Performance of Zephyr Board Made From Various Rolling Crush Number and Palm Oil Petiole Parts

Abstract

The objective of this research was to evaluate physical and mechanical properties of zephyr board made from palm oil petiole parts. The palm oil petiole parts were distinguished on the basis of rolling crushed number (4, 5 and 6 times,as factor A) and base, middle and upper parts of petiole (factor B). The board was made from three layers of petiole with density of 0.75g.cm⁻ 3 and thickness 1 cm respectively using Phenol formaldehyde (PF) with 12% resin as binding agent and compressed the board at 120ºC temperature and 25 kg/cm-2 pressure for 10 minutes. The results showed that physical properties of a zephyr board included of density, moisture content (MC), water absorption (WA), and thickness swelling (TS) were 0.74 g.cm-3 , 12.32%, 29.14%, 5.19%, respectively. Mechanical properties such as modulus of elasticity (MOE), modulus of rupture (MOR), screw with drawl (SW) were 44.7 x 10³ kgf.cm-2 , 268 kgf.cm-2 , 107.32 kgf, respectively. In generally, number of rolling crushed was affected to moisture content, water absorption and MOR value whereas petiole part was significantly affected to MOR value only. Some of properties zephyr boards made from oil palmpetiole fulfill JIS A 5908-2003 standard.

Proposal for a new method for sustainable and advanced utilization of oil palm trunk waste

“…MOR of plywood with a veneer of OPT was 30–37 MPa (Mokhtar et al 2011 ). MOR and MOE of zephyr strand board were about 20–39 MPa and 3.0–6.0 GPa, respectively (Wardani et al 2014 ). Lee et al reported that particleboard made with only rubber wood particles has better properties than particleboard made with rubber wood and OPT (Lee et al 2014 ).…”

“…The obtained wood and bamboo zephyr strands are used to make strand boards (Kim et al 1998 ; Nugroho and Ando 2000 ; Kikata et al 1989a , 1989b ). There are also reports of zephyr strand boards made from oil palm using the zephyr treatment (Wardani et al 2014 ). However, there is no report of using Zephyr treatment for separation.…”

Use of palm waste zephyr boards as a solution for floating building deterioration

“…Palm frond waste which is used as biocomposite is very feasible to be developed so that it can be a solution to replace wood material which is now increasingly scarce. The processing results of this palm waste Zephyr board have a fairly good quality based on testing that can meet the standards of JIS A 5908-20003 Type 18 particle board quality [Wardani, 2014]. [Wardani, 2015], also stated that the quality of Zephyr boards made from waste palm fronds can be compared to other composite boards, the quality of Zephyr boards is better than the quality of plywood made of wood.…”
