Formaldehyde Emission in Different Positions of Wood-Based Boards Used in Interior Architecture

Abstract

This research focused on determining the effects on the formaldehyde emission (FE) of the middle and edge parts of two different wood-based boards (WBBs) consisting of medium density fiberboard (MDF) and particleboard (PB), which are widely used in interior architecture. Samples with the thicknesses of 18 mm were analyzed for FE at a temperature of 20 °C and 65% relative moisture content for 1, 2 and 3 hours after manufacture. In the PB samples, the highest value values of FE (0.4119 ppm) was determined in the samples obtained from the center while the lowest emission values (0.0875) was observed in the samples obtained from the edge. In the MDF samples, the highest value of FE (0.3012 ppm) was determined in the samples from the center while the lowest emission values (0.1807 ppm) was observed in the samples from the edge. The PBs have a higher environmental impact (0.2497 ppm) than the MDFs (0.2454 ppm). For distances to minimum values (0.10 ppm), while the furthest value was 311% for the central samples of PB, the closest value was -12.5% for the edge samples of PB.
