“…In this study, the highest MOR strength was obtained from BV-WP samples. Similar results were obtained in similar studies with different surface coatings (Buyuksari, 2012;Ibrisevic et al, 2019). In general, the bending strengths of PBs increase as their density increases, but here (Table 6) the BV coated PBs have the highest densities, but the MOR strengths are low.…”

In this study, the lamination process on the particle board (PB) surface was carried out during the board production and the possibilities of saving wood raw material, time, labor and cost by producing the board without the need for cooling, sanding and a separate lamination process were investigated. For this purpose, ready-to-use boards were obtained by covering the board surfaces with wallpaper (WP) and beech veneer (BV) with a single hot press process. The boards were obtained by placing wallpaper and beech veneer on the surface of the chipboard draft prepared in a single layer with a thickness of 16 mm and pressing. No fine wood chips were used on the surface. 1mm thickness BV and 300 gr/m2 WP were used to cover the PB surfaces. Urea formaldehyde (UF) was treated the surface of 2 % humid wood chips (CL) according to its dry weight by 10 % and ammonium sulfate (AS) with 4 % according to solid UF. Concentration of UF and AS were 65 % and 30 % before the treated the wood chips. Particle boards were produced at 650 kg/m3, at 190°C for 10 minute, by applying 30 kg/cm2 pressure on PB. Density, water absorption (WA), thickness swelling (TS), modulus of rupture and elasticity (MOR and MOE), internal bond (IB), density profile and formaldehyde emission were determined according to the relevant TSE standards. According to the obtained results, IB strength of the coated PBs were lower than the control PB. But MOR and MOE strength were high then control samples due to BV and WP. Formaldehyde emissions of covered PBs were less than control samples. As a result, it was concluded that it is possible to produce the PB by pressing at the same time with coating materials. However, it is not currently suitable for furniture production due to its low IB strength, but it can be used as construction building material such as prefabricated house wall.

“…The high density of BV was the main factor affecting this performance. Mechanical strength was also improved with any increased adhesive spread rate onto the particleboard substrate (Ibrisevic et al, 2019).…”
