高强陶粒在混凝土中的吸水率低于其在水中的吸水率，且高强陶粒在混凝土中的吸水率要受到混凝土水灰比的影响，水灰比越大，吸水率越大；水灰比越低，吸水率随压力和受压时间的变化越不明显。 | | 7. | 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
试验结果表明：所选原料的尺寸、形状及纯度可满足固体润滑剂的性能要求；聚四氟乙烯树脂热分解温度超过400 ，但在ptfe中加入无机填料会使复合材料吸水率提高，熔融温度及分解温度降低，且伴有氧化分解反应；碳纤维表面含有c = o及c - o - c等极性基团，有利于提高其与其它组分的相容性，提高层间剪切强度；均匀设计试验方法能够用较少的试验次数找出配方与摩擦性能间的关系，拟合曲线基本能表示各配方的摩擦系数发展趋势；配方中不加铜粉或不加石墨，其摩擦系数均较高，说明铜粉和石墨应该配合使用；当铜粉15份、石墨60份时，铜粉30份、石墨30 - 40份时，铜粉60 、石墨15 - 30份时，摩擦系数均具有较低值；纯聚四氟乙烯树脂在空气冷却时结晶度最大，磨损量也是三者中最大的；同时，固体润滑剂试样在空气冷却时的磨损量也是三者中最大的：不论是固体润滑剂与45 #钢轴配副或是固体润滑剂镶嵌入铜套后与gcr15钢轴配副，在金属表面均可形成润滑转移膜，从而减少金属摩擦副表面间的直接接触，大大延长其使用寿命;转移膜中主要含有较多的石墨、少量聚四氟乙烯、 moo 。 |
