glükoolsegud

Glükoolsegud, often referred to as glycol mixtures, are solutions where one or more glycols are dissolved in a solvent, typically water. The most common glycols used in these mixtures are ethylene glycol and propylene glycol. These compounds are alcohols containing two hydroxyl groups, which give them unique properties like a low freezing point and a high boiling point when mixed with water.

Ethylene glycol based mixtures are widely utilized as antifreeze in automotive cooling systems. Their primary function is to prevent the engine coolant from freezing in cold temperatures and to raise its boiling point, thus preventing overheating. However, ethylene glycol is toxic and requires careful handling and disposal.

Propylene glycol based mixtures are generally considered less toxic than their ethylene glycol counterparts. This makes them a preferred choice for applications where accidental ingestion or environmental contamination is a concern. Propylene glycol mixtures are also used as antifreeze, but their heat transfer capabilities might be slightly lower than ethylene glycol. They find use in food processing equipment, solar thermal systems, and as de-icing fluids for aircraft.

The specific ratio of glycol to water in a mixture is crucial for determining its freezing and boiling point characteristics. Manufacturers provide guidelines for optimal performance and protection against extreme temperatures. The properties of glükoolsegud can be further modified by adding corrosion inhibitors and other additives to protect the components of the system in which they are used.
