How many types of antifreeze are there?
1 Answers
Common types of antifreeze include ethanol-based, calcium chloride-based, and methanol-based. Each has distinct characteristics: Ethanol-based antifreeze is a colorless, slightly viscous liquid with a boiling point of 197.4°C and a freezing point of -11.5°C, capable of mixing with water in any proportion. Calcium chloride-based antifreeze has a boiling point of 1600°C, is highly soluble in water, and releases heat during dissolution. Methanol-based antifreeze has a boiling point of 64°C and can fully mix with water. Functions of antifreeze: Prevents freezing: Prevents freezing when the vehicle is not running, as antifreeze resides in the engine block where liquid-to-solid expansion could crack it. Cools the engine: Cools the engine after vehicle startup to prevent overheating and potential damage. Prevents rust and excessive scale buildup: Which could lead to pipe blockages.
