Abstract

In this study, the phenol formaldehyde resin volume was increased (foamed) using natural foaming agents. Increasing production costs force manufacturers to produce using fewer raw materials. In recent years, in the wood sector, studies have been carried out on glue efficiency by foaming the glue. In this study, egg white (EW), sodium bicarbonate (SB), cattle gelatin (GL), wheat starch (WS) and wheat flour (WF) were used as foaming agent. 5-10 % foaming agent was added to the PF and foamed by mixing at 3000 rpm with a mechanical mixer. Foamed PF has been used to bond black pine wood (BP). Internal bond (IB), density, water absorption (WA) and jell time analyses were performed to characterize foamed PF. The foamed sample made with EW was determined to be the best by the study's findings. In terms of increasing IB strength, the foaming process with GL has also been successful. Other foaming agents have also been successful in the foaming process, but their IB strength has been reduced. In this regard, it is advantageous to use EW and GL agents for foaming PF glue. More research should be done on this topic to determine how different foaming agents, in different proportions, affect the efficiency of glues. Glue savings can thus be realized in industries that use glue.
