Description
Coolant, also known as antifreeze, tank water, etc., is a liquid used in the cooling system of automobiles, engines and other equipment.
Composition:
Coolant usually consists of water, antifreeze and additives. The antifreeze is generally ethylene glycol or propylene glycol, which can lower the freezing point of water and prevent freezing in low temperature environment. Additives include corrosion inhibitors, scale inhibitors, defoamers, etc., which can protect the metal parts of the cooling system from corrosion, prevent scale formation, and eliminate foam in the cooling liquid.
Function:
-Cooling and heat dissipation: Coolant circulates in the engine to absorb the heat generated by the engine, and then dissipates the heat into the air through the radiator, so as to keep the engine in a suitable working temperature range and prevent the engine from overheating.
-Anti-freezing protection: In cold weather, it can reduce the freezing point of water and prevent the water in the cooling system from freezing and expanding, thus preventing the engine block, radiator and other parts from being damaged due to freezing.
-Anti-corrosion and rust prevention: The additives in the cooling liquid can form a protective film on the metal surface, prevent the metal from being corroded by water and air, and prolong the service life of all parts of the cooling system.
-Scale prevention and removal: effectively inhibit the formation of scale in the cooling system, keep the inside of the cooling system clean, and make the cooling liquid play a better role in heat dissipation.
