| 1. | With increasing the amount of hollow glass beads , the ratio of ultramicro iron - coated hollow glass bead decreased 随着中空玻珠用量的增大,复合粒子包裹率逐渐降低。 |
| 2. | With increasing the amount of hollow glass bead , and " decreased , " increased firstly and then decreased 随着中空玻珠用量增大,声“减小,夕‘先增大后减小。 |
| 3. | The results showed : composites had better compactness than composites of ultramicro iron - coated hollow glass bead 结果表明:此复合粒子较中空玻珠/超微铁复合粒子有更好的致密性。 |
| 4. | Composites of ultramicro iron - coated hollow glass bead were in - suit prepared using atpu as surface agent by decomposing carbonyl iron in hollow glass beads and dmf mixed solution 用atpu作表面活性剂,在中空玻珠存在下“原位”热分解五羰基铁制备出中空玻珠超微铁核壳复合粒子。 |
| 5. | Composites of hollow glass bead / ultramicro iron / ep with three - layer structure were prepared by coating ep on the surface of composites of ultramicro iron - coated hollow glass bead 通过在超微铁包裹中空玻珠复合粒子表面再包裹一层ep ,制备出了中空玻珠/超微铁/ ep三层结构复合粒子。 |
| 6. | To obtain light radar wave absorbing materials , the electroless nickel plating on hollow glass beads and mica was studied . after pretreatment of coarsing , sensitivzed , activation , and reduction , the hollow glass beads and mica powders were plated with nickel 研究了在空心微珠和云母上的化学镀镍,尝试在微珠上镀镍制备轻质雷达吸波材料,发现空心微珠壁太薄,经搅拌和加热后破碎太多,但从形貌上看已经实现了表面化学镀镍。 |
| 7. | Having consulted all the available literature on the subject , according the basic principal and method of design of radar absorbing materials , composites of epoxy resin ( ep ) - coated ultramicro iron , ultramicro iron - coated hollow glass bead , and hollow glass bead / ultramicro iron / ep with three - layer structure were prepared 本文是在查阅了大量国内外文献的基础上,依据雷达波吸收材料研究的基本理论和设计方法,以羰基铁为重点研究对象,采用原位复合的方法制备环氧树脂( ep )包裹羰基铁、超微铁包裹中空玻珠以及中空玻珠超微铁ep三层结构复合粒子。 |
| 8. | The photograph of sem showed that its surface have homogenously coated with nickel , although the hollow glass beads were crashed by agitation and heating . after pretreatment and nickel plating , the dispersity of mica powders evidently improved and the infrared emissivity decreased from 0 . 85 to 0 . 43 , and has certain wave absorbability of radar 对云母的化学镀镍工艺研究中,发现经过预处理后云母表面获得了镍层,通过扫描电镜分析,镀镍后云母的分散性提高,表面状态发生了较大的变化,法向积分发射率显著降低,由0 . 85降低为0 . 43 。 |
