Description

[0002] In northern China, rain or snow in winter will cause ice on the roads, and road ice and snow disasters cause significant losses to our country every year. In order to resist snow disasters, a large amount of snow melting agents are used, which has caused serious damage to major bridges and roads, resulting in indirect economic losses of 100 billion yuan; in addition, data show that the direct and indirect losses caused by the use of snow melting agents in northern my country are as high as 1 billion yuan each year. There are many types of snow melting agents, mainly chloride salt type and non-chloride salt type. So far, most countries still mainly use chloride salt snow melting agents because of their good effect in melting ice and snow and their low price. Snow melting agents can quickly melt ice and snow, but they will cause serious damage to steel materials such as cars, steel structures, underground pipelines, etc., causing huge economic losses.
