jäänpoistoaine
Jäänpoistoaine, also known as de-icer, is a chemical substance used to melt ice or prevent its formation on surfaces such as roads, sidewalks, and aircraft. The primary mechanism of action for most jäänpoistoaine is to lower the freezing point of water. When mixed with water, these compounds create a solution that remains liquid at temperatures below the normal freezing point of pure water.
Commonly used jäänpoistoaine include salts like sodium chloride (rock salt), calcium chloride, and magnesium chloride. Calcium
The application of jäänpoistoaine can have environmental consequences. Runoff containing de-icing salts can contaminate soil and
