The potential of producing eco-friendly, formaldehyde-free, high-density fiberboard (HDF) panels from hardwood fibers bonded with urea-formaldehyde (UF) resin and a novel ammonium lignosulfonate (ALS) is investigated in this paper. HDF panels were fabricated in the laboratory by applying a very low UF gluing factor (3%) and ALS content varying from 6% to 10% (based on the dry fibers). The physical and mechanical properties of the fiberboards, such as water absorption (WA), thickness swelling (TS), modulus of elasticity (MOE), bending strength (MOR), internal bond strength (IB), as well as formaldehyde content, were determined in accordance with the corresponding European standards. Overall, the HDF panels exhibited very satisfactory physical and mechanical properties, fully complying with the standard requirements of HDF for use in load-bearing applications in humid conditions. Markedly, the formaldehyde content of the laboratory fabricated panels was extremely low, ranging between 0.7–1.0 mg/100 g, which is, in fact, equivalent to the formaldehyde release of natural wood.

The purpose of this study was to evaluate the feasibility of using magnesium and sodium lignosulfonates (LS) in the production of particleboards, used pure and in mixtures with urea-formaldehyde (UF) resin. Polymeric 4,4′-diphenylmethane diisocyanate (pMDI) was used as a crosslinker. In order to evaluate the effect of gradual replacement of UF by magnesium lignosulfonate (MgLS) or sodium lignosulfonate (NaLS) on the physical and mechanical properties, boards were manufactured in the laboratory with LS content varying from 0% to 100%. The effect of LS on the pH of lignosulfonate-urea-formaldehyde (LS-UF) adhesive compositions was also investigated. It was found that LS can be effectively used to adjust the pH of uncured and cured LS-UF formulations. Particleboards bonded with LS-UF adhesive formulations, comprising up to 30% LS, exhibited similar properties when compared to boards bonded with UF adhesive. The replacement of UF by both LS types substantially deteriorated the water absorption and thickness swelling of boards. In general, NaLS-UF-bonded boards had a lower formaldehyde content (FC) than MgLS-UF and UF-bonded boards as control. It was observed that in the process of manufacturing boards using LS adhesives, increasing the proportion of pMDI in the adhesive composition can significantly improve the mechanical properties of the boards. Overall, the boards fabricated using pure UF adhesives exhibited much better mechanical properties than boards bonded with LS adhesives. Markedly, the boards based on LS adhesives were characterised by a much lower FC than the UF-bonded boards. In the LS-bonded boards, the FC is lower by 91.1% and 56.9%, respectively, compared to the UF-bonded boards. The boards bonded with LS and pMDI had a close-to-zero FC and reached the super E0 emission class (≤1.5 mg/100 g) that allows for defining the laboratory-manufactured particleboards as eco-friendly composites.

This study investigated certain aspects of physical and mechanical properties and resistance against biological deterioration of particleboard panels treated with extractives from different parts of Cerbera odollam trees. Particles of rubber-wood ( Hevea brasiliensis) treated with extracts of leaf, fruit, wood, bark, flower, and seed of Cerbera odollam were used to manufacture panels in laboratory conditions. Two types of adhesive, namely melamine urea formaldehyde and phenol resorcinol formaldehyde were used as binder for the panels. Treated panels had higher resistance against powder post beetle in laboratory as well as field exposures. Both thickness swelling and internal bond strength values of treated samples satisfied requirements for P4 Type particleboards stated in European Standards (EN 312). It appears that such extractives possess potential to enhance resistance of particleboard against insect damage in tropical countries.

The development of natural adhesives derived from non-fossil resources is very important for the future. This research aimed to develop natural adhesive from maltodextrin and compare it with other natural adhesives such as citric acid and malic acid for particleboard production. The effect of the adhesive raw materials on the physical and mechanical properties of the particleboards was investigated. The sweet sorghum and those natural adhesives were used in the manufacturing of particleboard. The resin content of the natural adhesive was 20 wt% base on air-dried particles. The dimension and density target of the boards were 30 x 30 x 0,9 cm3 and 0,8 g/cm3, respectively. The particleboards were prepared by hot pressing at 200°C for 10 min. The physical and mechanical properties of particleboards were evaluated based on Japanese Industrial Standard for particleboard (JIS A 5908-2003). The results showed that the density, moisture content, modulus of elasticity, and modulus of rupture met the requirements of the JIS A 5908-2003 standard, while the thickness swelling, water absorption, and internal bond did not meet the standard requirements. The results of FTIR analysis indicated the establishment of ester linkages due to the reaction between the natural adhesive and sorghum bagasse that contributed to the excellent physical and mechanical properties of the particleboard.Keywords: cassava, maltodextrin, natural adhesive, particleboard, sweet sorghum

The study aimed to analyze the quality of particle boards from bark fiber of sago (Metroxylon spp) with citric acid as natural adhesives based on physical properties, mechanical properties, and durability from subterranean termites Coptotermes curvignathus Holmgren. Particle boards are made with a size of 30 cm x 30 cm x 1 cm. The experimental factors used in the study included densities (0.7 gr/cm3 and 0.8 gr/cm3) and concentrations of citric acid adhesives (20% and 30%). The material then flow into hotpress with 1800C for 15 minutes and pressure at 25 kg/cm2. Testing of the physical and mechanical properties of particle boards refers to the JIS A 5908-2003 standard and durability against subterranean termites Coptotermes curvignathus Holmgren was conducted based on SNI 01. 7207-2006. The results showed that the densities factor had a significant effect on density, thickness swelling, MOE, MOR, internal bond, screw holding strength, and weight loss of the particle board against termites. Meanwhile concentration of citric acid adhesive significantly affected the density, moisture content, water absorption, thickness swelling, MOR, internal bond, and screw holding strength. The interaction between the densities factor and concentration of citric acid has a significant effect on thickness swelling and density. The physical and mechanical properties of particle boards which fulfill the JIS A 5908 2003 standard were density, moisture content, MOR, and screw holding strength. The durability of particleboard againts termites has a very strong level. The average values of termites mortality were 94% ~ 100%. The average of wood weight loss values were 9.61%~ 18.51%. The particle board made with a density 0.8 gr/cm3 and concentration of citric acid adhesive 30% achieved the highest values on physical properties, mechanical properties and durability to the termites Coptotermes curvignathus.

Particleboard was produced by mixing oil heat-treated rubberwood particles at different ratios, with the goal of achieving high dimensional stability. Rubberwood particles were soaked in palm oil for 2 h and heat treated at 200 °C for 2 h. The treated particles were soaked in boiling water for 30 min to remove oil and were tested for chemical alteration and thermal characterization via Fourier-transform infrared spectroscopy and thermogravimetric analysis. Particleboard was fabricated by mixing treated rubberwood particles (30%, 50%, and 70%) with untreated particles (70%, 50%, and 30%, respective to previous percentages) and bonded with urea-formaldehyde (UF) resin. The results revealed that oil-heat treated particles had greater thermal stability than the untreated particles. The addition of oil heat treated particles improved the physical properties of the particleboard with no significant reduction in mechanical strength. However, this was only valid for ratios of 70% untreated to 30% treated and 50% untreated to 50% treated. When a ratio of 70% oil heat treated particles was used, both the physical and mechanical properties were reduced drastically, due to bonding interference caused by excessive oil content. Particleboard made with a ratio of 5:5 (treated to untreated) exhibited the best physical and mechanical properties.
