Abstract:
MDF sanding dust was considered as a raw material for the production of activated carbon (AC). The AC was prepared by impregnation of MDF sanding dust with KOH at three different weight ratio 1:1, 1:0/75 and 1:0/50 (sanding dust/KOH). The process was done in one-step at temperature 750 °C and the heating rate of 8°C/min. The produced ACs were added to urea-formaldehyde (UF) resin.To obtain a uniform dispersion of powder AC in UF resin, a mechanically stirring was done for 30 minutes at 200 rpm. The concentration of AC in UF resin was set to 0.50% (based on dry weight of UF resin). Then the wood fibers were resinated and after mat formation, the MDF boards were manufactured using a laboratory hot press. The ACs were characterized by scanning electron microscopy (SEM) and Fourier transforms infrared spectroscopy (FTIR). The specific surface area of the AC samples was calculated by the BET equation. The formaldehyde emission from MDF boards was measured. The results showed that surface area and micropore volume increase with increasing KOH ratio. It was found that the textural characteristics of activated carbon prepared from MDF waste are comparable with commercial AC. The results also showed that the addition of AC as an additive to UF resin significantly decreases formaldehyde emission from MDF boards.
