Introduction to automotive antifreeze

Antifreeze, also known as coolant and antifreeze, is a liquid composed of antifreeze additives and additives to prevent corrosion of metals and water. It requires antifreeze, corrosion resistance, thermal conductivity and deteriorating properties.

The engine cooling system of an internal combustion vehicle is a liquid-cooled closed circulation system consisting of a cylinder, a jacket and a water tank. The working state of the cooling system directly affects the normal operation of the vehicle and the service life of the vehicle. Antifreeze is the cooling medium of the circulating cooling system of internal combustion engine. It is mainly composed of antifreeze, corrosion inhibitor, defoamer, colorant, antifungal agent and buffer. With the development of the automotive industry, the performance requirements of the engine are also getting higher and higher, not only the antifreeze has a lower freezing point and a higher boiling point, but also has better metal corrosion resistance, cavitation prevention, and anti-knot. Scalability, as well as comprehensive performance in terms of little or no environmental pollution, and long service life.

Countries have done a lot of research on this, and continue to introduce formula patents and excellent antifreeze products. Antifreeze penetration rates in some advanced countries have reached 100%. The penetration rate of domestic antifreeze is low. A considerable amount of commercially available antifreeze is imported. Because of the high price, it is generally used for importing vehicles. Although the production of domestic antifreeze has grown rapidly in recent years, many products lack strict quality inspection and uniform inspection standards. To this end, we must absorb foreign advanced technology and combine the reality of China to develop and produce multi-functional high-efficiency antifreeze to meet the growing market demand.
