Description
【Technical field】
The invention belongs to environmental protection technical field.More particularly it relates to a kind of pollution-free road dust inhibitor, also
It is related to the application method of the pollution-free road dust inhibitor.
【Background technology】
It is well known that dust pollution is one of world's public hazards, and road dust is the pith in dust pollution.With regard to mesh
For preceding road surface airborne dust present situation, opencut highway is generally native stone or macadam pavement, and road quality classification is low, of poor quality, this highway
Subject matter be road surface dust suppression.When heavy-duty truck is run, the dustiness in air is up to 0.5~1g/m3More than, exceed
State health standards hundred times, cause serious dust pollution.City hard surface airborne dust is even more the main next of cities and towns reentrainment of dust
Source.At present, people have carried out numerous studies work to suppressing dust pollution, obtain certain progress, such as CN102660226 A public affairs
A kind of High-molecular polymer dust suppressant compound is opened, it is by cellulose family macromolecule compound, polyoxyethylene-type nonionic table
Face activating agent, glycerine, calcium chloride and water form.CN105602525 A disclose a kind of antifreeze coal dust inhibitor of collaboration moisturizing and
Its preparation method；The coal dust inhibitor is made up of binding agent, film forming agent, bleeding agent, NMF, flocculating agent, antifreeze and water.
CN105907373 A disclose a kind of magnetic dust suppressant, and it contains polyacrylamide, polyvinyl alcohol, guar gum, carboxymethyl cellulose
Sodium, lauryl sodium sulfate, sodium carboxymethyl starch and magnetic nanoparticle.But these dust suppressants are also asked in the presence of some technologies
Topic, such as some dust suppressants bonding adsorption effect are bad, and the lasting moistening effect time is short, and some hygroscopic salts have corrosivity,
Dust suppression cost is high.
In addition, main both at home and abroad at present suppress road surface airborne dust using sprinkling water law, watering is simple and convenient, but evaporation rate is fast
And action time is short, the demand of permanently effective dust suppression is can not meet to the big road surface of laying dust thickness.
Therefore, the present inventor is on the basis for summarizing prior art, when researching and developing one kind easy to use, useful effect
Between long, compound dust on the roads curing materials that cost is cheap, its economic indicator is suitable with spraying or better than spraying.

The particulate count evidence of gas monitoring point, and it is used as Atmospheric particulates background concentration using the data.Deduct Atmospheric particulates background concentration
Incrementss of the result obtained afterwards as pavement particles thing airborne dust.This is sprayed it can be seen from the result listed by upper table 8 and table 9
After inventing pollution-free road dust inhibitor, there is obvious reduction to act on the particle concentration of shortcut face scope, 8h average grains
Before thing concentration incrementss are significantly lower than sprinkling dust suppressant, during test, PM after road dust inhibitor of the present invention is sprayed10Be averaged and cut
Subtract ability up to 36.8 μ g/m3, PM2.5Average reduction ability up to 20.1 μ g/m3.Spray average of the 8h after road dust inhibitor
Grain thing concentration incrementss are continuously in negative value, and this, which illustrates to spray road dust inhibitor of the present invention, not only can effectively suppress vehicle and make
Into particle concentration rise, shortcut face scope atmosphere particle concentration can also be reduced.
This result of the test is listed in accompanying drawing 1.From accompanying drawing 1, completed in the pollution-free road dust inhibitor of the sprinkling present invention
After 15 days (January 30), being sprayed road surface still has good anti-dust effect, under the conditions of relatively low vehicle flowrate, sprays road surface
The continuous and effective time is up to 2 to 3 weeks after dust suppressant.
