汽车防冻液再生使用的研究

Study on Regeneration of Automobile Antifreeze

将备好的试验用乙二醇型防冻液用于同一款汽车冷却系统,选取不同地区具有明显温差的车辆进行试验,防冻液冰点分别是-15℃、-25℃、-35℃、-45℃,试验结束后,取出汽车更换出来的乙二醇型不同冰点防冻液为-15℃、-25℃、-35℃、-45℃依次进行处理,参照国标GB 29743-2013^([1])标准,研究经过处理后的防冻液各项理化指标能否达到该标准。

Prepared test with ethylene glycol antifreeze used in the same car cooling system, the selection of different areas has obvious temperature difference, the experiments of vehicle antifreeze freezing point respectively is 15℃, 25 ℃, 35 ℃ and 45 ℃, after the test, take out the car to replace the ethylene glycol type of different freezing point of antifreeze for 15℃, 25 ℃, 35 ℃ and 45 ℃ in turn, Follow the standards of GB 29743-2013[1], the after processing of antifreeze can the physical and chemical indexes reach the standard.
