Embodiment 1

[0012] Embodiment 1, a kind of preparation method of environment-friendly coated deicing agent, is characterized in that: comprises the following steps successively:

[0013] (1) Mixing: get the industrial salt with a water content of 4%-6%, mix the corrosion inhibitor sodium citrate which is 2%-3% of industrial salt by weight into the industrial salt, and mix the two evenly ;

[0014] (2) Pulverization: Send the mixed industrial salt and sodium citrate into the pulverizer by the belt conveyor, pulverize to a particle size of 5mm, and the sodium citrate evenly adheres to the pulverized industrial surface of salt particles;

[0015] (3) Drying: The industrial salt particles adhered to sodium citrate are fed into the vulcanized bed by a belt conveyor, and jump, roll and move forward under the blowing of high-temperature and high-pressure air with a temperature above 280°C. After drying, they form coated granules;

[0016] (4) Cooling: cooling the coated granules to room tempe...

Abstract

The invention discloses an environment-friendly coated snow-melting agent. When the environment-friendly coated snow-melting agent is used, sodium citrate on the surface is melted by absorbing moisture of snow, permeates into a road and a bridge and is attached to the surfaces of steel bars of the road and the bridge, so that the surfaces of steel bars of the road and the bridge can be prevented from being corroded by salt water, a function of protecting the road and the bridge is realized, the environment cannot be influenced, and good economic, environment-friendly and snow-melting effects are achieved.

Description

technical field [0001] The invention relates to a preparation method of a deicing agent, in particular to a preparation method of an environment-friendly coated deicing agent. Background technique [0002] In winter in cold regions, snowfall causes snow and ice to accumulate on the road surface, making it difficult for vehicles to pass. In order to melt the ice and snow on roads, bridges, streets, squares, airports or other open grounds, and eliminate the adverse effects of snow on roads on transportation and people's lives, Deicing agents are usually used. Among many deicing agents, inorganic salt deicing agents including sodium chloride, magnesium chloride or calcium chloride are widely used because of their fast melting of snow and ice, and economical applicability. Metal objects such as steel bars in the concrete of the bridge are corrosive. Contents of the invention [0003] The object of the present invention is to aim at the deficiencies of the prior art, and prov...
