摘要

这项研究工作的重点是开发一种替代方法,通过压缩成型制造基于木皮(WVs)和高密度聚乙烯(HDPE)的木塑复合板(WPC),从而提高其物理性能,特别是吸水性和含水率。本研究的目的是开发替代板材,以取代受炎热潮湿气候严重影响的商用板材。在这种情况下,研究从设计过程开始,包括收集和加工原始材料、生产制造过程所需的其他组件、确定 WV 比率和制备样品。之后,对木塑、高密度聚乙烯(对照)、商用石膏板(GB)、胶合板(PW)和中密度纤维板(MDF)样品进行了物理和机械测试。结果表明,制造木塑样本的方法改善了物理特性,在测试的两种置换比例中,吸水率均低于 4%,而商用板的吸水率则在 10% 到 40% 之间。此外,对于厚度较低的部件,还实现了更大的承载能力。

Sustainable WPC Production: A Novel Method Using Recycled High-Density Polyethylene and Wood Veneer
This research work is focused on the development of an alternative method for manufacturing Wood Plastic Composite (WPC) panels based on Wood Veneers (WVs) and High-Density Polyethylene (HDPE) through compression molding, which enhances the physical properties, particularly, water absorption and moisture content. The aim of the present research was to develop alternative panels to replace commercial ones, which are heavily affected by hot, humid climates. In this context, the study began with the design process, which consisted of the collection and processing of primary material, production of the additional components necessary for the manufacturing process, determination of the WV ratio, and preparation of the samples. Thereafter, physical and mechanical tests were carried out on WPC, HDPE (control), commercial gypsum boards (GBs), plywood (PW), and medium density fiberboard (MDF) samples. The results indicate that the method applied to manufacture the WPC samples improved physical properties, achieving a water uptake of less than 4% in both proportions of replacement tested, in contrast to commercial panels, which reached values between 10% and 40%. In addition, a greater load capacity was achieved for lower thick elements.
