Abstract
The invention discloses a kind of coal piling dust-proofing agent, the weight percent group of each component becomes：
Description
Technical field
The present invention relates to a kind of dust-proofing agents, more particularly to a kind of coal piling dust-proofing agent.
Background technology
With the development of science and technology with the progress of the mankind, electric power increasingly becomes the essential resource of people.Current hair
Power plant, which much still needs, relies on a large amount of coal resources, this just needs to carry out largely exploitation, storage and transport etc. to coal,
The heap coal yard in power plant, mine under normal conditions etc., majority are stored in open space.Under the action of the wind, surface layer powder
Dirt is flown upward, and is influenced site work environment, is also influenced surrounding enviroment.And the transport of coal relies primarily on railway, due to transporting coal patent
It is typically not closed, when the vehicle is running since the effect of wind-force causes the coal dust of coal surface to be blown afloat, will pollute
The loss of coal resources and the pollution of environment are caused in building, farmland of Along Railway etc..Therefore transport, the storage etc. of coal
Prevent coal dust from having been blown afloat into a urgent problem to be solved in occasion.
Having no very ripe experience both at home and abroad at present can use for reference, some are covered using tarpaulin etc. at present, more
Several measures, which is spray water mist, reduces dust, waste water resource, and effect is limited；In addition, for power plant soot, moisture increases
Can also low heat valve be reduced.There are also be to utilize covering agent, such as a kind of technology of Japan is to utilize polyacrylic acid
The surface of coal is sprayed at after ester and starch graft copolymer fusion, but the amount of its sprinkling is one kilogram every square metre, cost
It is very high, it is unfavorable for largely using and promoting.
Invention content
A kind of the purpose of the present invention is to provide material sources extensive, at low cost, good dustproof effect coal piling dust-proofing agent.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
The weight percent group of a kind of coal piling dust-proofing agent, each component becomes：
The coal piling dust-proofing agent is made using following methods：100 parts by weight meters, are thrown by number into blender successively
Enter reverse osmose pure-water, modified starch, sodium carboxymethylcellulose, isomeric alcohol polyethenoxy ether, isothiazolinone, stirs 3-5 minutes
It can be used afterwards.
The coal piling dust-proofing agent is uniformly sprayed on using mobile spray appliance according to the amount of 90~180 grams every square metre of stoste
The surface of dump.
The technical principle of the present invention is as follows：
Modified starch can be good at being dissolved or dispersed in water, form colloidal solution or emulsion liquid, have nontoxic, former
Expect that source is wide, price low the advantages that being readily biodegradable, is used as binder in the present invention.
Sodium carboxymethylcellulose belongs to the sodium salt of carboxymethyl cellulose ether, belongs to anionic cellulose ether, for white or breast
White fiber sprills or particle, 0.5-0.7 grams/cc of density is almost odorless, tasteless, has hygroscopicity, is readily dispersed in
It is used as binder at clear gum solution in water, therefore in the present invention, resists dignified dose again.
Isomeric alcohol polyethenoxy ether is colourless or weak yellow liquid, soluble easily in water, and emulsifying capacity is strong, high surface activity, is resisted
Hard water, chemical stability and Environmental compatibility are good in wider pH range, therefore are used as emulsifier in the present invention.
Isothiazolinone is to serve to kill livestock by disconnecting the key of bacterium and algae protein matter.Isothiazolinone with it is micro-
After biological, promptly can irreversibly inhibit growth, so as to cause the death of microbial cell, therefore to common bacteria,
Fungi, algae etc. have very strong inhibition and killing effect.It kills livestock efficient, degradability is good, has and does not generate residual, operation peace
Entirely, the features such as compatibility is good, stability is strong, use cost is low.It can be with chlorine and most of anions and canons and non-ionic surface active
Agent is miscible, and isothiazolinone has remarkable result to biological clay stripping, therefore is used as commercial sterilization mould proof in the present invention
Agent uses.
Above-mentioned four kinds of components are all hydrophilic, are dissolved in reverse osmose pure-water and form lotion, are conducive to spraying operation.
The present invention has compared with other products to be had the advantage that：
1, cohesiveness is strong, can close coal seam well, coal dust is avoided to disperse, and avoids pollution environment and coal resources
Waste；
2, at low cost, making material derives from a wealth of sources, and manufacture craft is simple, can widely apply；
3, each component degradability is good, has and does not generate that residual, safe operation, compatibility are good, stability is strong, will not be to coal
The burning of charcoal causes undesirable influence, burning that will not generate pollution.
Specific implementation mode
