Abstract
The invention discloses a coal railway transportation dust depressor, which is invented for solving the problems of high cost, poor depression effect and so on in the prior art. The raw materials by weight percent for preparing effective compositions in the coal railway transportation dust depressor are: 2 to 7 percent of synthesized water-soluble polymer, 0.1 to 5 percent of modified cellulose water-soluble polymer, 85 to 95 percent of water and 0 to 2 percent of bluestone, wherein the synthesized water-soluble polymer is prepared by complexing at least two water-soluble polymers. The coal railway transportation dust depressor consists of more than two synthesized water-soluble polymers and a small amount of auxiliary agent, and has the advantages of high viscosity and low cost. When used, the coal railway transportation dust depressor is uniformly sprayed on particles on the surface of a coal bed to form a curing layer with certain strength, thereby the coal-dust particles of various grain sizes are bonded together and have certain toughness, and the aim of preventing flying dust on the surface of the coal bed is achieved.
Description
Technical field:
The present invention relates to a kind of railway Coal Transport dust-inhibitor and manufacture method thereof.
Background technology:
Along with going deep into of railway great-leap-forward development process, train running speed is greatly enhanced, and the transportation of the diffusing coal of railway accounts for whole volume of rail freigh 40%.Because at present in the way of railway carriage carry coal or other powder things, generally do not take to isolate powder and fly upward measure, unit train jolts and wind effect, the coal dust on surface and particle are by the car body that blows off, pollute both for railway environment along the line, and also caused waste also to bring sizable financial loss simultaneously to the owner of cargo to coal resources.According to statistics, in each hundred kilometers transportation of train in row 30 joint compartments, have nearly two tons of coals and run off, waft in the atmosphere that into we breathe, well imagine to the injury that human body brings.
In order to overcome above-mentioned problem, someone adopts paulin body periphery and vertical or horizontal with the method for tension rope colligation on the compartment mouth, prevented that effectively coal dust or other powder things from flying out with the wind in the compartment, reduced loss of material, and reduced pollution on the environment, but when using, it need artificial going on the compartment, to waste time and energy with these paulin colligations at every turn.
Also the someone attempts adopting the caking agents by making after the steaming heating such as polyethylene alcohol and water, when it uses, only need above-mentioned caking agent is sprayed at the surface, coal seam, to utilize reactive adhesive to excite the dust surfactivity, react with the dust active ingredient, generate adhesive layer, the top layer bisque is solidified, and have certain intensity, thereby reach the purpose of anti-airborne dust.This mode is very simple in use, has obtained user's favorable comment.But, can't obtain the high coating of bonding strength because the consolidation of its single dependence polyvinyl alcohol is subjected to the influence of polyvinyl alcohol molecular structure and molecular weight.Therefore this caking agent is long set time, and solidification effect is poor, and Fugitive dust covering flux more (the per car railway carriage or compartment reaches more than the 120 kg) is sprayed in the per car railway carriage or compartment has increased cost.
Summary of the invention
For overcoming above-mentioned defective, the object of the present invention is to provide that a kind of cost is low, set time is short, railway coal transportation dust-depressor that solidification effect is good and manufacture method thereof.
For achieving the above object, railway coal transportation dust-depressor of the present invention is made raw materials of effective components consisting of of percentage composition meter by weight: synthetic polymer 2-7, modified-cellulose class water-soluble polymers 0.1-5, water 85-95,0-2.
Wherein, described synthetic polymer is at least by two kinds of composite forming of water-soluble polymers.Like this, by the synergy of performance between polymkeric substance, the adhesive effect after the raising inhibitor is fixed.
Particularly, described synthetic polymer is by water-soluble poval and water-soluble sodium polyacrylate; Both are consisting of of percentage composition meter by weight: water-soluble poval 30-50, water-soluble sodium polyacrylate 50-70.
Particularly, described synthetic polymer is by water-soluble polyacrylamide and water-soluble sodium polyacrylate is composite forms, and both are consisting of of percentage composition meter by weight: water-soluble polyacrylamide 40-50, water-soluble sodium polyacrylate 50-60.
Particularly, described synthetic polymer is by water-soluble polyacrylamide and water-soluble poval is composite forms, and both are consisting of of percentage composition meter by weight: water-soluble polyacrylamide 40-50, water-soluble poval 50-60.
Particularly, described synthetic polymer forms by water-soluble sodium polyacrylate, water-soluble polyacrylamide and water-soluble poval are composite, the three is consisting of of percentage composition meter by weight: water-soluble sodium polyacrylate 30-50, water-soluble polyacrylamide 40-50, water-soluble poval 50-60.
For achieving the above object, railway coal transportation dust-depressor manufacture method of the present invention is put into 85-95 part normal-temperature water (20 ℃-30 ℃) in reactor; Add composite back water-soluble polymers 2-7; After being stirred to whole dissolvings, slowly add modified-cellulose class water-soluble polymers 0.1-5, be stirred to whole dissolvings, add copper sulfate 0.01-2 at last, stirring gets final product.
Among the present invention, adopt two or more synthetic polymers and a small amount of auxiliary to form, during use it evenly is sprayed on the coal seam surface particles, form a kind of cured layer with certain intensity, thereby the pulverized coal particle of various particle diameters is tied together, and have certain toughness, thus reach the purpose that prevents surface, coal seam airborne dust greatly, and its manufacturing is implemented very simple.
