Abstract

The present invention relates to a new effective corrosion-free snow-removing agent, it is made up by using by-product produced in the propcess of deep-processing corn with one or several chlorides. Said snow-removing agent is high in efficiency, low in cost, non-toxic and harmless and corrosion-free.

Description

A kind of environment protection snow removing agent

The present invention relates to the high-level efficiency low-corrosive ice and snow eliminating agent, it is made up of soak solution in the corn deep processing process and muriate, and wherein the weight concentration of the soluble substance of corn steep liquor can be distributed in the scope of 1%-14%.The present invention can be used to eliminate highway, bridge, and the street, the square, the ice and snow at airport or other open-air ground and buildings place or before snowfall, be sprayed on highway, bridge, the street, the square, airport or other open-air ground or buildings freeze in ground to prevent accumulated snow.

At present the northern China snow-melting agent that institute generally uses winter is sodium-chlor and other muriate.But it is exactly that corrodibility is very strong that the muriate snow-melting agent all has a fatal weakness, can be to cement works, and bituminous pavement and vehicle cause serious harm.The widely accepted Snow Agent of a kind of energy should have following characteristic: 1, stronger snow melt ability and lower chill point are arranged; 2, environmental pollution is very little; 3, harmless to the ground and the vehicles; 4, Financial cost has competitiveness; 5, ample supply and prompt delivery; 6, soluble in water and can be existing tool and method and use.

The invention provides does not a kind ofly have visible pollution to environment, does not have corrosion, and snow melt is effective, and aboundresources is with low cost, wieldy antifreezeization ice and snow melting agent and anticorrosive agent.

Raw material involved in the present invention is the byproduct-corn steep liquor in the corn deep processing process.In wet method corn deep processing process, the first step is that corn is soaked, remove after the immersion corn remaining liquid be corn steep liquor.General corn steep liquor contains dry 6%-10%.The main component of dry is crude protein and ash content.Typical component is characterized as: dry powder contains crude protein 33%.This soak solution dry is the low-nutrition feed additive.Corn steep liquor mixed with muriate not only reduce muriatic corrodibility greatly, also reduce its freezing point greatly.Be antifreezeization of ideal ice and snow melting agent, can easily be sprayed on the ground of required anti-ice and snow with existing tool equipment.Also can use in the back of heating.This nothing corrosionization ice and snow melting agent can be sprayed on road surface or other body surface before snowfall, it can be attached to this surface and resemble for a long time and not and be easy to be taken away by wind or vehicle the salt.If use modern spraying vehicle, the people of use does not need special training, the speed of a motor vehicle or speed of a motor vehicle sprinkling faster that can 60 kilometers/hour.The sprinkling amount is every kilometer runway 45-140 liter, or is equivalent to every square metre of 15-45 milliliter.

By corrosive experimental result of the present invention is shown: the circular hole that to have a diameter in the middle of the steel disc of 50 * a 25 * 2mm be 7mm is placed soak water of maize and magnesium chloride mixed solution, and (wherein soak solution dry weight concentration is 4%, density of magnesium chloride is 24%) in 15 days, loss amount is 3.2 milligrams.Corrodibility is lower than pure water.To cement, bituminous pavement does not have corrosion phenomenon, and asphalt surface is not seen obscission.Freezing point is subzero 47 degree Celsius.

The experiment of snow melt ability shows: compare with common snow-melting agent sodium chloride aqueous solution (23%), externally temperature is under-10 ℃ of conditions, the snow melt ability of above-mentioned soak water of maize and magnesium chloride mixed solution (wherein soak solution dry weight concentration is 4%, and density of magnesium chloride is 24%) is more than the twice of salts solution.Still have the snow melt ability and salts solution loses the snow melt ability when subzero 20 spend at 40 degrees below zero.

Use of the present invention not only can help to solve anti-icing snow melt problem in north winter, can also help corn producing industry, for its byproduct finds new market.
