查询词典 crystallinity

The glass transition temperature increases and the melt temperature, crystallinity decreases with increasing the content of naphthalene moieties.

这些性质的改变是由于萘环的引入在增加了聚合物的刚性同时也降低了聚合物的有序排列能力所致。

WAXD分析显示纤维素Ⅰ保持了原来的结晶形态，但结晶度和晶区尺寸增大。

The results showed the crystallinity of the modified PET decreased with the increase of the content of NPG, but the heat shrinkability was improved obviously. Amorphous polyester material that woul...

结果表明，通过NPG共聚改性的PET的结晶能力随NPG用量的增加而降低，热收缩能力有了明显的提高；无定型区增大，获得了在通常情况下不能结晶的PET无定型材料，从而使改性PET薄膜在拉伸时保持较高的取向度，并在高于其Tg时发生解取向热收缩；拉伸温度、拉伸倍数等拉伸工艺对于聚酯薄膜的热收缩率有着显著的影响。

The results showed the crystallinity of the modified PET decreased with the increase of the content of NPG, but the heat shrinkability was improved obviously. Amorphous polyester material that would not crystallize under usual circumstances was obtained, which made the modified PET film to be able to achieve a high degree of orientation during stretching, and it was heat shrinkable when the ambient temperature was higher than its T the effects of different drawing temperature and DR on heat shrinkage of copolyester film was discussed.

结果表明，通过NPG共聚改性的PET的结晶能力随NPG用量的增加而降低，热收缩能力有了明显的提高；无定型区增大，获得了在通常情况下不能结晶的PET无定型材料，从而使改性PET薄膜在拉伸时保持较高的取向度，并在高于其T时发生解取向热收缩；拉伸温度、拉伸倍数等拉伸工艺对于聚酯薄膜的热收缩率有着显著的影响。

Through investigated ofXRD, we found that -PP was formed by P nucleator and crystallinity was improved.

可见，利用β成核剂很难使小本体PP获得良好综合力学性能。

The addition of a andβnucleator make the melting point of iPP film ascend, lamellar thickness and crystallinity increase, and elastic recovery is improved.

4α和β成核剂的加入使得iPP薄膜的熔点升高、片晶厚度和结晶度增加，弹性回复率增大。

聚丙烯；β成核剂；力学性能；结晶性能；结构形态

With the addition of a nucleator, the melting point and crystallizing temperature of iPP rise, the induction period of crystallization is shortened, the crystallizing gets faster and the crystallinity increases.

随着退火温度的升高和退火时间的延长，iPP薄膜的熔点升高、片晶厚度和结晶度逐渐增加，弹性回复率逐渐增大，拉伸强度增大，断裂伸长率减小。

In this paper POM is determined as base resin, the glassfiber and the carbon fiberare joinend to enhance, the toughener is acceded to toughen, the nucleator is entered tochange its crystallinity.

本文确定综合性能优异的POM为基础树脂，加入玻璃纤维和碳纤维增强、加入增韧剂增韧、加入成核剂改变其结晶度。

With increasing octene content the degree of crystallinity was found to decrease while the ratio of monoclinic and orthorhombic crystals increases.

拉伸对POE弹性体聚集态结构的影响不是一个单调的过程，在低拉伸比范围内，拉伸会导致结晶度的增加，而进一步增加拉伸比又会导致对结晶的破坏。

Do you know, i need you to come back

你知道吗，我需要你回来
