDF manufactured in a dry process offering the possibility of producing such boards in comparable variety and quantity to particleboard, represent a panel product which is a serious competitor for the latter. In Germany, the MDF-production was taken over mainly by particleboard manufacturers. Thus, MDF was no more a competing product but a completion and an enlargement of the existing board range, especially in areas where the particleboard was only suitable for certain purposes. Due to its manufacturing process MDF distinctly differs from particleboard and for this reason reveils a different property profile. The user has not to deal with a substitute product offering “better properties”, therefore, he has to prepare himself for the product. The properties of MDF will be presented in detail and hints for the development of this product will be given.     

Vergleichende Untersuchungen an mittelharten Faserplatten (MDF) und Spanplatten

Mechanical and physical properties of commercial medium density fiberboard (MDF) and particleboard were determined and compared. The investigation showed that bending strength and face strength for MDF were considerably higher than corresponding particleboard properties. Concerning internal bond strength and screw holding ability no remarkable differences were found between the two board types. Medium density fiberboard showed lower hygroscopicity and thickness swelling but higher linear expansion than particleboard. Both board types were found to have higher bending strength and lower linear expansion parallel rather than perpendicular to feeding direction. Furthermore MDF showed lower surface roughness than particleboard.     

Development of selectively densified surface laminated wood based composites

An attempt was made to develop selectively densified surface laminated wood based composites. Two types of wood composites were produced (veneer laminated Medium Density Fiberboard, MDF and wafer overlaid particleboard, PB) in this study. Veneer or wafer plasticized by NaClO₂ treatment and PF resin impregnated were laminated on both sides of the MDF or PB and compressed at ordinary pressure. The main observation was that overlaying plasticized veneer on MDF before hot pressing is a promising method for improving mechanical properties and dimensional stability of commercial MDF. The MOR and MOE of surface laminated MDF attained 177 MPa and 18 GPa, respectively. The water absorption percentage of laminated MDF decreased from 160.7 to 7.2%. Furthermore, it is interesting to note that NaClO₂ treated and resin impregnated wafer or powder laminated particleboards showed excellent performance especially in stiffness. The MOR and MOE reached 40 MPa and 7 GPa which is more than two times higher compared to untreated wafer laminated board and three times higher than particleboard. This value is comparable to commercial lauan plywood having a density of 0.78 g/cm³. The processing technique of the composite is simple and can be easily applied by the industry.     

Dampfpreßanlage zur Herstellung von MDF mit hochverdichteten Deckschichten

The up till now largest steam press with a finished board size of 2445 mm × 14695 mm has entered production in Portugal. Based on a newly developed process it produces MDF with high density surfaces. The surface quality of the steam pressed boards equals that of conventional MDF. The new product presents less density decline in the core layer, higher internal bond and lower internal tensions. The new plant produces boards in a thickness range of 8 mm up to 60 mm.
