| 7. | Especially , the volume content of carbon fibers has been reduced from previous 1 . 5 % ~ 2 % to 0 . 73 % ( with 20 % silica fume ) . this content results in a substantial decrease in the cost of conductive concrete 尤其是将其碳纤维体积含量由原来的1 . 5 2降到了目前的0 . 73左右(加20硅灰) ,较大幅度地降低了导电混凝土的制造成本。 |
| 8. | When vgcf volume content is low in cpe / pzt / vgcf composite , the existence of pzt can improve the vgcf distribution in cpe matrix , but the existence of pzt blocks the networks of vgcf when vgcf content is high ( 2 )通过对cpe / pzt / vgcf复合材料动态机械性能的测试结果表明, vgcf的体积分数当处于半导区时具有更为显著的压电导电减振作用效果。 |
| 9. | The relevant experiments illustrates a . c . power is more suitable for deicing or snow - melting than d . c . silica fume can improve the dispersion of carbon fibers and then reduce the electrical resistivity of carbon fiber cementious composites . at a certain volume content , when the ratio of cement , sand and stone is l : l : 2 ( by weight ) , the properties of the cfrc is the best on the whole . ( 4 ) a self - adaptive fuzzy controller is designed to finish the total control procedure after considering all kinds of factors 大量实验研究发现:采用交流电是碳纤维导电混凝土用于融雪化冰时的最佳电源选择;采用硅灰能较好地提高碳纤维在基体中的分散性,有效降低碳纤维水泥基复合材料的电阻率;并在现有的级配比实验中发现了具有最好综合性能的配比,即在相同的纤维体积含量的情况下,导电混凝土的具有最好综合性能的配比是水泥、砂子、石子的重量比为1 : 1 : 2 。 |
| 10. | Slurry erosion tests were carried out with the manufactured test apparatus in order to study the erosion properties of the polyurethane composites . the results show that the wear resistance of silicon dioxide reinforced polyurethane composites decreased with the increased amount of particles , and the wear resistance of the alunima reinforced polyurethane composites first increased but then decreased . the wear resistance of the alunima reinforced polyurethane composites processed with kh550 coupling agent were maximum at the volume content of 15 % 试验结果表明,聚氨酯复合材料的冲蚀磨损性能随白碳黑体积分数的增大而降低,随al _ 2o _ 3颗粒体积分数的增大先升高而后降低;经过偶联剂kh550处理的al _ 2o _ 3颗粒增强复合材料耐磨性比经过kh560处理的复合材料高;经过偶联剂kh550处理的al _ 2o _ 3颗粒增强复合材料在体积分数为15时具有最佳的冲蚀磨损性能。 |
