Embodiment Construction

[0011] The deicing agent provided by the embodiment of the present application solves or partially solves the technical problem that the inorganic salt deicing agent corrodes the steel of bridges and road facilities more seriously in the prior art. The snow-melting agent finely combined in different proportions has achieved the technical effect of reducing the corrosion of the snow-melting agent residue on the steel of bridges and road facilities.

[0012] A kind of deicing agent provided by the present invention includes the following components: sodium chloride, sodium hexametaphosphate and water; wherein, sodium chloride and water form a mixed solution; in parts by mass, in every 100 parts of mixed solution, chloride Sodium is 18-22 parts, water is 78-82 parts; the content of sodium hexametaphosphate is: sodium hexametaphosphate per liter of mixed solution is 4 grams; the deicing agent is liquid, which is significantly different from the traditional solid deicing agent ( So...

Abstract

The invention relates to a snow-melting agent. The snow-melting agent is prepared from the following components in parts by mass: sodium chloride, sodium hexametaphosphate and water, wherein the sodium chloride and the water form a mixed solution; counted by mass parts, 100 parts of the mixed solution contains 18 to 22 parts of sodium chloride and 78 to 82 parts of water; the content of the sodiumhexametaphosphate is 4 grams in per liter of the mixed solution and the snow-melting agent is in a liquid state. The snow-melting agent can weaken the corrosion of snow-melting agent residues to steel of bridge and road facilities.

Description

technical field [0001] The invention relates to the technical field of snow-melting agents, in particular to a snow-melting agent. Background technique [0002] At present, in the north, sand and snow plows are still used in winter, and snowmelt is used as a supplement to remove ice and snow on the road to ensure smooth traffic. Deicing agent is an agent that can reduce the melting temperature of ice and snow. The raw materials of ordinary deicing agent are easy to obtain and the price is low. The deicing agent melts the snow on the road by reducing the melting temperature of ice and snow, which is convenient for road dredging. The effect of spreading is obvious, but it is harmful. Research has found that snowmelt residue can corrode road surfaces and car rubber tires. [0003] At present, the deicing agent used in China is mainly sodium chloride (salt, industrial salt), calcium chloride, etc., its low price, and lower freezing point, is a kind of inorganic salt deicing age...
