Dust-reducing compositions for treating dry soil |
摘要 |
A dust-reducing composition for treating dry soil that includes a hygroscopic compound together with a hydrophobic compound in relative amounts sufficient to form a water-repellant surface on the soil. Also, a process for treating dry soil to reduce dust generation due to movement of traffic or air thereover. This process includes applying onto the soil a hygroscopic compound and subsequently applying a hydrophobic compound onto the hygroscopic compound containing soil. Alternatively, the process includes applying onto the soil an aqueous solution of a mixture of a hygroscopic compound and a hydrophobic compound. In either case, the hygroscopic and hydrophobic compounds are applied in relative amounts sufficient to form a water-repellant surface on the soil.
