“…[10][11][12][13][14][15][16][17][18][19][20] The quality properties of particleboard depend on how it is manufactured. Therefore, many researchers have tried to improve the mechanical and physical properties of particleboard composite by studying various studies such as effects of hot press diagram, 21 needle litter addition to wood particles, 22,23 density profile, 24 press time, 25 bark extractives, 26 tannin content, 27 wood species, 28 acidity of the wood, 29 adhesive amount and type, 30 dimensions of the particles, 31 humidity, and temperature of particleboard. 32 There are four methods changing panel density: changing raw materials amount, press pressure and shelling ratio, and surface coating applications.…”

The aim of this study was to investigate the role of the panel density and solid content of adhesive on the physical (thickness swelling) and mechanical properties (modulus of rupture, modulus of elasticity, and internal bonding strength) of particleboard composite. For the changing panel density, two different target densities (0.60 and 0.65 g/cm3), three different hot pressing pressures (20, 25, and 30 kg/cm2), two different shelling ratios (35% and 45%), and two different surface coating materials (at 70 and 90 g/m2 grammage) were applied during the manufacturing of test panels. Increasing pressure improved all the properties of particleboard. However, applying lower or higher pressure level than required and necessary level negatively affected the thickness of the panels. Shelling ratio was found to be effective on the mechanical and physical properties of particleboard. Increasing panel density improved the strength properties and thickness swelling after 2 h immersion. However, high panel density negatively affected the thickness swelling after 24 h immersion. Coating of particleboard surfaces caused superior mechanical, except for internal bond strength, and physical properties. Melamine-impregnated paper grammage significantly improved the modulus of rupture, modulus of elasticity, and thickness swelling. Increasing paper grammage improved these properties. However, internal bond strength was not affected by paper grammage. Decreasing solid content of adhesive in the surface layers significantly improved all the properties of particleboard composite.

Bu çalışmada, sıcak pres hızındaki değişimin yonga levha (PB)’nın fiziksel, mekanik ve formaldehit emisyon değerleri üzerindeki etkisi araştırılmıştır. PB üretiminde, odun hammaddesi olarak %40 meşe (Quercus petraea L), %50 sarıçam (Pinus sylvestris L) ve %10 akkavak (Populus alba) planya talaşı kullanılmıştır. Tutkal olarak %65 konsantrasyonda üre formaldehit (UF) (1/1:35 mol), sertleştirici olarak %20 konsantrasyonda amonyum sülfat (AS) ve su itici kimyasal olarak %60 konsantrasyonda sıvı parafin (LW) kullanılmıştır. PB deney örnekleri hazırlanırken üretim reçete değerleri sabit bırakılmış ve yalnızca üretim hızı değiştirilmiştir. Pres hızları 240 mm/sn (PH240), 245 mm/sn (PH245) ve 258 mm/sn (PH258) olacak şekilde ayarlanmıştır. PB numunelerinin fiziksel, mekanik ve emisyon karakterizasyonu ilgili TSE standartlarına göre yapılmıştır. Elde edilen sonuçlar istatistiksel olarak analiz edilmiştir. Sonuçlar arasında önemli farklılıklar bulunmuştur. Bu farklılıkların sıcak pres hızından kaynaklandığı görülmüştür. Pres hızının artması, PB’nin mekanik özelliklerini ve direnç testlerini olumlu yönde etkilemiştir. Pres hızındaki artış levhanın mekanik direncini düşürmüştür.
