What is car antifreeze for? What is car antifreeze used for

The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze prevents coolant from freezing and cracking radiators and freezing engine blocks or covers when the coolant freezes when parking in the cold winter. Many people think that antifreeze is only used in winter, but in fact, antifreeze is used all year round.

General use: automobiles, trains, diesel locomotives, tractors, ships, engines, water tanks and various mechanical equipment, diesel engines, gasoline engines and other cooling systems are used as coolants. It has a variety of functions such as anti-freezing, anti-boiling, anti-corrosion, and waterproof.

The boiling point of water is 100, and the boiling point of high-quality antifreeze coolant is usually 110 above zero, so that in the summer, antifreeze coolant is more difficult to boil than water. The biggest headache for drivers with water as coolant is the problem of scale, which adheres to the metal surface of the water tank and water jacket, making the heat dissipation effect worse and worse, and it is also difficult to remove. The high-quality antifreeze is made of distilled water and added with anti-scale additives, which not only does not produce limescale but also has the function of descaling.

Of course, if your tank is very thick with limescale, it is best to thoroughly wash it with tank cleaner before adding antifreeze.

Prevents coolant from freezing and cracking radiators and freezing engine blocks or covers when the coolant is shut down in the cold winter. Its main indicator is the freezing point of the antifreeze. When selecting or formulating the antifreeze, its freezing point should be about 10 below the minimum temperature in the region to ensure that the antifreeze does not freeze in exceptional circumstances.

Another important function of antifreeze. Its main indicator is the boiling point. The boiling point refers to the condition that the coolant begins to heat up to the control temperature of boiling under the condition that the cooling system of the automobile engine is in equilibrium with the outside atmospheric pressure, and the engine is kept working at normal temperature.

Antifreeze also provides protection against corrosion. Corrosion is a remote process in which metals are destroyed in the natural environment due to chemical reactions, electrochemical processes, and physical uses. At present, there are six kinds of metals that are mainly anti-corrosion, namely:

Steel, cast iron, copper, solder, brass, cast aluminum. Most of the cooling systems of modern automobile engines are made of cast aluminum and aluminum alloy parts, so the focus of antifreeze corrosion protection should also be shifted to anti-corrosion of aluminum, and the dissolution, bulging and aging of non-metallic materials such as rubber and plastics in the cooling system should also be considered. Corrosion inhibitors are substances that stop or slow down these processes.

Another important function of antifreeze is waterproofing, which is caused by the attachment of insoluble salts or oxide crystals to the surface of the radiator. After the scale is generated, it not only affects the normal heat dissipation of the radiator, but also is more likely to cause the blockage of the circulation pipe of the cooling system, and the water temperature is too high and seriously affects the normal operation of the engine. The main substances that can produce limescale in the cooling system:

Calcium sulfate, calcium carbonate, magnesium carbonate, etc., as well as brown calcium phosphate produced by improper use, etc. Calcium and magnesium ions are mainly used in the water in the coolant, so the water quality of the cooling antifreeze must be strictly controlled. According to the structural characteristics of the engine, the manufacturer has made strict requirements for the use of coolant for the engine, and has clear requirements for the general use of long-term antifreeze and antirust liquid.

Hello, dear <>

The function of automotive antifreeze is: to provide antifreeze protection for the engine and resist the low temperature environment; Prevent the coolant from icing and cracking the radiator when stopping in the cold winter, freezing the engine block and cylinder head; Provides efficient heat dissipation. Automobile antifreeze, also known as antifreeze, in order to make the car continue to be used in low temperatures in winter, the engine coolant will add some substances that can reduce the freezing point of water as antifreeze to keep the cooling system from freezing in low temperature weather.

The components of automotive antifreeze are: calcium chloride in inorganic matter, methanol, ethanol, ethylene glycol, glycerin, glycerol, lubricating oil and purified water in organic matter.

Automotive antifreeze is a liquid used to prevent and provide cooling for automotive cooling systems that freeze in the wild at low temperatures. It is usually made from a mixture of various organic compounds such as ethylene glycol, propylene glycol, butyl acetate, ethanol, etc.

The main functions of automotive antifreeze are as follows:

1.Prevents coolant from freezing at very low temperatures and prevents damage to cooling systems such as engines and radiators.

2.Provides cooling to keep the engine operating temperature within the appropriate range.

3.Prevents corrosion and prolongs the longevity of the cooling system.

4.Raise the boiling point to prevent the car from overheating in a high-temperature environment.

Therefore, automotive antifreeze is an indispensable liquid for maintaining the normal operation of automobiles.

It is often said that the car should change the antifreeze on time, and not changing the antifreeze on time will lead to some consequences of use. So what is the shack hand is car antifreeze? How often do you change antifreeze in your car? What are the consequences of not changing antifreeze for five years? Let's take a look!

1. What is automotive antifreeze?

The full name of antifreeze is antifreeze coolant. It plays three roles to prevent the vehicle from freezing when it is not started, because the antifreeze is in the cylinder, and the volume will expand when the liquid becomes solid, so it will freeze and crack the cylinder. Another feature is to cool the engine after the vehicle is started.

Prevent engine damage due to excessive temperature. Crude antifreeze also plays a role in managing rust and preventing pipes from clogging due to excessive limescale. 2. How often do you change your car antifreeze?

Antifreeze is usually replaced every 2 years, about 6w km.

What are the consequences of not changing antifreeze for three or five years?

If the antifreeze is not replaced for 5 years, the water in the antifreeze will evaporate, causing the freezing point of the antifreeze to change, which will affect the effect. Antifreeze has the functions of rock and erosion, anti-corrosion, rust removal and so on. The long-term operation of the engine causes a certain consumption of additive components, and after reaching a certain level, it cannot play the role of anti-corrosion, anti-corrosion and rust removal on the engine, which affects the service life of the engine.

The above is what car antifreeze is, and what will happen if you don't replace it for 5 years. Hope it helps!

Antifreeze, also known as antifreeze coolant, is a type of coolant that contains special additives. 1.Its main function is to bring good heat dissipation to the car engine, anti-boiling in summer, and anti-freezing in winter.

Antifreeze is used not only in winter, but all year round. 2.Automotive antifreeze is a type of coolant containing special additives that is mainly used in the cooling system of liquid-cooled engines.

Antifreeze has the effect of anti-freezing in winter and anti-boiling in summer. It can be water-resistant all year round. There are many types of antifreeze for motor vehicles, and you can choose the right type of antifreeze according to your specific model.

3.It not only has the functions of "anti-freeze" and "cooling", but also has the functions of anti-corrosion and rust removal for all parts of the cooling system.

Antifreeze is mainly used in the cooling system of liquid-cooled engines, and antifreeze has the functions of antifreeze in winter, boiling in summer, waterproof and anti-scale and anti-corrosion throughout the year to ensure that the engine can work within the normal temperature range.

During the use of the car, the engine is in a high-temperature running state, if the car engine has been working at high temperature, it will cause engine damage or even paralysis in a short time. When the antifreeze is added to the cooling system, the heat of the engine will pass through the cooling system, and the heat will be dissipated to the surrounding area after the heat is reduced, which will play a cooling role and avoid boiling.
