Abstract
A snow-removing deicing agent is prepared by mixing calcium chloride, which is the by-product of producing alkali by using seawater and limestone, and bittern powder, which contains magnesium chloride as main component, with salt residue or high-low temperature salt as main component, wherein the calcium chloride is 1-4 parts, the magnesium chloride is 1-3 parts, the sodium chloride is 5-50 parts, and the contents of the calcium chloride, the magnesium chloride and the sodium chloride are calculated according to pure substances. Its advantages are low cost, high snow dissolving effect, and high utilization rate of snow-removing agent (1/2-1/5 of that of existing agent).
Description
The present invention is a kind of snow-removing and ice-thawing agent that is used for municipal highway, bridge snow-removing and ice-thawing.
Using the snow-melting agent snow removing is the widely used technology of modern city, not only can improve snow removing efficient but also can save manpower with its snow removing, but its major ingredient of snow-melting agent mostly is sea salt at present, this snow-melting agent defrost weak effect, only suit under subzero 15 ℃-subzero 17 ℃ of conditions, to use, as be lower than said temperature and just be difficult to use, this also is the major cause of severe cold areas without snow-melting agent, because the snow-melting agent major ingredient is a sea salt, cost is higher, and under the bigger situation of year sprinkling amount, fund input is surprising, just used 252570 tons of salt in 1 year as Wisconsin, USA, 552570 tons of salt have then been used in the Bin Xiniya state.Also have the salt of employing to add the snow-melting agent that the sand prescription is made, just use this kind snow-melting agent as Los Angeles, USA city, Chicago city, the disadvantage of this snow-melting agent is that the easily stifled outfall sewer that stagnates of sand is logical, the clear very difficulty of washing in a pan.In addition, existing snow-melting agent does not all contain covering agent, to bridge and vehicular traffic seriously corroded.
At the deficiency that above-mentioned prior art exists, it is low to the purpose of this invention is to provide a kind of cost, the few and snow-removing and ice-thawing agent that can use at severe cold areas of consumption.
The object of the present invention is achieved like this: it is that the halogen powder of magnesium chloride and salt quarrel that major ingredient is sodium-chlor or high and tow temperature salt are mixed by pay product calcium chloride and the major ingredient of producing alkali with seawater and Wingdale, wherein, calcium chloride is 1-4 parts, 1-3 parts in magnesium chloride, 5-50 parts in sodium-chlor, the content of above-mentioned calcium chloride, magnesium chloride and sodium-chlor is all by pure substance.
In order to make this snow-removing and ice-thawing agent be reduced to minimum level to the corrosion of bridge and vehicular traffic, in above-mentioned prescription, also can add micro-covering agent, this covering agent is a metal rust preventing water.
The invention has the advantages that: 1, raw material sources are extensive, and price is low, so its cost is corresponding lower; 2, owing to contain the magnesium chloride of the very strong calcium chloride of pour-point depressing process and the pour point depression moisture absorption effect of prewetting in the prescription, so its defrost is effective, can use being lower than under the subzero 20 ℃ condition, suitable severe cold areas snow-removing and ice-thawing, usage quantity is to have 1/2-1/5 of snow-melting agent now; 3, water-insoluble can prevent that less water drain is stifled stagnant; 4, the corrosion to bridge and vehicular traffic can be reduced to minimum level.
Below in conjunction with embodiment the present invention is specified.
This snow-removing and ice-thawing agent uses according to condition of different temperatures can be divided into two kinds of models.
First kind of model I type: temperature is used 1 part in calcium chloride, 1 part in magnesium chloride, 20-50 parts in sodium-chlor subzero more than 17 ℃.This snow-removing and ice-thawing agent is made grain.
Second kind of model II type: temperature subzero 17 ℃ with down to subzero 30 ℃ of uses, 3 parts in calcium chloride, 2 parts in magnesium chloride, 6-20 parts in sodium-chlor, this kind snow-removing and ice-thawing agent is made grain.
All can add the thousandth that accounts for total amount in the snow-removing and ice-thawing agent of above-mentioned two kinds of models to centesimal metal rust preventing water, i.e. urotropine and triethanolamine oleate.
In order further to improve the defrost effect, in above-mentioned prescription, also can add 1-4 parts zinc chloride.Making it still can defrost under subzero 40 ℃ of conditions.
Production technique of the present invention is as follows:
One, supplied materials analysis is measured the content of calcium chloride, magnesium chloride, sodium-chlor with general chemical process, is converted into each material component in the prescription by pure substance.
Two, 20 orders of pulverizing, sieve are following to get final product.
Three, weighing is put into the drum mixer mixing by ratio of components.
Four, spray adds covering agent, and mixing stirring is above-mentioned two times, makes its film degree attenuation become even.
Five, packing packs the above-mentioned mixed snow-removing and ice-thawing agent that gets or the special-purpose snow-eliminating agent spraying car of packing into.
Claims (3)
1, a kind of snow-removing and ice-thawing agent, it is characterized in that, pay product calcium chloride and major ingredient that it produces alkali by seawater and Wingdale are that the halogen powder major ingredient of magnesium chloride is that salt quarrel of sodium-chlor or high and tow temperature salt are mixed, wherein, calcium chloride is 1-4 parts, 1-3 parts in magnesium chloride, 5-50 parts in sodium-chlor, the content of above-mentioned calcium chloride, magnesium chloride and sodium-chlor is all by pure substance.
2, snow-removing and ice-thawing agent as claimed in claim 1 is characterized in that also adding micro-covering agent in above-mentioned prescription, and this covering agent is a metal rust preventing water.
3, ask 1 described snow-removing and ice-thawing agent as right, it is characterized in that in above-mentioned prescription, also can adding 1-4 parts of zinc chloride.
