The influence of raw material growth region, anatomical structure and chemical composition of wood on the quality properties of particleboards

Abstract

In the present study, the impact of raw material grown region on the physical, mechanical, surface properties and formaldehyde emission of the particleboard was investigated. Ailanthus altissima wood grown in Trabzon had longer fiber length and thicker fiber and trachea cell wall than those of the wood grown in Artvin. The highest amounts of lignin, ash, condensed tannin and solubility values were found in wood grown in Artvin. Ailanthus altissima wood grown in Trabzon had higher amounts of cellulose and hemicellulose than those of the wood grown in Artvin. Particleboards made from wood grown in Artvin had worse surface quality and mechanical strength properties than those of panels made from wood grown in Trabzon. On the other hand, the results showed that particleboards produced from wood grown in Artvin had lower thickness swelling and formaldehyde emision values than those of the panels produced from wood grown in Trabzon.

Chemical composition of Luffa aegyptiaca Mill., Agave durangensis Gentry and Pennisetum sp.

“…The pH of A. durangensis bagasse, plant and leaves of Pennisetum sp. is similar to Ailanthus altissima (5.9) (Bardak, Nemli & Tyriaki, 2017) and Populus canadensis moench (5.97) (Baharoglu et al, 2013). L. aegyptiaca fruit presented a pH close to Pinus brutia Ten.…”

Low-formaldehyde emission composite particleboard manufactured from waste chestnut bur

“…Holocellulose is the main component of wood cell wall. The strength of wood is due to the cellulose and in part to the hemicelluloses, and lower holocellulose content might directly affect the cell structure of wood, thereby reducing the mechanical properties of wood [21]. Lignin plays a role in connecting cells and imparting rigidity of the cell.…”

Karakteristik Papan Partikel Campuran Limbah Sengon Dan Bagas Sorgum Menggunakan Perekat Asam Sitrat

“…Sengon mengandung selulosa 57,11% (Putra et al, 2018), sedangkan bagas sorgum mengandung selulosa 34,87% (Kusumah et al, 2016). Kandungan selulosa yang tinggi ini memudahkan masuknya air ke dalam papan partikel (Sari, Ayrilmis, Nemli, Baharoğlu, Gümüşkaya, & Bardak, 2012;Bardak, Nemli, & Tiryaki, 2017). Selain itu, penurunan DSA papan partikel disebabkan oleh partikel bagas sorgum lebih kecil dibandingkan partikel sengon.…”

“…Keberadaan zat ekstraktif berpengaruh terhadap ikatan perekat CA. Hal ini sesuai dengan yang dinyatakan Sari et al (2012) dan Bardak et al (2017) bahwa zat ekstraktif berpengaruh terhadap kemudahan perekat dalam berpenetrasi terhadap bahan, sehingga menghalangi perekat untuk berikatan dengan bahan dan menghasilkan IB yang tidak maksimal. Selain itu, Widyorini, Umemura, Soraya, Dewi, dan Nugroho, (2019) mengungkapkan bahwa penghilangan zat ekstraktif pada bahan berlignoselulosa mampu meningkatkan kualitas papan partikel.…”
