Abstract

The effect of shredded waste office paper was considered when producing one-layered particleboard. Five different mixing ratios of shredded waste office paper/wood particles were used (0/100, 25/75, 50/50, 75/25, and 100/0) and two amounts of urea formaldehyde (UF) resin (10% and 15%). The boards were tested for their physical and mechanical properties, including modulus of elasticity (MOE), bending strength (MOR), and internal bond (IB) strength, in accordance with the European Norm (EN) standards. All properties of the boards were found to be improved via increasing the resin content. The 15% UF-bonded board with 100% wood particles had the highest MOR, whereas the board containing 100% wastepaper for 15% UF had the highest MOE. However, there was no statistical difference between the board types. Although increasing wastepaper content in the board negatively affected the IB, the usage of wastepaper up to 25% was shown to be acceptable as a raw material in the production of particleboard. None of the prepared boards met the EN 312 (1999) requirements for thickness swelling. The boards made from shredded waste office paper were more suitable for dry and indoor use.

在刨花板生产中将办公废纸碎粒作为木粒的组成部分

在生产单层刨花板时考虑了办公废纸碎料的影响。使用了五种不同的办公碎纸/木材颗粒混合比例（0/100、25/75、50/50、75/25 和 100/0）和两种脲醛（UF）树脂用量（10% 和 15%）。根据欧洲规范 (EN) 标准，对木板的物理和机械性能进行了测试，包括弹性模量 (MOE)、弯曲强度 (MOR) 和内部粘结强度 (IB)。通过提高树脂含量，木板的所有性能都得到了改善。含有 100% 木质颗粒的 15% UF 粘合木板的 MOR 最高，而含有 100% 废纸的 15% UF 粘合木板的 MOE 最高。不过，不同类型的板材之间没有统计学差异。虽然增加板材中的废纸含量会对 IB 产生负面影响，但在生产刨花板时，废纸的使用量不超过 25% 也是可以接受的。所有制备的板材都不符合 EN 312（1999）对厚度膨胀的要求。用办公室废纸碎料制成的板材更适合干燥和室内使用。

期刊介绍： The purpose of BioResources is to promote scientific discourse and to foster scientific developments related to sustainable manufacture involving lignocellulosic or woody biomass resources, including wood and agricultural residues. BioResources will focus on advances in science and technology. Emphasis will be placed on bioproducts, bioenergy, papermaking technology, wood products, new manufacturing materials, composite structures, and chemicals derived from lignocellulosic biomass.
