Allylation of cellulose microfibers for hydrosilylation with various hydrosilanes and hydrosiloxanes, and their application in corn-starch-mimosa tannin (CSMT) adhesive to improve particleboard properties

Recently, Cellulose microfibers (CMF) have garnered significant attention due to their renewability, biodegradability, and unique properties such as high aspect ratio, low density, high strength, stiffness, and distinctive optical properties. These characteristics have been highlighted in publications worldwide. However, the structure of CMF is difficult to access with solvents, limiting its dissolution in common organic solvents. The synthesis of CMF–siloxane or CMF–silane hybrid materials from cellulose generally involves several reactions steps, and therefore catalysts. The allylation of CMF is catalyzed by the phase-transfer catalyst tetrabutylammonium bromide (TBAB), which enables the combination of CMF with allyl. This is followed by a hydrosilylation reaction catalyzed by Karstedt's catalyst, based on platinum (0), to combine the hydrophilic allylated CMF with hydride-terminated hydrophobic hydrosilane or hydrosiloxane. Environmentally friendly particleboards were developed using bio-based adhesives composed of corn-starch and Mimosa tannin (CSMT) mixtures. These mixtures included 4, 6, 8, and 10 wt% of CMF, allylated CMF and silylated CMF. The mechanical and physical properties of particleboards, such as modulus of elasticity (MOE), modulus of rupture (MOR), internal bond strength (IB), surface soundness (SS), water absorption (WA) and thickness swelling (TS) were determined.

Physical and Mechanical Properties of Particleboard from Petung Bamboo-waste using Eco-friendly Chitosan-starch Adhesive

The effect of starch addition in chitosan adhesive on the physical and mechanical properties of petung bamboo particleboard from bamboo-sawing waste was investigated in this work. The utilization of bamboo-sawing waste particles as a raw material for particle board manufacturing has been gaining attention due to its waste reduction potential and economic advantages. The results of this study indicated that starch has been proven to enhance the physical and mechanical properties of petung bamboo particleboard. Adding only 4% wt. of chitosan/starch adhesive with a chitosan/starch ratio of 7/3 (w/w) has resulted in an improvement in the physical properties of the particleboard, such as moisture content, thickness swelling, and water absorption. It has also enhanced the mechanical properties of the particle board, including modulus of elasticity (MOE), modulus of rupture (MOR), and internal bonding (IB), in comparison to chitosan adhesive without starch addition. Overall, these findings provide insights for further developing chitosan/starch adhesive, especially to produce natural-based adhesives with good bonding quality.

EVALUATION OF SELECTED MECHANICAL AND PHYSICAL PROPERTIES OF PARTICLEBOARDS CONTAINING WASTE PLASTICS

This article is focused on the research of particleboards (PB) composed of wood particles from spruce logs and recycled crushed plastic granulates. Crushed plastic granulates sized from 1.0 to 4.0 mm were obtained from worn automobiles by recycling, specifically painted and unpainted bumpers. The proportion of plastic granulate in the particleboards represented 10%, 15%, and 20% of the total weight of the composites. In the production of PB, urea-formaldehyde resin and paraffin emulsion were used as a binder and ammonium nitrate was used as a hardener. The aim of the article was to compare the selected properties of PB containing plastic filler with pure PB. Mechanical properties (tensile and bending strength), and physical properties (water absorption and thickness swelling) were evaluated according to EN 319, EN 310 and EN 317. Based on the results, it can be stated that the bending strength and physical properties of PB containing plastic filler were significantly better compared to pure PB. On the contrary, the tensile strength values were lower in most cases.

