Description
Technical field
Fixed the sand dust suppressant the present invention relates to building, greening building site etc. dust control technology field, more particularly to a kind of environment-friendly type
And its application method.
Background technology
During industrialized, prevent and remedy pollution, environmental protection has turned into the powder of the fundamental state policy, construction site etc. in China
Dustiness dye is to cause one of main contributor of atmosphere pollution, and in recent years, ecological environment is destroyed in China, and desertification is seriously sent out
Exhibition, ground lack vegetation protection, the situation getting worse of sandy soil airborne dust, with the development of economic construction of China, the highway in China,
The capital construction such as railway, hydraulic engineering, high-rise building are substantially accelerated, the sand and dust dust pollution question for the air quality thus brought
It is increasingly serious, environmental degradation is caused, aggravates the formation of haze.
During current city optimization is built, after building is removed, the exposed loess of large area, the dust pair kicked up are left
The dustiness of air is very big, has had a strong impact on the life of nearby residents, typically carries out Air Filter covering to loess exposed area at present
And processing of sprinkling water, not only cost is high for Air Filter, human cost is high, it is often more important that Air Filter will portion once Ultraviolet light exposure
Decompose, then swayed through exposing to wind and rain with regard to unordered, still sand and dust blow all over the sky strong wind, and Air Filter rolls easy breakage through vehicle, need
Will cover net repeatedly, waste a large amount of manpower and materials, Air Filter due to itself being all mesh, can only mitigate to a certain extent blown sand,
Flying dust phenomenon, dust-proof effect is poor, and the dust-proof cycle is short；Air Filter cost itself is high, and process of deployment needs substantial amounts of cost of labor,
Under the mal-conditions such as high temperature, strong wind, the burden of long working outside staff room is considerably increased, sole mass light one blows
Will turnup around rolling together, there is wind state not to be fixed easily；Moreover Air Filter is all that plastic material makes, by ultraviolet irradiation just
Can decomposed, into soil after form secondary non-degradable plastic pollution environment, lasting for years is non-degradable and non-recovery is worth,
Watering dedusting operation more makes us make the matter worse water-deficient area；Generally speaking, sprinkled water used by target, cover doing for Air Filter
Method is very limited for the anti-dust effect of loess exposed area, is repeatedly uninterruptedly sprayed with water and showed for water resource is more and more in short supply
Shape is disagreed with environmental protection.
The present invention discloses a kind of environment-friendly type and fixed the sand dust suppressant and its application method, and its theory is the suppression of fixing the sand by science
Dirt agent prescription is sprayed onto in the scope of operation, and so as to allow the scope of operation can not crust dust and sand, condensate face is formed under shell so as to allow grass-seed to give birth to
Long germination, it is small careless luxuriant to allow environment to reach anti-dust effect, and sustainable application, Ecological dust suppression environment construction by restoration of the ecosystem
Framework, and thereby as the main helper of haze is effectively administered, the dust suppressant that fixes the sand is that a kind of Water Soluble Compound type ring of synthesis is protected
Preparation, available for preventing and treating blown sand, flying dust, they are sprayed in sandy soil dust, can be increased the hardness of soil, be made soil block,
Increase water solubility and cohesiveness, prevent sandy soil from being corroded by water, wind, reduce the volatilization and loss of moisture, promote plant growth, fix the sand
Dust suppression dispensing, use is nontoxic, prepared by non-corrosive environment-friendly materials, and synthetic method is simple, easy to use, high-efficiency environment friendly,
The dust suppressant that fixes the sand, which is in the normal state down, relatively to be stablized, the dust suppression term of validity of fixing the sand length.
The content of the invention
Fixed the sand dust suppressant and its application method it is an object of the invention to provide a kind of environment-friendly type, the dust suppressant that fixes the sand can be used for preventing
Blown sand, flying dust are controlled, they are sprayed in sandy soil dust, can be increased the hardness of soil, be made soil block, increase water-soluble and solidifying
Poly- power, prevent sandy soil from being corroded by water, wind, reduce the volatilization and loss of moisture；Fix the sand dust suppression dispensing, use is nontoxic, non-corrosiveness
Environment-friendly materials prepared, synthetic method is simple, easy to use, high-efficiency environment friendly, and the dust suppressant that fixes the sand is in the normal state down more steady
It is fixed, the dust suppression term of validity of fixing the sand length.
