At present, China has developed more types of deicing salt, divided by the solid and liquid states of matter; divided according to the composition of inorganic and organic compounds and inorganic materials mixed with a mixture of inorganic and organic compounds is the most environmentally friendly deicing salt which more or less for free mixture of chlorine and other chemicals MgCl2-; also classified according to different purposes, generally used for lower quality urban roads, bridges for the high quality requirements of the airport and other places, but its quality is must meet the standards. In addition to environmentally friendly deicing salt (the role of co-solvents, etc.) as a key technology component ratio, the additives are also confidential data currently rely on domestic production and sales of calcium chloride deicing yields a rough calculation. Domestic annual output of about 1 million tons of deicing salt, 1/3 export volume.

        There are two main deicing salt, deicing salts of organic deicing salt and chlorine. Organic deicing no corrosive effect on infrastructure, because the price is too high, but at the airport, golf courses and other places a small amount of application; in the city, the highway is used widely in snowmelt chlorine deicing salts.

        Deicing salt types: one is based on potassium acetate as the main component of organic deicing salt, deicing snowmelt such good effect, basically no corrosion damage, but its price is too high, generally used for airports and other important places. Another is based on "chloride" as the main ingredient of inorganic deicing salt, such as sodium chloride, calcium chloride, magnesium chloride, potassium chloride, etc., is commonly known as 'deicing salt'. The advantage is cheap, only about 1/10 of organic deicing salt, but its large-scale erosion of public infrastructure is very serious. Our common deicing was part of this, the most used is sodium chloride (ie, industrial salt).
