辐照接枝 meaning in Chinese
irradiation grafting
Examples
- Effect of - ray irradiation on the surface performance of carbon fiber
射线辐照接枝对碳纤维表面性能的影响 - Study on modification of polyvinylidene fluoride ultrafiltration membranes by co - 60 irradiation grafting
聚偏氟乙烯超滤膜的辐照接枝改性研究 - 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。
