Car owners want their "iron horse" to serve for decades. Therefore, many listen to the sound of the engine, try to refuel at proven gas stations, buy high-quality oils, as well as antifreeze. However, for a novice motorist, choosing the right tools to improve car performance is a long journey of trial and error. So, one of the problems is the choice between antifreeze and antifreeze, because for uninitiated people, these two coolants are no different. It is worth finding out if they are so similar in reality.
Instructions
Step 1
Antifreeze refers to all coolants, regardless of when and where they are released. Antifreeze is a type of antifreeze, which was created in Soviet times by the Institute "GosNIIOKHT". Since there was no alternative to this type of coolant, the brand name soon became a household name. For a long time, other antifreezes were also called that, which came to the Soviet and then the Russian market. TOSOL is an abbreviation. The first 3 letters stand for "organic synthesis technology". As for the ending ol, it comes from chemical terminology.
Step 2
In the composition of antifreeze, as in other coolants, there is water and ethylene glycol. In antifreeze, additives are used based on salts of inorganic acids, for example, silicates, phosphates, nitrites and nitrates. The antifreeze also contains water and ethylene glycol, propylene glycol, glycerin and alcohol. In other words, antifreeze is propylene glycol (or ethylene glycol), additives, and water. It is the additives that are especially important in the composition, since they increase the anti-cavitation, anti-foam, anti-corrosion capabilities of the antifreeze. Unlike antifreeze, this coolant contains additives based on organic acid salts.
Step 3
Thanks to antifreeze, a protective layer is formed on the surface of metals. Usually its thickness does not exceed 0.5 mm, but such protection has a drawback - low heat transfer. Because of this, fuel consumption increases, and the engine itself wears out faster. Antifreeze loses its cooling capacity after 30-40 thousand kilometers. Since antifreeze contains inorganic salts such as silicates and phosphates, deposits and gels can form, which can cause radiator clogging. At high temperatures, antifreeze functions in the system up to a limit of 105 ° C.
Step 4
Antifreeze, in turn, forms a protective layer only on corroded walls. Since there is no protective layer on the rest of the metal, the heat transfer remains intact. Such a coolant does not lose its properties when a passenger car has driven more than 250 thousand kilometers. Since organic salts are used in carboxylate fluids, no precipitation is formed. Antifreeze is capable of boiling at a temperature of 115 ° C.
Step 5
Thus, the following differences between antifreeze and antifreeze can be identified:
- antifreeze is a brand of antifreeze developed in the USSR, antifreeze is a general name for any coolant;
- additives in the composition of antifreeze - organic salts, and in the composition of antifreeze - inorganic;
- antifreeze forms a protective layer only in places of metal corrosion;
- antifreeze forms a protective layer of 0.5 mm, while impairing heat transfer;
- antifreeze loses its cooling capacity after 250 thousand kilometers, and antifreeze - after 30-40;
- antifreeze boils at a temperature of 115 °, and antifreeze is less resistant to high temperatures.
Now you know how antifreeze is fundamentally different from antifreeze.
