hard-segment

基本解释

Nano-montmorillonite-aliphatic PU elastomer synthesized from HMDI, PTMG1000 and MMT2 with 40% mass fraction of hard segment possesses better mechanical properties.
以HMDI、PTMG1000和MMT2为原料,硬段质量分数为40%25时,所合成的纳米蒙脱土-脂肪族聚氨酯弹性体具有较好的力学性能。
The effects of hard segment content on the microstructure and viscosity of polyether PU and PUU were studied by FT-IR, DSC, viscosimeter.
利用FT-IR,DSC,旋转黏度计研究了硬段含量对聚醚型PU和PUU的微观结构及黏度的影响。
It's caused by the micro phase separation degree of TPU is increased as well as the soft hard segment structure is perfected.
研究认为热处理提高了TPU的微相分离程度,完善了TPU中的软硬段结构。
For these PUU aqueous dispersions, the particle size decreases with the increase of the hard segment content, but their stability is enhanced.
结果表明：随硬段含量的增加，PUU水分散液的粒径减小，稳定性增加，室温贮存期大于1年；
Shape memory polyurethanes based on aliphatic diisocyanate HDI were synthesized with different hard segment contents to study the shape memory effect affected by hard segment.
以脂肪族异氰酸酯HD I为硬段原料合成了脂肪族的形状记忆聚氨酯,通过调节硬段含量研究了硬段结构对形状记忆性能的影响。
