Feng Shen brand antifreeze advantages function

The full name of antifreeze should be called antifreeze, meaning the antifreeze function of the liquid, antifreeze can prevent cold season parking coolant icing and swelling radiator and freezing engine cylinder block, but we have to correct a misunderstanding, antifreeze is not only used in winter, car normal maintenance projects, every year, need to replace the engine antifreeze, Special vehicle antifreeze replacement frequency should be high.

There are many types of automotive antifreeze, such as calcium chloride (CaCl2) in inorganic substances, methanol (CH3OH) in organic matter, ethanol (C2H5OH, the common name alcohol), ethylene glycol (C2H4 (OH) 2, the common name sweet alcohol), glycerol (C3H5 (OH) 3, Common name glycerin), lubricating oil and sugar, honey, etc., which are common in our daily life, can be used as the mother liquor of antifreeze, after adding an appropriate amount of pure soft water (does not contain or a small amount of water containing calcium and magnesium ions, such as distilled water, unpolluted rainwater, snow, etc., the total hardness of the water component concentration between 0-30ppm), it can become an antifreeze in the general sense.

Because methanol \ ethanol is more volatile, it is not suitable for northern vehicles.

Fengshen brand antifreeze also has the following advantages:

Corrosion protection: The engine and its cooling system are made of metal, including copper, iron, aluminum, steel and solder. These metals in contact with water at high temperatures will be corroded and rust for a long time. The antifreeze not only does not cause corrosion to the engine system, but also has anti-corrosion and rust removal functions.

The boiling point of water is 100 ° C, and the boiling point of antifreeze coolant is usually 110 ° C above zero, so that in summer use, antifreeze is more difficult to boil than water.

Water as a coolant makes the driver headache scale problem, scale attached to the metal surface of the water tank, water jacket, so that the heat dissipation effect is getting worse and worse, and it is difficult to remove. Antifreeze is made of distilled water and added with anti-scale additives, which not only does not produce scale but also has the function of scaling. Of course, if your tank scale is very thick, or first clean with tank cleaning agent and then add antifreeze.

General use: automobile, train diesel locomotive, tractor, ship, engine, water tank and various mechanical equipment, diesel engine, gasoline engine and other cooling systems are used as coolant. It has many functions such as anti-freezing, anti-boiling, anti-corrosion, anti-scale and so on. Like water, it has the advantages of large specific heat, high latent heat of evaporation and convenient supplement. When the ambient temperature is lower than zero, the water in the cooling system will be transformed into ice, and the components of the cooling system will be at risk of expansion and cracking. At this time, the use of antifreeze can ensure that the engine works normally at low temperatures.

With the improvement of engine structure and the progress of material technology, compared with the old engine, a significant feature of the modern automobile engine is the high operating temperature of the modern engine, and the normal operating temperature upper limit is generally more than 100℃. Taking domestic cars as an example, the normal operating temperature of the engine is: Shanghai Santana 90℃ ~ 105℃, FAW Jetta 85℃ ~ 115℃, Fukang 90℃ ~ 118℃. If all water is injected, when the engine temperature reaches 100 ° C, the water will boil "boiling pot", in addition, the water is corrosive, will produce scale to affect the cooling effect. So use a special cooling medium - antifreeze.

Some people think that antifreeze is specially used for vehicles in cold areas, which is a misunderstanding. The main component of antifreeze on the market is ethylene glycol, which has a high boiling point and a low freezing point.

Engine using Fengshen brand antifreeze has the following protective effects:

First, it plays an anti-corrosion protection role for the components of the system.

Second, to prevent scale, to avoid reducing the heat dissipation of the radiator.

3. Ensure that the engine can work within the normal temperature range.

Therefore, the antifreeze of the engine must have the characteristics of antifreeze, anti-pot, anti-corrosion, anti-scale, and no foam, and is not affected by the season and region. Among them, the freezing point and boiling point are the basic indicators of antifreeze.

Use antifreeze must pay attention to the quality. If the quality of antifreeze is poor or even shoddy products, it can not play the role of antifreeze. The coolant is prepared by mixing antifreeze with water in a certain proportion. In the user manual, the automobile manufacturer usually specifies the mixing ratio of antifreeze for different low temperature antifreeze grades, and also specifies the model of antifreeze, which can not be mixed. Under normal circumstances, when the ratio of antifreeze to water is 40:60, the boiling point of the coolant is 106 ° C and the freezing point is -26 ° C, when 50:50, the boiling point of the coolant is 108 ° C and the freezing point is -38 ° C. It is generally required to prepare the coolant at about 5 ° C below the local level. The effective use period of antifreeze is more than two years, and the coolant should be replaced when it expires or is found to be dirty. When replacing, be sure to remove all the old coolant, then add clean water, start the engine to run at idle speed for ten minutes of cycle cleaning. Drain the clean water after shutdown.

Fill the new coolant should be carried out in the cooler, fill the coolant until the liquid storage tank marked "MAXT", screw the lid to start the engine, idle to the normal engine temperature and then turn off the engine, when the body temperature drops, check the liquid level height of the liquid storage tank to maintain the "MAXT" position to pass, otherwise enough to replenish.
