Snow melt agent is a chemical that can reduce the melting temperature of snow and ice. The raw materials of common snow melting agent are easy to obtain and low in price, and its components are mainly potassium acetate and chlorine salt, and are classified by these two kinds. Snow melting agent melts snow on the road by reducing the melting temperature of snow and ice, which is convenient for road dredging, and the effect of sowing is obvious, but it is harmful. Research has found that the residue of snow melting agent can corrode the road surface and automobile rubber tires. In the north, sand and snow plows are still used mainly in winter, and snow melting agents are used as auxiliary ways to clear snow and ice on the road to ensure smooth traffic.
