Through dehumidify and microwaving discarded wood dust (木粉), and further combining it with PVC to form PVC wood-plastic composite, this essay analyzes the mechanical properties (力学性能), water absorbability (吸水性）, flexibility, and hardness of PVC wood-plastic composite. The result indicates that as the amount of wood dust increases, the flexibility of the composite made from dehumidification decreases dramatically. However, its hardness and water absorbability increases consistently. Nonetheless, the flexibility of PVC wood-plastic composite derived from the microwave method is better than that of the dehumidification method. Even more, as the amount of wood dust increases, relatively, the wood-plastic composite's flexibility increases too. When the wood dust portion reaches fifty, the flexibility reaches a maxium of 34.9 Mpa.

是这样翻没错,我加了些转折词,没关系吧？

可有一点我看得不是很明白,你前面提到,“随着木粉含量的提高,材料的拉伸强度下降很快“,後面说,微波法制得的木塑复合材料"随着木粉含量的提高，拉伸强度逐渐升高，"

所以,你前面指的“下降很快“的PVC木塑复合材料是乾燥法制得的吗?我怕翻错,确认一下。:)

本文通过干燥、微波法处理废弃的木粉并与PVC共混制备了PVC木塑复合材料.
This article describes the method of making PVC wood-plastic composited material from
disused wood-powder together with PVC, through desiccation and microwave treatment.

并对其力学性能、吸水性、拉伸强度、硬度进行了表征和分析.
It also provides the definition and analysis of the material's mechanical properties,
hydroscopicity (water absorbability) , tensile strength, hardness.

结果表明，随着木粉含量的提高，材料的拉伸强度下降很快，硬度和吸水率不断上升；
The results show that, as the content of wood-powder increases, the material's tensile
strength drops dramatically, but its hardness and hydroscopicity rise continuously.

微波法制得的木塑复合材料,较干燥法拉伸强度有较大提高.
Microwave treatment improves the material's tensile strength dramatically, compared to
desiccation treatment.

且随着木粉含量的提高，木塑复合材料的拉伸强度逐渐升高
And, with the increases of wood-powder content, the wood-plastic composited material's
tensile strength increases gradually.
(前面 说 降低, 现在又说 提高.....)

当木粉含量50份时，拉伸强度达到最大值34.9 Mpa。
When wood-powder content is 50 portions, material's tensile strength reaches the
maximum value of 34.9 Mpa.

In this paper,the wood meals/powders were treated in thedrying and microwave methods, then they were mixed with PVC toprepareaplasticizedwood-PVC composite; after that,the mechanical properties, water absorption, tensile strength and hardness of the composite were characterized and analyzed.
结果表明，随着木粉含量的提高，材料的拉伸强度下降很快，硬度和吸水率不断上升；微波法制得的木塑复合材料较干燥法拉伸强度有较大提高，且随着木粉含量的提高，木塑复合材料的拉伸强度逐渐升高，当木粉含量50份时，拉伸强度达到最大值34.9 Mpa。
The results indicate that, as the content of wood meals increases, the tensile strength of the composite decreases rapidly, while the hardness and water absorption rise continuously; the tensile strengthofplasticizedwood-PVC compositeprepared with microwave methodis significantly improved than that prepared with drying method, and, as the content of wood meals increases, the tensile strength of the composite increases gradually, and reaches its maximum value of 34.9 Mpa when the content of wood meals is 50 portions (50%?).

In this paper, through drying and microwave method processing waste wood flour and PVC blending PVC wood plastic composite material was prepared, and its mechanical properties, water absorption, tensile strength and hardness have been characterized and analyzed.Results show that with the improvement of wood powder content, the tensile strength decreased rapidly, the increase in hardness and water absorption;Microwave method, wood plastic composite materials tensile strength than dry method is improved greatly, and with the improvement of wood powder content, the tensile strength of the wood plastic composites increased, when 50 wood powder content, the tensile strength reached maximum value 34.9 Mpa.

In this paper, by drying, microwave treatment of waste wood flour and PVC wood-plastic composite materials and PVC blends were prepared, and their mechanical properties, water absorption, tensile strength, hardness characterization and analysis. The results show that, as wood flour content increased, the tensile strength drops quickly, hardness and water absorption rising; the microwave prepared WPC drier law tensile strength has improved greatly, and with the wood powder content increased, the tensile strength of the wood-plastic composite materials gradually increased, the tensile strength reaches a maximum value of 34.9 MPa when the wood flour content of 50 parts.
