Abstract

The invention discloses a snow-melting agent, which contains a large amount of acetate and nitrate and a certain content of cosolvent while containing chloride. On one hand, the snow-melting agent ensures the snow-melting effect, and simultaneously, acetate and nitrate do not corrode roads, so that the corrosion damage of chloride ions to the road structure is reduced, and the service life of the roads is prolonged; on the other hand, after the snow-melting agent permeates the land on both sides of the road, the nitrogen fertilizer brought by the nitrate also promotes the growth of plants. In addition, the snow-melting agent disclosed by the invention also comprises very fine organic fertilizer particles, and after the snow-melting agent permeates into the soil on the two sides of the road, the organic fertilizer particles reduce the content of soil salinity and avoid the occurrence of soil hardening.

Description

Snow-melting agent
Technical Field
The invention relates to the technical field of snow melting, in particular to a snow melting agent.
Background
The condition of the road surface is an important factor influencing the safety of the road, and in cold winter, when the road surface is snowy or iced, the adhesive force of the road surface is greatly reduced, which is extremely bad for the safety of pedestrians and vehicles, so that the problem of snow melting and ice melting of the road surface in winter cannot be ignored.
The current snow and ice melting methods mainly comprise 5 methods: snow removal by manpower and machinery, snow removal by a snow-melting agent, snow melting by external heating, self-stress snow removal and the like. The large-scale application of external heating and self-stress snow removal cannot be realized due to the reasons of large investment, high energy consumption, high maintenance cost and the like, and the manual and mechanical snow removal has limited effect in snow melting and ice melting in winter due to the reasons of low efficiency and the like. Therefore, snow removal by the snow-melting agent is a main method for simply, quickly and low-cost snow and ice melting in winter.
At present, sodium chloride, calcium chloride, magnesium chloride and other raw materials are used as main snow melting agents in China due to low price and easy availability. However, the conventional snow-melting agent not only corrodes and destroys road structures to greatly reduce the life thereof, but also alkalinizes salts thereof after permeating into the soil on both sides of the road to affect plant growth.