Preparation and characterization of wood plastic composite produced from waste polystyrene with organic filler

In this study, polystyrene (PS) polymer composites were prepared and characterized by mechanically and physically. It was aimed to produce a cheap, lightweight, and eco-friendly wood plastic composite (WPC). Waste PS was melted in a cap by gasoline, and 200 % wheat flour (PS(W)), wheat starch (PS(S)), and medium-density fiberboard (MDF) sawdust (PS(D)) were added into the melted PS. After the mixture was well mixed in a dough-like form, it was placed into wooden molds and molds were kept in the oven at 140 °C for 30 minutes and then taken out, and kept for 20 minutes at 4 °C. After the cooling process, the composites were removed from the molds and were cut to 18 mm x 15 mm x 40 mm dimensions using a diagonal saw. Mechanical characterizations were carried out by Internal bonding (IB), Screw holding resistance for edge (SRE) and surface (SRS), Pressure (PR). Physically characterizations were carried out by Density (DN), Water absorption (WA), Thickness swelling (TS). Results show that PS(D) has the highest mechanical properties despite its lowest density. PS(W) sample has better mechanical properties than PS(S) sample. It has been determined that the wood composite obtained by the combination of MDF waste dust with melted waste PS is close to the mechanical and physical properties of particleboard. Waste PS can be blended with wood dust and used on wood composite.

Influence of tannin from Indian almond leaves on the curing behavior of Sucrose-Citric acid adhesive

The development of an eco-friendly wood adhesive composed of renewable materials has become a major topic of wood-based panel industry due to their safety for human health and potential use for particleboard production. Formaldehyde-based wood adhesive can emit formaldehyde which poses as a threat to the indoor air quality. Therefore, several researchers used sucrose, citric acid, and tannin as raw materials for the synthesis of eco-friendly adhesives, since these compounds showed a great synergy effect when used as a wood adhesive. A synthesized Citric-Sucrose-Tannin (CST) adhesives was studied in this work. Tannin, extracted from Indian almond leaves, was added into the 40 wt% of dry sucrose and citric acid in order to increase adhesion efficiency. To form the particleboard hot press is needed, each sample is pressed at temperature of 160 °C for three consecutive steps; four MPa for two minutes, two MPa for two minutes, and one MPa for two minutes. It was found that the optimized proportion of sucrose:citric:tannin in adhesive was 75/25/25 as it gave the particleboard the highest Modulus of Elasticity (MOE) and Modulus of Rupture (MOR) values. Compared to non-adhesive particleboard, the MOR and MOE values were improved by two and four times when this formaldehyde-free adhesive was applied. It can be concluded that the eco-friendly wood adhesive composed of citric, sucrose, and tannin extracted from Indian almond leaves significantly enhanced both the mechanical and physical properties of particleboard.

Effect of Adhesive Content on Physical Properties Particleboard Made from Bamboo and Sugar Palm Waste (Arenga Pinnata (Wurmb.) Merr)

Currently, need for wood as a raw material for making boards has increased, which has reduced the availability of forest resources. To overcome this problem, industrial waste or other lignocellulosic materials are used to make particle board with the aim of efficient use of wood. Particle board has advantages, namely the use of raw materials can be either wood or non-wood waste. Therefore, particle board processing can overcome the problem of handling wood waste which has not been optimally carried out. This research aimed to analyze the physical properties of particle board made from bamboo and sugar palm waste. This study used an experimental method with a completely randomized design (CRD) with one factor (adhesive content), namely 10%, 12%, and 14%. The results of this study showed that physical properties of bamboo particle board at adhesive content of 10%, 12%, and 14% ranged from, respectively: water content (10.26%, 9.96%, dan 9.79%); density (0.69 gr/cm3, 0.68 gr/cm3, dan 0.71 gr/cm3); thickness swelling (21.57%, 20.07%, dan 19.23%). While the palm sugar particle board with adhesive content of 10%, 12%, and 14% respectively: water content (11.29%, 10.91%, dan 10.22%); density (0.70 gr/cm3, 0.69 gr/cm3, dan 0.71 gr/cm3); thickness swelling (26.00%, 22.90%, dan 22.85%). From the physical properties of the two types of particle board, the water content and density of particle board fulfilled JIS A-2003 standard, while thickness swelling did not fulfilled JIS A-2003 standard. Based on the value of moisture content and density, the use of bamboo particle board and palm sugar is suitable for interior materials.

