Problems solved by technology

[0002] As we all know: ice and snow on the road surface in cold areas in winter brings great safety hazards to traffic and people's travel. Mechanical snow removal can alleviate some traffic problems, but it can't do anything to the ice surface. For a long time, chlorine salts have been used to remove ice and snow, causing damage to the road surface. Bridges, vegetation and other hazards, environmental protection deicing agents have emerged in recent years, but there are many types and very miscellaneous, most of them still add a small amount of anti-corrosion agent to chlorine salt, and there is no real economical and effective road deicing agent
Chinese patent ZL02109118.8 provides a liquid deicing agent. Because it is in a liquid state, there are many inconveniences in storage and transportation, which affects its popularization and use.

Embodiment 1

[0012] Take 30 kg of corn starch processing by-products, which contain 80% protein, 3% phytic acid, 5% maltose, 17% minerals and 5% vitamins, crush it, pre-wet with 900 ml of water, add 30 kg Nacl, 10 kg of ammonium phosphate, and 10 kg of sodium acetate are crushed, stirred, granulated, and dried to make deicing agent.

Embodiment 2

[0014] Take 15 kg of corn starch processing by-products, which contain 70% protein, 5% phytic acid, 5% maltose, 15% minerals and 5% vitamins, pre-wet with 600 ml of water after crushing, add 40 kg of CaCl 2 and 15 kilograms of magnesium acetate pulverized into fine powder, stirred evenly, granulated, and dried to make deicing agent.

Embodiment 3

[0016] Take 60 kg of by-products of corn deep processing, which are produced by the deep processing of corn starch, which contains 75% protein, 3% phytic acid, 4% maltose, 14% minerals and 4% vitamins, crushed and pre-wetted with 1400 ml Finally, add 20 kg of urea and 50 kg of sodium phosphate. Crush fine powder, stir, granulate, and dry to make deicing agent.

Abstract

The environment friendly granular road snow removing agent consists of side product from corn starch production process in 14-80 weight portions, inorganic matter in 15-64 weight portions and organic acid salt in 5-22 weight portions, and through separating grinding into fine powder, mixing via stirring, pelletizing and drying. The environment friendly granular road snow removing agent is spread to icy and snowy road to avoid slide, thaw ice and snow and loosen ice and snow, and has no corrosion to road, no environmental pollution, simple production process and low cost. It may be used widely for eliminating ice and snow in cold area.

Description

technical field [0001] The invention is an improvement to the existing liquid road deicing agent, discloses an environment-friendly road granular deicing agent, which belongs to the technical field of road surface ice and snow treatment.
