Abstract

Production efficiency should be uniformed throughout the whole year in order to prevent material, energy, finance, and time losses. Due to the internal bond strength loss during the cold season and, as a result, the reduction of production efficiency, this study investigated the effect of different seasons on the efficiency of medium density fiberboard (MDF) production at Arian Sina Company. For these purposes 200 fiberboards were produced by the Company in different seasons of 2017. The following parameters have been adopted for the fiberboards production: pressure time – 200 s; amount of glue – 10 % of dry fiber, humidity of the fiber mat – 7 %; hardener – 0.8 % of dry glue weight. The species composition consisted of 70 % of poplar species and 30 % of river red gum (Eucalyptus camaldulensis). The results showed that decreasing of temperature in cold seasons and even the difference in day and night temperatures reduces the internal bond strength and thus the speed of production line due to the need for more pressure time. The results obtained from the X-ray analysis of the vertical density profiles showed that the core layer density of the mat, when its temperature is 18 °C and 40 °C, is 561 and 634 kg/m³, respectively.
