| 1. | Expose cylinders to corrosive materials such as ice melting compounds
把钢瓶暴露于腐蚀性材料，如冰熔化的化合物。 |
| 2. | However , when aa content exceeded 10wt . - % , the increment of the extent of grafting level off and the grafting efficiency decreased remarkably . afterward hdpe - g - aa / mmt composites and hdpe / mmt composites were prepared via melt compounding
然后用十八烷基季胺盐处理过的钠基蒙脱土( mmt )分别与hdpe以及hdpe - g - aa熔融插层后制备了两种复合材料。 |
| 3. | Exfloited nanocomposites were successfully synthesized . the study of melting compound about pet eva abs pvc cpe and montmorillonite has been carried out . we abtained several intercalated nanocomposites , tem shows the interlayer spacing is no more than 100nm
首次对pet 、 eva 、 abs 、 pvc 、 cpe 、 pp与蒙脱土熔融复合进行了研究，制得多种插层型纳米复合材料， tem照片显示：多数粘土片层的厚度在100nm以内。 |
| 4. | Owing to the abundant output and broad applications of poiyolefine , pls nanocomposites based on poiyolefine have become an enormous commercial allure . the studies on the melt compounding of polymer / compatibilizer - layered silicates system and their structure and properties were carried out
提出聚合物粘土( pls )纳米复合材料的阻隔几何模型，推导出适合pls纳米复合材料体系的相对透气性公式，并探讨影响透气性的各种因素。 |
| 5. | Moreover when aa content exceeded 10wt . - % , the increment of the extent of grafting level off and the grafting efficiency decreased remarkably . then hdpe - g - ydh151 / mmt composites and hdpe / mmt composites were prepared via melt compounding . ftir proved that there were interactions between ydh151 and mmt sheets
接着用十八烷基季胺盐处理过的钠基蒙脱土分别与hdpe以及两种hdpe一物h151熔融插层后制备了三种复合材料，研究了mmt和ydh151间的相互作用对分散和性能的影响。 |
| 6. | Preparation , structure and properties of hdpe ~ g ~ aa / mmt nanocomposites melt grafting reaction of hdpe with aa was performed in thermohaake rheomix and hdpe - g - aa with high grafting degree and high grafting efficiency was prepared . the change of torque indicated that the graft copolymerization was existed during melt compounding . the extent of grafting was analyzed by ftir and element analysis
在hdpe中只加过氧化二异丙苯( dcp )时，由于发生交联反应而使平衡扭矩明显增加，熔点和结晶度降低，加入aa后， aa与hdpe的接枝和hdpe自身的交联并存，前者对后者有抑制作用，从而使扭矩下降，熔点和结晶度部分恢复。 |
| 7. | In this paper , high density polyethylene / bentonite nanocomposites were prepared by simple melt compounding , their structures were demonstrated with x - ray diffraction , ft - ir spectra and dta . it was proved that the molecular chain of pe could be intercalated in layered silicate of organobentonite ， the intercalation nanocomposites were obtained