The Improvement of Sumatran Elephant (Elephas maximussumatranus) Dung Particleboard Characteristics Using Bamboo Layering.

The use of natural fibers or particles as alternative raw materials for particleboard production is essential due to the shrinking forest area. Currently, dung waste from the Sumatran elephant (Elephas maximus sumatranus) is being used as a raw material for particleboard due to its high fiber content. Although the product still has inferior mechanical and physical characteristics, it can be improved by layering bamboo. Therefore, this study aimed to enhance the mechanical and physical qualities of elephant dung particleboard by adding layers of bamboo. The particleboard constructed had three layers; namely, the face and back in the form of a bamboo layers, as well as the core, which was in the form of elephant dung. The elephant dung was evenly mixed with isocyanate adhesive using a spray gun, and the bamboo layers were coated with adhesive on one side of the surface. The sample was subjected to a hot press at a temperature of 150 °C and 30 kg/cm2 pressure for 10 min. Generally, JIS A 5908-2003 is the specification used to test the physical and mechanical properties of particleboard. During the experiment, the characteristics examined include density, moisture content, water absorption, thickness swelling, modulus of elasticity, modulus of rupture, and internal bonding, which were enhanced by using layers of bamboo. The results showed that the physical properties of the particleboard with bamboo layers were a density of 0.62–0.69 g/cm3, a moisture content of 7.87–10.35%, water absorption of 38.27–68.58%, and a thickness swelling of 10.87–30.00%, which met the minimum standards of JIS A 5908-2003. The mechanical characteristics had values for the modulus of elasticity of 1952–7282 MPa, the modulus of rupture of 20.44–68.27 MPa, and the internal bonding of 0.16–0.38 MPa, which met the JIS A 5908-2003 standard. Based on these results, the particleboard with Belangke bamboo layers was the best in this study.

Effects of Planting Density of Rubber Tree Clone (RRIM 2020 Clone and RRIM 2025 Clone) Wood to Particleboard Properties

The depletion of log resources encourages research into alternative ways to sustain the wood supply. Therefore, the 4-year-old Rubber Research Institute of Malaysia (RRIM) clones series, RRIM 2020 and RRIM 2025, were chosen as potential raw materials for particleboard in this study. The purpose of this study was to assess the effects of planting density and rubber tree clones on the mechanical and physical properties of single-layer particleboard. The planting densities used were low, moderate-low, moderate-high, and high, representing 500, 1000, 1500, and 2000 trees/ha, respectively. Prior to manufacturing, the RRIM 2000 series clone trees were harvested, cut, chipped, flaked, and screened. The mechanical and physical properties were evaluated in accordance with the Japanese Industrial Standard (JIS A 5908-2003). The findings revealed that both planting density and clone had a signifi- cant impact on the mechanical and physical properties of particleboard with a thickness of 10 mm and a density of 700 kg/m3 . RRIM 2020 specimens with low planting density had superior modulus of elasticity (MOE), modulus of rupture (MOR), and internal bonding (IB) values of 2415, 19, and 1.7 MPa, respectively. Furthermore, moderate-low planting density demonstrated the lowest thickness swelling (TS) and water absorption (WA) values and was comparable to control particleboard from commercial clone Prang Besar (PB), PB260. In terms of rubber clones, RRIM 2020 particleboard met the minimum requirements of the JIS standard for mechanical properties and outperformed RRIM 2025. This study recommended a low planting density of 500 trees/ha and the RRIM 2020 clone as a suitable raw material for particleboard manufacturing with a ten percent urea formaldehyde resin content.

