| 2. | Structure and mechanical properties of pvc composites filled by titanate coupling agents modified nano - caco 纳米二氧化硅颗粒表面设计及其填充聚氯乙烯复合材料的性能 |
| 3. | 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。 |
| 4. | Different coupling agent and different treatment conditions have different impacts on magnet performance . it is the best using titanate coupling agents as pretreatment reagent and dimethylbenzene as solvent 不同的偶联剂使用方法得到的表面预处理效果也不同,其中,以二甲苯为溶剂的湿混法最好。 |
| 5. | Carbon black ( cb ) was pre - treated by titanate coupling agent and electrical conductive master batche ( ecmb ) for fiber were prepared by melt - extruding pre - treated cb with pet , pe and pet / pe blend 摘要将经偶联剂处理后的炭黑分别与聚酯、聚乙烯及聚酯聚乙烯共混聚合物,通过双螺杆熔融共混,制备了纤维级导电母粒。 |
| 6. | Improvement of conductivity is more distinct , for example , titanate coupling agent and stearic acid decrease its composite ' s room temperature resistivity 10l - - 102 times , as cb content is 15 % ( w / w ) 在导电性能上表现更为明显,如钛酸酯偶联剂和的硬脂酸在炭黑含量为15时,可使材料的电阻率降低1 2个数量级。 |
| 7. | Phosphorus pentoxide is usual material and reagent in chemical industry , this product is widely used in the industries of medicine , coating auxiliaries , printing and dyeing auxiliaries , anti static additive , titanate coupling agent , phosphorus oxychloride , chemical . mainly used in producing high purity phosphoric acid , used as desiccant of gas and liquid , dehydrant of organic synthesis 五氧化二磷是化学工业中常见的原料和试剂,本品广泛用于医药,涂料,印染,化工等行业,主要用于制造高纯度磷酸,用作气体和液体干燥剂,有机合成的脱水剂,以及有机磷酸酯的制备。 |
| 8. | 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。 |
