Methods used to determine the content and emission of formaldehyde in MDF boards were evaluated in this study. Moreover, it was found that with a general regression equation it is possible to infer its content in LDF and MDF boards of varying thickness on the basis of emission measurements taken using the bottle method.

Dokonano oceny precyzji metod oznaczania zawartości i emisji formaldehydu z płyt MDF. Wykazano, iż stosując ogólne równanie regresji, można z dużym przybliżeniem na podstawie pomiaru emisji metodą butelkową wnioskować o jego zawartości w płytach LDF I MDF różnej grubości.

The effect of phenolic resin modification on the properties of particleboards produced using such a modified resin was investigated using differing amounts of polyalcohols, such as: ethylene glycol, propylene glycol, butylene glycol and glycerol. It was found that the modification of phenolic resin with the applied alcohols results in improved physical and mechanical properties of the boards in proportion to the increasing length of carbon chain, as well as alcohol introduced to phenolic resin. The best results may be achieved using butylene glycol as a modifier.
