“…All the particleboard, even control samples, failed to meet the maximum allowable thickness swelling of 12% as stipulated in JIS A 5908. The findings were in agreement with Syamani et al [15] who reported that Imperata cylindrica particleboards bonded with 20 wt% citric acid had the lowest TS compared to that of particleboard with 10 wt% and 15 wt%, respectively. As the ester linkages increased along with increasing citric acid content, the adhesiveness improved and subsequently led to improved TS [15].…”

This study investigated the effects of different citric acid content on the physico-mechanical and biological durability of rubberwood particleboard. Particleboards with density of 700 kg/m3 were produced with three different citric acid contents, namely 10, 15 and 20 wt%. Particleboards made from 10 wt% urea formaldehyde (UF) resin were served as control for comparison purposes. FTIR analysis was carried out and the formation of ester linkages between -OH on cellulose and carbonyl groups of citric acid was confirmed. The peak intensity increased along with increasing citric content, which indicated that a higher amount of ester linkages were formed at higher citric acid content. Citric acid-bonded particleboard had inferior physical properties (water absorption and thickness swelling) and mechanical properties (internal bonding strength, modulus of rupture and modulus of elasticity) compared to that of the UF-bonded particleboard. However, the performance of particleboard was enhanced with increasing citric acid content. Meanwhile, citric acid-bonded particleboard displayed significantly better fungal and termite resistance than UF-bonded particleboard owing to the acidic nature of citric acid. It can be concluded that citric acid is a suitable green binder for particleboard but some improvement is needed during the particleboard production process.

“…Pre-drying is a process to reduce the moisture of the particles after sprayed with citric acid solution prior to hot pressing. As reported by Kusumah et al [ 14 ] and Syamani et al [ 15 ], sprayed particles dried at 80 °C for 12 h resulted in particleboard with better physical and mechanical properties.…”

“…Particleboard bonded with 20 wt % CA has significantly lower TS compared to that of the particleboard bonded with 10 and 15% CA. [71] Bending strength of the particleboard increased as the CA content increased from 0 to 20 wt % but decreased when 30 wt % were applied. As for IB strength, 30 wt % resulted in the best result.…”

A Review on Citric Acid as Green Modifying Agent and Binder for Wood

et al. 2020

View full text Add to dashboard Cite

Citric acid (CA) can be found naturally in fruits and vegetables, particularly citrus fruit. CA is widely used in many fields but its usage as a green modifying agent and binder for wood is barely addressed. Esterification is one of the most common chemical reactions applied in wood modification. CA contains three carboxyl groups, making it possible to attain at least two esterification reactions that are required for crosslinking when reacting with the hydroxyl groups of the cell wall polymers. In addition, the reaction could form ester linkages to bring adhesivity and good bonding characteristics, and therefore CA could be used as wood binder too. This paper presents a review concerning the usage of CA as a wood modifying agent and binder. For wood modification, the reaction mechanism between wood and CA and the pros and cons of using CA are discussed. CA and its combination with various reactants and their respective optimum parameters are also compiled in this paper. As for the major wood bonding component, the bonding mechanism and types of wood composites bonded with CA are presented. The best working conditions for the CA in the fabrication of wood-based panels are discussed. In addition, the environmental impacts and future outlook of CA-treated wood and bonded composite are also considered.
