Antifreeze function is the most basic function of antifreeze. In addition, the liquid must have cooling, anti-corrosion and anti-scale and other functions, anti-corrosion is an important technical index to measure the quality of antifreeze. After the use of antifreeze in the cooling system, a protective film with passivation is formed on the surface of the metal parts, which can delay and prevent the further development of corrosion. If the quality of antifreeze is not up to standard, it will accelerate the corrosion of the metal, leading to leakage or corrosion perforation, reducing the service life of cooling system components.
China's state and industry have mandatory technical standards for antifreeze, which requires antifreeze on steel, alloy aluminum, solder, brass, copper, cast iron and other metals have clear standards for corrosion protection. Every year China's quality supervision departments will be on the antifreeze market spot check, will use a variety of media to put the unqualified antifreeze goods public knowledge, but their work is not perfect, a large number of fake antifreeze is still flooded with the market. So, when you purchase antifreeze, be sure to use the regular manufacturers produced antifreeze goods, or your car engine will be fatal injury.
