润滑剂

The result shows that the viscosity was improved with the increase of the molecular mass of the product, the viscosity at 100℃ was between 17.827.6 mm^2/s, the viscosity index was more than 125, solidifying point was below -27℃, the oxidative stability was also improved with the increase of the molecular mass of the product. The biodegradabilities of complex esters were more than 70%. The value of PB was 784 N, the value of wear diameter was 0.41 mm, the temperature of thermal decomposition was above 250℃. The complex esters can be used as excellent green lubricants.

结果表明，复合酯的粘度随着分子量的增大而增大，粘度指数大于125，凝点低于－27℃，氧化稳定性随分子量的增大而提高，生物降解率＞70%，最大无卡咬负荷为784N，磨斑直径0.41mm，热分解温度＞250℃，因此目标产物是性能良好的绿色润滑剂。

Therefore, remember to change oil in the oil pan and air compressor into winter-use oil when winter comes; change gear oil in the transmission, transfer case, differentials and steering gear into winter-use oil, after cleaning the hub bearing; add bearing lubricants of low viscosity; change into winter-use oil with low solidifying point, for diesel engines in the severe cold area.

因此记住当冬天来临时要把承油盘和空气压缩机里的油换成冬天用油；在清洁完轮毂螺栓后，把在传送装置、变速箱、差动齿轮和操纵装置中的齿轮油换成冬天用油；加入低粘度的轴承润滑剂；对于处于非常寒冷的地区的柴油发动机，冬季用油要有较低的凝点。
