新型煤粉抑尘剂的研究及应用

Preparation and Application of the New Type Dust Suppressant Used in Coal Transportation

为了更好的解决煤炭运输过程中的扬尘问题,采用高分子聚合物、水溶纤维素聚合物为原料,利用正交实验法研制了一种满足生态要求的集粘结、吸湿和保水为一体的复合型化学抑尘剂。通过测试该抑尘剂的抗风性能,结果表明:新型抑尘剂在常温下溶解性好,抑尘效果好,固化层具有一定的强度,具有实际应用价值。

In order to solve the dust prombles in coal transportation, a new type of composite chemical dust suppressant was developded, which used of water - soluble polymers, water - soluble cellulose polymers as the raw material and orthogonal analysis method. It met the ecological requirements, had good bonding performance, moisture absorption and water mainte- nance. The wind- resistant experiment results showed that the dust suppressant can dissolute at room temperature, and had good dust suppression, and the solidified layer had a certain strength. So the dust suppressant had practical application value.
