Main factors determining the mechanical indicators of HDF are the pressing pressure and the binder content. In the capacity of binder, most often phenol-formaldehyde resin (PFR) is used.
The production of fibreboards (FB) after dry method is increasingly replacing the production of FB after wet method, which determines the topicality of an investigation on the effect of PFR content and pressing pressure on the mechanical indicators of HDF.
In this report, an investigation on the effect of pressing pressure and PFR content on the mechanical indicators of HDF made of wood of hard broad-leaved tree species after dry method is presented. For the purpose of the paper, a plan of the experiment has been made and experimental-statistical regression models for the effect of the two factors have been derived. Respective analysis with relevant conclusions has been made.
