“…The intensity increased as the amount of citric acid and pressing temperature increased. A similar trend was found for bamboo particleboard bonded using citric acid at concentrations ranging from 10% to 40% (Widyorini et al 2014). The carbonyl group was present because of the reaction of the hydroxyl groups from the lignocellulosic materials and carboxyl groups from citric acid (Umemura et al 2011).…”

Citric acid is a potential binding agent for composite products that has three carboxyl groups that can be ester linked with the hydroxyl groups found in wood. The addition of sucrose provides hydroxyl groups and increases the amount of ester groups. This research investigated the bonding ability of a new adhesive composed of citric acid-sucrose for teak particleboard. Citric acid and sucrose were dissolved in water under various ratios, and the concentration of the solution was adjusted to 59 to 60 wt%.This adhesive solution was sprayed onto the particles at 10% resin content based on the weight of air-dried particles. Each mixture was then hot pressed at 180 and 200 °C for 10 min. The physical and mechanical properties of the particleboards were tested, and the results showed that increasing the pressing temperature affected the dimensional stability. However, increasing of citric acid in adhesive composition improved the dimensional stability and mechanical properties of the particleboards. The optimum properties of the board were achieved at a pressing temperature of 200 °C and addition of only 10% citric acid. The results also indicated that the peak intensity of C=O group increased with the addition of citric acid and increasing pressing temperature, indicating that ester linkage occurred. However, the addition of sucrose did not greatly affect the peak intensity of C=O group.

“…Recently, Umemura et al (2012) found that citric acid has good adhesivity for wood and elucidated the physical properties of particleboard bonded with citric acid (Umemura et al, 2013(Umemura et al, , 2014. Furthermore, particleboard produced using bamboo and citric acid was also evaluated and was found to have good physical properties (Widyorini et al, 2014). Citric acid (2-hydroxy-1,2,3-propanetricarboxylic acid) is an organic polycarboxylic acid containing three carboxyl groups.…”

Recently, the investigation of wood-based composites produced using agricultural waste and natural adhesives has become very important due to the decreased wood resources and fossil resource reserves. In this study, sweet sorghum bagasse and citric acid were used as the raw material and natural adhesive, respectively, for the experimental manufacture of particleboards. A pre-drying treatment of sprayed particles was performed to observe the

“…Hal ini diduga karena penambahan asam sitrat dan asap cair sebagai pelarut pada partikel kulit kacang tanah dapat merubah warna dari papan partikel yang dihasilkan. Hal yang sama juga ditemukan oleh Widyorini et al (2014) yang meneliti papan partikel dari bambu dengan penambahan asam sitrat dan Umemura et al (2011) yang meneliti produk cetakan kayu akasia dengan penambahan asam sitrat.…”

Binderlessboard is one of the potential eco friendly products that can be developed. Utiliation of natural adhesives for non-wood composite is still very limited. Therefore, this research is focused on effects of citric acid content and pressing time on characteristics of particleboard made from peanut shell including its durability to dry wood termite attacks. Peanut shell particles were used as raw materials. Citric acid dissolved in liquid smoke which functioned as a water substitute solvent under a certain ratio and the concentration of the solution was adjusted to 60%. The use of liquid smoke is expected to increase the durability of the particleboard. Factors used in this research were citric acid content (10-30% based on dry weight particles) and pressing time (10 minutes and 15 minutes). Properties of particleboard were analyed based on Japanese Industrial Standard (JIS) A 5908 for particleboard. The dry wood termite resistance was then analyzed for its weight loss and mortality after 4 weeks. The results showed that the best particleboard was obtained from the treatment of 30% citric acid content with 15 minutes of pressing time where only the modulus of rupture and modulus of elasticity did not met the requirement of JIS A 5908 type 8 with the thickness swelling were 3.276%, water absorption were 44,991%, internal bonding were 4.679 kgf / cm², modulus of rupture were 26.822 kgf / cm², and modulus of elasticity were 8,986,058 kgf / cm². The best value of weight loss and mortality of dry wood termites on particleboard was obtained in a combination of 30% citric acid content with 10 minutes pressing time were 1.083% and 38.67% respectively.
