What are the functions of antifreeze?

Corrosion protection: The engine cooling system is made of various metals, such as copper, iron, aluminum, steel and solder. Long-term exposure to high-temperature water will lead to rust and corrosion of these metals. However, using high-quality antifreeze can avoid this problem, and it also has the function of anti-corrosion and rust removal. High boiling point: the boiling point of water is only 100 degrees, while the boiling point of high-quality antifreeze coolant is usually above zero 1 10 degrees, so antifreeze is less likely to boil than water in hot summer. Anti-scaling: When water is used as coolant, the scale problem often occurs. The scale will adhere to the metal surface of water tank and water jacket, which makes the heat dissipation effect worse and worse, and it is often difficult to remove the scale. The high-quality antifreeze is made of distilled water mixed with anti-scaling additives, which will not only produce scale, but also play a role in scale removal.
