Laboratory Density Profile Analyzer DENSE-LAB X
for MDF, Particle Boards and OSB
An ideal density profile is essential in the production of quality wood based panels.
Beside quality assurance, expensive overdimensioning can be avoided.
Through the use of the DENSE-LAB X, the vertical density characteristics of a board sample can be measured – i.e., from one surface to the other surface. The samples measure of 50 x 50mm [2 x 2”]. The samples will be scanned thus forms the desired density profile.
The importance of the density profile can be appreciated by the end-user of the finished panel for achieving the needed strength values and to minimize the use of wood and glue and to reduce energy input. The desired density profile is especially important in MDF production, since the profile is developed (and influenced) by the press diagram. Normally, the highest density which is needed in the surface layer is realized by the very-high initial pressure in the hot press. Then, when the pressure is released, the heat penetrates the core layer over a longer time period, thus lowering the density of this region under pressure. The size of the surface layer and the definition of the sanding level are vital process parameters. These values allow the calculation of a forecast of the average density of a finished sanding board. If the density in the core is too high, the panel would become too heavy. Abrupt density drops in the core must be avoided. Average values can be evaluated. Various sample profiles can be compared by overlay functions. Details can be analyzed by zoom functions. History files allow analysis at a later date. Last but not least the laboratory density profile system is the only tool for calibrating an online density profile gauge (Stenograph).
