Abstract
The invention relates to the technical field of snow-melting agents, and relates to a snow-melting agent. The snow-melting agent is prepared from magnesium chloride, anhydrous calcium chloride and silicate according to the mass ratio of 1:(0.1-0.5):(0.1-0.5). The invention further provides a preparation method of the snow-melting agent; the preparation method comprises the following steps: I, crushing anhydrous calcium chloride until the practical size of the crushing anhydrous calcium chloride is 1-2 mm; II, mixing the magnesium chloride, the anhydrous calcium chloride and the silicate according to the mass ratio of 1:(0.1-0.5):(0.1-0.5), and uniformly stirring. The novel snow-melting agent provided by the invention is wide in raw material resource, low in cost and water-absorbing and anti-sliding. As the tailings generated after a potash fertilizer is prepared are adopted as a constituent component magnesium chloride, the waste resource is utilized, the environment can be protected, and the cost is low.
Description
Technical field
The present invention relates to snow melt technical field, refer in particular to a kind of Snow Agent and preparation method thereof.
Background technology
Urbanization and highway are the important symbols of social progress and development, and the fast-developing city of country of some advanced technology and highway communication, automobile becomes the main body vehicles then.Therefore Urban traffic and highway communication occupy special consequence in the national economic development.
Winter Snow sky causes traffic difficulties, particularly jeopardize personnel safety, deal with improperly or not in time, city, area and even national Economic development can be affected, affect the orthobiosis of the people simultaneously, even can cause the generation of local " paralysis " and big area " accident ".Therefore, the snow melt of timelyization ice has great society, economy and national defence meaning.See with regard to world today's situation, except snow removal with machine and artificial except, up to the present adopt villaumite Snow Agent (change cryosel) to be still main deicing or snow melting technique means.
According to the difference of main chemical in Snow Agent, be roughly divided into three major types: chloride salt, non-chloride salt, environmental protection mixed type Snow Agent.Bring into use Snow Agent the thirties in 20th century abroad, wherein main take sodium-chlor as the maximum of Snow Agent.The major ingredient that the U.S., Canada and European Countries use is the rock salt with sodium-chlor, and what the sixties in 20th century, Japan brought into use sodium-chlor early application is evaporate brine day to melt except road snow mantle.The current U.S. uses five kinds of Snow Agent, and three kinds is belong to villaumite type (sodium-chlor, calcium chloride, Repone K), and two kinds is non-villaumite type (magnesium acetate calcium and urea).Usage quantity was maximum at that time, duration of service is the longest was chloride salt Snow Agent, and its usage quantity accounts for more than 90% up till now, and sodium-chlor is still occupied an leading position as Snow Agent.Japan uses sodium-chlor as melting agent, until nineteen ninety-five brings into use calcium chloride.Along with Snow Agent in use produced problem, people start searching and have deicing or snow melting effect, again the non-chloride salt Snow Agent of not chloride ion-containing, i.e. non-chloride salt ions Snow Agent (magnesium acetate calcium, Potassium ethanoate, urea, dibasic alcohol etc.).
Abroad in Recent Years is studied in achloride type Snow Agent, producing acetate, utilizing papermaking wastewater to produce composite snow-melting agent utilizing junk.Terence E P has invented the Snow Agent of LMW BL and has obtained patent, Todd A B] patent be utilize molasses for desugarization processing in waste as Snow Agent.Obtained a kind of liquid Snow Agent in the by product of the people such as SatvaP C in fatty acid ester processing, the people such as Robert A H invent a kind of anticorrosion type Snow Agent in by product BCS, DCS, CCSL of deep processing of farm products.KrisA B etc. makes a kind of low-corrosiveness Snow Agent.
In mixed type Snow Agent, Robert A H, James D S, Robert S K etc. utilize various processing waste to classify after treatment to add in main raw material and carry out snow melt to slow down Snow Agent road pavement and bridge erosion on the basis of original Snow Agent.
In the Snow Agent of chloride salt, the cost of sodium-chlor, calcium chloride is lower, but environmental pollution is serious; The deicing salt on environment less pollution of non-chloride salt, but cost is high, and preparation technology is also comparatively complicated, only uses in specific occasion at present, such as airport, motorway etc.; The pollution of mixed type deicing salt on environment is between chloride salt and non-chloride salt, and technique is also comparatively complicated, and cost is high.Further, most at present situations employs after Snow Agent makes ice dissolution and form a large amount of ponding on road surface, makes troubles to traffic.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of Snow Agent, comprising magnesium chloride, Calcium Chloride Powder Anhydrous and silicate that mass ratio is 1:0.1 ~ 0.5:0.1 ~ 0.5.
Further, the particle diameter of described Calcium Chloride Powder Anhydrous is 1 ~ 2mm.
Further, the particle diameter of described Snow Agent is 0.5 ~ 1.5cm.
The present invention also provides a kind of preparation method of Snow Agent, comprises the steps:
Step one, Calcium Chloride Powder Anhydrous being crushed to particle diameter is 1 ~ 2mm;
Step 2, by magnesium chloride, described Calcium Chloride Powder Anhydrous and silicate according to mass ratio be 1:0.1 ~ 0.5:0.1 ~ 0.5 ratio mixing, stir.
Further, the particle diameter of described Snow Agent is 0.5 ~ 1.5cm.
New Kind of Solvent of Snow-melted provided by the invention, raw material is easy to obtain, and cost is low.Water suction, anti-skidding.Moiety magnesium chloride wherein adopts the mine tailing after producing potash fertilizer, and utilize waste resource, be conducive to environment protection, cost is low; Calcium Chloride Powder Anhydrous has water sorption, and the ponding formed after ice dissolution is less; Dry powder silicate then has anti-skidding effect, guarantees road traffic safety.
Embodiment
To elaborate to the embodiment of the present invention below.
A kind of Snow Agent that the present embodiment provides, at least comprises magnesium chloride, Calcium Chloride Powder Anhydrous and dry powder water glass, and wherein, magnesium chloride, Calcium Chloride Powder Anhydrous and dry powder water glass mass ratio are 1:0.1 ~ 0.5:0.1 ~ 0.5.
The preparation method of the Snow Agent of the present embodiment, comprises the steps:
Step one, prepares raw material.Calcium Chloride Powder Anhydrous being crushed to particle diameter is 1 ~ 2mm.The magnesium chloride raw material that the present embodiment adopts is from producing the mine tailing after potash fertilizer (being called for short potash fertilizer mine tailing) (main component comprises magnesium chloride 90% ~ 95%, other impurity such as sodium-chlor, sandy soil etc. account for 4 ~ 9%).Those skilled in the art can converse the proportionlity of potash fertilizer mine tailing and Calcium Chloride Powder Anhydrous, silicate according to the content of magnesium chloride of potash fertilizer mine tailing.
Step 2, be the ratio mixing of 1:0.1 ~ 0.5:0.1 ~ 0.5 according to mass ratio by described potash fertilizer mine tailing, described Calcium Chloride Powder Anhydrous and silicate, stir, obtaining particle diameter is the spherical Snow Agent of 0.5 ~ 1.5cm.
