graft ratio 中文意思是什麼
graft ratio
解釋
接枝率-
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、親水性側鏈的長度越長，親基體主鏈摩爾質量越大，接枝共聚物在聚丙烯共混體系中的遷移擴散性能越差，擴散系數越小。 -
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
通過對接枝uhmwpe織物的紅外光譜分析，發現其表面引入了許多新的極性基團。最後運用了纖維動態浸潤性分析了接枝后的效果，得到所測浸潤穩定時間與接枝率成拋物線關系，而且接枝樣品的浸潤穩定時間都比未處理樣品的浸潤穩定時間小些，這說明了共輻照接枝的方法可以有效地改善uhmwpe纖維表面惰性，達到uhmwpe纖維表面改性的目的。 -
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
在本課題研究過程中，首先制備了pe - mah ，討論了反應溫度、反應時間、引發劑的用量和酸酐用量等對接枝率的影響，得出了最佳反應條件和最佳反應配方。
