Our commonly used snow melting agent is mainly sodium chloride, calcium chloride, magnesium chloride and other chloride salts as the main component of inorganic snow melting agent, chlorine salt melting agent dissolved in snow, freezing point will fall below zero, the freezing point of salt water is lower than the freezing point of water, so it is difficult to form ice cubes after the salt dissolved in snow. After the melting agent is dissolved in water, the concentration of ions in the water rises, so that the liquid vapor pressure of the water drops, but the solid pressure of the ice is unchanged. In order to reach the state where the solid and liquid vapor pressure of the ice water mixture is equal, the ice melts.

Snow melt agent, is used to reduce the melting temperature of snow and ice melt snow products on the road, snow melt agent solid snow melt agent, liquid snow melt agent, with inorganic matter and inorganic matter mixed with organic snow melt agent. A common snowmelt agent is potassium acetate as the main component of organic snowmelt agent, as well as "chlorine salt" as the main component of inorganic snowmelt agent, than sodium chloride, calcium chloride, magnesium chloride, etc., commonly known as "ice salt".

Snowmelt agent, mainly used as urban roads, airports, ports, Bridges and other facilities of snow melting ice, but also in winter construction speed melting agent and antifreeze admixture.
