Abstract

Dregs from the sugar palm (Arenga pinnata) starch industry are considered a waste product of the agricultural industry and have not yet been optimally utilized. Therefore, this study aimed to manufacture particleboards from dregs using different amounts of adhesive and particle size ratios. Sugar palm dregs, which had been separated into fibers and powder/fine particles, were used as raw material for making particleboards. The fiber had an average length of 6.84 ± 3.23 cm, while the fine particles were of a size that passed through size 10 mesh and remained in size 60 mesh. Three ratios of fiber to fine particles (100:0, 75:25, and 50:50 wt%) with three different amounts of sucrose-citric acid adhesive (10, 15, and 20 wt%) were used in this study. Increasing the amount of fine particles and the resin content can improve the physical properties and the internal bond strength of boards made from sugar palm dregs. The fine particles possibly filled the gap between the fibers in the particleboard, while the fibers exhibited a high bending strength. As a result, a high-performance particleboard can be attained by combining the composition ratio of fiber/fine particles and resin content. In this study, particleboards made from fiber/fine particles (75:25 wt%) and adhesive content of 15 wt% and 20 wt% had the mechanical properties that met the requirements of Japanese Industrial Standard (JIS) A 5908 type 18. Sugar palm dregs have the potential to be used as raw materials to create value-added particleboards.

糖棕榈(Arenga pinnata)渣制刨花板的选择性能

糖棕榈(Arenga pinnata)淀粉工业的渣被认为是农业工业的废物，尚未得到最佳利用。因此，本研究的目的是利用不同的粘合剂用量和颗粒大小比例的渣滓生产刨花板。以糖棕榈渣为原料，将其分离成纤维和粉末/细颗粒，制成刨花板。纤维的平均长度为6.84±3.23 cm，而细颗粒的大小通过10目并保持在60目。本研究使用了三种纤维与细颗粒的比例(100:0、75:25和50:50 wt%)，以及三种不同量的蔗糖-柠檬酸粘合剂(10、15和20 wt%)。增加糖棕榈渣板的细颗粒量和树脂含量，可以改善糖棕榈渣板的物理性能和内部粘结强度。细颗粒可能填充了刨花板纤维之间的空隙，而纤维表现出较高的抗弯强度。因此，结合纤维/细颗粒的组成比和树脂含量，可以获得高性能刨花板。在本研究中，由纤维/细颗粒(75:25 wt%)和粘合剂含量分别为15 wt%和20 wt%制成的刨花板的力学性能满足日本工业标准(JIS) A 5908 18型的要求。糖棕榈渣有可能被用作制造高附加值刨花板的原料。

期刊介绍： The Journal of the Korean Wood Science and Technology (JKWST) launched in 1973 as an official publication of the Korean Society of Wood Science and Technology has been served as a core of knowledges on wood science and technology. The Journal acts as a medium for the exchange of research in the area of science and technology related to wood, and publishes results on the biology, chemistry, physics and technology of wood and wood-based products. Research results about applied sciences of wood-based materials are also welcome. The Journal is published bimonthly, and printing six issues per year. Supplemental or special issues are published occasionally. The abbreviated and official title of the journal is ''J. Korean Wood Sci. Technol.''. All submitted manuscripts written in Korean or English are peer-reviewed by more than two reviewers. The title, abstract, acknowledgement, references, and captions of figures and tables should be provided in English for all submitted manuscripts.
