Jäätymissuojausaine

Jäätymissuojausaine, also known as antifreeze or coolant, is a liquid additive that lowers the freezing point of water and raises its boiling point. This dual function makes it essential for protecting engines and other mechanical systems from extreme temperatures. The primary purpose of jäätymissuojausaine is to prevent water from freezing in cold weather, which can cause significant damage through expansion. Simultaneously, it prevents water from boiling in hot weather, which can lead to overheating and system failure.

The most common active ingredient in jäätymissuojausaine is ethylene glycol or propylene glycol. These glycols are mixed with water, typically in a 50/50 ratio, to achieve the desired freezing and boiling point depression. In addition to glycols, modern jäätymissuojausaine formulations often contain corrosion inhibitors and other additives. These components protect the various metal parts within an engine or cooling system from rust and other forms of degradation. Different types of jäätymissuojausaine exist, often categorized by their chemical composition and the type of corrosion protection they offer, such as conventional, hybrid, and organic acid technology (OAT) coolants.

The selection of the correct type of jäätymissuojausaine is crucial for optimal performance and longevity of the system it protects. Using the wrong type can lead to reduced efficiency or even damage. It is typically found in the cooling systems of vehicles, industrial machinery, and solar thermal systems. Regular maintenance and checking the concentration of the jäätymissuojausaine are recommended to ensure it maintains its protective properties.
