vesiglykoliliuos

Vesiglykoliliuos, meaning "water-glycol solution" in Finnish, refers to a mixture of water and glycol, most commonly ethylene glycol or propylene glycol. These solutions are utilized for a variety of applications due to their combined properties of water and glycol. The primary benefit of mixing glycol with water is to lower the freezing point and raise the boiling point of the mixture, making it effective as an antifreeze and coolant.

The specific ratio of water to glycol in a vesiglykoliliuos determines its performance characteristics. Higher concentrations of glycol generally lead to lower freezing points and higher boiling points, but can also affect viscosity and heat transfer properties. Ethylene glycol-based solutions are known for their excellent freeze protection but are toxic. Propylene glycol-based solutions are less toxic and are often preferred for applications where accidental ingestion is a concern, such as in food processing equipment or certain types of heating systems.

In addition to antifreeze applications, vesiglykoliliuos can be used as a heat transfer fluid in various industrial processes, HVAC systems, and solar thermal systems. It can also be found in de-icing fluids for aircraft and runways. The choice between ethylene glycol and propylene glycol, as well as the precise concentration, is dictated by the specific requirements of the application, including temperature ranges, safety considerations, and environmental impact.
