This paper gives the results of ghora neem (Melia azedarach) plywood for assessing it as an alternative raw material for plywood industries. Five ply ghora neem plywood of 2400 mm×1200 mm×12 mm size was manufactured using urea formaldehyde adhesive. The important physical and mechanical properties were examined for assessing its quality. The results of physical and mechanical properties of ghora neem plywood were compared with the data obtained with existing market available plywood manufactured with shimul (Bombax ceiba). The density of ghora neem plywood and shimul plywood was 541.00 and 499.80 kg/m 3 respectively. The MOR was 58.33 N/mm 2 for ghora neem plywood while it was 32.52 N/mm 2 for the shimul plywood. The MOE was found for ghora neem plywood 3950.01 N/mm 2 and on the other hand, the shimul plywood showed 3224.15 N/mm 2 . The ghora neem plywood showed better performance for both physical and mechanical properties and it also follows the standard.

“…Statistical analysis has been informed about the significant difference between two types of plywood (Table II). The MOE is higher for high (Kwon and Geimer, 1998;Ajayi, 2002;Zheng et al, 2007). The standard value of MOE is 6890 to 1310 N/mm 2 (ASTM D3043-87) and this standard is followed by the ghora neem plywood.…”

“…Results for MDI (diphenylmethane diisocyanate) exhibited the lowest contact angles, while MUF (melamine urea formaldehyde) and PF (phenol formaldehyde) had 25% higher values for the contact angle for both untreated and NaOH-pre-treated straw Russell and Johnston 1996). The differences between MDI and UF or PTP (polymeric material from triglycerides and polycarbonic acid anhydrides) and UF are even higher when the internal bond strength is measured (Boquillon et al 2004;Dziurka et al 2005;Mo et al 2003;Zheng et al 2007). The wax layer of the external surface of monocotyledons requires adhesives with a more lipophilic or non-polar character such as the adhesives used in WPCs (wood plastic composites) (Maheswari et al 2012), where natural fibres, which generally have a hydrophilic (polar) character, are chemically or physically treated or used in combination with coupling agents to increase their compatibility with a hydrophobic matrix (Han and Choi 2010;John and Anandjiwala 2008;Kabir et al 2011;Keener et al 2004;Khalil and Suraya 2011;Li et al 2007;Lu et al 2000;Maheswari et al 2012;Sinha and Rout 2009).…”

As a supplier to the furniture industry, the particleboard industry is searching for opportunities to reduce costs, weight, and formaldehyde emissions. One such opportunity is to use monocotyledons such as straw and hemp, as well as grasses like reed canary grass. A major problem when using reed canary grass or other monocotyledons in combination with wood is the difference in their surface properties, leading to poor reactivity and wettability with adhesives such as melamine urea formaldehyde. To this end, either the surface of the particles must be modified in some way, or different adhesives must be used. The purpose of this paper is to present adhesives, surfactants, coupling agents, and pre-treatment methods that can be used in combination with monocotyledons to improve compatibility with wood. Some of the methods have been tested on reed canary grass. The results show a wide range of strength values for the joint between wood and untreated or pre-treated reed canary grass glued with different adhesives, with and without a surfactant and a coupling agent. Isocyanate-based adhesives provided relatively strong bonds, and polyvinyl acetate, acryl, and epoxy adhesives were also effective. The most effective method was pre-treatment followed by adhesives in combination with a coupling agent.

Relation of transverse air permeability with physical properties in different compositions of sugarcane bagasse particleboards

et al. 2012

Studies concerning the production of particleboards with sugarcane bagasse as an alternative fibrous material have been carried out as an attempt to provide a sustainable and viable destination for this residue. This work aimed to evaluate the influence of several processing variables related to the microstructure of sugarcane bagasse particleboards (mat type, adhesive type and adhesive content) on their permeability and water sorption properties. Air permeability data was collected by the rotameter method. Superficial air permeability (kg), Darcian constant (k 1 ) and non-Darcian constant (k 2 ) were measured. kg was related to sorption behavior of the particleboards. 1-layer particleboards presented significantly higher kg values than the 3-layer particleboards. In general, adhesive type, position and content did not influence kg of particleboards. However, these processing variables influenced interactions between fluid and material and tortuosity of the porous media. Particleboards produced with urea-formaldehyde with high kg presented higher water absorption and thickness swelling after 24 hours. Such relations were not observed in particleboards produced with melamine-urea-formaldehyde.
