Low winter temperatures, in order to make the car continue to be used in low temperatures in winter, the engine coolant has added some can reduce the freezing point of water as antifreeze, keep the cooling system does not freeze in cold weather. So people sometimes refer to coolant as "antifreeze" or "antifreeze." The full name of antifreeze should be called antifreeze coolant, meaning antifreeze function coolant. Chinese name car antifreeze, the English name Automotive antifreeze, another name antifreeze,

 

       Definition: Coolant, also known as antifreeze, is a liquid consisting of antifreeze additives and additives to prevent corrosion of metals and water. It needs antifreeze, corrosion resistance, thermal conductivity and non-deterioration properties. Glycol is now often used as the main ingredient, plus anti-corrosion add water and antifreeze.

 

       The internal combustion engine's engine cooling system is a liquid-cooled closed cycle system consisting of a cylinder, a jacket and a water tank. The working status of the cooling system directly affects the normal operation of the vehicle and the service life of the vehicle. Antifreeze is the internal combustion engine cooling system cooling medium, mainly by the antifreeze, corrosion inhibitors, defoamers, coloring agents, antifungal agents, buffers and other components. With the development of automobile industry, the engine performance requirements are also higher and higher, not only requires antifreeze has a lower freezing point and higher boiling point, but also should have good metal corrosion resistance, anti-cavitation, anti-knot Fouling, and little or no pollution to the environment, and has a long service life and so on the comprehensive performance. Countries have done a lot of research on this, continue to introduce formula patents and excellent antifreeze products. In some advanced countries, the penetration rate of antifreeze reaches 100%. The penetration of domestic antifreeze is low, a considerable amount of commercially available antifreeze is imported, due to higher prices, generally used for imported vehicles. Although the production of domestic antifreeze increased rapidly in recent years, many products lack of strict quality inspection and uniform inspection standards. To this end, we must absorb advanced foreign technology and China's actual situation, development and production of multi-functional high-efficiency antifreeze to meet the growing market demand.

 

       The role of antifreeze: antifreeze and antifreeze The full name of antifreeze coolant, from the name you can see it has two main functions: The first is antifreeze, the second is cooling. Antifreeze prevents the vehicle from freezing the cooling system of the vehicle while the vehicle is frozen in the cold winter and prevents "boiling off" in the summer. In addition, antifreeze in addition to "antifreeze", there is a feature is the boiling point high. We all know that the boiling point of water is 100 ℃, while the antifreeze boiling point is generally 110-120 ℃, which protects the engine to prevent the "open pot" has a significant role.
