Dust-depressor and preparation thereof

Abstract

The invention relates to a dust inhibitor, in particular to a dust inhibitor with remarkable dust inhibiting effect and a preparation method thereof, and belongs to the technical field of controlling environment pollution. The dust inhibitor comprises the following components in weight portion: 91.5 to 99.29 portions of water, 0.5 to 5 portions of polyvinyl alcohol re-dispersible gelatin powder, and 0.2 to 3 portions of carboxymethyl cellulose. The preparation method comprises the following steps: adding the polyvinyl alcohol re-dispersible gelatin powder and the carboxymethyl cellulose into a container according to the weight portion, fully stirring and mixing the mixture; and slowly adding the water into the mixed powder and stirring the mixture to dissolve fully, and obtaining the finished product of the dust inhibitor. The dust inhibitor has the advantages of no toxicity, no harm, no corrosiveness, scientific and reasonable formulation, simple preparation technology, low cost, safety, environmental protection and energy conservation; when the dust inhibitor is sprayed on the surface of a material, continuous hard shells can be formed on the surface and have certain strength, and the scattered material is sealed under the hard shells, so the dust inhibitor has dust-proof function; and the dust inhibitor has extensive economic and social benefits.

Description

technical field [0001] The invention relates to a dust suppressant, in particular to a dust suppressant with remarkable dust suppression effect and a preparation method thereof, belonging to the technical field of environmental pollution control. Background technique [0002] As we all know, during the production process of enterprises, a large amount of bulk materials, such as coal, ore or other raw materials, are often stored or transported. These bulk materials are easy to blow up with the wind when they are stacked or transported in the open air. Flying dust not only pollutes the air, endangers human health, but also causes material loss and economic losses for enterprises. Dust may also cause safety accidents. In the open-air coal storage plants of some thermal power plants, due to the flying coal dust, the heating pipes, cables, etc. may cause fire hazards due to the spontaneous combustion of deposited dust; the flying or splashing of bulk materials during railway tr...

AI Technical Summary

Problems solved by technology

[0003] The existing solution is to cover the bulk material with tarpaulin or sprinkle water, but neither can effectively solve the problem. Covering the tarpaulin reduces the operating efficiency, makes recycling difficult, and the cost is high; water sprinkling can only prevent dust for a short time, and frequent watering is required. This method is a serious waste of energy, and it cannot prevent dust and splash for long-term stacked materials and long-distance transported bulk goods.
