Is the coolant antifreeze?

Coolant is antifreeze, these two names are actually abbreviations, the full name should be called antifreeze coolant.Antifreeze coolant is a coolant containing special additives. The main component of most antifreeze is ethylene glycol, because ethylene glycol has a high boiling point and a low freezing point.Automobile antifreeze is mainly used in the cooling system of liquid-cooled engines, and has excellent properties such as antifreeze in winter, anti-boiling in summer, anti-scale and anti-corrosion. The specific functions of automobile antifreeze are as follows:

1cooling effect

During the use of the car, the engine is in a high temperature operation state. If the car engine has been working at high temperature, the engine will be damaged or even paralyzed in a short time. Antifreeze is added to the cooling system, the heat of the engine will pass through the cooling system, and the heat will be reduced and then dissipated to the surrounding, which has a cooling effect and avoids boiling.

2,Antifreeze

In winter, when the temperature is low, the engine and cooling system are easy to freeze, causing the car to fail to start. In order to enable the car to continue to be used in low temperature in winter, some antifreeze is added to the antifreeze of the car. Generally, the freezing point can reach minus 40 ℃, and the better can reach minus 60 ℃, which can keep the cooling system from freezing in low temperature weather. Antifreeze effect.

3anti-corrosion effect

Most of the automotive cooling system components are made of metal. Due to the different electrode potentials of different metals, electrochemical corrosion is prone to occur under the action of the electrolyte. A certain amount of anti-corrosion additives are added to the automotive antifreeze and added to the refrigeration system to prevent the cooling system from generating Corrosion, play a role in anti-corrosion.

4anti-scaling effect

The water contains a large amount of anions and cations. When added to the automobile cooling system, the cations in the water will react with other anions to form scale during use. In the production and filling process of automobile antifreeze, deionized water that has been softened is used. So it has anti-scaling effect.
