jäätymisenestoaine

Jäätymisenestoaine, also known as antifreeze, is a chemical additive that lowers the freezing point of liquids. Its primary function is to prevent water-based solutions from freezing, which can cause damage to pipes, engines, and other systems. The most common type of antifreeze is ethylene glycol, which is mixed with water to create a solution with a significantly lower freezing point than pure water. This mixture also typically has a higher boiling point, providing a dual benefit of freeze and overheat protection.

Antifreeze is widely used in automotive cooling systems to prevent the coolant from freezing in cold weather and to prevent it from boiling over in hot weather. It also contains corrosion inhibitors to protect metal components within the cooling system from rust and degradation. Other applications for antifreeze include de-icing aircraft wings and runways, as well as in heating and cooling systems in buildings. While ethylene glycol is prevalent, other substances like propylene glycol are also used, often for applications where toxicity is a concern, such as in food processing or recreational water systems. Proper maintenance and timely replacement of antifreeze are crucial for optimal performance and longevity of the systems it protects.
