熱電偶用補償導線電纜的作用是來延伸熱電偶的冷端，與測溫儀連接構成測溫系統，產品選用進口優質聚四氟乙烯絕緣和護套，並採用先進擠出設備新工藝流水生產線，具有耐高溫低溫，耐酸堿，防腐，耐老化等優異性能，可浸入油水中長期使用，正常工作溫度- 40 275 。After looking up a large amount of native and foreign information, the materials used in the experiment were as follows : ptfe base, graphite filler, molybdenum disulfide filler, copper powder filler, carbon fiber and so on. the experimental method is that the formula was designed according to uniform experimental method, the relationship between formula and frictional property was found with spline function and then the representative test points were chosen from fitting curve to make verification test for optimization. the preparative technique of solid lubricant is cold - press sintering method
經過查閱大量國內外文獻資料后確定原料為：聚四氟乙烯樹脂為基體，加入石墨、二硫化鉬、銅粉、碳纖維等填料；試驗方法為：根據均勻試驗方法設計配方，用樣條函數找出配方與摩擦性能的關系，然後在擬合曲線上選取具有代表性的試驗點進行驗證試驗，達到優化的目的；制備工藝：冷壓燒結法制備固體潤滑劑。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 。Fourth, the advanced surface analysis technique - x ray photoelectron spectrum is employed to study the adsorption of soluble - starch on the pvdf membrane. then we test by using xps combined with sem the original sample, the fouled sample and the washed sample with rubber sponge balls
第四，採用x射線光電子能譜（ xps ）技術分析了可溶性澱粉在聚偏氟乙烯膜表面的吸附，並將xps技術與電子顯微鏡技術相結合，對原始樣品、污染樣品和海綿橡膠球清洗樣品進行了測試和分析。The method using an improved osmotic membrane f46 ( made by ethylene polymer ) to separate gases from oil is brought forward. capability of osmotic membrane f46 is discussed too. from a great of experimentations, we get the osmotic balance curve of gases, confirm balance conversion coefficient
2 ）研究以高分子透氣膜為特徵的變壓器油在線脫氣技術；提出了一種能有效改進氣體滲透性能的聚四氟乙烯和六氟乙烯的混合膜（ f46膜）用於變壓器油氣自動分離，分析f46膜的氣體滲透性能，通過大量的試驗得出氣體滲透平衡曲線，確定油中氣體的平衡轉換系數，為實施變壓器油中氣體在線監測奠定基礎。Polytetrafluoroethylene high temperature resistant compensation lead - 40 275
