SIFAT FISIS DAN MEKANIS PAPAN UNTAI BERARAH DARI BAMBU TALI (Gigantochloa apus (J.A. & J.H. Schultes) Kurz)

Abstract

Bamboo is potential as an alternative material to substitute wood. This paper examines the effects of using different resin contents and strand dimensions on the properties of its oriented strand board (bamboo OSB). Tali bamboo (Gigantochloa apus (J.A. & J.H. Schultes) Kurz) was used as raw material in manufacturing the bamboo OSB. Laboratory scale oriented bamboo strand boards were fabricated using each bamboo strand length (7.5, 10, and 15 cm) and glued with liquid phenol formaldehyde adhesive at various resin contents (6, 7 and 8%) of the bamboo strands dry 3 weight. Results show that the average density of fabricated bamboo OSB was 0.75 g/cm. Physical and mechanical properties of bamboo OSB were significantly affected by resin content, except the modulus of elasticity (MOE). Higher resin content gave better physical and mechanical properties of the boards. MOE of bamboo OSB was also significantly affected by the strand length. The longer strand dimension produces boards with higher MOE values. All oriented bamboo strand boards studied meet the Indonesian and Japanese Standard requirements of type 24 particleboard and also meet the British Standard requirements of both Type OSB/2 and Type OSB/3.

Properties of oriented strand boards made from two Indonesian bamboo species at different pressure levels and strand lengths

“…The values of MOR parallel to the surface grain of bamboo-based OSB in this study were higher than those of OSB, as reported in previous studies (Suzuki and Takeda 2000;Sumardi et al 2008;Hidayat et al 2013;Febrianto et al 2015;Sulastiningsih et al 2017;Iswanto et al 2019;Lunguleasa et al 2021;Zhuang et al 2022a). All MOR values of bamboo-based OSB in this study met the JIS A 5908 (2015) requirements for type 24-10 (OSB type) particleboard (24 and 10 MPa).…”

Sifat Fisik Dan Mekanik Papan Oriented Strand Board (Osb) Dari Limbah Finir Kayu Lapis Berdasarkan Waktu Kempa Dan Konsentrasi Fenol Formaldehida

“…Penelitian Suhadi et al, (2018) Lembaran OSB yang telah dibentuk, pada bagian atas lembaran dilapisi kembali dengan aluminium foil dan diberi lapisan plat seng. Pengempaan dilakukan pada suhu 160℃, dengan waktu kempa bervariasi 8 menit, 10 menit dan 12 menit, dan tekanan kempa sebesar 35kg/cm 3 ( Sulastiningsih et al, 2017). Papan OSB yang telah jadi selanjutnya dilakukan pengkondisian pada suhu kamar selama ± 7 hari sebelum dilakukan pengujian.…”

Sifat Papan Partikel Dari Campuran Kayu Jabon Dan Bambu Andong

“…Pengolahan bambu menjadi produk bambu lamina hanya memanfaatkan bambu berdiameter besar, berdinding tebal dan berbatang lurus. Dalam proses pembuatan bilah bambu dihasilkan limbah berupa bilah dengan ukuran yang tidak teratur sehingga tidak bisa digunakan untuk pembuatan bambu lamina (Sulastiningsih, Indrawan, Balfas, Santoso, & Iskandar, 2017). Di samping itu, dari proses penyerutan bilah bambu dihasilkan limbah berupa partikel bambu dengan volume yang cukup besar.…”
