Abstract
A raised dust solidification method is disclosed. According to the invention, polyvinyl acetate, polyvinyl alcohol or vinyl acetate-ethene is used for raised dust solidification. By the method for solidification of dust and raised dust generated from constructional engineering, construction sites, mining fields and ash slag dumps and during power transmission, dust hazard of field operation is reduced, the influence of dust and raised dust on air quality and the ecological environment is minimized, and the ecological environment and living environment are improved.
Description
Technical field
The present invention relates to a kind of method of Environment control, be specifically related to a kind of method of Environment control dust.
Background technology
Along with urban construction, various basic industry build flourish, a large amount of dust that construction work, building site, building site, mine, grey cinder yard and band powder material transport point produce and airborne dust, have a strong impact on operating environment and Air quality, threatened that operating personnel and neighbouring resident's is healthy.Main employing is sprayed water and some simple formulations dust suppressions at present, and the hold-time is short, Gu airborne dust weak effect.
At present, vinyl acetate polymer and derivative product thereof are mainly used as the traditional field such as sizing agent, coating, paper, chewing gum base and fabric finishing agent.
Summary of the invention
The object of the invention is a kind of method providing efficient, easy solid airborne dust, below all with parts by weight.
The object of the invention is achieved through the following technical solutions:
A method for solid airborne dust, is characterized in that: adopt the solid airborne dust of polyvinyl acetate (PVA), polyvinyl alcohol or vinylacetate-ethylene.
Those skilled in the art know and clearly, polyvinyl acetate (PVA) refers to the polymkeric substance of Vinyl Acetate Monomer homopolymerization, can be obtained by solution polymerization, letex polymerization, suspension polymerization or mass polymerization, if desired can the auxiliary agent such as additional plasticizer, solvent.
Preferably, after being mixed with 85-98 part water by 2-15 part polyvinyl acetate (PVA), spray solid airborne dust, after being mixed with 85-98 part water by 2-15 part polyvinyl alcohol, spray solid airborne dust, after being mixed with 85-98 part water by 2-15 part vinylacetate-ethylene, spray solid airborne dust.
Specifically, solid airborne dust of the present invention is dust or the airborne dust that building site, admittedly various mine produces (as colliery, metallurgical ore deposit, limestone mine, calcium carbide ore deposit, asbestos deposit, stone quarry, rubble field etc.), effectively reduces or eliminates airborne dust.
Solid airborne dust of the present invention is solid building, the dust of building site or airborne dust, avoids or the generation of restraining airborne dust and the harm brought thereof.
Solid airborne dust of the present invention is solid generation dust, the dust of factory (as steelworks, fuel-burning power plant, cement mill, glasswork, dry-mixed mortar factory etc.) of dust heap or slag field or airborne dust, effectively reduces or eliminates airborne dust.
Solid airborne dust of the present invention is dust or the airborne dust on the contained material surface of solid vehicle, railway carriage or steamer, has both alleviated environmental pollution, has additionally reduced material loss in transit.
Enforcement of the present invention, is mainly reflected in the great progress of generation and significant effect ecological, environmental protective:
(1) the inventive method is adopted to suppress dust, the airborne dust produced in construction work, building site, building site, mine, grey cinder yard and powder transport, decrease the dust hazard of site work, reduce the impact on Air quality and ecotope of dust airborne dust, improve ecotope and human residential environment.
(2) the present invention's vinyl acetate polymer or derivatives thereof used, belongs to safety and environmental protection, nontoxic water-latex type or water-soluble products in high molecular synthetic material, to plant, animal, microorganism all without harm, does not produce any secondary pollution.The present invention's polymkeric substance or derivatives thereof used, owing to being water-latex type or water-soluble products, being convenient to dilute with water and spraying construction very much, both can the manual spraying operation of small area, and also big area mechanize can spray construction, flexibly and easily, simple and effective, very easily implements.
Embodiment
Below by embodiment, the present invention is specifically described, what be necessary to herein means out is that following examples are only used to further illustrate the present invention, limiting the scope of the invention can not be interpreted as, without departing from the spirit and substance of the case in the present invention, the amendment do the inventive method, step or condition or replacement, all belong to scope of the present invention; Below all with parts by weight.
the wind tunnel experiment of the embodiment 1 dust grains of sand
Get municipal construction road dust on both sides of the road as sample, the plastic disc filling being of a size of Φ 20cm × 4cm with 15, with glass stick along on plate along floating.Respectively 10 parts of polyvinyl alcohol, vinylacetate-ethylene emulsion, aqueous polyvinyl acetate emulsion respectively with 90 parts of water are mixed, according to 1kg/m
2consumption be sprayed at dust on the surface, put into wind-tunnel after drying.Getting deflation angle is respectively 0 °, 15 °, 30 °, deflation 10 minutes under wind speed is 15-16m/s condition.Test sample wind erosion weight is 0-3wt%, 1-2wt%, 1-3wt%, and all samples bonding course surface serviceability rate reaches 97.2%, 96.4%, 94.5%.
the deflation of embodiment 2 with particulate dust is tested
Being 32cm × 22cm × 4cm at laboratory size, Stainless Steel Disc loads sand, sandy soil, dust, coal ash, each 9 dishes of concrete grey respectively, each plate along on plate along floating.Get 8 parts of aqueous polyvinyl acetate emulsions respectively, polyvinyl alcohol, vinylacetate-ethylene emulsion respectively with 92 parts of water mix, according to 1kg/m
2consumption be sprayed at surface formed bonding course, often organize sprinkling 3 coil.Getting deflation angle is respectively 0 °, 15 °, 30 °, and with the stronger fan deflation of wind-force 48 hours, test wind erosion weight was 0, and Sample consolidation layer surface serviceability rate is 100%.
embodiment 3 is with the consolidation test of particulate dust under natural wind condition
Load sand, sandy soil, dust, each 9 dishes of coal ash, concrete grey respectively with the Stainless Steel Disc being of a size of 32cm × 22cm × 4cm, each plate along on plate along floating.Get 8 parts of vinyl acetate-acrylate copolymer emulsions and 92 parts of water mix, according to 1kg/m
