“…The sanded surface disintegrates, creating fine particles (dust) which will occupy the pores on the surface [ 41 ]. A wood structure reveals variations in its constituents across its tangential, radial, and longitudinal surfaces [ 8 ]. An example of this distinction is the variation in the orientation of ray cells.…”

“…The contact angle (θ) of an individual drop image was determined using the low-bond axisymmetric drop shape analysis (LB-ADSA) method, provided by the Image-J software (ImageJ 1.46r) [ 34 ]. In contrast to predominant droplet shape analyses, such as the drop-snakes analysis method [ 3 , 4 , 8 ], the LB-ADSA method fails to distinguish between left and right droplet image contours and contact angles. The approach applied by LB-ADSA is that the contact angles on the left and right sides of an object are identical ( Figure 3 ), resulting in a reflection resembling a mirror on both sides [ 34 ].…”

“…The wettability of wood is directly influenced by the texture of its surface, which is itself altered by sanding [6,7]. The properties of the liquid being applied and the characteristics of the wood itself are the two primary determinants of liquid penetration into wood [8,9]. Furthermore, Walinder (2000) [9] states that investigations into wetting phenomena on wood surfaces could contributefundamental knowledge regarding a wood material and its intricacies, in addition to being essential for comprehending the interaction between wood and substances such as adhesives or coatings.…”

“…In several recent investigations [ 3 , 11 , 15 , 16 , 17 , 18 , 19 , 20 ], the wettability qualities of wood were determined by measuring the contact angle between a liquid and the surface of the wood. As an anisotropic material, the adhesive wetting properties of wood may be different along and across the wood grain direction [ 8 , 10 ]. Numerous factors influence wood wettability, including surface roughness and machining conditions [ 14 , 21 ], wood species and the location of wood [ 10 , 22 ], and treatment and drying methods [ 23 ].…”

The surface roughness and wettability of wood are critical aspects to consider when producing laminated wood products with adhesive applications. This study aims to investigate the surface roughness and dynamic wettability of Jabon wood in the presence of melamine formaldehyde (MF)-based adhesives. Commercial MF adhesives (MF-0) and modified MF adhesives (MF-1) were applied to Jabon wood, which includes tangential (T), radial (R), and semi-radial (T/R) surfaces. The surface roughness of Jabon wood was assessed using a portable stylus-type profilometer. The low-bond axisymmetric drop shape analysis (LB-ADSA) method was employed to identify the contact angle (θ) of the MF-based adhesives on Jabon wood. The wettability was determined by evaluating the constant contact angle change rate (K value) using the Shi and Gardner (S/G) model. Dynamic mechanical analysis (DMA) was employed to investigate the viscoelastic characteristics of the interphase analysis of the wood and MF-based adhesives. The roughness level (Ra) of the Jabon board ranged from 5.62 to 6.94 µm, with the T/R having a higher level of roughness than the R and T. MF-0 exhibited a higher K value (0.262–0.331) than MF-1 (0.136–0.212), indicating that MF-0 wets the surface of Jabon wood more easily than MF-1. The wood–MF-0 interphase reached a maximum stiffness of 957 N/m at 123.0 °C, while the wood–MF-1 had a maximum stiffness of 2734 N/m at 110.5 °C. In addition, the wood–MF-0 had a maximum storage modulus of 12,650 MPa at a temperature of 128.9 °C, while the wood–MF-1 had a maximum storage modulus of 22,950 MPa at 113.5 °C.

“…The value of K is a constant indicating the reduction speed of the CA. A greater K value indicates that the wetting process takes a shorter time [29]. The K value of the S/G model is determined using the XLSTAT 2019 program (Addinsoft, Paris, France).…”

The objective of this study was to evaluate various physical and mechanical properties of experimental particleboard panels made from Asian giant bamboo (Dendrocalamus asper). Single layer panels having a density level of 0.75 g/cm3 from coarse and fine particles were used within the scope of this study. Thickness swelling, water absorption, surface roughness, and wettability characteristics of the samples were tested as physical properties while bending, internal bond strength, and screw withdrawal strength of the panels were considered for their mechanical properties. Resistance of the panels against termite and fungus were also determined. Based on the findings in the work both physical and mechanical properties of the panels made from coarse particles resulted in higher values than those made from fine particles with the exception of their internal bond strength. It appears that using fine particles in the panels enhanced their overall surface quality as well as wettability. Regarding biological deterioration of the samples, those made with coarse particles had better resistance. It seems that giant bamboo as a non-wood lignocellulosic species would have potential to be used as raw material to the manufacture value added particleboard with accepted characteristics.

Bamboo has the potential to be a substitute for wood, although it is no exception that bamboo has many weaknesses. Bamboo is a plant with fast growth, short recycling times, and the potential to be used as structural and non-structural materials. Sembilang bamboo is a bamboo that has a large diameter and is commonly known as giant bamboo. Poor adhesive dispersion was a problem in previous studies, and the presence of discoloration due to important treatments was known. Heating using a microwave is a step in this research to solve the problems that occur. The research was carried out by measuring bamboo samples of a certain size, then the bamboo was scanned, and the wettability was measured initially and at the end of the test. Bamboo samples were heated in the microwave at a certain temperature of 60–75°C for 0.5–1 minute. The results of the 1 minute and 0.5 minute microwave treatment tests can increase wettability so that the spread becomes longer, with a small K value of 0.391. This is presumably because the contact angle is less than 90°. In addition, the treatment also had a small and moderate effect on the color differences that occurred.
