Polyvinylether PVE has been developed as a new lubricant for alternative refrigerant. The friction and wear characteristics of PVE were studied.1.PVE was confirmed to be an excellent lubricant on estimating the friction and wear performance, solubility with HFC, resistance of capillary tube restriction, and compressor durability compared with polyolester POE and Polyalkyleneglycol PAG.2.There are two types of boundary film, adsorbed film and solidified film. The solidified film of PVE exhibited the higher load carrying ability than the adsorbed film of POE and PAG.Furthermore, additives such as fatty acids largely ineffective with POE improved the friction and wear characteristics with PVE.3.The decrease in lubricant viscosity by dissolved HFC134a made the wear characteristics worse. The viscosity reduction decreased with an increase in the ratio of solubility of HFC134a to the mean molecular weight of lubricant.4.With polar lubricants POE and PAG adhesion between Al-Si alloy and mated steel occurred, and transfer of the Al-Si alloy to the steel was promoted. In HFC134a fluorides were formed on Al -Si alloy surfaces The fluorides had an ability to prevent wear.

聚乙烯醚PVE已被开发为替代制冷剂的新型润滑剂。研究了PVE的摩擦磨损特性。1.与多元醇酯POE和聚亚烷基二醇PAG相比，在摩擦磨损性能、与HFC的溶解性、抗毛细管限制性和压缩机耐久性方面，PVE被证实是一种优异的润滑剂。2.边界膜有吸附膜和固化膜两种类型。 PVE的固化膜比POE和PAG的吸附膜表现出更高的承载能力。此外，对POE基本上不起作用的脂肪酸等添加剂改善了PVE的摩擦磨损特性。3.溶解的HFC134a导致润滑剂粘度降低，使磨损特性变差。粘度降低随着HFC134a溶解度与润滑剂平均分子量之比的增加而减小。4.极性润滑剂POE和PAG在Al-Si合金与配合钢之间发生粘附，并促进Al-Si合金向钢的转移。在HFC134a中，氟化物在Al-Si合金表面形成，氟化物具有防止磨损的能力。
