jäätymisenestoa

Jäätymisenestoa, also known as antifreeze, is a substance used to prevent or delay the freezing of a liquid, typically water, by lowering its freezing point. It is commonly used in automotive cooling systems, where it prevents the engine coolant from freezing in cold temperatures. Antifreeze works by inhibiting the formation of ice crystals, which disrupts the normal freezing process.

The most common type of antifreeze is ethylene glycol-based, which can lower the freezing point of water to as low as -50 degrees Celsius. Other types include propylene glycol-based antifreeze, which is less toxic but less effective, and methanol-based antifreeze, which is highly toxic but effective at very low temperatures.

Antifreeze is typically mixed with water in a specific ratio, usually 50:50, to achieve the desired freezing point depression. It is important to use the correct type and concentration of antifreeze for the intended application, as using the wrong type or concentration can cause damage to the system.

In addition to automotive use, antifreeze is also used in other applications where freezing is a concern, such as in industrial cooling systems, refrigeration systems, and even in some types of food preservation. However, it is important to note that antifreeze is toxic to humans and animals, and should be handled with care.
