Abstract

Soy protein is known for its eco-friendly, sustainable, and biodegradable qualities that are likely used as raw material in producing bioadhesive. However, soy protein-based adhesive are lacking in terms of adhesive strength and water-resistance compared to commercial formaldehyde-based adhesives such as phenol and urea-formaldehyde resin. Therefore, continuous research has been done to improve adhesive performance. This can be done via physical or modification methods, including the usage of cross-linking agents, structural modification, enzymatic modification, and the addition of additives. This review will cover these modification methods that give significant enhancement to the water-resistance and adhesive strength of soy protein-based adhesives. KEYWORDS adhesive performance, adhesive strength, modification, soy protein-based adhesive, water-resistance, 1 | INTRODUCTION Adhesives have been used in many different products such as, shoes, plasters, packaging, self-adhesive notes/ envelopes, as well as in wood composites. Formaldehyde-based adhesives such as urea-formaldehyde [...]

Abstract

Oil palm biomass is an abundant source of material. Mass production of palm oil results in increasing amount of waste where roughly 4 kg of dry biomass is produced for each palm oil obtained, with a third is found in fresh fruit bunch (FFB) derived wastes. In contrast, the other two-thirds are represented by trunk and frond material. This problem might be a contribution to the increment of wastes production. One of the alternatives ways is to utilise the oil palm biomass by producing particleboard from oil palm trunk particles. This study was conducted to focus on the effect of pressing time on the properties of particleboard made using glutaraldehyde treated oil palm particle. The different pressing time used in this experiment was 10, 15 and 20 minutes. The made particleboards were tested for their physical and mechanical properties. Results found that the particleboard of 15 minutes pressing time particleboard has the highest value with 390.48 N/mm² and 2.61 N/mm² of MOE and MOR, respectively. Therefore, the 15 minutes pressing time is considered optimum to produce the particleboard with higher strength. [ABSTRACT FROM AUTHOR]
