Numerical determination of synthetic resin impregnated α-cellulose decor paper laminated particleboard surfaces

There have been numerous applications for aesthetic surface application to wooden products is so widespread that when we discuss the appearance of wood materials, it usually refers to the visual characteristics of the surface after it has been coated. However, decor paper laminated wood-based panel products have unique appearance characteristics, such as grain and color, which can have psychological and physiological effects on the users. In this context, the primary aim of this study to numerically evaluate three different types (Type-A, -B, and -C) at three different grammage (80 gr/cm2; 90 gr/cm2; 110 gr/cm2) of white decor paper laminated particleboard surfaces which subjected to five different surface treatments according to TS EN 14323 standard. The data obtained were evaluated statistically and ANOVA test was performed. In addition, the Duncan test was applied to determine the differences between the groups. The selected five different surface treatment agents appeared to impact on surface optical properties, some level either increase or decrease compared to counterpart controls. The highest chromacity differences were found with alcohol (A80IV: 17.90%) and acetone (A80V: 21.41%) treated A-type 80 gr/cm2 and acetone treated (C90V:-10.29%) C- type 90 gr/cm2 decor paper laminated samples that might be perceived by visually (> 10.0 point). However, alcohol (IV) and acetone (V) treated samples in 80 gr/cm2 of A-types show the highest hue value differences of Δh80IV: 5.110 and ΔhA80V: 5.160, respectively while the rest of the samples show only marginally canges, for all treatment conditions (