Effect of the addition of lignin on the physical-mechanical properties of particleboards made with pine/hydrangea stems

ABSTRACT The effect of adding different lignins on the physical and mechanical properties of particleboards made with stems of hydrangea and pine using the urea–formaldehyde (UF) resin was evaluated. Four types of lignin were characterized by Fourier-transform infrared spectroscopy and Klason lignin: Cane Bagasse lignin, Pine China lignin, Kraft Brazil lignin, and ammonium lignosulfonate (LSA). Particleboards were prepared with four types of lignin in a 1:1 (w/w) UF/lignin ratio and compared with those prepared with the UF resin without lignin (control sample). Water absorption, thickness swelling, rupture modulus, and modulus of elasticity were measured. The type of lignin used does not have a statistically significant difference in the physical and mechanical properties and also a decrease in the physical properties of the particleboards compared with the control sample. The use of LSA in the 3:1 (w/w) UF/lignin ratio allows to elaborate particleboards with mechanical properties like those found in the control sample.

The influence of particleboard resination on their internal bond strength

The influence of particleboard resination on their internal bond strength. The aim of the project was to investigate the main mechanical and physical properties of particleboards, especially focused on internal bond, in terms of their resination. For the tests, the particleboards have been produced in laboratory conditions with the following glue content: 7, 10, 15, 30 and 50%. Particular attention was paid for examining the mechanical property – tensile strength perpendicular to surfaces (Internal Bond – IB). In addition, there were investigated modulus of elasticity (MOE), modulus of rupture (MOR) density and density profile. In the light of above mentioned tests, there is no positive effect of improvement of tested parameters when raise resination over 30% when producing particleboards. With the resination increase from 7 to 50% a significant change (densification) of panels’ structure, as well as differences between face and core layers density have been found.

Investigation of the use of old railroad ties (Fagus orientalis) and citrus branches (orange tree) in the particleboard industry

Effects of two widely available and underutilized lignocellulosic materials on the mechanical and physical properties of particleboards were investigated in this work. The ratio of mixtures lignocellulosic flakes at four levels (100% aspen wood), (50% aspen wood: 25% citrus: 25% old railroad ties), (50% aspen wood: 50% citrus), and (50% aspen wood: 50% old railroad ties), and the percentage of resin in two levels (8 and 12%) were considered as variable factors. The 100% aspen wood (Populus tremula) was mixed as a control board (100% aspen wood). Then the mechanical and physical properties of the samples including modulus of rupture, modulus of elasticity, internal bond, water absorption, and thickness swelling after 2 h and 24 h of immersion (EN 310-319) and fire resistance (ISO 11925-2) were measured. The results showed that with increasing poplar wood in mixtures, modulus of rupture, modulus of elasticity, internal bond increased, while water absorption and thickness swelling decreased. Also, in comparison with the control boards, the boards that were made by mixing 50% poplar and 50% citrus branches with 12% glue had the highest mechanical strength. The results also showed that increasing the amount of old railroad ties chips in mixing caused a significant decrease in the fire retardancy of the boards.

Modification of rice biomass wastes for eco-friendly particleboard

Rice husk and rice straw are some of abundantly available agricultural wastes that could substitute the utilization of wood as particleboard raw-materials. Nevertheless, recent studies show that rice husk and rice straw instigated low mechanical and physical properties of particleboard. Modification of rice husk and rice straw particle was investigated in order to improve particleboard properties by immersing rice husk and straw in boiling water (100°C) for 0.5, 1, 2 h and in Na2CO3 (80°C) for 1 h, and combination of rice husk as face and back layers and rice straw as core layer. The boards were manufactured under pressing conditions of 200°C for 10 min used citric acid and sucrose as adhesive. Pre-treatment of 1 h boiling water of particle resulted the highest quality of all properties and satisfy the JIS 5908 (2003) requirement in Modulus of Rupture (MOR) and Internal Bonding (IB). Combining rice husk as face and back layer and rice straw as core layer resulting in IB improvement. Compared to the other adhesives, citric acid and sucrose adhesives showed better mechanical and physical properties for rice husk and rice straw particleboard manufacturing.

