Objective winter is cold and dry, and more, in order to guarantee the smooth roads, railways, airports and other, you need to use snow melt (ice) makes the rapid melting of snow, snow played the role of antifreeze. The common melting snow (ice) is a snow-melting chloride (ice) agents, but chloride ion corrosion damage, such as roads, railways and other reinforced concrete. At present, both at home and abroad have started to study on chlorine-free environmentally-friendly snow-melting (ice) agent (CMA). This paper reviews the snowmelt (ice) the classification, specification, introduced environmentally-friendly snow-melting (ice) preparation of principle, focuses on CMA's application research progress and existing bottlenecks.

A, and thaw snow (ice) agent of classification, and technology index thaw snow (ice) agent main is divided into three big class: first class for chlorine salt type, main has Na Cl, and Ca Cl2, and Mg Cl2, and KCl, type, which most common of is industrial salt Na Cl; second class for non-chlorine type, main has inorganic salts, and acetic acid potassium, and amine, and alcohol,, which most common of is acetate calcium magnesium salt; third class for mixed type thaw snow agent, main has chlorine salt and non-chlorine salt of mixed, and chlorine salt and non-chlorine salt added resistance rust agent of mixed [1]. Evaluation of melting snow (ice) agent specification has many of the qualities, from melting snow (ice) properties, corrosion resistance and heavy metal content and other factors to consider.
