Environment-friendly snow melt agent

Abstract

The invention relates to an environment-friendly snow melt agent. The snow melt agent uses anhydrous calcium chloride as a main component, contains various additives such as sodium citrate, sodium dihydrogen phosphate or disodium hydrogen phosphate, sodium metasilicate and urea, and also contains abscisic acid or indolylacetic acid or a mixture thereof, sodium tartrate, humic acid and salt thereof. The snow melt agent can effectively reduce corrosivity to metal objects and concrete structures, and effectively improve salinization resistance of seeds, plants and soil. The snow melt agent can quickly melt accumulated snow or ice due to snowstorms when temperature drops to minus 25 DEG C or even minus 50 DEG C in serious cold areas with a small amount and good effect. The invention further provides a use method of the snow melt agent. In the method, the main component and various additives are kept separately without preparing a finished snow melt agent in advance, and combined on site before use. The method can help prevent the problems of dampness, hardening and the like during storage and transport of the finished snow melt agent, and the defects of high temperature energy consumption and possible additive decomposition during the preparation of compound granules (for example, coating and pelleting). The snow melt agent has the advantages of simple operation and low cost, and is especially applicable to field mechanical throwing operation.

Description

Technical field [0001] The invention relates to an environment-friendly snow melting agent with anhydrous calcium chloride as the main component, and contains multiple additives. Background technique [0002] Snowfall and icing in winter and spring often bring inconvenience to cities and transportation, and can easily cause traffic accidents. In particular, expressways are often closed due to snowfall and freezing, causing huge economic losses to society. The use of snow-melting agents to clear road snow has the advantages of low cost, simple method, fast ice and snow melting speed, and fast traffic recovery, and is widely used in more and more countries. With the acceleration of my country’s economic construction, my country’s total highway mileage ranks among the top in the world, and is showing a rapid development momentum. The National Expressway Network Plan pointed out that in the future, my country’s highways will be 44,000 kilometers to be built. The total mileage of firs...

Problems solved by technology

[0004] 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
