交联点 meaning in English
cross-linking point
cross-linking set
crosslinked point
Examples
- Standard test method for determination of percent devulcanization of crumb rubber based on crosslink density
基于交联点密度的粒状生胶脱硫百分比测定的标准试验方法 - Silylate - terminated polyurethanes with built - in hydrophilic sites were synthesized . when the polymer is dispersed in water , the silane alkoxy end - groups of the polymer undergo hydrolysis , followed by condensation to form a stable cross - linked aqueous dispersion . tem studies indicated that with more incorporation of hydrophilic sites , the particle size of the dispersion decreased . it was also found that the film property depended on the particle size when the crosslinking density in particels was much higher . the average molecular weight of the elastically effective network chain mc measured by swelling experiments shows fairly good agreement with the theoretical value of mc . it was also found that the cross - linking density of the casting film may increase during the film formation and drying process
将硅氧烷封端的含亲水基团的线性聚氨酯预聚体分散于水中，获得稳定的聚氨酯分散体.由于硅氧基团水解、缩合，在分散体粒子内产生扩链交联反应，生成了交联水基聚氨酯分散体.透射电子显微镜研究表明分散体粒径小、分布宽.扫描电子显微镜研究了成膜结构及成膜性能与粒径的关系.溶胀实验计算获得的两交联点之间的平均分子量与理论平均分子量相符.研究还发现此分散体膜在干燥过程中可进一步交联.膜的水溶胀及机械性能表明，此分散体具有极大的工业应用价值 - However , the mechanical properties and orientation of fiber changed little . montmorillonite could also improve the thermal stability of microstructure in pet fiber . we suggest that the strong coherence of the interfaces between montmorillonite microparticles and pet restricts the motions of pet molecular chains , developing " the special continuous network structure " and effectively prohibiting the thermal shrinkage of pet fiber
此外，蒙脱土的添加也有效地提高了纤维的热尺寸稳定性，我们认为这可能是由于片层结构的蒙脱土在pet基体中类似分子网络交联点，起到了应力支承点的作用，使分子网的连续性和完善程度变好，有效抑制了纤维的热收缩。 - While in hdpe / mmt composites , mpst of the mmt aggregates are not intercalated by pe chains . moreover , the composite of hdpe - g - ydh151 ( 8phr ) / 2phrmmt formed a good crosslinking net , the mmt act as crosslinking points . consequently , the mechanical properties of this composite is good : the elongation at break impoved 29 % and tensile modulus increased 32 %
Xrd 、 sem用一1tem结果表明ydh151提高了mmt在hdpe中的剥离和分散，并且hdpe一ydh151 ( sphr ) / 2pllrmmt复合材料形成了较完善的交联网， mmt成为了类交联点的作用;因此它的力学性能达到较高的值，断裂伸长率增加了29 % ，模量提高了32 % ;而再增加mmt的量，材料的性能有所下降。
