结晶能力 meaning in English
crystallizing power
Examples
- 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的熔融温度和结晶度，这主要是因为剥离后的mmt在一定范围内限制了pe链的运动，从而降低了基体的结晶能力。 - The introduction of lateral rods firstly induced the decrease of crystallization ability , which resulted in the descent of melting points . further increasing the lateral rods centent resulted in the increase of polymers " melting points . but it was interesting that the solvability was enhanced all the time
横向液晶基元的引入首先导致聚合物结晶能力的下降，熔点降低；进一步增加横向液晶基元的含量，聚合物的结晶能力又逐渐增加，熔点升高，但是，聚合物的溶解性始终变好。 - The results from x - ray diffraction demonstrated that pp / mmtome was a fully intercalated nanocomposite , pp / mmtom and pp / ommt were partly intercalated nanocomposites , but the intercalation effect of pp / mmtom nanocomposite was better ; the crystallization characteristics of pure pp and pp / mmt nanocomposites were investigated by dsc , waxd and pom . the result of these testing showed that mmt nano - layers acted as nucleating agents for the crystallization of pp , the addition of mmt had effect on the crystallization process , leading the increasing of crystallization temperature crystallization rate and crystallinity , but also the dimension of spherulite reduced . but the formation of pp crystal did n ' t change , the formation of pp crystal in three pp / mmt nanocomposites and pure pp were a - form on the whole ; influences of three sorts of mmt on mechanical properties of pp / mmt nanocomposites were studied , as a result , the addition of mmt comprehensively improved mechanical properties of pp : notched impact strength , tensile strength and flexural properties were all increasing , but the extent of increasing were n ' t large
通过xrd分析比较这三种pp mmt纳米复合材料微观结构得到， pp mmt _ ( ome )属于完全插层， pp mmt _ ( om )与pp ommt的插层程度相近，但是pp mmt _ ( om )相对较好；通过对纯pp和三种pp mmt纳米复合材料的结晶性能研究发现，蒙脱土纳米片层对pp结晶产生明显的异相成核作用，结晶能力增强，使pp的结晶温度和结晶速率提高，结晶度增加，球晶晶粒细化，但是没有改变pp的结晶形态，三种pp mmt纳米复合材料的结晶形态都属于晶；通过对pp mmt纳米复合材料的力学性能测试得知，蒙脱土的加入全面提高了pp的力学性能，缺口冲击强度、拉伸强度和弯曲性能都有一定程度的提高，浙江{ _业大学硕十学位论文摘要但是提高幅度都不是很大，不过ommt 、 mmtom和mmtc ) me三种蒙脱土对pp力学性能有着不同的改性作用，其中pp / mmtom最好， pp月边mto崛次之， pp / ommt最低，这种情况主要是由蒙脱土对pp结晶性能的影响和蒙脱土的纳米改性作用造成的。 - A solid - state shear compounding technology based on pan - milling ( s3c ) has established , by which the graphite with weakly combined structure are exfoliated and then compounded with pp at nanoscale . the obtained pp / graphite nanocomposites have greatly enhanced electrical and thermal conductivity . their structures and properties were characterized by analysis of particle size and distribution , sem , tem , xrd , the electrical conductivity , the thermal conductivity and heat - decomposition temperature etc . by taking advantages of the layered inorganic fillers with a weak interaction between layers ( e . g
磨盘碾磨剪切力场使pp分子链断裂，相对分子质量减小，石墨的导热和润滑性能抑制pp的降解和粉碎，使pp / yep250 (膨胀石墨250倍)复合粉磨盘碾磨固相剪切复合技术及导电导热pp /石墨纳米复合材料的制备与性能体中， pp分子运动活性提高，结晶能力增强，为pp在熔融加工中进一步向己剥离的石墨片层间扩散，形成纳米复合结构创造了条件。
