优质的防冻液,必须具备防冻、防腐蚀双重性能。因为当汽车工作时,散热器中的水在散热器和发动机缸体间往复循环流动,以达到冷却发动机的目的。由于水微带酸性,且含微量氯离子等杂质,长期在加热情况下循环,如果不添加防锈助剂容易氧化锈蚀,影响散热器等零部件的寿命。 而市上供应的汽车防冻液品种繁多,但有些商品包装上既没有表明主成份含量,又没有防锈指标。为了降低成本,有的在防冻液中掺入大量的水,充当防冻液出售,价格有时虽较名牌防锈防冻液稍低,但实际效果大大低于正常产品。
High-quality antifreeze, must have antifreeze, anti-corrosion dual performance. Because when the car is working, the water in the radiator reciprocates between the radiator and the engine block, so as to cool the engine. As water microstrip acidic, and trace impurities such as chlorine ions, long-term heating cycle, if you do not add rust inhibitor easily oxidized, affecting the life of components such as radiators. The market supply of automotive antifreeze a wide variety, but some commodity packaging neither shows the main ingredient content, there is no anti-rust indicators. In order to reduce costs, some of the antifreeze fluid mixed with a lot of water, as antifreeze for sale, although the price is slightly lower than the brand name antifreeze antifreeze, but the actual effect is much lower than normal products.
