佛山南海长城聚脲JZ润滑脂-美孚液压油经销

　　聚脲基润滑脂耐高温，在高温下不滴油，不结焦，且氧化安定性好。聚脲润滑脂具有较高的滴点，使用温度范围宽，例如为-20℃～160℃，短期可至180℃[4][6]，在较宽的温度变化范围内稠度变化小，高温下锥入度变化最小[4]。

　　聚脲基润滑脂润滑性能优越，在高温、高速、有害介质、重负荷冲击条件下工作时，仍保持轴承的良好润滑，并具有良好的极压抗磨性能，适用于高负荷环境[6]。

　　聚脲基润滑脂抗水性好，在接触大量水和水蒸气条件下工作，不流失、不乳化，同时抗酸、碱介质和辐射性能强，遇酸、碱、辐射不流失、不变质，具有良好的介质稳定性、抗辐射性、抗酸性气体介质能力和胶体安定性，在高温下分油量最小[Polyurea grease is heat-resistant, does not drip or coke at high temperatures, and exhibits excellent oxidation stability. It has a high dropping point and a wide operating temperature range, such as -20°C to 160°C, and can temporarily withstand up to 180°C [4] [6]. Within a broad temperature range, its consistency changes minimally, and the penetration changes are smallest at high temperatures [4].

　　Polyurea-based grease exhibits superior lubrication performance, maintaining effective bearing lubrication under high temperatures, high-speed conditions, harsh media exposure, and heavy-load impact scenarios. It also demonstrates excellent extreme-pressure wear resistance, making it suitable for high-load environments
