Since this week continued weak domestic ethylene glycol market trading atmosphere, the week has sharply to library support but under the production and adequate supply of new devices in the markets poor mentality, combined with the periphery atmosphere turbulence, Europe and other places outbreak rebound under pressure, led by crude oil products will most weak trend, the market overall supply is adequate, and although the downstream polyester high starts to maintain recently released some device maintenance plan follow-up is expected weaker, long-term supply and demand of surface pattern remains weak, the limited trading days before market operation mentality is weak, the market is expected to range adjustment, Affected by the accident, some market participants are concerned about the operation of the device in the direction of Zhongke.
Applications of ethylene glycol:
1. Freeze protection, heat transfer and hydraulic fluids; Natural gas
And hydrocarbon treating agents;
2. Hydroscopic agents for paper, cork and textile conditioning;
3. Plasticizer formulations and raw materials for ester and

In addition to antifreeze, antifreeze has the following advantages:
Anti-corrosion: The engine and its cooling system are made of metal, copper, iron, aluminum, steel and soldering tin. These metals will corrode and rust over time if they come into contact with water at high temperatures. Antifreeze not only will not cause corrosion to the engine cooling system, but also has anti-corrosion and rust functions.
General use: automobile, train diesel locomotive, tractor, ship, engine, water tank and all kinds of machinery equipment, diesel engine, gasoline engine and other cooling systems used as coolant. With anti - freezing, anti - boiling, anti - corrosion, anti - scale and other functions. The boiling point of water is 100℃, the boiling point of high quality antifreeze coolant is usually 110℃ above zero, so in summer use, antifreeze coolant is more difficult than water to open a pot. The biggest problem for drivers using water as a coolant is scale, which sticks to the metal surfaces of their tanks and water jackets, making cooling less effective and difficult to remove. The high quality antifreeze is made of distilled water and added with anti-scale additive, which not only does not produce scale, but also has the function of descaling. Of course, if your tank scale is very thick, it's best to clean it thoroughly with a tank cleaner before adding antifreeze. Like water, it has the advantages of high specific heat, high latent heat of evaporation and convenient supplement. When the ambient temperature is below zero, the water in the cooling system will turn into ice, and the components of the cooling system will be damaged by expansion cracks. At this time, the selection of antifreeze liquid can ensure the normal operation of the engine at low temperature.
With the improvement of engine structure and the progress of material technology, compared with the old engine, a significant feature of modern automobile engine is that the operating temperature of modern engine is high, and the upper limit of normal operating temperature is generally over 100℃. Taking domestic cars as an example, the normal working temperature of the engine is: 90℃ ~ 105℃ for Shanghai Santana, 85℃ ~ 115℃ for FAW Jetta and 90℃ ~ 118℃ for Fukang. If all the water is injected, it will boil over when the engine temperature reaches 100℃. In addition, the water is corrosive, which will produce scale and affect the cooling effect. So, a special cooling medium, antifreeze, is used.
It is a misconception that antifreeze is used exclusively for vehicles in cold regions. The antifreeze liquid on the market is mainly composed of glycol, which has the characteristics of high boiling point and low freezing point. The antifreeze liquid also contains additives to prevent the oxidation of ethylene glycol (will form a corrosive byproduct), prevent corrosion, prevent foam, etc.
Protection function: 1. Protect the components of the cooling system against corrosion. Two, prevent scale, avoid reducing the heat dissipation of the radiator. Three, ensure that the engine can work within the normal temperature range.
Therefore, the engine antifreeze, must have anti-freeze, anti-calking, anti-corrosion, anti-scale, no foam characteristics, not affected by the season and the region. Among them, freezing point and boiling point are the basic indexes of antifreeze fluid.