Physical and chemical properties of particleboard made of rice straw and plastic waste

Rice straw is agricultural waste which hasn’t been used optimally yet, especially in Indonesia. Meanwhile, rice straw contains cellulose that can be used form composite such particleboard. In this study, the physical and chemical properties of particleboard made of rice straw particle and polypropylene from plastic waste as adhesive were investigated. The rice straw and polypropylene compositions were varied: 30:70, 40:60, 50:50, and 60:40 wt.%. The rice straw particle sizes were varied for 40 mesh, 50 mesh, and 60 mesh for each composition. X-Ray Fluorescent has been used to measure the chemical composition of our particleboard. The density of particleboard is 0.59-0.77 g / cm3. Its thickness swelling is less than 2%. Both density and thickness swelling has met the requirement for Indonesian Standard of particleboard. Our results showed that the density of particleboard strongly depends on rice straw particle size. As the particle size decreases, the density increases. The particle size of rice straw affects the thickness swelling of particleboard. The thickness swelling decreases as the particle size decreases. The major constituents of our particleboard are the SiO2, CaO, K2O. Our finding showed that the particle size has an essential role in the physical properties of particleboard.

Mechanical and Physical Properties of Particleboard from Untreated and Treated Kenaf Particles

Composite panels were manufactured from kenaf particles and treated with two different alkali treatments using 2% NaOH and 2% KOH with resin contents of 8% and 10% of phenol formaldehyde (PF) at medium density of 650kg/m3. The objectives of this study were to determine the mechanical properties in terms of its modulus of rupture (MOR), modulus of elasticity (MOE) and internal bond (IB), and physical properties namely thickness swelling (TS) and water absorption (WA) of treated kenaf board. The mechanical and physical tests were performed according to the Malaysian Standard (MS1787:2004). The minimum requirements value for MOE, MOR and IB were 2000 MPa, 14 MPa and 0.45 MPa respectively for furniture grade particleboards for use in humid conditions (PF2). According to Malaysian specifications for physical properties, the maximum requirement for thickness swell is 15%. Results indicated that both treated boards with NaOH and KOH showed an increase in strength properties compared to untreated particleboard. Particleboard treated with KOH exhibited the highest MOR and MOE values, while board with NaOH treatment gave the highest IB value. The boards with treated particles gave better performance in terms of physical properties. There were no significant differences in mechanical properties (MOR, MOE and IB) and physical properties for the different alkali treatment. The values of bending strength and IB strength increased with an increase in resin content, while TS and WA increased with a decrease in resin content. In conclusion, NaOH and KOH treated kenaf particles improved board performance and could be considered as an alternative material for particleboard production.

 highlights:
 Particleboards were successfully manufactured with using of the MIP waste as
 adhesive. Although the MIPW (25%) boards were provided lower mechanical and
 physical values than neat MIP resin (13%) boards, they were satisfied the most
 of standard requirements.

Preparation of Particleboard Using Dialdehyde Starch and Corn Stalk

Particleboard was manufactured using dialdehyde starch (DAS) as the adhesive and corn stalk as the matrix. The adhesive was prepared via the oxidation of tapioca starch in sodium periodate. The DAS was characterized by Fourier transform infrared (FTIR) spectroscopy. The effect of the hot pressing temperature, board density, and DAS dosage on the physical properties of particleboard was studied. The cross-section morphology of particleboard was observed via scanning electron microscopy (SEM). The absorption peak of the aldehyde group appeared at 1731 cm-1 after the tapioca starch was oxidized by sodium periodate, indicating that DAS had formed. Both the modulus of rupture (MOR) and modulus of elasticity (MOE) increased first and then decreased, with the increase of hot pressing temperature, board density, and DAS dosage. Within a certain range, the increase of hot pressing temperature, board density, and DAS dosage reduced the thickness swelling (TS) and improved the particleboard water resistance. During the particleboard hot pressing process, DAS filled the spaces of the corn stalk and acted as an adhesive to bind the corn stalks tightly together, thereby improving the physical, mechanical, and water resistance properties of the particleboard.
