“…A series of studies have shown that the strand from a single bamboo species is a suitable raw material for BOSB production. In previous studies by the authors, Andong (Gigantochloa pseudoarundinacea) and Betung (Dendrocalamus asper) bamboos were exceptionally promising raw materials for the production of BOSBs (Febrianto et al 2012;Adrin et al 2013;Febrianto et al 2015;Maulana et al 2017;Fatrawana et al 2019;Maulana et al 2019a,b). The BOSBs manufactured from Betung bamboo with steam treatment followed by rinsing with a 1% NaOH solution had reasonable properties in terms of commercial utilization (Fatrawana et al 2019;Maulana et al 2021a).…”

“…In addition, steam treatment increases the durability of the BOSBs to weathering as well as its resistance against Coptotermes curvignathus and Cryptotermes cynocephalus termites (Febrianto et al 2013;Maulana et al 2019a). Furthermore, steam treatment followed by rinsing with a 1% NaOH solution improves the quality of the BOSB and meeting commercial OSB standards (Fatrawana et al 2019).…”

Physical and mechanical properties were evaluated for bamboo-oriented strand boards (BOSB) prepared with combinations of two contrasting bamboo species and bonded with phenol formaldehyde resin under various compression ratios. The strands from the culms of Gigantochloa pseudoarundinacea and Dendrocalamus asper bamboo were steam-treated at a temperature of 126 °C and a pressure of 0.14 MPa for 1 h and then washed with a 1% NaOH solution. Three-layer dual-species bamboo-oriented strand boards with a shelling ratio of 25 to 50 to 25 (face to core to back) were manufactured with different compression ratios using an 8% phenol formaldehyde adhesive and 1% paraffin. The slenderness ratio and aspect ratio were evaluated by measuring 100 random strands to determine uniformity. The solidity profiles of the dual-species bamboo-oriented strand boards (thickness direction) were relatively uniform. The modulus of rupture, modulus of elasticity, and internal bond values of the dual-species bamboo-oriented strand boards increased as the compression ratio increased, but the water absorption and thickness swelling decreased. The dual-species bamboo-oriented strand boards prepared with compression ratios of 1.44 to 1.25 and 1.54 to 1.33 met all the requirements of CSA standard 0437 (2011). The optimum compression ratio for the preparation of dual-species bamboo-oriented strand boards was 1.44 to 1.25.

“…2). When impregnated with hot water, extractives (starch, lowmolecular sugar, tannin and gum) are dissolved, and a hydrolysis reaction happens about hemicellulose (Fatrawana et al 2019). The acetyl groups on the hemicellulose molecular chain are dissolved in water to generate organic acid (mainly acetic acid).…”

Poplar and pine wood were extracted with water, 1% NaOH (wt%) solution, and benzene:ethanol solution (V1 : V2, 2 : 1) to investigate the governing factors and mechanism by which extractives affect wood structure and mechanical properties. The structure, pore distribution, crystal structure, and mechanical properties of samples were analyzed by Fourier transform infrared spectroscopy (FTIR), adsorption of N2 gas, X-ray diffraction (XRD), and mechanical testing, respectively. The results demonstrated that cellulose, hemicellulose, and lignin were degraded to some extent in the course of the dissolution of the extractives. This degradation had a great influence on the structure and quantity of pores. The extraction treatment did not change the crystallization type of the wood, but it increased the crystallinity of the wood, and the length and width of the crystallization area changed. In addition, the mechanical properties of wood were changed when the content of the extractives was reduced.

“…Previous studies reported that strands steam treatment at the temperature of 126°C under a pressure of 0.14 MPa for 1 h could improve dimensional stability and some mechanical properties of the OSB (Febrianto et al 2015;). In addition, steam treatment could reduce the extractive substances and starch in strands (Fatrawana et al 2019).…”

The objective of this study was to evaluate the effects of steam treatment of strands on the physical and mechanical properties of oriented strand board (OSB) from gmelina wood (Gmelina arborea) bonded with two types of adhesive. Strands of gmelina wood were steamed at 126°C and pressure of 0.14 MPa for 1 h. OSBs were prepared with a 0.6 g/cm3 target density using two types of adhesives, namely methylene diphenyl diisocyanate (MDI) and phenol-formaldehyde (PF) resins. The resin content used was 5% for MDI and 10% for PF. The physical and mechanical properties of the OSB were evaluated referring to the JIS A 5908-2003 standard, and the values were compared with CSA 0437.0 (Grade O-1) standard. The results showed that the steam treatment improved the dimensional stability of OSB, as shown from the decrease of water absorption and thickness swelling. Steam treatment also increased the mechanical properties of the OSB, such as modulus of elasticity, modulus of rupture, internal bonding strength, and screw holding power. The results revealed that gmelina wood OSB bonded with MDI adhesives produced better OSB than bonded with PF resin.
