Problems solved by technology

[0002] Snowfall and freezing in winter and spring often bring inconvenience to the city and transportation, and easily lead to traffic accidents, especially highways are often closed due to snowfall and freezing, causing huge economic losses to the society. Clearing road snow has the advantages of low cost, simple method, fast melting speed of ice and snow, and fast traffic recovery, so it has been widely adopted by more and more countries. With the acceleration of China's economic construction, the total mileage of China's expressways ranks first in the world It is in the forefront and is developing rapidly. The "National Expressway Network Planning" pointed out that in the future, 44,000 kilometers of highways will be built in China, and the total mileage of China's expressways and provincial first-class highways will reach 180,000 kilometers. The United States has the largest amount of 90,000 kilometers. However, due to the extremely limited use of deicing agents in China, the economic losses caused by ice and snow are very large every year, especially in recent years. Most of China, especially the southern region, has been hit by four consecutive low-temperature, rain, snow and freezing weather processes, affecting two-thirds of the provinces, municipalities and autonomous regions. The affected population in the country has reached more than 100 million, and the direct economic loss has reached more than 150 billion yuan.
[0003] At present, for the purpose of environmental protection, researchers at home and abroad have developed a variety of non-chlorine salt-type deicing agent products, but they cannot be popularized and used due to cost and technical reasons. Salt-type deicing agents, such as sodium chloride and magnesium chloride, are still the most widely used deicing materials in the United States. In view of this, a new type of deicing agent with chloride salt as the main component has been developed, which can effectively reduce the impact on road infrastructure and ecological environment. Snow melting agent products have important significance and application promotion value

Abstract

The invention discloses an automatic production line of an environment-friendly snow-melting agent and relates to the field of production of chemical raw materials. The environment-friendly snow-melting agent is prepared from the following raw materials in parts by weight: 10 to 20 parts of urea, 8 to 10 parts of magnesium chloride hexahydrate, 15 to 25 parts of calcium carbonate, 10 to 15 parts of sodium metasilicate, 10 to 15 parts of sodium citrate and 5 to 10 parts of a melting accelerating agent. According to the automatic production line of the environment-friendly snow-melting agent, disclosed by the invention, when the atmospheric temperature of high-cold areas is reduced to be -30 DEG C or below, even -45 DEG C, the snow-melting agent can be used for rapidly melting accumulated snow or ice caused by heavy snow and snowstorm, the throwing amount is small and the effect is good; low-temperature frozen disasters caused by extreme climates can be easily defended and eliminated; the environment-friendly snow-melting agent has very good protection effect on dangers caused by traffic roads, bridges, electric power facilities and infrastructures.
