Antifreeze is a coolant that contains special additives and is mainly used in liquid-cooled engine cooling systems. In addition to antifreeze, antifreeze also has the following advantages: Anti-corrosion function: The engine and its cooling system are made of metal, including copper, iron, aluminum, steel and solder. When these metals come into contact with water at high temperatures, they corrode and rust over time. Antifreeze will not cause corrosion to the engine cooling system, but also has anti-corrosion and rust removal functions.
General use: used as coolant in cooling systems of automobiles, trains, diesel locomotives, tractors, ships, engines, water tanks and various mechanical equipment, diesel engines, gasoline engines, etc. It has the functions of anti-freezing, anti-boiling, anti-corrosion and anti-scaling. The boiling point of water is 100°C, while the boiling point of high-quality antifreeze is usually 110°C above zero, so summer antifreeze is more difficult to boil than water. Using water as coolant, the biggest headache for drivers is scale. Scale adheres to the metal surface of the tank and water jacket, making the cooling effect worse and worse, and it is also difficult to remove. High-quality antifreeze is made of distilled water and anti-scaling additives are added, which not only does not produce scale, but also has a descaling effect. Of course, if your tank is heavily scaled, it's best to rinse it thoroughly with tank cleaner before adding antifreeze. Like water, it has the advantages of large specific heat, high latent heat of evaporation, and convenient water replenishment. When the ambient temperature is below zero, the water in the cooling system will freeze, and the components of the cooling system are in danger of expansion and damage. At this time, the use of antifreeze can ensure the normal operation of the engine at low temperatures.
With the improvement of engine structure and the advancement of material technology, a notable feature of modern automobile engines compared with old-fashioned engines is that the operating temperature of modern engines is high, and the upper limit of normal operating temperature is generally above 100 °C. If all the water is injected, when the engine temperature reaches 100°C, the water will boil and "boil". In addition, water is corrosive and will generate scale, which will affect the cooling effect. Therefore, it is necessary to use a special cooling medium - antifreeze. Protective effect: 1. It has anti-corrosion protection effect on cooling system components. 2. Prevent scaling and avoid reducing the heat dissipation effect of the radiator. 3. Make sure the engine can work within the normal temperature range. Therefore, the engine antifreeze must have the characteristics of antifreeze, anti-boiling, anti-corrosion, anti-scaling, and non-foaming, and is not affected by seasons and regions. Among them, freezing point and boiling point are the basic indicators of antifreeze.
There are two main points to measure the pros and cons of antifreeze: the first is the antifreeze effect, the freezing point of water is 0°C, the general antifreeze can reach -40°C, and the high-quality antifreeze should reach -60°C. This is an important indicator for calibrating the quality of antifreeze; the other is the boiling point of antifreeze, the boiling point of water is 100°C, and the antifreeze must be at least 108°C, that is to say, the lower the freezing point, the higher the boiling point, and the temperature difference between them. The larger the value, the better the quality of the antifreeze.
