jäänpoistoaineen
Jäänpoistoaine, also known as de-icer, is a substance used to remove or prevent the formation of ice on surfaces such as roads, sidewalks, and aircraft wings. These compounds typically work by lowering the freezing point of water, a phenomenon known as freezing point depression. When mixed with water, jäänpoistoaine molecules interfere with the crystalline structure of ice, making it more difficult for water molecules to arrange themselves into a solid state. This results in ice melting at temperatures below 0 degrees Celsius (32 degrees Fahrenheit).
Common types of jäänpoistoaine include salts like calcium chloride, magnesium chloride, and sodium chloride (common salt).
The application of jäänpoistoaine is crucial for maintaining safety and mobility during winter weather. On roads,
