It is formed with 30%~40% ammonium acetate.
It is highly preferred that by mass percentage, the deicing salt by 30% potassium acetate, 30%~32% sodium acetate and
38%~40% ammonium acetate composition.
The preparation method of above-mentioned deicing salt, comprising:
Potassium acetate, sodium acetate and ammonium acetate are separately dried, crushed；
Then, amount weighs potassium acetate, sodium acetate and ammonium acetate according to the ratio, is uniformly mixed, and through drying, crushes, and obtains described
Deicing salt.
The application method of above-mentioned deicing salt, comprising: the deicing salt is dissolved with water, then sprays snow melt.
Preferably, concentration is 10%~30% by mass percentage, and the deicing salt is dissolved with water.
It is highly preferred that concentration is 20% by mass percentage, the deicing salt is dissolved with water.
Beneficial effect
Compared with existing deicing salt, deicing salt of the invention has stronger ice melting capability, and corrosivity is small, at low cost,
It is small on plant growth influence, it is a kind of deicing salt for being mainly used for road deicing snow melt of environmental protection and economy.
Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings:
Fig. 1 is ice melting capability of the deicing salt of the present invention at -10 DEG C；
Fig. 2 is the test result of deicing salt corrosion of carbon steel of the present invention；
Fig. 3 is influence of the deicing salt of the present invention to soya bean seed development.
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Embodiment 1
The regression equation of ice storage Yu each group distribution ratio is established using Simplex-barycenter design method, specific as follows:
The raw material such as potassium acetate, sodium acetate, ammonium acetate are dried first, are ground when its constant temperature quality is unchanged
It is broken, it is ground to powdered；
Then above-mentioned three kinds of raw material are weighed respectively by the proportional quantity of Simplex-barycenter design table (as shown in table 1), place
In that it can be sufficiently stirred in stirring container, it is uniformly mixed it；
The mixture stirred evenly is dried again finally, pulverized, be ground to again after being dried to it
It is powdered；
Said mixture is configured to liquid spray-type snow melt agent solution by 20wt% concentration, tests it in -10 DEG C of environment
In ice storage.
Ice storage in the case of 1 different ratio of table
Regression equation are as follows: y=4.4x1+4x2+4.7x3-0.6x1x3+0.6x2x3+9x1x2x3, y is ice storage, x1, x2, x3
It is the mass percent of potassium acetate, sodium acetate and ammonium acetate respectively." programming evaluation " in Excel is recycled most preferably to be matched
Than: potassium acetate: sodium acetate: ammonium acetate=30%:32%:38%, theoretical ice storage can reach maximum value
4.81g。
Embodiment 2
The theoretical optimum proportioning that embodiment 1 obtains is optimized, by 30% potassium acetate, 30% sodium acetate and 40% acetic acid
Ammonium compounds deicing salt, specific as follows:
The raw material such as potassium acetate, sodium acetate, ammonium acetate are dried first, are ground when its constant temperature quality is unchanged
It is broken, be ground to it is powdered；
Then above-mentioned three kinds of raw material are weighed respectively by 30% potassium acetate, 30% sodium acetate and 40% ammonium acetate, be placed in
It can be sufficiently stirred in stirring container, be uniformly mixed it；
The mixture stirred evenly is dried again finally, pulverized, be ground to again after being dried to it
It is powdered, it is sealed；
Said mixture is configured to liquid spray-type snow melt agent solution by 20wt% concentration, tests it in -10 DEG C of environment
In ice storage, measured value 4.7g is not much different with theoretical value, can reach the ice-melt energy of sodium chloride, calcium chloride at -10 DEG C
90% or more of power, is shown in Fig. 1.
The deicing salt is tested to the corrosivity of carbon steel, the results showed that the corrosivity of carbon steel well below chloride salt deicing salt
(see Fig. 2).
Ice storage of the present invention, ice melting capability test method press " road deicing deicing salt GB/T 23851-2009 " the 4.5th
Section carries out.
The test method of corrosion of carbon steel rate of the present invention presses the rotating suspension of " the organic deicing salt JT/T 973-2015 of Lu Yongfei chlorine "
Piece method carries out.
Embodiment 3
It is with 2 difference of embodiment, mixture is configured to snow melt by the concentration of 10wt%, 20wt%, 30wt% respectively
Agent solution tests the pH value of snow melt agent solution under various concentration using acidometer, as a result such as table 2.
The pH value of 2 various concentration snow melt agent solution of table
The test method of pH value is by " road deicing deicing salt GB/T 23851-2009 " Section of 4.7 progress.
Embodiment 4
With reference to the seed germination experiment that SHAP-H-332 guide proposes, seed is Huang of the fraction 95% or more that germinate
Beans.The deicing salt prepared according to embodiment 2 is prepared into the deicing salt that mass fraction is 0.5%, 1.0%, 1.5% and 2.0% respectively
Solution handles soya bean, observes the germination percentage of soya bean, and measure the extended length of radicle, to indirectly evaluate the environmental protection of deicing salt
Characteristic, sodium chloride, the calcium chloride solution for furthermore preparing same concentrations do comparative experiments.As a result as shown in figure 3, various concentration condition
Under, the soya bean that snow melt agent solution of the invention is cultivated, germination is better than sodium chloride and calcium chloride solution.But work as solution quality
When score is 2.0%, the soya bean that sodium chloride solution and snow melt agent solution of the present invention are cultivated does not germinate, and what calcium chloride solution was cultivated
Radicle is extended.The result shows that deicing salt solution concentration can inhibit the sprouting of vegetable seeds when excessive, but compared to common chlorine
Salt deicing salt, snow melt agent solution of the invention want small to the development impact of vegetable seeds.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
