extent of grafting造句
例句與造句
- When aa content was less than 10wt - % , the extent of grafting increased with increasing the content of aa , and the grafting efficiency maintained in a high level of about 80 %
在aa含量低于10時(shí)，接枝效率可以保持在80以上； aa含量太多時(shí)易產(chǎn)生自聚，使接枝效率大幅度下降。 - 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鹽處理過的鈉基蒙脫土( mmt )分別與hdpe以及hdpe - g - aa熔融插層后制備了兩種復(fù)合材料。 - The extent of grafting was analyzed by ftir and element analysis and thermal properties of hdpe - g - ydh151 were studied by dsc measurement . when adding dcp to hdpe , the melting temperature and the degree of crystallization of the matrix decreased because of the crosslinking reaction of hdpe
而且mmt的加入，降低了hdpe - g - aa的熔融溫度和結(jié)晶度，這主要是因?yàn)閯冸x后的mmt在一定范圍內(nèi)限制了pe鏈的運(yùn)動(dòng)，從而降低了基體的結(jié)晶能力。 - 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
接著用十八烷基季胺鹽處理過的鈉基蒙脫土分別與hdpe以及兩種hdpe一物h151熔融插層后制備了三種復(fù)合材料，研究了mmt和ydh151間的相互作用對(duì)分散和性能的影響。 - 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中只加過氧化二異丙苯( dcp )時(shí)，由于發(fā)生交聯(lián)反應(yīng)而使平衡扭矩明顯增加，熔點(diǎn)和結(jié)晶度降低，加入aa后， aa與hdpe的接枝和hdpe自身的交聯(lián)并存，前者對(duì)后者有抑制作用，從而使扭矩下降，熔點(diǎn)和結(jié)晶度部分恢復(fù)。 - It's difficult to find extent of grafting in a sentence. 用extent of grafting造句挺難的
