This work presents a study on the use of wood and plastic wastes generated in abundance in Merida, Mexico, to help to reduce them in order to mitigate environmental deterioration. The use of these wastes is proposed to obtain a low-cost building material. So, the escalation process (i.e., extrusion) at the pilot level to obtain a prototype of a wood–plastic composite (WPC) corrugated sheet to evaluate the technical feasibility to make a low-cost product is reported. A corrugated sheet with recycled high-density polyethylene (R-HDPE) was produced. The R-HDPE was collected from Merida’s Separation Plant. The wood came from the trimmings of different varieties of trees and shrubs that are periodically pruned. WPC sheets with virgin HDPE were prepared to assess its effect on the materials’ mechanical performance. The wood/HDPE weight ratio was 40/60. The performance of the WPC sheets was compared with that of commercial products with similar characteristics, namely acrylic and polyester sheets reinforced with fibreglass, and black asphalt-saturated cardboard sheets. Thus, the effect of natural weathering on the maximum tensile tearing force and on the maximum flexural load of the different types of sheets was evaluated. Although the mechanical performance of the WPC sheets was lower than that of the acrylic and polyacrylic sheets, their performance was much better than that of the cheap black asphalt-saturated cardboard sheets. So, they are a good option to be used as low-cost temporary roofing.

树木修剪和回收塑料产生的潜在废物用于获取建筑材料:墨西哥梅里达的案例研究。

这项工作对墨西哥梅里达大量产生的木材和塑料废物的使用进行了研究,以帮助减少它们,以减轻环境恶化。提议使用这些废物以获得低成本的建筑材料。因此,据报道,在试点阶段进行了逐步升级(即挤压)工艺,以获得木塑复合材料(WPC)瓦楞纸板的原型,以评估制造低成本产品的技术可行性。制备了具有再循环的高密度聚乙烯(R-HDPE)的瓦楞纸。R-HDPE是从梅里达分离厂收集的。木材来自定期修剪的各种树木和灌木的装饰物。准备了具有原始HDPE的WPC板材,以评估其对材料机械性能的影响。木材/ HDPE的重量比为40/60。将WPC板的性能与具有类似特性的商业产品(即用玻璃纤维增​​强的丙烯酸和聚酯板,以及黑色沥青饱和纸板板)的性能进行了比较。因此,评估了自然风化对不同类型片材的最大拉伸撕裂力和最大挠曲载荷的影响。尽管WPC板的机械性能低于丙烯酸和聚丙烯酸板的机械性能,但其性能却比便宜的黑色沥青饱和纸板板的机械性能好得多。因此,它们是用作低成本临时屋顶的好选择。和黑色沥青饱和纸板。因此,评估了自然风化对不同类型片材的最大拉伸撕裂力和最大挠曲载荷的影响。尽管WPC板的机械性能低于丙烯酸和聚丙烯酸板的机械性能,但其性能却比便宜的黑色沥青饱和纸板板的机械性能好得多。因此,它们是用作低成本临时屋顶的好选择。和黑色沥青饱和纸板。因此,评估了自然风化对不同类型片材的最大拉伸撕裂力和最大挠曲载荷的影响。尽管WPC板的机械性能低于丙烯酸和聚丙烯酸板的机械性能,但其性能却比便宜的黑色沥青饱和纸板板的机械性能好得多。因此,它们是用作低成本临时屋顶的好选择。它们的性能比廉价的黑色沥青饱和纸板板要好得多。因此,它们是用作低成本临时屋顶的好选择。它们的性能远远优于廉价的黑色沥青饱和纸板。因此,它们是用作低成本临时屋顶的好选择。
