浓缩型的用户可根据使用环境温度和发动机最高工作温度,按产品说明书选用,一般在选购和配制时,其冰点应比环境最低气温低5℃以上1.冷却液的种类(1)挥发性冷却液:含醇90%左右,冰点低,比水蒸发快,在补充冷却水时必须同时补充冷却液原液。(2)半挥发性冷却液:以甲醇或乙二醇为主要成分,性能中等,比挥发性冷却液蒸发得慢。 Concentrated users according to the use of ambient temperature and maximum operating temperature of the engine, according to product manuals, usually in the purchase and preparation, the freezing point should be lower than the minimum temperature of the environment 5 ℃ above 1. The type of coolant (1) volatile Coolant: about 90% alcohol, low freezing point, faster evaporation than water, coolant water must be added at the same time to supplement the coolant liquid. (2) semi-volatile coolant: methanol or ethylene glycol as the main component, medium-performance, evaporation than the slow evaporation of volatile liquid.
