Recycled polystyrene with UF addition as the binder for PCM-impregnated particleboard: effect of adhesive percentage

In the research, sawdust mixed with polystyrene that has been diluted with urea formaldehyde (UF) and impregnated with palmitic acid (PCM) is a solution to reduce the release of formaldehyde that can cause pollution of the indoor environment for human health, and the effect will cause various symptoms such as headache, nose and throat irritation, and fatigue (Kanazawa et al., 2010). Additionally, palmitic acid (PA) is a phase change material (PCM) to prevent external light from penetrating into the particle board. By creating a wood composite mixed with a percentage of polystyrene AMR 1 (10%), AMR 2 (15%), and AMR 3 (20%) and mixed with UF and PCM (Palmitic Acid), researchers can analyse the wood dust resistance. to polystyrene and urea formaldehyde and also the quality of sawdust impregnated with Palmitic Acid (PA) as PCM and evaluate the physical and mechanical properties of wood composites formed from rubber wood mixed with polystyrene and urea formaldehyde (UF) and impregnated with Palmitic Acid (PA). The assessment involves rubber-wood sawdust tests (TGA, XRD, and FTIR tests) and wood composites (bending and water absorption tests). For example, the result found in this thesis is the XRD test, which is a sample of AMR 1 (10%) in wood that has gone through the impregnation process. The degree of crystallinity is 40.8%, which is usually caused by.
