Jäätymissuojaaine

Jäätymissuojaaine, also known as antifreeze or coolant, is a substance added to liquids to lower their freezing point and raise their boiling point. Its primary function is to prevent liquids from freezing in cold temperatures, which can cause damage to systems like car engines, plumbing, and solar panels. Conversely, it also helps to prevent overheating by increasing the boiling point of the liquid, allowing it to absorb and dissipate heat more effectively.

The most common type of jäätymissuojaaine is based on ethylene glycol or propylene glycol. These glycols are miscible with water and form solutions with significantly altered freezing and boiling points. Ethylene glycol is highly effective but also toxic. Propylene glycol is less toxic and often preferred for applications where accidental ingestion is a concern, such as in food processing equipment or recreational water systems.

Beyond glycols, other substances can act as jäätymissuojaaine, though they are less common in widespread industrial or domestic use. These might include alcohols like methanol or ethanol, or salts. The specific type of jäätymissuojaaine used depends on the application, required temperature range, safety considerations, and cost. Proper maintenance and regular checks of the concentration of jäätymissuojaaine in a system are crucial to ensure its effectiveness and prevent potential issues.
