Abstract
Environment protecting snow melting agent include the components of magnesium nitrate 50-300 weight portions, carbonyl amine 20-150 weight portions, calcium hydrophosphate 180-320 weight portions and ammonium nitrile 120-275 weight portions. Its production process includes the following steps: dissolving magnesium nitrate in water through stirring, dissolving carbonyl amine, calcium hydrophosphate and ammonium nitrile successively in the solution, stagnation and eliminating precipitate. The product has low cost, high snow solubility and no erosion.
Description
The invention belongs to a kind of snow melting agent and manufacture method thereof, particularly a kind of snow melting agent and manufacture method thereof with environment-friendly function, this product is mainly used in the ice and snow of removing on the road surface.
Form ice and snow the winter of severe cold on the road surface of being everlasting, make troubles to traffic.The mode of removing ice and snow at present has two kinds basically, promptly artificial deicing and molten snow agent deicing, because artificial deicing labour intensity is big, untimely, so people extensively adopt the snow melting agent deicing.Traditional snow melting agent is the villaumite type, its main drawback is to corrode road surface, mechanical means and hinder the growth of flowers, plants and trees, for this reason, the snow melting agent of the non-villaumite type of the employing that has removes the snow, as application number be 99109322.4, invention and created name is the application for a patent for invention of " agent for quick melting snow or ice and preparation method thereof ".The agent for quick melting snow or ice of being made up of bicarbonate of ammonia, red phosphorus, Repone K, nitrocalcite, magnesium nitrate, ethylene glycol etc. is disclosed in this patent application, though solved the erosion problem of villaumite type snow melting agent, but also have following shortcoming: it is low to dissolve ice and snow efficient, does not almost have dissolving power under-15 ℃ of conditions; System is joined complexity, the cost height, and inconvenience is popularized; Flowers, plants and trees also there is in various degree erosion action.
The purpose of this invention is to provide that a kind of product cost is low, solubleness is high, the environment protecting snow melting agent of no erosion action and manufacture method thereof.
Technical solution of the present invention is: a kind of environment protecting snow melting agent, it comprises following composition: magnesium nitrate, carboxamide, secondary calcium phosphate, ammonium nitrate, and its weight proportion is: 50～300 parts of magnesium nitrates, 20～150 parts of carboxamides, 180～320 parts of secondary calcium phosphates, 120～275 parts of ammonium nitrates.
The manufacture method of the molten snow of described environmental protection agent comprises the steps:
A, with the dissolving of magnesium nitrate and water Hybrid Heating,
B, in lysate, add carboxamide, secondary calcium phosphate, ammonium nitrate successively and make its dissolving,
C, leave standstill,
D, sediment exclusion.
Described magnesium nitrate and water Hybrid Heating are dissolved as and are heated to 90～100 ℃ and stirring.
The described carboxamide, secondary calcium phosphate, ammonium nitrate of adding successively in lysate makes it be dissolved as that to keep temperature be 90～100 ℃, stirs simultaneously.
Described time of repose is 0.5～2 hour.
Carry out drying behind the described sediment exclusion and make product become solid-state, its water ratio is less than 5%.
The present invention compared with prior art has following advantage: this snow melting agent is applicable to various traffic routes, and cost is lower than the villaumite type or the non-villaumite type snow melting agent of present use; The solubleness height, under-15 ℃ of conditions, thickness is 100 millimeters, and area is the road surface of 1 square metre of ice and snow, only can dissolve ice and snow with 30 these products of gram, and under-20 ℃ of conditions, the ice and snow of above-mentioned equal volume only can dissolve with 50 these products of gram.Icy water after the dissolving is excellent chemical fertilizer to the trees flowers and plants, and other any objects are not all had erosion action, is beneficial to environment protection, prepares very simply, and cost is low.
Below in conjunction with embodiment the present invention is further described:
1, earlier the 75Hg magnesium nitrate is put into reactor, add water 425kg again, heat temperature raising to 100 ℃ stirs simultaneously and makes it to be dissolved into lysate.
2, in lysate, add amine carbonate 85kg, secondary calcium phosphate 250kg, ammonium nitrate 179.5kg successively.In this process, make in the reactor that to keep temperature be 100 ℃, and stirring and dissolving becomes lysate.
3, leave standstill 75 minutes.
4, sediment exclusion.
After finishing above-mentioned operation, just can obtain liquid environment protecting snow melting agent.
Can adopt dryer liquid towards environment protecting snow melting agent to carry out drying, make liquid product become solid-state one-tenth lenticular, the crystal water content is carried out metering packing again and is got final product for being advisable less than 5%.
