Examples
- Nanocrystal pvc and nanometer caco3 is applied in profile and tube . production . the properties of profile and tube are studied in various content of nanocrystal pvc and nanometer cac03
将纳米晶pvc与纳米caco _ 3母料应用于pvc型材生产中，研究了纳米晶pvc和纳米caco _ 3对体系性能的影响。 - The result show that pp filled with nano - particles has better mechanical performances than which filled with micron - particles . there is some furthest dosage of titanate coupling agent in cac03 / pp
但是当掺入量较大时，由于团聚现象的大量出现，导致各项力学强度随着掺入量的增加而降低。 - In this thesis we have studied the toughening and strengthing modifications of polypropylene ( pp ) by nano - particle such as cac03 ) si02 and ti02 . the performance of modified polypropylene and the modifying mechanism have been introduced . we have also explored the furthest dosage of titanate coupling agent in cac03 / pp and the influence of coupling agent to the composites by the determination of the mechanical properties
本课题主要研究纳米caco _ 3 、 sio _ 2和tio _ 2粉体改性聚丙烯( pp )后材料的力学性能及其增强机理，同时还对钛酸酯偶联剂改性纳米caco _ 3粒子的最佳含量以及偶联剂的加入对复合材料的力学性能的影响进行了研究，并对纳米caco _ 3粒子和微米caco _ 3粒子分别填充pp的力学性能进行了比较分析。 - Furthermore , we compared the mechanical properties between the modified nano - cac03 / pp and unmodified nano - cac03 / pp . we have investigated the composites by means of mechanical testing , dsc , xrd , ft - ir , tem , sem , etc . the relation between the structure and property of the composites has been discussed in this thesis . we studied the nano - particles by means of ls particles size analysis , we also studied the modified nano - cac03 by means of ft - ir
论文中对caco _ 3粒子进行了粒度与比表面测试分析，对经钛酸酯偶联剂表面改性的纳米caco _ 3粒子进行了红外吸收光谱分析，对改性后的复合材料进行了力学性能测试、差热扫描量热分析、 x射线衍射谱、红外吸收光谱、透射电镜、扫描电镜等分析，讨论了样品中结构和性能之间的关系。 - The mechanical properties of the modified nano ~ cac03 / pp is better than that of unmodified nano - cac03 / pp , especially the impact strength has been improved greatly . but when the dosage of nano - particles is too much , those nano particles will accumulate and this will lead to decreasing of strength of the material . through investigated of xrd and dsc , we found that ? - pp was formed by addition of nano - particles
通过xrd和dsc分析发现，纳米粉体对- pp有诱导生成作用：通过sem分析发现表面改性后的纳米粒子填充即后，与pp基体结合较好，基体在冲击方向存在层状滑移，并有纤维状形变，显示基体发生了剪切屈服形变。
