graft ratio meaning in English
接枝率
Examples
- When the graft ratio was high , the hydrophilic side chain was long and the molecular mass of the main chain of the hydrophilic matrix was great , the diffusion of pp - g - peg in pp blends would be poor , and the diffusion coefficient would also be small
接枝率越高、亲水性侧链的长度越长，亲基体主链摩尔质量越大，接枝共聚物在聚丙烯共混体系中的迁移扩散性能越差，扩散系数越小。 - The factors that affect on graft ratio are discussed . the factors include reactive temperature , reactive time , the dosage of initiating agent and the dosage of maleic anhydride etc . . the optimum reactive condition and the optimum reactive compounding formula are gotten
在本课题研究过程中，首先制备了pe - mah ，讨论了反应温度、反应时间、引发剂的用量和酸酐用量等对接枝率的影响，得出了最佳反应条件和最佳反应配方。 - The surficial modification based on the free radical and the polar which was initiated by radiation . and we proceed to study the preradiation and coradiation grafting and surfacial grafting on the uhmwpe fiber under the electron beam . the grafting monomer were aa , am , st , mma . then we applied grafting ratios sem , ft - ir , dynamic wetting to represent the result of grafting
本文分别采取预辐照和共辐照接枝方法进行了纤维辐照接枝丙烯酸、丙烯酰胺、苯乙烯、甲基丙烯酸甲酯的研究，并运用测算接枝率、 sem 、红外光谱以及纤维浸润性测试等方法对接枝效果进行了表征，并据此分析了影响表面接枝效果的主要因素。 - The experiment result discovered the grafting effect of crylic acid and acrylamide were obvious which can be proved by the sem photoes . by the ft - ir testing of the grafted uhmwpe fabric , we discovered that some new polar groups were introduced to the surface . then by the dynamic wetting experiment of the grafted uhmwpe fabric , we concluded that the wetting time was a parabola relation with the graft ratio and the wetting time of the grafted uhmwpe fabric was less than that of untreated fabric . the results showed that after the coradiation grafting , uhmwpe fiber ' s surficial nonreactivity could be improved effectively
通过对接枝uhmwpe织物的红外光谱分析，发现其表面引入了许多新的极性基团。最后运用了纤维动态浸润性分析了接枝后的效果，得到所测浸润稳定时间与接枝率成抛物线关系，而且接枝样品的浸润稳定时间都比未处理样品的浸润稳定时间小些，这说明了共辐照接枝的方法可以有效地改善uhmwpe纤维表面惰性，达到uhmwpe纤维表面改性的目的。
