With the arrival of winter, the sight of heavy snow has brought a lot of inconvenience to people's lives. To ensure road flow and traffic safety, snow melting agents have become an indispensable snow removal tool. Among the many snow melting agents, magnesium chloride is favored because of its high efficiency, environmental protection, economy and other advantages.
1. The principle of magnesium chloride as a snow melting agent.
Magnesium chloride (MgCl2) is a white crystalline or granular solid, and its snowmelt principle is mainly achieved by dissolving and absorbing heat. When magnesium chloride is dissolved in water, it absorbs a lot of heat, making the surrounding environment cooler. At the same time, the ions in the magnesium chloride solution interact with the water molecules in the ice and snow, destroying the structure of the ice crystals, causing the ice and snow to melt rapidly. In addition, magnesium chloride also has the effect of preventing icing, which can effectively extend the snow melting time.
2. Advantages of magnesium chloride as a snow melting agent.
1.High efficiency: Magnesium chloride snow melting agent has a high snow melting efficiency, which can quickly remove snow accumulation in a short time and ensure that the road is clear. Compared with other snow melting agents, magnesium chloride melts snow faster and has a more significant effect.
2.Environmental protection: Magnesium chloride snow melting agent has less pollution to the environment and will not cause serious damage to soil, water sources and plants. At the same time, the residue after magnesium chloride snow melting is environmentally friendly and easy to clean.
3.Economy: As a mineral resource widely present in nature, magnesium chloride is relatively low and has a low cost of use. In addition, the magnesium chloride snow melting agent has a long service life, which can reduce the number of times the snow melting agent is replaced and reduce the cost of use.
4.Safety: Magnesium chloride snow melting agent is safe for human body, animals and plants, and will not cause harm to human health and ecological environment. At the same time, magnesium chloride snow melting agents are less corrosive and do not cause damage to infrastructure such as roads and bridges.
3. Application field of magnesium chloride as snow melting agent.
1.Urban roads: In the snow removal work of urban roads, magnesium chloride snow melting agent can quickly eliminate snow accumulation, ensure the smooth flow of roads, and reduce the occurrence of traffic accidents.
2.Highways: In the snow removal work of highways, magnesium chloride snow melting agent can improve snow removal efficiency, shorten the closure time, and reduce traffic congestion.
3.Airport runway: In the snow removal work of the airport runway, magnesium chloride snow melting agent can ensure the safe take-off and landing of aircraft and improve the operational efficiency of the airport.
4.Railway tracks: In the snow removal work of railway tracks, magnesium chloride snow melting agent can ensure the normal operation of trains and improve the safety and efficiency of railway transportation.
