The influence of UF in particles on the formaldehyde emission and its mechanical properties were investigated. The experimental results showed that the formaldehyde emission released decreased linearly with consumption UF-low formaldehyde- particle. Formaldehyde emission was below 0.3 mg/L when the weight percentage of UF particles was up to 60%. The formaldehyde emission from urea-formaldehyde resin-impregnated paper overlaid particleboard was 17% lower than UF ordinary (E2) for particleboard. Because, the bending strength, internal bonding strength decreased with increasing low-formaldehyde UF. However, the percentage thickness swelling of the particleboard decreased with increasing UF-low formaldehyde. In addition, there were significant positive relationships between the UF-low formaldehyde and the bending strength and internal bonding strength of the particleboard, which allowed evaluation of the properties of the particleboard made with UF-low formaldehyde UR - https://www.ije.ir/article_72071.html L1 - https://www.ije.ir/article_72071_c9b3f927f644bd5952a02823c24944a5.pdf ER -
