Nowadays there are more and more cars, and many friends have bought cars, saying that buying a car is easier to maintain. Car maintenance is a hassle. Everyone will add antifreeze to the car, especially the friends in the north who don't add antifreeze. The weather is cold and you can't get out.Everyone knows that antifreeze can prevent freezing, you canknowledgeWhat are the main components of antifreeze?
Antifreeze compositionincludeWater, glycol and various additives,antifreezeThe main ingredient is ethylene glycol, Glycol has a high boiling point and a low freezing point. The common antifreeze has a boiling point of about 106°C and a freezing point of minus 40°C. The high-quality antifreeze should be able to reach about minus 60°C and is particularly resistant to manufacturing. The freezing point of the antifreeze is also an important indicator of the quality of the antifreeze. The lower the freezing point, the higher the boiling point, the greater the temperature difference, and the better the quality of the antifreeze.
Antifreeze is literallyAntifreeze effect, In fact, antifreeze is also called coolant, andCooling effect. When the car is in use, the engine is in a high-temperature operation state. If the car engine has been working at a high temperature, the engine will be damaged or even paralyzed in a short time. The antifreeze is added to the automobile cooling system, the heat of the engine will pass through the cooling system, and the heat will be dissipated to the surroundings after the heat is reduced, which has a cooling effect and avoids boiling.
In addition to antifreeze and cooling effects, antifreeze also hasAnti-corrosion,Anti-scalingeffect. Some anti-corrosion additives are added to the antifreeze, which can prevent the metal parts of the cooling system from being corroded. Most of the dirt is formed by the ions in the water, and the water produced by the antifreeze is softened by deionization, which has an anti-scaling effect.
