【求助】求助翻译毕业论文英文摘要
|
|||
|
哪位能帮我翻译下毕业论文英文摘要下，明天就要交定稿了，急！！！10金币，谢谢！！！！！ 木塑复合材料是一种绿色环保材料，该材料可代替木材使用，能有力地缓解我国森林资源贫乏所造成的窘境，具有广阔的市场前景、良好的经济效益和社会效益，越来越受到人们的关注。但是极性的木粉与非极性的塑料之间的相容性较差，影响了木塑材料的加工及性能。 在对国内外木塑材料的研究进展进行了全面的综述的基础上，采用PVC、ABS和棉花秸秆为主要原料，加入相容剂EVA-g-MAH以及稀土改性的相容剂，按照不同配比共混，注塑得到木塑复合材料。通过改变体系中棉花秸秆比例及相容剂含量，探讨体系力学性能的变化，以确定综合性能优良的复合材料的配方。 实验结果表明：随含丙烯酸稀土相容剂添加量的增加，复合材料的拉伸强度下降而冲击强度在小于2份时提高；当棉花秸秆粉添加量为50份时，复合材料的综合性能最好；继续增加棉花秸秆粉的含量各性能有所下降；当棉花秸秆粉的添加量为50份相容剂添加量为6份时，复合材料最易加工；当棉花秸秆粉的添加量为40份相容剂添加量为6份时，制品的表面较光洁，随着棉花秸秆粉添加量的增加，制品表面变得粗糙，光洁度有所下降。 |

Wood-plastic composite material is a green material, the material can be used instead of timber that can effectively alleviate the poverty of China's forest resources caused by the dilemma and has broad market prospect and good economic and social benefits, more and more people attention. But the polarity of the wood plastic and non-polarity of the compatibility between the poor and the impact of the wood processing and properties of materials. In wood-plastic materials at home and abroad to carry out a comprehensive research synthesis based on the use of PVC, ABS and cotton straw as the main raw materials, adding compatibilizer EVA-g-MAH as well as the compatibility of rare earth modified agent, in accordance with the different ratio of blending, injection molding wood-plastic composite materials obtained. System by changing the proportion of cotton stalks and compatibilizer content to explore the changes in mechanical properties of the system to determine the overall performance of the composite good formula. The experimental results show that: with the rare earth containing acrylate compatibilizer added increases, the tensile strength of composite materials and the impact strength decreased less than 2 hours to raise; when cotton stalks its adding 50 powder, the composite integrated the best performance; continue to increase the content of cotton stalks powder decrease the performance; when cotton stalks powder Compatibilizer its adding 50 of its adding 6, the composite materials are most vulnerable to processing; when cotton powder to add the amount of straw 40 copies of its adding compatibility agent 6, the more smooth the surface of products, with the addition of cotton stalk powder increases, the surface becomes rough products, declined finish. 可能不太准确，你自己再改改吧！ |
