[0002] China's railway coal and mineral powder transportation is generally transported by gondola cars. Due to the bumps caused by roadbeds, turnouts and rail facilities, coupled with wind force, fine powder particles with a fineness of less than 30-40 mesh standard sieves are blown away from the car body and fall. After reaching the road surface, after being rolled by subsequent vehicles, secondary dust with smaller particle size and higher concentration will be formed, resulting in the loss of coal and mineral powder and pollution along the road
[0003] First, it will cause serious pollution to the environment along the line. The dust scattered along the line will generate secondary dust when the subsequent trains pass by, forming a pollution belt, which will affect the normal growth of crops and trees in the farmland within 30-80m on both sides of the railway. And it also produces serious pollution to the body of other vehicles passing by.
[0004] Second, it poses a threat to driving safety. When the train passes through the tunnel, even if the

Embodiment 1
[0043] First add 439.7kg tap water in the preparation tank, start stirring, then add 3.5kg pregelatinized starch, 0.4kg gellan gum, 1.0kg sodium carboxymethylcellulose, 0.25kg aluminum chloride, 0.4kg sodium aluminosilicate, 0.25kg of polyvinyl alcohol, stirred for 1.5h to fully dissolve each material to obtain the finished product.
Embodiment 2
[0045]First add 494.05kg tap water to the preparation tank, start stirring, then add 3.0kg pregelatinized starch, 0.35kg xanthan gum, 1.5kg sodium hydroxyethyl cellulose, 0.35kg sodium titanate, 0.45kg glucose, 0.30kg poly Acrylamide, stirred for 1.5h to fully dissolve each material to obtain the finished product.
Embodiment 3
[0047] First add 493.55kg tap water to the preparation tank, start stirring, then add 4.0kg pregelatinized starch, 0.25kg pullulan, 1.25kg sodium hydroxypropyl methylcellulose, 0.25kg sodium tetraborate, 0.4kg gas phase two Silicon oxide, 0.3kg polyvinyl alcohol, stirred for 1.5h to fully dissolve each material to obtain the finished product.
[0048] The glue used in existing dust inhibitor products is generally plant seed glue, compared with the performance of the microbial polysaccharide glue used in the present invention, it has the following differences:
[0049]
[0050]
[0051] It can be seen from the above table that microbial polysaccharide glue dust suppressant has higher heat resistance, acid and alkali resistance, salt resistance, enzymolysis resistance and wider applicability than plant seed glue dust suppressant.

Abstract
The invention provides an ecological environment-friendly dust inhibitor which comprises the following components by weight percent: 0.5-0.8% of modified starch, 0.05-0.10% of microbial polysaccharide, 0.1-0.3% of cellulose derivative, 0.05-0.10% of netty accelerant, 0.05-0.15% of flow dispersant, 0.01-0.10% of film forming agent and 98.0-99.0% of water. The dust inhibitor can enable coal or mineral powder to form a layer of curing film on the surface, is high in viscosity and low in wind erosion rate, can avoid the flowing dust pollution and the flowing dust loss of the coal or the mineral powder to the way side in the railway transportation process, and has a huge economic benefit and a social benefit of environmental protection for railway transportation and coal or mineral powder customers; and the components and a solution of the dust inhibitor do not have any toxic side effect and corrosive effect, the dust inhibitor does not cause any secondary pollution as the dust inhibitor can be quickly and biochemically degraded in the nature after the dust inhibition action period, and the soil can be properly improved.
Description
technical field [0001] The invention relates to the technical field of dust suppression, in particular to an eco-friendly dust suppressant, which is used for dust suppression in railway coal and mineral powder transportation, and can also be widely used in the suppression of dust in mine roads, urban roads, construction sites, station wharves and the like. Background technique [0002] China's railway coal and mineral powder transportation is generally transported by gondola cars. Due to the bumps caused by roadbeds, turnouts and rail facilities, coupled with wind force, fine powder particles with a fineness of less than 30-40 mesh standard sieves are blown away from the car body and fall. On the road, after being rolled by subsequent vehicles, secondary dust with smaller particle size and higher concentration will be formed, resulting in the loss of coal and mineral powder and pollution along the road. [0003] First, it will cause serious pollution to the environment along...
