Scientific novelty
The dust suppression composition includes polyvinyl acetate, which is a copolymer of vinyl acetate involving ethylene, acrylic acid, pyrrolidone, acrylate, vinyl alcohol, acrylamide, dihaloethane, or a combination of the above. It additionally contains polyethylene glycol with a molecular weight of 400 g/mol and water in the following ratio of components, wt.%: polyethylene glycol with a molecular weight of 400 g/mol - 0.95-1; polyvinyl acetate - 0.12-0.24; water - the remainder. The use of the proposed dust suppression composition allows for reducing the dusting of fine-grained materials (construction materials, ash, coal, slag, fertilizers, etc.) by up to 98% compared to untreated materials. Due to high dust suppression capacity and the formation of a polymer film on the surface, the possibility of re-dusting is eliminated.
Advantages
Can be applied for dust suppression in the mining, coal, construction, and other industries. The dust suppressant is designed to combat dust formation in quarries, on roads, and to prevent the dusting of various fine-grained materials (ash, coal, slag, potash and other fertilizers, etc.). The invention provides an increase in the dust suppression capacity of the composition and a long-term surface stabilization effect.
Commercial implementation
The main region for implementation of the development is universal. The use of the proposed dust suppression composition allows for a reduction in the dusting of fine-grained materials (construction materials, ash, coal, slag, potash, and other fertilizers, etc.) by up to 98% compared to untreated materials. Due to its high dust suppression capacity and the formation of a polymer film on the surface, the possibility of re-dusting is eliminated.
