polar fiber 中文意思是什麼
polar fiber
解釋
極纖維-
The results indicated that the dimension, shape and purity of base material could meet the functional demand of solid lubricant ; the thermal decomposition temperature of ptfe resin exceeds 400 c, but organic and inorganic packing filler added in ptfe made the water absorption rate of composite material increased, melting temperature and decomposition temperature decreased, in the meanwhile oxidative decomposition reaction was accompanied ; polar groups such as c = o, c - o - c and so on in the carbon fiber surface is advantageous to increase compatibility with other components and interlayer shearing strength ; uniform design experimental method could help to find the relationship between formula and frictional property by relatively small tests. the developing trend of each formula ' s friction coefficient could be showed by fitting curve ; the friction coefficient with no copper powder or graphite in formula was relatively big. this fact showed that copper powder and graphite should be used cooperatively ; it was found that when the ratio of copper powder to graphite by weight is 15 : 60, 30 : 30 - 40 and 60 : 15 - 30 respectively, the friction coefficient was relatively small. the degree of crystallinity of pure ptfe reached maximum by air cooling and the abrasion loss also reached maximum among three ones ; at the same time, the abrasion loss of solid lubricant sample was also the biggest among three ones ; when solid lubricant matched with 45 # steel axle or gcrl5 steel axle, lubricant transfer film could be formed on metal surface, thus direct contact between the surface of metal friction pair rings was reduced. their working life was elongated extremely ; there was mainly much graphite, a little ptff, moo3, feso4, cus and so on in lubricant transfer film
試驗結果表明：所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求；聚四氟乙烯樹脂熱分解溫度超過400 ，但在ptfe中加入無機填料會使復合材料吸水率提高，熔融溫度及分解溫度降低，且伴有氧化分解反應；碳纖維表面含有c = o及c - o - c等極性基團，有利於提高其與其它組分的相容性，提高層間剪切強度；均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系，擬合曲線基本能表示各配方的摩擦系數發展趨勢；配方中不加銅粉或不加石墨，其摩擦系數均較高，說明銅粉和石墨應該配合使用；當銅粉15份、石墨60份時，銅粉30份、石墨30 - 40份時，銅粉60 、石墨15 - 30份時，摩擦系數均具有較低值；純聚四氟乙烯樹脂在空氣冷卻時結晶度最大，磨損量也是三者中最大的；同時，固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的：不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副，在金屬表面均可形成潤滑轉移膜，從而減少金屬摩擦副表面間的直接接觸，大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。 -

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
本文分別採取預輻照和共輻照接枝方法進行了纖維輻照接枝丙烯酸、丙烯酰胺、苯乙烯、甲基丙烯酸甲酯的研究，並運用測算接枝率、 sem 、紅外光譜以及纖維浸潤性測試等方法對接枝效果進行了表徵，並據此分析了影響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 poor adhesion of non - polarity ultra - high molecular weight polyethylene ( uhmwpe ) fiber with commonly polar resin matrix limits its applications in structure composites. in order to improve adhesion of uhmwpe fiber with matrixs, three methods are explored in this work, which are uhmwpe fiber surface treatment, synthesizing ve resin and introducing carbon fiber to co - hybrid with uhmwpe fiber
論文針對超高分子量聚乙烯（ uhmwpe ）纖維粘接性差，沒有合適的既能與之獲的良好粘接界面又可以獲得良好結構強度的樹脂基體的問題，展開了纖維表面的鉻酸氧化處理、合成ve樹脂以及採用碳纖維進行混雜三種途徑的研究。
