乙二醇——水型防冻液是近年来国内外汽车冷却系普遍采用的一种防冻液。由于它可以全年用来冷却发动机,保护冷却系统免遭腐蚀,冬季防冻夏季防沸及防止水箱结垢,所以深受司机朋友的毒睐,在使用过程中应注意以下几点: 乙二醇的表面张力比水小,极易从缝隙中漏出来。因此,使用防冻液前,必须先检查并紧固冷却系统支菅、接头等易漏的部位。 乙二酵防冻液的浓度应根据当 Ethylene glycol - water-based antifreeze is a kind of antifreeze commonly used in domestic and international automobile cooling systems in recent years. Because it can be used throughout the year to cool the engine, to protect the cooling system from corrosion, winter anti-frost summer anti-boil and prevent the tank scaling, so by the driver friend of poisoning Lai, the use of the process should pay attention to the following points: Ethylene glycol The surface tension than water is small, easily leak from the gap. Therefore, before using antifreeze, you must first check and tighten the cooling system support, joints and other leak-prone parts. Fermentation biofilter concentration should be based on when
