Antifreeze: engine Antifreeze, which is the media in the engine cooling system in winter, has the functions of cooling, Antifreeze, anticorrosion and antiscaling.
When the engine is working, a lot of heat is generated due to the combustion of fuel and the friction between moving parts. The operating temperature of the engine body is generally 85-95 ℃. If the body temperature is too high, the normal fit clearance is destroyed, causing damage to the bearing and other moving parts, will also reduce the viscosity of the grease, or even oxidation deterioration or burning. So antifreeze as a cooling medium, it is of great significance to keep the cooling system from freezing in cold weather.
The regular brand antifreeze sold on the market is to use ethylene glycol as a material to reduce freezing point, prevent freezing effect, with a low freezing point, not volatile, not flammable, not foaming, at the same time with good liquidity and chemical stability. However, the market is flooded with a large number of fake antifreeze every year, occupy the bottom of the commodity market absolute share. They use methanol, which is more than three or four times cheaper than ethylene glycol, as a material to lower the freezing point and make huge profits. Methanol can effectively reduce the freezing point, but low boiling point, volatile, low flash point and easy to fire. After the use of this kind of antifreeze, as a result of volatile and large loss, to continue to add, and flammable, to the engine fire hazard.
